As a reminder, this conference is being recorded. I would now like to turn the I would now like to
turn the
conference over to your
host, Mr.
Patrick Joepin with Investor Relations. Please go ahead.
Thank you, operator, and thank you to those on the call for joining us today. Before we begin, please note that certain remarks we will make on this conference call constitute forward looking statements. Although we believe these statements reflect our best judgment based on factors currently known to us, actual results may differ materially and adversely. Please refer to the company's filings with the SEC for a more inclusive discussion of risks and other factors that may cause our actual results to differ from projections made in any forward looking statements. Please also note these statements are being made as of today, and we disclaim any obligation to update or revise them.
On the call today are Lynn Jurich, Sunrun's Co Founder and CEO Bob Komen, Sunrun's CFO and Ed Fenster, Sunrun's Co Founder and Executive Chairman. The presentation today will use slides, which are available on our website at investors. Sunrun.com. And now let me turn the call over to Lynn.
Thanks, Patrick. We are pleased to share Sunrun's 3rd quarter results and progress against our strategic priorities. We are on track to deliver cash generation of $100,000,000 this year, which represents about 60% year over year growth. We expect to lead the industry again by adding well over 50,000 in 2019 and growing our customer base over 20%, now approaching 300,000. The near term customer growth is lower than we were expecting due to labor shortages in both installation and our sales force.
However, the strength of orders and the increasing value proposition from batteries and forced blackouts makes us confident in a 15% to 20% long term growth rate in new customers with continued strong cash generation. In the quarter, we added 14,200 customers, representing just over 107 megawatts of deployments, a 7% year over year increase and within our guidance range. We generated $22,000,000 in cash and have achieved record low capital costs. Consumer interest remains strong, and we are actively working to increase our capacity to meet this demand. We expect to grow 9% quarter over quarter in Q4.
Households across the country are facing unreliable and increasingly expensive electricity service. Forced blackouts in California are the new normal with PG and E saying they will last a decade. Investing in inefficient centralized infrastructure and forcing blackout to lower the risk that transmission lines and equipment start fires is not sustainable. Sunrun offers home owners the ability to generate and store their own energy with our Brightbox service and we are networking those together to provide services to the entire system through our grid services efforts. The decentralized system we're helping build is the best way to achieve affordable, resilient power in a warming world.
100 of Sunrun customers in California were able to keep the lights on during multiple recent outages. The average customer affected lost power for 35 hours. Families facing these outages are eager for resiliency. In the Bay Area, the attachment rate of Brightbox nearly doubled to approximately 60% for new orders in October. The stories we heard are moving.
1 family lost power for 142 straight hours, nearly 6 straight days. With Brightbox, they were able to run critical loads like the refrigerator and lighting without interruption. While some sync backup generators are the only solution, they are far inferior. They are expensive, pollute, require constant refueling, which may not be possible with fuel stations also down, and are noisy and need maintenance. Brightbox can power a home's critical needs for about 12 hours through the night and can recharge when the sun shining, providing power through multi day outages.
Nationally, we have now installed more than 8,000 Brightbox systems. Attachment rate for Brightbox sales in our direct business was approximately 30% in California throughout Q3. And while we have only launched the service in 9 states thus far, we're approaching 15% attachment across all geographies. Overall demand continues to be strong. We are seeing approximately 15% to 20% growth in orders in Q3 and into Q4, which is consistent with our views on long term industry growth rates.
While demand is trending in line with our expectations, we are facing constraints in our ability to install and meet sales demand, exacerbated by a tight labor market. For example, in California, our largest market, which is seeing some of the strongest growth trends, unemployment rates are at record lows and construction labor is especially tight with all the rebuilding following the fires. We are actively working to fill over 600 positions in our installation and sales organization. Sunrun can be a preferred employer given the benefits and career mobility our national scale and growth provides. We believe our benefit packages along with the opportunities for career progression are among the best and can differentiate us from smaller localized solar companies.
I'm confident we can address the labor challenges over the next couple of quarters. We are focused on delivering strong financial returns. We are on track to generate $100,000,000 of cash flow this year, which represents growth of 60%. This is repeatable through continued growth in our customer base, resiliency offerings in California, further cost reductions and advanced grid service offerings combined with a strong financing environment. We are excited about 2020 and will share official guidance on our Q4 call early next year.
I'll now turn the call over to Bob to review Q3 performance and to discuss next quarter's guidance in more detail.
Thanks, Lynn. NPV in the Q3 was approximately $7,000 per customer or $0.90 per watt. Year to date, NPV is about $1.02 and unchanged from last year. NPV would have been higher and above $1 in the quarter had it not been for install flagging sales growth, particularly in high value markets like California. We expect NPV to be above $1 in Q4.
Project value was approximately $32,400 per customer or $4.18 per watt in Q3. As a reminder, project value is very sensitive to modest changes in geographic channel and tax equity fund mix. Turning now to creation costs on Slide 8. In Q3, total creation costs were approximately $25,400 per customer or $3.28 per watt, an improvement of $0.06 or 2% from last quarter. As with project value, creation cost can fluctuate quarter to quarter.
As a reminder, our cost stack is not directly comparable to those it appears because of our channel partner business. Blended installation cost per watt, which includes the cost of solar projects deployed by our channel partners as well as installation costs incurred for Sunrun built systems was $2.48 per watt, a 4% a $0.04 improvement from last quarter. Install costs for systems built by Sunrun improved by $0.16 or 8% year over year to $1.90 per watt. In Q3, our sales and marketing costs were $0.81 per watt, up $0.01 from Q2. Our total sales and marketing unit costs are calculated by dividing costs in the period by total megawatts deployed.
A higher mix of direct business results in higher reported sales and marketing cost per watt, but it also means there will be lower blended installation cost per watt over time due to the higher mix of Sunrun built systems at a lower cost per watt. In Q3, G and A costs were $0.25 per watt, an improvement of $0.03 from Q2. Finally, when we calculate creation costs, we subtract the GAAP gross margin contribution realized from our platform services. This includes our distribution, racking and lead generation businesses as well as solar systems we sell for cash or with a 3rd party loan. Our platform services gross margin was 0.26 dollars per watt in Q3, dollars 0.01 higher than last quarter.
In the Q3, we deployed 107 megawatts. Our cash and third party loan mix was 18% in Q3, in line with recent levels. We expect this mix to continue in the high teens. Turning now to our balance sheet. We ended the 3rd quarter with $373,000,000 in total cash.
Quarterly cash generation was 22,000,000 dollars We continue to expect cash generation of $100,000,000 in 20.19. We define cash generation as the change in our total cash less the change in recourse debt. Cash generation can fluctuate significantly due to the timing of project finance activities. As a reminder, our cash generation excludes strategic opportunities and ITC Safe Harbor related activities, which we will undertake. Ed will discuss our safe harboring plans in more detail later in the call.
We also want to share 2 corporate finance updates. First, we amended our working capital facility, our only recourse credit facility, to extend its maturity to April 2022 and to enhance its flexibility. Rate and size were unchanged. 2nd, our Board has authorized a 3 year up to $50,000,000 share repurchase program. As we continue to generate cash and now have an equity light Safe Harbor strategy in place, we view this program as another tool to create shareholder value.
Moving on to guidance on Slide 9. We expect to deploy between 115 and 118 megawatts in Q4. As our direct business represents a larger portion of our mix, more expenses are front loaded for increasing sales and deployment capacity. The dynamics of a tight labor market and these more front loaded expenses put pressure on NPV and cash generation. Despite this, given the strong financing environment, we still expect to generate $100,000,000 of cash in 2019.
We expect NPV per watt in Q4 to be above $1 and for 2019 to be near prior year levels. Now let me turn it over to Ed.
Thanks, Bob. We have lots of good news to share across all of our capital raising activities. Today, I plan to focus on our recent capital market activities, implied capital costs and our investment tax credit Safe Harbor strategy. I'll also review cash generation, net earning assets and capital runway. Low interest rates and strong finance execution continued to provide a strong tailwind for the company.
In October, we once again set new records for capital cost and advance rate with our $312,000,000 securitization of solar assets. We priced the senior notes at 3.63% with an 80% advance rate, demonstrating that the market and ratings agencies increasingly recognize both the high quality of residential solar assets as well as our industry leading performance. The depth of investors for senior and subordinated debt continues to increase significantly as well. October's transaction was similar in structure to the one we closed in December 2018. Comparing the 2 securitizations, however, this year, we achieved a yield that was 191 basis points lower, an advanced rate that was 8 percentage points higher, and a single A rather than A- credit rating.
In addition, we achieved a BB credit rating on an additional tranche of debt with a 95% cumulative advance rate at a 6% discount rate, setting the stage for us to raise more than 100% of contracted asset value from subordinated debt outside the ABS market in a transaction we expect to close during Q4. In addition, these facts lay bare that a 6% unlevered discount rate for our assets is now too high. To put our current labor constraints and growth trajectory in our Development business in context, if we measure customer values using a 5% discount rate rather than a 6% one, our net present value year to date would be approximately $0.25 a watt higher mark to market. Next, I would like to preview our investment tax credit safe harbor strategy. While we are planning for our business to thrive in a lower ITC environment, we're also availing ourselves the safe harbor provisions the IRS has codified to extend access to higher tax credit levels.
We expect to extend access to the 30 percent tax credit for about 500 megawatts of projects by incurring more than 5 percent of the cost of these projects in 2019. Because we expect to debt finance on a non recourse basis, the vast majority of these costs, we initially expect to carry about $25,000,000 in equity capital against this strategy. Note the actual cash amount of equity capital deployed at exactly December 31, 2019 may vary based on the exact timing of payments and capital draws. The credit facility we anticipate closing is a multiyear revolving facility. As such, we can elect to add equipment to it during future years to further safe harbor at 26% or 22% ITC levels.
We expect to benefit from at least a 22% investment tax credit through December 20 23 on our lease projects with the 10% permanent tax credit becoming relevant in 2024. This ability to extend access to higher tax credit levels exists only for residential solar systems that are subject to a PPA or lease or what we call Solar as a Service. Solar as a Service represents approximately 80% of our run rate business. Absent a change in law, next year and for all future years, Solar as a Service will therefore enjoy a substantial competitive advantage versus systems purchased with cash or a loan. This structural advantage in favor of Solar as a service will begin at 4% of cost next year, climb to about 26% of cost in 2022 and settle at 10% of cost in 2024 and for all subsequent years.
The perpetual 10% advantage for solar as a service is because it benefits from a 10% tax credit under permanent law, while homeowner purchase systems do not. We're also monitoring the environment in Washington and are pleased to report there is a growing coalition in support of extending renewable energy tax credits as the single highest impact actionable policy opportunity to combat climate change. However, especially with the wildcard of impeachment, handicapping the chance of passage in any specific moment in time is difficult. We're nevertheless increasingly optimistic for its eventual extension. Moving to Slide 10, net earning assets increased both year over year and quarter over quarter to $1,400,000,000 Net earning assets, measured at a 6% unlevered discount rate, is our way to describe the value of cash flows to Sunrun's shareholders after payments to finance counterparties.
Cash was $373,000,000 Total cash, less recourse debt, increased $106,000,000 year over year. Turning finally to our pipeline, our project debt and tax equity runway each extend into the Q4 of 2020. With that, I'll turn the call back over to Lynn.
Thanks, Ed. With that, let's open the line for questions, please.
Our first question is from the line of Brian Lee with Goldman Sachs. Please go ahead, sir.
Hey, everyone. Thanks for taking the questions. I guess first off maybe to provide a little bit of context around the labor issue and the sales funnel. I think last quarter you mentioned you were seeing above 20% bookings growth. Can you give us a sense of how much bookings growth you saw in the quarter this time around?
And then can you also comment on cycle times today if they've sort of moved outside of that 60 to 90 day target window? And then I had a follow-up.
Sure. So yes, Brian, the orders are at 15% to 20% for Q3 and we expect that to persist for Q4. So again, if you look over any multi quarter time horizon, we're sustaining those types of growth rates. And as we described last quarter, we fell behind after focusing on install efficiency, and it's proven to be difficult to catch up quickly in a market this tight and especially at our scale. So we have 600 open positions today.
So I think if you just again look at the cycle times on that, they are being pushed out. And the key there is you really want to communicate with your customers upfront with the right expectations and that really helps you mitigate any sort of concerns with that and that's how we're approaching it.
Okay. Well, just Lynn, maybe to clarify on that comment about pushing out, is it pushing out within that 60 to 90 day window? Are you inferring that you're actually sort of in some instances moving outside the 90 day
We some backlog will be built and pushed into Q1. So if you look at Q4, the growth rate from Q3 to Q4 is 9% quarter over quarter. So it's still strong growth, but you're going to see, still some backlog being able to be realized in Q1.
Okay, that's helpful. And then I guess that's kind of a segue into my second question and then I'll pass it on. So the labor issues, I think most people appreciate they're keeping you from hitting the deployment targets here for the year. But if we do look ahead into Q1, obviously, weather is something you can't control, but volumes are seasonally weaker. But you do have deployment capacity just based on the Q4 guidance here that would imply you can do I guess over 150 megawatts a quarter.
I would doubt most people are expecting it to be that strong into Q1. But your question is just trying to get a sense of how much of the labor issues are impacting you now because you're in a seasonally strong period of the year? And then maybe does that just naturally lessen into the early part of next year as things slow down seasonally and then you've ramped up some of this capacity, the sales funnel is strong. And so maybe the sales to install lag, you really do start to see it, kind of naturally helped by some seasonal slowness?
Yes. You characterized it well. We do expect to catch up within a couple of quarters, and that's a combination of actions we're taking, a lot of the actions you may suspect we're taking, which are around hiring recruiters inside and outside, making sure our compensation and retention packages are tight, making sure we're really marketing the employment brand and the career opportunities that we have. And so again, this issue came up last quarter and at our scale, it's hard to do it in a quarter. But with any reasonable period of time, we feel confident we can catch up.
The other thing that we are leveraging and we're also seeing a little tightness is just leveraging third party labor as well. So one of the advantages to our business model is we do have this They also are constrained in this market, as you can imagine, but it gives us a little bit more flex. So I think you characterized it well, and we think getting into Q1 will be in good shape.
Okay. Thanks a lot. Appreciate it.
And your next question is from the line of Michael Weinstein with Credit Suisse. Please go ahead.
Hi, guys.
Good afternoon. Hey, there.
Hey. So Ed, you mentioned 5% as a possible new legitimate discount rate based on the outcome of the ABS refinancings. I'm just wondering if you'd plan to actually deploy that in any future presentations at this point?
That's a great question, Michael. We are currently of the mind that we are less likely to actually mark to market the 6% discount rate. Certainly, if conditions change very materially, we may always revisit that. However, certainly, the experienced capital costs in the market are significantly below 6%. And I think we're also focused principally on generating cash and meeting those sorts of targets and hoping to focus investors there as well.
Also on the can you comment a little bit on cash generation, especially considering that you have a safe harbor goal now that might require somewhere around $100,000,000 of cash, I think, I calculate?
Michael, so it's Edward again. So in my section, we described this a little bit. We expect equity capital deployed against the Safe Harbor strategy to be about $25,000,000 It's possible it could be more or less at exactly December 31 based on the exact inflows and outflows of payments in and out of the facility because that will be a busy time of year for us. But we do have and do it we do expect to close here the quarter, a significantly high LTV facility to finance the equipment that we are purchasing in support of that Safe Harbor program.
So maybe 2. Great. One last I might add to that are just that. So the cash generation target of $100,000,000 would exclude that $25,000,000 that $25,000,000 investment. And so we would show you that specific add back line.
And then in terms of just as we've described it historically, we believe that that's a repeatable this is a repeatable target for us annually.
That's great. And one last question about the Comcast deal. Just wondering if you hit the Q3 targets, 6,000 customers, I believe it was. And does this change the targets for December and going forward?
We do not expect Comcast to reach their the equity warrant piece of the contract. As we've been discussing in previous quarters, they for their own competitive reasons haven't really pushed this into their core business. So it's really been operating as a sort of siloed business development program. And we've really deemphasized it. We just think that there are we're seeing lots of demand in attractive acquisition channels.
So you will not see that as it doesn't represent any material amount of installations and I wouldn't expect to see that going forward.
Thank you very much. So just
crystal clear, we wouldn't expect any dilution from that agreement.
Got you.
And your next question comes from the line of Joe Alsha with JMP Securities. Please go ahead.
Hello. There are a couple of questions. 1st, not to beat the safe harbor horse too much. I hear the equity capital number. Can you give us a sense as to what the gross capital deployment is going to be to cover that 500 megawatts?
Hi, Joe. It's Ed. Fair question. We are going to be satisfying the Safe Harbor requirement for all projects using the 5% prong. We will be doing that in a variety of different methods and expect to be describing the details around that, including the financing facility on our next call.
Okay. And just
just just just And you could back
on the
envelope with the 500 megawatts, you could back on the envelope with the average asset.
And might you guys be using the physical work standard as part of that?
We do not anticipate using any physical work standard.
Okay. Second question, kind of seems like you guys are settling into pre flip plus subordinated debt follow-up in the Q4 and then a post flip in the Q2 sort of cadence. Is that when I think about 2020, can I sort of expect the same profile of transactions over the course of the year?
Great question, Joe. So absolutely, we have been active with both pre flip and post flip transactions this year. And over a multiyear period, I would expect that to be the case. And next year, we would probably do approximately 2 such transactions. Whether or not we do another refinancing next year or 20 21 is undecided.
So I wouldn't want to guarantee that at this point. And again, we can talk more about that on the 2020 call.
All right. Cool. And then last question, you saw some Bay Area CCAs talking about going out to some behind the meter storage, I guess, firming. And then there's this big CPUC all sources solicitation, which I suspect is utility scale, but that might sort of flow through to CCA's coming to you guys as well. So I'm just wondering how you guys are thinking about the opportunity for grid services revenue in the context of all of this chaos here in the state?
Yes, Joe, that's a great question. I think, actually the CCAs are potentially stepping into a leadership role in thinking both about the delivery of renewables and resiliency. And I think part of that is just that's sort of in their mission to do and part of it is obviously they're not distracted And so, we do think there will be increasing opportunities to work with CCAs on solar and solar plus storage, both for resiliency purposes, but also just for regular capacity, which obviously is related. And so we haven't made any announcements on that of late, but there are discussions underway. And I would expect over the coming year that there'll potentially be more to talk about there.
I would say and we have, of course, announced the Oakland the program with Oakland, which we talked about last quarter. And I think we're pursuing a 2 pronged approach here. One is just let's just go direct to consumers and deliver superior service with Brightbox product. And then at the same time work the regulatory and the partnerships to make sure that we're leveraging those assets for the benefit of everybody and valuing all the services and setting up the Brightboxes to actually contribute all the services they can. So we expect that the direct to consumer route is probably the least friction.
You get that going fast. And then in parallel, as we get our footprint increased, you can't ignore us anymore. We can provide a lot of services to the CCAs and to the IOUs that are more cost effective than the traditional centralized way of doing things.
Agreed. Thank you very much.
And your next question comes from the line of Eric Lee with Bank of Please go ahead.
Hey, good afternoon. Thanks for taking the question. Hi. Can you hear me? Yes.
So just a quick question around expectations for growth in NPV into 2020 beyond. Could you just talk a bit about efforts to mitigate full year 2019 specific headwinds that are impacting guidance? And how should we think about I know you talked about 15% to 20% growth into 20% plus and I mean could you clarify around NPV as well? Should we expect normalization maybe towards the $1.15 again? Thanks.
Great question. We as we described, the growth rate in the orders is the 15% to 20% in Q3 and Q4. We don't see any reason why that would subside. We're not in a position to give any formal 2020 guidance at this stage. That will be next call.
And so piggybacking on my answer for Brian's question, we're putting into place all of the blocking and tackling to make sure that we have the capacity. And so we think that's a it wasn't an overnight improvement, but we expect in a couple of quarters we'll be caught up. So we'll see some backlog into Q1, but we should be caught up directionally by then.
And could you talk about the NPV expectations? Yes, NPV.
Sure, sure.
Yes.
Sure. Sorry. Yes. So the NPV is depressed this quarter because of that mismatch. So as we start to deliver the growth in Q4, you're going to see it above $1 And so we would expect that it would normalize above $1 into those historical
rates. And could you just clarify again on full year 2019 NPV guidance? I know you guys put out $1 per watt plus, but I believe, Bob, if you could clarify, you made a comment about towards full year 2018's NPV?
Yes. So I think we've said above $1 for the full year is the official guidance. And my comment was that I thought we would approach near last year's overall NPV for the full year.
Okay. That's helpful. And one last question for me before I pass it on. Could you just briefly talk about drivers of that backlog growth be it from retail, homebuilder partnerships, etcetera? Thank you.
Sure. It's been really across all of our acquisition channels. So it's we're a multichannel business. It's one of our competitive advantages. So it's across our customer referrals, our digital marketing, our retail presence, our channel partners.
And as I've said on multiple calls, the new home, the new home builders is a slower build. It's a meaningful policy because it normalizes solar and makes it more exposed to people, but it's not a meaningful size of our installed megawatts or installed sale or even bookings at this stage. So nothing meaningful moved around this quarter versus previous ones.
And your next question comes from the line of Sophie Clark with KeyBanc. Please go ahead.
Hey guys, how are you? Can you hear me?
Yes. Yes. Hi, Sophie.
Great. Terrific. Just had a question on the share buyback program. Obviously, that's something that's new to you. And what gives you confidence that you're at the right place to start something like that now where you are at the company?
Hi, Sophie. So it's Ed. So I think we've been talking about a share buyback program for some time. It's been a Board topic for a while. It's come up on calls.
And I think that the considerations that we've had in the past have included uncertainty around the Safe Harbor size of program and the equity capital necessary to execute it. And with that, in the rearview mirror, with the sustained growth of the business and cash generation and with the amount of capital that we have on the balance sheet today, all those things sort of came together, I think, in this Board discussion to give everyone the enthusiasm to launch such a program and begin building that muscle to the company.
Thank you. And one more from me, if I could. So the labor market shortages initiatives, it just doesn't seem like something that will dissipate on its own, like short of a 7 recession, right? But I'm sure you can find pockets of and it's just not going to operate locally and maybe there's higher unemployment. Is it an option at all to sort of create this mobile workforce, if you will, and trace people from these regions and then deploy them elsewhere?
Like, have you considered doing something like that? That's all.
So I'll just repeat the question. I believe that your comment is that the labor market shortages may persist. Are there creative opportunities to produce a mobile workforce? We're so one, I would say, yes, they do. We do believe though that we can be a preferred employer with our national scale, with our training programs, their career development.
And so while, again, you're going to see 9% growth quarter over quarter to Q4, so you see some progress against that. And But I would also say our scale is not that huge. So we're we have 600 open positions. So with the right blocking and tackling with our market position, we believe that's achievable.
Thank you. Thank you.
And your next question comes from the line of Philip Sheehan with Roth Capital Partners. Please go ahead.
Hey guys, thanks for the questions. I'd like to explore the labor topic a little bit more. I know we've touched on this a bunch and you've mentioned that you're confident in resolving this in a couple of quarters. I think last quarter you were confident in resolving this as well before Q4. And so our checks with the industry suggest it is incredibly tight out there.
You do have 600 positions, more than 600 to fill. So I know your long term goal is to grow 15% to 20%. And with your guidance for Q4, I think you're going to grow maybe 11% year over year in 2019 versus your prior guide of 16% to 18% year over year growth. One of your peers is growing 18%, another one growing 30%. I know you're not going to provide official guidance till next quarter, but can you comment directionally on your 2020 outlook?
Could we see something similar to 2019 where it's sub-fifteen percent growth because of this labor issue? And then also as it relates to your confidence, what would need to happen in order for this to be longer than a couple of quarters, for example? And what kind of probability might that be?
Thanks, Phil. So one, I would just point you to a couple numbers to give more confidence. So one, if you just look trailing 12 months, the growth in our megawatts deployed was 20%. So it's a share taking number versus any of the peer companies. Secondly, I think I would point to the sequential growth from Q3 to Q4, where the sequential growth in the quarter is 9%.
So if you just look at that as a indication of some of the momentum in the business that, that would support the type of growth rates that you're talking about. So that's what gives us some confidence there. We also the seasonality will help as well to Brian Lee's question. And then we are also not only do we have the levers of our direct hiring, but we also have the 3rd party. And so there's more for us to put in place programs with 3rd parties for sustainable business for them.
So it's a lot of blocking and tackling. But again, we're operating at a scale that's bigger than our peers. But again, it's not it's a scale that is 100, if not thousands of people. So it's an executional challenge. And we think that the Q3 to Q4 growth rate should provide some confidence that the momentum is going in the right direction.
Okay. Thanks, Lynn. Shifting gears to your contracted value, it's down to $331,000,000 this quarter. I think it's down 25% year to date. How do we how should we think about or how do you think about this line trending ahead?
Do you think the contracted value can grow near term? And over the past year, you've deployed, probably year to date, nearly 300 megawatts. And this is in contrast with the contracted value going down. So it suggests that you're selling assets and maybe even residual equity. Are you selling the equity slices in these assets?
And if you can comment on that overall outlook for that line item, that would be great. Thanks.
Sure, Phil. This is Ed. So great questions and a few things I would like to share on the topic. So the first one is we haven't made any asset sales. And when we think about net earning assets, we really think about it in concert with cash as a first And our cash position is up $100,000,000 over the trailing twelve month period, and that's despite the fact we've been making very significant working capital investments.
So for instance, to the earlier comments on the call, all of the sales that we've incurred that have not yet become installed affect cash but do not benefit net earning assets. If you look on the balance sheet, you'll see construction and process is also up $45,000,000 year to date. So that's further investments. And so actually, we think when you look at cash and net earning assets together, it's quite a positive story. I would also mention, and this gets to the 6% discount rate, that with actual interest rates being where they are, and with the finance execution that we've been achieving, we can actually realize more than 100% of contracted net earning assets.
So it would be possible to do no refinancings, sell no assets, grow cash significantly and actually see contracted net earning assets decline because at a 6 percent discount rate, it's not really appropriately mark to market. If you use the 5% discount rate to examine net earning assets, it would be $405,000,000 higher, about half of which is in the contracted period. So we think that, that altogether is a very attractive story for the company and for cash generation. And absent, obviously, remarking everything in the materials, it may not it may undersell the actual performance of the business.
Okay. Thanks, Ed. One last one. Can you provide us an update on your plans around the new home build markets? For example, are you guys partnering with roofing contractors or do you feel like you can go direct to the builders?
Our checks suggest that you might be partnering with Citadel Roofing, which has healthy market share in California as a path to the builders. Can you expand on this topic and just provide some color there? Thanks.
Thank you. Yes, we are pursuing both. Again, that's one of the advantages of our model is that we have our direct efforts as well as our partnership platform. So we did last month announce a partnership for new homes with Citadel, which is one of California's largest roofing companies. And we remain engaged with conversations and we remain engaged with conversations or have been contracted with half of the top 10 homebuilders in California.
So again, as I said in the past, the way these relationships typically work is you get awarded a community or 2, you prove yourself, you get awarded more. So it's a slow build, but we like the progress that we've made to get in there and prove ourselves we're a high quality partner. Plus, we will continue to pursue these partnerships with the Citadel and others. I would also add that the safe harbor adds an interesting competitive advantage to this as well. I believe with our scale, we're safe harboring the largest number of megawatts.
And so for the builders who really prefer the solar as a service business model, since it doesn't require any upfront capital, There's a sustainable and durable advantage for us that will persist for the next 4 years, 4 years plus with the 10% credit in that market.
Okay, great. Thanks. I'll pass it on.
Thank you. And your final question comes from the line of Colin Rusch with Oppenheimer. Please go ahead.
Thanks so much for squeezing me in. Can you talk about the available capacity you have on the energy storage side to meet the needs of the demand? And are you supply constrained at all at this point?
In terms of the physical hardware, we are not supply constrained on the batteries. So this again, though, it overlaps with the markets where we have installation constraints. So it's the same conversation we've been having in the previous conversations. But in terms of the batteries themselves, we are not constrained there.
Okay. And then just as you look at the technology landscape and moving towards virtual power plants and other services that you can provide. Are you seeing meaningful evolution in technology and a shift in terms of what you would want to include in the portfolio. Obviously, you guys have been pretty good about managing vendor risk, but I'm wondering if there's maybe a shift in terms of how you think about technology exposure and technology needs as you move into the next phase of the business?
I think we're excited about all the innovation that's happened in the batteries. I mean, that's tailwind. We have not seen those price reductions happen. But when we look at the landscape out there, there's a with electric vehicles coming and the amount of innovation that's happening here, there are many suppliers working on the next generation of batteries, which will be easier to install, cheaper to install, higher capacity. And so those are all on the come.
So I would say that we're excited about that. The product
Okay. Thanks, guys.
Thank you.
And I'm showing no further questions at this time. I would now like to turn the conference back to Lynn for closing remarks.
Thank you, everybody. Hope you have a lovely evening.
And this concludes today's conference call. Thank you for your participation and have a
