Thanks, Ted, and good morning, everyone. EVgo has another strong quarter, wrapping up a tremendous first year as a public company. We made significant progress in solidifying our position as the nation's largest public fast charging network for electric vehicles in a rapidly growing EV market. I'd like to begin this morning with some observations about the EV industry, given the escalating market momentum and enthusiasm we're seeing across the U.S. In 2021 alone, the market share of electric vehicles more than doubled, along with U.S. driver purchases of EVs. Approximately 475,000 electric vehicles were purchased in the U.S. last year, roughly double the sales from just the year before. This is just the beginning.
Auto manufacturers are planning to introduce approximately 50 new EV models just over the next 24 months, including the arrival of EVs in segments like SUVs and pickup trucks that will unlock new demographic frontiers in EV adoption. By 2025, dozens more will follow, creating an abundance of EV choice for every type of driver. We expect these trends will be further accelerated by tailwinds in the macro environment, as electrification of transportation has never been more widely accepted and anticipated. The improving cost and breadth of offerings comes at a time when rising commodity prices makes EV ownership more economically attractive than ever. As the pace of EV adoption accelerates, forecasters expect annual EV purchases to triple by 2025 and then triple again by 2030. It's worth remembering that we expect the demand for DC fast charging to outpace this already rapid market growth.
Automakers are meeting the consumer demand for fast charging solutions with battery technologies capable of supporting significantly higher levels of charging throughput. With EVgo's growth and ability to scale profitability tied to EV adoption, we are energized by the powerful secular trends bringing more EVs to the road. Everything we're witnessing across the industry reinforces our confidence in this market and EVgo's leading position within it. It's why we have more conviction than ever in the investments we're making and the plan we're executing against. Let me now highlight some of EVgo's remarkable accomplishments in fiscal year 2021. We delivered 26.4 GWh of charging throughput, a 68% increase over 2020. This demand for EVgo's charging services led to $22.2 million in revenue, a 52% increase over 2020.
We ended the year with 340,000 customer accounts as more drivers chose EVgo as a key charging partner, up from 231,000 at the start of 2021. This equates to about 80% of non-Tesla EVs sold in the U.S. last year coming to EVgo. This demand for EVgo and our charging services extends past individual drivers and is illuminated by our numerous partnerships throughout the industry, further cementing our market leadership in the EV charging space. We hear it time and again when potential partners call us, and we're often that first phone call they make. They recognize EVgo's experience, track record, and leadership position. Over the last year, we signed several new landmark partnerships with key OEMs, including Subaru and Toyota. EVgo is now the charging partner of automakers responsible for over 40% of U.S. light-duty vehicle sales.
As each of these OEM leaders ramps their own EV production, EVgo is exceptionally well-positioned to be the charging network of choice for new EV drivers. We've also grown our fleet business with numerous new and expanded partnerships that include Uber, Merchants Fleet, and leaders in the autonomous vehicle space. We're introducing our EVgo eXtend business line to the market today, an offering we're extremely excited about. Operationally, we ended the year with over 1,600 DCFC stalls in operation and increased the size of the EVgo development pipeline to approximately 3,100 new stalls, marking a 26% rise since the end of the third quarter in this crucial element of our growth story.
Over the longer term, we have a funnel of approximately 4,000 additional sites, each to host at least four charging stalls, which represents close to 5x the number of fast-charging station locations we currently operate. In terms of technology, EVgo continues to add value to our infrastructure business by developing innovative software products that attract new customers and deepen relationships with existing drivers and B2B partners. This includes the rollout of EVgo Optima, our customized software for fleets, a new mobile app, and EVgo Inside, our proprietary software and API suite, all designed around the same principle of anticipating how to meet our customers' charging needs in a comprehensive and intuitive way. In short, EVgo has been busy in 2021, laying the foundation for a comprehensive electrified transportation future. I'll return to these achievements and expansions of our business with some more detail in a few moments.
Let me now touch on the passage of the federal government's infrastructure legislation in November, an important moment that will certainly generate material effects. The National Electric Vehicle Infrastructure Program, or NEVI, will allocate $5 billion to states over the next five years, with an initial $615 million being made available later this year. This federal support to fast charging infrastructure may cover as much as 80% of a project's cost and may include coverage of operating costs as well as capital expenditures. The federal support may be complemented by local or private sources of funding, marking a significant benefit to developers like EVgo and incentivizing the continued widespread build-out of a more comprehensive national fast charging network.
As EVgo expected, preference of federal infrastructure funds will be toward build-out along highway corridors first, with requirements that chargers be at least 150 kW in capacity with at least four charging stalls per location. Those locations are meant to be no more than one mile off a highway in most cases. States must submit their fast charging infrastructure plans to the federal government by August 1st, with approvals of those plans expected by the end of September. While EVgo is looking forward to participating in NEVI once the program structures are finalized at the state level, our guidance for 2022 does not incorporate any financial benefits that might arise from these incentives. Over the coming quarters, we will provide investors with updates on state-level implementation, the role EVgo is playing in different geographies, and the financial upshot for the company.
As we look back on the rapid evolution of the EV charging industry in 2021 and look ahead to what we expect will be even more substantial growth ahead, I thought it was timely to revisit EVgo's approach to the market. We've always had a driver and customer-centric focus, building chargers where we think they will help spur the adoption of EVs and where they will be used. The complement to that, of course, is providing solutions to the auto manufacturers and the site hosts that need EV charging infrastructure built to accommodate their own customers' needs. As a leader in the sector, EVgo has a finely honed methodology for determining where and when to build, own, and operate fast charging infrastructure to meet our investment hurdles and unlock long-term cash flow and profitability for our investors. Hence, EVgo's historical focus on owning assets in high-traffic metropolitan areas.
With interest in the EV market expanding to lower traffic, rural geographies, and corridors, EVgo is receiving requests to parlay our world-class experience in building stations and operating the most expansive and reliable public network in America to new geographies in which we would prefer to be the services provider rather than the asset owner. Fueling along interstates is an example of such an opportunity. We expect growth in this area to be bolstered by the passage of the infrastructure legislation, whose policy objectives include national charging infrastructure ubiquity. With this in mind, EVgo is excited to announce the formalization of our white- label services provided for years to partners like Kaiser Permanente, Green Mountain Power, and Salt River Project in the form of a new offering under the banner EVgo eXtend.
EVgo eXtend partners will leverage all the end-to-end benefits of EVgo's decade plus of planning, building, operating, and maintaining the nation's most reliable charging network, while the partners themselves purchase and then retain ownership of the charging assets. Formalization of EVgo eXtend into our solution suite puts customers and drivers first, unlocks another avenue for value creation and near-term growth upside, expands EVgo's geographic reach and potential partners, and complements efforts in the rest of our business that relate to fleet, software, and scaling efficiencies.
EVgo eXtend leverages our core competencies to expand our network footprint beyond sites that currently meet our underwriting hurdles for asset ownership, creates another way to grow recurring revenue, and mitigates risk associated with sites that are likely to have low utilization in the intermediate term. We're working on several exciting potential EVgo eXtend partnerships that will provide upside to our overall growth in the years to come. We're hopeful that we will be able to communicate more concretely about these efforts soon. Please stay tuned for updates. As mentioned at the outset, you may have seen recent announcements from EVgo on new partnerships with two major auto OEMs, Subaru and Toyota. With Subaru, EVgo was proud to become the preferred charging partner for their first electric vehicle, the Solterra EV, which is expected to become available in the U.S. this summer.
EVgo's business deal with Toyota provides for one year of unlimited charging on EVgo's network for buyers of or lessees of Toyota's first widely available electric offering, the bZ4X, which Toyota anticipates will be available later this year. This marks Toyota's first move in significant plans to become fully electric, and EVgo is delighted to have been selected as their fast charging partner. As I noted earlier, with Toyota and Subaru, along with existing partnerships with other OEMs, EVgo now has charging relationships with auto manufacturers that together represent over 40% of annual auto sales in the U.S. This provides clear evidence of the success EVgo has had in building and operating America's most robust fast charging network over the last dozen years. One of the many reasons EVgo is able to attract and retain high-quality partnerships is a commitment to technology-enabled innovation across the company.
One of these innovations is EVgo Inside, which is a suite of software and APIs that helps EVgo partners manage the customer experience process from enrollment to charging to billing. We recently released an updated mobile app that showcases both a sophisticated and a friendly design that welcomes drivers to the EVgo charging experience. Our EVgo Reservations and EVgo Advantage software products have broadened their reach into new locations during 2021, and EVgo's PlugShare surpassed 2 million registered users. Electrification activity in the fleet segment has rapidly expanded during the last 12 months, with EVgo's current fleet clients like Uber, Lyft, and two leading AV companies ramping their EV deployments and dozens of new fleet operators placing their first orders for EVs. These newcomers to electrification are beginning to engage in charging infrastructure planning as they await arrival of their EVs.
EVgo's fleet team is at work helping fleets craft infrastructure programs that will meet their needs through our EVgo Optima, EVgold, and EVgo Inside solutions. We look forward to sharing updates with you in the coming quarters. Before I turn the call over to Olga, I want to underscore the EVgo investment opportunity in the context of the growing EV ecosystem as a whole. As we shared, EVgo is a pure-play EV charging company with a special focus on DC fast charging and a history of executing and operating at a superior level, with uptimes in the high 90% range for our chargers historically and with over a decade of delivering on our promises to site hosts and drivers. We are a pioneer with a first-mover advantage in this sector, including being powered by 100% renewable energy.
Our relentless focus on innovation in technology, products, and solutions has provided us with an edge in designing and engineering charging locations in a way that attracts partners and drivers. We have a world-class executive leadership team with deep expertise in clean energy and that has a clear vision for leading an electrified future. The superstar employees across every function at EVgo are not only committed to excellence in delivery of EVgo charging services, but to the larger mission of a decarbonized transportation future. EVgo has ESG in our DNA. EVgo's experience and track record of execution are durable advantages in a sector with tremendous growth opportunities. We've done this all with a keen focus on financial discipline, long-term margin potential, risk mitigation, and underwriting that prioritizes profitability and the prudent allocation of investor capital.
As Olga will share, even in these early stages, we have realized positive results of this discipline, with growth in both customers and throughput, driving cash flows and providing concrete evidence of what the future will bring across the EVgo platform as EV adoption continues. We are more excited than ever about the immense opportunity in this space and EVgo's position in the market as EV adoption is set for takeoff. We expect a lot of positive inflection points in 2022, with increasing driver demand, OEMs introducing new vehicles, and the implementation of supportive policy. We would also point to the long term and remind everyone that we're in the early innings of a major sectoral transformation. The electrification of the multi-trillion dollar transportation sector is just getting started.
EVgo is poised to be a key player in this transformation, and we couldn't be feeling better about the future. With that, I will turn it over to Olga to discuss some of our financial and operational highlights. Olga?
Thanks, Cathy. I will start with some key operational highlights and review of our financial performance in the fourth quarter and full year of 2021. As Cathy noted, network throughput of 26.4 GWh exhibited material growth in 2021. With a 68% year-over-year increase and a 95% increase in the fourth quarter of 2021 versus the fourth quarter of 2020. Throughput for the year exceeded our guidance range of 24 GWh-26 GWh provided during our third quarter earnings call. Our active engineering and construction development pipeline exhibited big gains during the year, ending 2021 with over 3,100 stalls. Our active engineering and construction development pipeline was at 2,500 at the end of third quarter, exhibiting a 26% quarter-over-quarter sequential increase.
We ended 2021 with 340,000 customer accounts on our network, which represents 47% growth year-over-year. Overall, over 109,000 customer accounts were added to EVgo's network in 2021, which represented roughly 80% of non-Tesla EV sales. We also continue to attract Tesla drivers. Our data suggests that Tesla drivers continued to comprise about 15% of our new customer accounts, and that Tesla drivers represented approximately 6% of total EVgo retail charging throughput at the end of 2021. Revenue in the fourth quarter of 2021 increased 70% versus the fourth quarter of last year and 15% quarter-over-quarter sequentially, as the combination of EV adoption and EVgo's business development efforts drove high activity in both retail and fleet segments.
Adjusted gross margin hit new highs of 28% during the fourth quarter due to high usage and growth in high- margin data-driven ancillary services business lines. Turning now to the full-year results. Revenue increased 52% year-over-year to $22.2 million, above the upper end of our guidance range of $20 million-$22 million provided during the third quarter earnings call. This was primarily driven by an 88% increase in retail charging revenue year-over-year and an 84% increase in ancillary revenue, including the addition of Recargo revenue. Adjusted gross margin for the full year increased from 3% in 2020 to 23% in 2021 as we continue to scale the business driven by greater contribution from high margin data-driven ancillary revenues like Recargo and network throughput growth that allow to exercise operational leverage.
Finally, adjusted EBITDA was - $51.4 million for the year, which was ahead of our guidance of negative $54 million-$58 million, as revenue was stronger and G&A expenses grew at a slower rate than anticipated. A note on stall deployments for the full year. We finished 2021 with 1,676 operational stalls and 1,903 stalls either operational or under construction. Both of these figures were in line with our guidance provided on the third quarter call. I would like to spend a few minutes talking about EVgo's business model and key profitability drivers. The EVgo business model is centered at deploying charging infrastructure that generates double-digit unlevered pre-tax IRRs. I would like to walk you through our deployment criteria and station economics.
EVgo employs both short-term and long-term demand models to determine expected usage for every project we develop. Our short-term model, which predicts demand down to the census block or about one-tenth the size of a ZIP code, has been highly accurate in its predictive capabilities. Our longer-term model overlays short-term forecasts against adoption trends in the marketplace for EVs and fast charging. For every project we underwrite, we develop a financial model using this utilization forecast, revenue per kWh evolution, regulatory credit pricing evolution, if applicable, non-energy costs and energy costs per the existing tariff. Note, we do not assume improvements in those energy costs unless new tariffs have been approved by utilities.
I would like to highlight that modeled non-energy costs for every project are quite encompassing and include maintenance, warranties, rent, property taxes, connectivity charges, call center costs, payment fees, and the portion of asset management and customer operations team salaries. CapEx estimates are provided by EVgo's engineering team based on contracts with vendors and specific project design. Estimates only include CapEx funding support, such as governmental grants or OEM offsets, if it is available to us at this specific location. Finally, we continue to model no residual value in our underwriting process. A practice we view as suitably conservative, but also likely to present upside opportunity for us as the market develops.
With respect to stations and operations, we continue to evaluate network financial performance on a cash flow basis by market, which is calculated as charging and regulatory credits revenue minus energy and non-energy costs, using the same cost categories as the ones we use during the underwriting process. California is the most advanced EV market in the U.S. It has attractive electricity costs, LCFS and FCI credit revenue opportunities, favorable fleet dynamics, and the highest EV penetration rate in the country. EVgo's California charging network already generates positive cash flows today. As an illustrative case study, I would like to highlight the specific performance of the San Francisco metro market within California. San Francisco EV adoption rate is about 3%, among the highest in the United States.
At year-end 2021, EVgo operated 292 stalls in the area, resulting in 8.4% utilization rate, generating 1.9 million kWh of throughput in the fourth quarter of 2021. The San Francisco charging network generates 43% cash flow margin for EVgo, driven by solid utilization levels and attractive energy cost environment, LCFS add-ons and dedicated fleet stall take-or-pay contracts. These margins and cash flow generation ability will increase with further EV adoption. San Francisco is far from the only metro market demonstrating such results. Other metro areas in California, such as Los Angeles, showed similar results, and we're seeing comparable profitability trends in markets outside of California as well. I can call attention to Portland, Oregon and Phoenix, Arizona as two more examples of metro markets where EVgo portfolios are generating positive cash flows.
This is in markets that have lower EV penetration than California and do not have the advantage of meaningful regulatory credit revenue. The rising tide of EV adoption continues to improve performance in these markets and many other across the country. EVgo's rigorous investment process and site selection are bearing fruit across a number of key markets already today, even when EV penetration remains very low, about 0.5% nationally, which demonstrates the strength of our business model and the attractive upside potential. EVgo's overall path to profitability is closely tied to EV adoption. We would like to illustrate what could happen to EVgo revenue and EBITDA generation and how EVgo is positioned to profitably scale when EV adoption increases from 0.5% today to 5%, 10%, and 15% in the future, noting these estimates still represent the EV market in its infancy.
At 5% EV adoption, we estimate EVgo revenue of between $1.9 billion and $2.1 billion, with corresponding adjusted EBITDA of $600 million-$800 million, representing a 30%-35% margin. As EV adoption increases to 10%, we expect revenue to reach $3.2 billion-$3.4 billion with adjusted EBITDA of $1.1 billion-$1.3 billion, representing adjusted EBITDA margins of 35%-40%. At 15%, we estimate revenue of between $4.8 billion and $5 billion with adjusted EBITDA of $1.7 billion-$2 billion with 35%-40% margins. EBITDA margin improvements are expected to be achieved by operational and SG&A leverage. EVgo expects to be profitable on an adjusted EBITDA basis at roughly 2.5% EV adoption rate. From there, the upside compounds.
In the near term, we're introducing 2022 guidance based on our current expectations for the full year. There are a number of factors that will impact our results. However, the most salient of which is EV adoption. Supply chain and other global economic and political challenges may present a short-term obstacle for OEMs in getting new models on the road. At the same time, we will continue to strategically invest in the massive midterm and long-term growth trends. As we invest, we will prioritize profitable growth with a focus on expanding margins over time. For the full year 2022, we expect to deliver network throughput of 50-60 GWh, revenue $48 million-$55 million, adjusted EBITDA of negtaive $75 million-$85 million, and total DC fast charging stalls in operation or under construction at year-end 2022 of 3,000-3,300 stalls.
Both revenue and network throughput guidance represent a more than doubling of comparable figures to 2021 results.
The drivers for Adjusted EBITDA reflect increased investments in technology and personnel to respond to expanding market opportunities and encapsulate our expectations for LCFS pricing and public company expenses. Finally, total stalls in operation or under construction reflects the advancements we're making in the size of the pipeline and the success in reducing the time in development, both of which are driven in part by the technology and personnel investments I just referenced. We're seeing a lot of progress and enthusiasm in the business with a number of strategic commercial partnerships in various stages of development. We believe that EVgo has a substantial growth runway over the next decade and beyond.
Assuming electric vehicles in operation grow at 35%-40% nine-year CAGR, as many forecasts agree on, we're looking at an 80%-85% CAGR for network throughput, 70%-75% CAGR for revenue, and 40%-45% CAGR for DC charging stalls. Given the strong tailwinds and significant industry momentum Cathy discussed earlier, we see a massive opportunity ahead and believe that EVgo is well-positioned to capitalize on it. Thank you for your time this morning. I would like to turn it over to the operator for questions.
Thank you. At this time, we will be conducting a question-and-answer session. If you would like to ask a question, please press star one on your telephone keypad. A confirmation tone will indicate your line is in the question queue. You may press star two if you would like to remove your question from the queue. For participants using speaker equipment, it may be necessary to pick up your handset before pressing the star keys. Also, in the interest of time, we do ask that each person in the queue to only limit themselves to only one question. One moment please while we poll for questions. Our first question comes from the line of Gabe Daoud with Cowen. Please proceed with your question.
Hey, good morning, everyone. Thanks, Cathy and Olga, for all the prepared remarks. Super helpful. Can we maybe start with slides 17 and 18? Maybe, Olga, give us a little more meat on the bone, so to speak. Like, if I'm thinking about long- term, the operating leverage here. What kind of underpins some of these assumptions? If you could just talk to utilization or stalls in the ground, that'd be helpful. Then also, to what extent does LCFS credits play into slide 17? Like, what percentage of that San Francisco cash flow comes from LCFS credits?
Hi, Gabe. Thanks for the question. 17, just to kind of clarify first, page 17, that's an actual number, right? There are no assumptions which are going into that. Those are the numbers we're observing. LCFS is, of course, an important part of our cash flow, but even if you remove LCFS cash flows from San Francisco, you'd still see a positive cash flow margin. I wouldn't disclose the exact number. I would like not to disclose the exact number, but I will assure you that remains positive in the San Francisco market. On kind of like what drives performance of San Francisco market today, first of all, it's the attractive energy costs. It's the tariff we have in PG&E is quite attractive, and that's what you observe here in the cash flow margin.
We have quite a substantial presence of dedicated fleet take or pay contracts, which is baked into this number. That plays into this. The third and most important is one of the highest EV adoption rates in the country. As you could see, it's 3%, and that bakes into pretty decent utilization of 8.5%. That's a utilization we deem decent as of today with the current adoption levels. We of course expect that the definition of decency will change over time, but for today's standard, that's pretty good. When we talk about page 18, there's a lot of assumptions playing into here. One of them you asked about the stalls.
We're not changing our overall target, which we manifested during our SPAC process of 16,000 stalls by 2027, and that's roughly what we're assuming, underpinning this various forecast. Again, we wouldn't probably disclose exactly what it will be, 5%, 10% or 15%. But when we run our forecast, we make sure that the CapEx investments and amount of stalls we're deploying to support the EBITDA and revenue generation makes sense and fairly prudent and conservative.
Yeah, if I could just jump in and add a little bit, Gabe. I love the reason we included our San Francisco as a market spotlight is that as we all know, California is an early bellwether to what happens in many things and in particular electrification. California has more EVs than the rest of the country, et cetera. Early adopter. California's been an early adopter in autonomous vehicles. California's been an early adopter in rideshare. All of those macro trends are going to spread across the country. So when we take a good look at our business model, we look first to California. Is it working in California? It's working in San Francisco, it's working in L.A.
What's really interesting is that, as Olga points out, it's also working very, very well even in the next stage of markets, which are like Portland and Phoenix. We just feel confident that we're capitalizing on investing in charging assets in a way that's going to ride the wave of electrification of transportation across America.
Awesome. That's really helpful. This is just a follow-up, I guess, just on this new business line, Cathy, Extend. Could you talk a little bit about maybe the economics there and are any stalls that are in queue for this year under this business model? Just how do we think about balancing that long-term potential that you highlighted on slide 18 versus the Extend business model?
What the EVgo eXtend is is an end for us. It's like we are really a market leader in siting, building, owning, operating. We essentially do the EVgo eXtend white label with a few customers now. The interest that we're seeing, particularly in corridors, interest in building in corridors grows, is that those corridors don't tend to meet our traditional hurdle rates to own the assets. However, there's a wonderful way for us to participate in that extension of our network through EVgo eXtend by providing the network planning, siting, construction, and then an O&M that comes with having those locations be part of our network that's accretive.
We are so excited to tell you about what we've got cooking in the oven as soon as it comes out of the oven, so stay tuned. It's a really, really exciting addition to EVgo's solution set.
Awesome. Thanks, Cathy.
Again, as a reminder, we do limit everyone to one question only. Our next question comes from the line of Maheep Mandloi with Credit Suisse. Please proceed with your question.
Hey. Hi. Yeah, Maheep Mandloi here from Credit Suisse. Thanks for taking questions and congratulations on the quarter. Olga, maybe a question for you. If you could just kind of break down the guidance for us so then we understand the revenue guidance message a little bit was driven by the rideshare recovery slightly weaker than expected. But if you could just talk about like on the gross margin and operating expenses, are you seeing any changes versus what the expectations were going into the year previously, especially trying to understand the impact of any rising electric bills later this year due to higher energy prices. Secondly, like, just wanted to touch base on EV charging hardware availability. Some of your peers have been talking about delays on that.
Any color on that would be appreciated. Thanks.
Sure. On energy costs, just to remind everybody that we are not trading wholesale power, and we're not exposed to short-term volatilities in power. We're a C&I customer of utilities. On a short term, on a short horizon, we know exactly what our energy costs will be. Now, obviously, the macro environment is as such that the power prices are rising, then utilities will probably start passing them on us, but we'll know in advance, and that doesn't happen overnight. We don't foresee that specifically we as EVgo will feel the effect of rising energy costs in 2022. On a gross margin, expect it to be where it is or improving with an improvement in throughput. Our gross margin is a reflection of a leveraging of fixed and operational fixed costs.
That's why you saw it improving. In addition, the growth of our high-margin, data-driven ancillary services. Both of those trends are expected to continue to be favorable next year. You'll see margin slightly better or at the same level. We're not guiding to gross margin, so I won't disclose specific expectations, but that's some light I can give to you. Then on hardware, we're obviously no exception to anybody else. We're extremely focused on securing hardware supply and managing our supply chain. As of now, all of our vendors have expressed confidence that they would be able to deliver the equipment we need this year at the pre-agreed price.
We have certain contractual agreements which give us, again, quite a decent confidence that that will be the case. I emphasized it in multiple conversations with investors before, and I'll emphasize again, our main concern regarding supply chain for this year is the ability for OEMs to manufacture and get access to various raw materials and components and get cars to American roads. That's, I think, where our main concern is centered around. That's outside of our control, but we're cheering for everybody in the market to deliver cars because again, as we emphasized multiple times through our script, our business is tied to the adoption. More EVs, more throughput, more revenue for us.
Gotcha. No, thanks. I'll jump back in the queue here.
Thank you.
Our next question comes from the line of Craig Irwin with Roth Capital. Please proceed with your question.
Good morning, thanks for taking my questions. I'm quite curious about this EVgo eXtend model. You know, it seems your more recent implementations skew towards using equipment from two vendors. You know, one of them is used by a number of other fast charging network operators, but the other happens to be the world's largest power supply producer and well known as a low cost, high- quality producer with very little representation in North America.
Do you expect to maybe have some sort of an alliance or strategic agreement that would allow you, assured supply or, a different type of access for this equipment, given that it looks like you might be blazing some trails for them where they've traditionally not had some, they've not been very good at marketing globally outside of, you know, the monster EMS companies and very large tech companies?
Yeah. Well, Craig, thanks for the question. On the hardware supply, as I think we've talked about before, our engineering team has an extremely rigorous process for qualifying any hardware that we put into the field, that we put onto our network. That'll be true for the EVgo eXtend customers as well as the assets that we retain ownership of. At the moment we've got two preferred vendors for our fast charging equipment that are capable of supplying 350 kW chargers, which is our standard ultrafast configuration now. We have a couple of other vendors that we've used in the past, but the team is continuing to qualify others that are capable. Again, the
Our exacting specifications for ultrafast, frankly, the vendors had to catch up to what we wanted and to be able to do power sharing and power routing. Our team is continuing to look at suppliers that will be able to meet those exacting standards that are essentially what we expect and what drivers will expect and what OEMs expect, which is the ability to ultrafast charge reliably. We wouldn't rule out any special sort of alliances with vendors in the future, but there's nothing more I can tell you at this point.
Okay. Then just as a follow-up, siting of chargers can often be challenging for local site capacity for electricity, right? A lot of conversation out there about co-implementing with batteries, with energy storage. Can you update us where you stand on this? Do you see this as strategically important over the next couple of years? Is the format that you're using the format of choice and what you expect to pursue?
Well, we have probably a dozen stations in California that have on-site batteries. We put them in years ago, and that was again a good economic decision to avoid punitive demand charges. We are quite open to it, frankly. Wherever it will pencil economically, it makes good sense. In some cases, the utilities will be excited about it. As utilities modernize and go to more distributed energy sources and two-way power flows, I think there's gonna be more interest in that. The very practical question for us is, does the location have the footprint to have on-site storage?
What we're, you know, pretty excited about some of our larger projects under development, you know, mega hubs, giga hubs, charging hubs, where there will be room in a parking lot or in the location for on-site storage. Again, it all has to pencil for us. Our financial discipline is unwavering. It's got to pencil to double-digit returns. If it makes financial sense, we're open to it. There's a lot of different ways, a lot of different people that can come to the party to help that pencil for us. Yeah, we've got the team that knows how to do it, and it's a possibility for the future.
Excellent. Thanks for taking my questions.
Our next question comes from the line of Ryan Greenwald with Bank of America. Please proceed with your question.
Hey, good morning, everyone. Perhaps starting with 2022 guidance, can we just help reconcile a bit in terms of the throughput being down 20% and significant price deflation to LCFS credits, more modest 5% decrease to revenue. Obviously, you have the full year of contribution from Recargo, but can you just talk a bit about other key offsets there?
Sure. First and foremost, on the network throughput, the main difference. We haven't provided the formal guidance before just to send to everybody. From my understanding, you either reference in the SPAC deck or your own forecast. The delta here is the delay in the rideshare recovery. We continue with the good news that we start to observe the rebound of rideshare in general as an industry. What we now are seeing is that there is not enough cars for all the rideshare operators to get and electrify their fleets, and that is delayed, and that's a fact of a post-COVID hangover and supply chain challenges. That's the main driver of why the network throughput is probably below somebody's or everybody's expectation.
On the revenue side, you're absolutely right. LCFS is below what we all thought even a few months ago, and that is baked in to a certain extent in our forecast. We're observing the situation, of course, because the situation is dynamic. Some of the offsets are our take-or-pay fleet contracts, which we see quite a strong pipeline on and making certain assumptions on when those projects will hit operations. Those are independent of throughput. Just to remind everybody, take-or-pay fleet dedicated contracts. It's a fixed amount of dollars paid to us a month independent of the throughput, and we have quite a strong view on that for this year. On an eXtend side, as Cathy mentioned, we have some income.
We haven't included a full effect of that here because most of what's being baked in will manifest itself in 2023 and beyond. There are certain modest inclusions in the second half of the year where we might see those effects, and they have been included here.
Great. Thank you. What is the embedded LCFS credit pricing assumption that you guys are assuming now in 2022? How are you thinking about timing of cash flow and collection if these levels are sustained?
We are assuming $150 for the full year.
On cash flow inflection, how would that kind of impact how you guys are thinking about things?
I'm not sure I fully understand your question. On the cash flow inflection?
In terms of which year you would expect to inflect positive?
We wouldn't provide that guidance, but I'd like to reiterate some of the messages I was given in the script. We expect to be adjusted EBITDA positive at a moment in time when EV adoption is going to be around 2.5%. It's 0.5% now. Again, our business is very much tied to EV adoption levels. If that 2.5% will hit earlier, then we'll be EBITDA positive earlier or later. That's how we think about our business, but we're not giving a specific year guidance for that.
Okay, great. Appreciate it. Thanks for the time.
Our next question comes from the line of Vikram Bagri with Needham. Please proceed with your question.
Good morning, everyone. I have a multi-part question on California study. You show that EV to EVSE ratio is pretty high, and yet the utilization is under 9%. How do you see that situation evolving over time with either more EVSEs being installed? Do you see utilization coming down, or do you see utilization going higher and EV on EVSE ratio staying where it is? And then, I think, also you mentioned 6% of throughput is represented by Tesla chargers. Could you compare that to what percentage of connectors are Tesla connectors? I believe that percentage is higher. How do you plan to sort of close that gap between the throughput and the percentage of connectors allocated to Tesla?
The third question I had was, although you mentioned in your remarks that you pass on the higher cost of electricity, because you get a heads-up from the utilities months in advance, you've had two price increases in California and multiple across the country so far this year. What percentage of the revenue per kW increase year on year in 2022 is just being driven by higher energy costs that you're passing on to the customers?
Yeah. For the first one, we do expect utilization to go up over time. Let me kind of go back to the basics of DC charging, utilization and DC charging business. The utilization on DC charging infrastructure is not only driven by EV-to-stall ratio, it also is driven by MUD density and what percentage of charging needs of this specific population is being met by DC. It's gonna be very different in San Francisco versus Santa Monica versus a place in the country where people live in single homes.
Yeah, just MUD density is multi-unit.
Multi-
Apartments.
Apartments. Sorry, it's our internal jargon, and I kind of assume everybody knows. It's how many people live in apartments versus how many people live in single-family homes. That's a very important driver because if you have a charger at home, bear no illusions about it and the data confirms it, you will use your charger at home. Another very important factor here is electrification of fleets. Right now, San Francisco is quite an advanced market regarding fleets, but it's still not at its final end game point and with expectation of more electrification of rideshare. Just as a reminder, we discussed this during our previous earnings call. An average commuter drives 11,000 miles a year.
An average rideshare driver drives 40,000-60,000 miles a year, and on top of it uses DC charging for 70%-75% of their charging needs. That's a massive contribution to utilization. With that in mind, that kind of like just thinking about utilization as a function of EV to stall ratio for the years to come is not fully correct. We do think that utilization for the network in 5-6 years on average will probably be around 18%. That's our best guess as of now, and that's how we run our models. We think it's fairly conservative as well, but we expect utilization to go up over time for the network. That's answering your first question.
The second question about the Tesla, I'm not sure I follow what the question is about. Cathy, if you-
Are you asking, Vik, to what extent the Tesla connectors on our EVgo chargers are reflecting that uptick of Tesla usage on our network? I don't quite understand your question either.
I was trying to understand what percentage of your total connectors over your network are Tesla connectors. I believe that percentage is higher. Maybe, you know, 10% or 15% of your connectors are Tesla connectors, but the throughput allocated to Tesla vehicles is only 6%. I was wondering, like, is it a factor of, you know, pricing not being competitive or Tesla drivers preferring, Tesla connectors only? How do you sort of like close that gap where you're installing a slightly higher percentage of connectors are allocated to Tesla, but the throughput percentage allocated to Teslas you're seeing is lower?
I think I see what you say. We're ramping up Tesla connectors, and we're ramping them up throughout 2022. That's just extreme beginning of Tesla usage on our network. It's 6% of total retail usage across the country. We have geographies where it's much higher, and it goes to double digits %, and the ratio gets reversed. That usage is very much dependent on what we're seeing from early data on availability. Geography by geography, you'll see very different ratios, very different percentages. 6% is a blended number, but that is mostly driven by lack of Tesla infrastructure in the specific geographies. For those geographies where the ratio of Tesla EVs versus Tesla Superchargers is skewed and there is not enough infrastructure. We see very high usage of Tesla on our network.
For the places where it's reversed and there's abundance of infrastructure, there's not that many, but the, they exist. We don't see such high percentages because of course, Tesla drivers will use a Tesla Supercharger before they come to us. That's okay, that's what we planned for, and that's how our business model works. That 6% number, which is very early inning, and as I also mentioned in my script, that 15% of all new customers which sign up with EVgo are Tesla, which shows that that 6% is positioned to grow further. We're quite happy about those results. Just to re-interpret, it's a good news, it's not bad news.
I think there was another question about electricity pricing. Like our pricing and electricity pricing. Do you wanna talk a little bit about that?
Right. Conceptually, we are not, we're not in the business of determining retail prices as a pure spread. It's not necessarily that we are going to pass on consumers every single increase of tariffs, because we look at it from a network perspective. In certain places, yes, you get indexation or you get the inflation or some tariff adjustments up. In certain other places with the great efforts of our market development team, we're getting access to much better tariffs and much better per kW hour energy costs. On top of it, with the increasing utilization or increasing throughput, demand charges, which still exist in our network, get amortized, which again translates into lower per kW hour energy cost. You have all these different multiple factors and vectors of events happening on the network.
We again, we're not passing every single cent back on a consumer. We're going back and estimating the whole network or maybe like a market by market and trying to see if that still makes sense, if economics still works.
The other thing I would add is that what you've seen in California, Vik, is that we introduced first we went to kWh pricing from per-minute pricing. Second, we introduced time-of-use pricing at the behest of the utilities and the California Public Utilities Commission. We've been watching what different types of consumer responses, driver responses there have been to cheaper early bird pricing, higher on-peak pricing. What we do, and I think I might have said this before, we have a software backbone that will allow us to do customized pricing based on location, and we also introduced location-based pricing. Our pricing is not inextricably linked to the electricity cost.
There are a multitude of attributes that we use to determine what pricing will make the most sense, that will deliver value to drivers and will maximize income to us.
Understood. Thank you.
Our next question comes from the line of Bill Peterson with J.P. Morgan. Please proceed with your question.
Hi, this is Mahima calling in for Bill, and thanks so much for taking our question. So just really quickly, have you seen any impacts from any permitting delays? If so, has it been prevalent in any particular geographies? Then maybe could you give us the latest timing from order to up and running, so essentially from site selection to installation?
Yeah. You know I love this question. This is, like, my favorite topic is creating the flywheel so that we can deploy more fast chargers more quickly. I will start off with, you know, our pipeline continued to grow. Site hosts continue to be really excited about having charging infrastructure on their parking lots. Still takes us 4-8 weeks to actually start digging and then get the station built. What we're seeing is, again, last year I talked about going from 18 months on average down to 6 months. We are still nowhere close to 6 months. That's still my dream, but we've got a long way to go.
As we go into new jurisdictions, it is often the first time a local government has, like, had to approve a charging station. The variability around that timing, it can be as short as one week, and it can be as long as 12 months for the local government permit, and I kid you not. Similarly, with utilities approving designs and getting easements with the landlords, again, it can be as quick probably as 4-6 weeks and as long as 12 months. The final energization process that the utilities have to do for inspection, again, that can be, like, next day or that can be probably 6-8 weeks.
We had a whole bunch of stalls done at the end of 2021, like dozens that were completely ready for drivers except the utility had to come along and do the final inspection. We've got Connect the Watts that we're pushing on, like, to continue to share best practice. The more activity in the sector, the quicker we assume it'll go. It's like early days of solar. But it is something that we're continuing to work on and like, as I say, making progress, but I think I can't give you a number because variability is still, we've got super fast players and then we've got super slow-mo. I don't know, the latest is probably on the distribution around that, but it's a pretty wide distribution.
Hope that helps.
Yes. Thanks so much for the color.
Our next question comes from the line of Andres Sheppard with Cantor Fitzgerald. Please proceed with your question.
Hey, guys. Thanks for taking my question. Congrats on the quarter and thanks again for running a few minutes over and taking all of our questions. Maybe just to quickly follow up from the last question there, are you able to give us any sort of breakdown in terms of how quickly you can convert those, you know, over 3,000 stalls that are in the pipeline into operational? Maybe in addition to that, any plans of expanding, you know, abroad? You know, I know some of your peers have been increasing their footprint in Europe, for example. I'm just wondering if that's something that's being thought of. Thanks again.
Yeah. On the timing, look, I think that, like, what we're now doing is sort of counting on at least 12 months from idea to energization, right? Not wishing for 6 months. We're counting on 12 months, and we're working really hard on that. Again, you know, that's what we're doing right now, like, those 3,000 - 3,300. Those are gonna get energized. You know, there's gonna be dogs that take longer and then there's gonna be super quickie ones. Generally speaking, those are gonna be sites that are gonna go. The 3,000- 3,300 have been in planning for a while that are gonna go live.
We're building the pipeline for even bigger numbers for 2023, 2024, 2025, right? That's kind of what our site host development team is working on. That's just sort of learning and, like, we'll be delighted if it starts to go faster. Like, we'll be delighted. On the overseas planning, we'll look, we've got our hands full. We're really busy. We're actively doing all kinds of things in the United States. With that said, we'll be opportunistic. If there's an opportunity to naturally sort of extend our expertise, our skill, and our returns, you know, bring in, grow the business overseas, we wouldn't be closed to it, but it's not something that we're actively pursuing at this point.
Got it. Very helpful. Thanks again and again congrats on the quarter.
Appreciate it. Thank you.
Ladies and gentlemen, we have reached the end of the question- and- answer session, and also this concludes today's conference as well. You may disconnect your lines at this time. Thank you for your participation.
