Speaking this morning are David Anderson, President and Chief Executive Officer, and Frank Burkhartsmeyer, Senior Vice President and Chief Financial Officer. David and Frank have prepared remarks and then will be available along with other members of our executive team to answer your questions. With that, I will turn it over to David.
Thanks, Nikki. And good morning and welcome everybody. We continue to see strong financial results that are in line with our expectations and the guidance that we provided earlier this year. Frank will go through more of the details here in a moment. This morning, I'll walk through some economic indicators for Oregon and Washington and provide an update on our Oregon general rate case. I'll wrap up with some exciting efforts related to hydrogen and gas utility and an update on our water and competitive renewables business. Turning to a few comments on the economy. In our service territory, we continue to experience growth despite a dynamic macroeconomic backdrop. Reports in the first quarter of 2022 ranked Oregon in the top 10 states for the change, positive change in GDP.
That outperformance is based on stronger than average growth in real estate and the healthcare industries as the Oregon economy continues to rebound after COVID. The labor market also remains robust with low unemployment and strong employment gains. In Oregon, unemployment was 3.6% in June 2022. That's nearly as low as the pre-pandemic levels of 3.4% in February 2020. Single-family housing activity remains solid. The median sales price of a home in our area was up 9.4% for the second quarter of 2022 compared to last year. The inventory of homes for sale in the Portland metro area remains low at 1.4 months of supply. Overall customer growth is in line with our expectations with a dip in mixed-use multi-family construction that we knew was coming.
Single-family adds continue to be strong, driving the addition of nearly 10,200 new customers during the last 12 months, which equates to a growth rate of 1.3%. Our water and wastewater utilities also continue to grow. Strong residential housing construction, primarily in Texas, where our water and wastewater utility posted nearly 11% organic growth. In Idaho, where our Falls Water Company posted 4% organic growth, boosted us to a consolidated 3% customer growth from organic customer growth over the last 12 months. The combination of this organic growth and acquisitions resulted in a 27% increase in our water and wastewater utility connections. Moving to an update on our Oregon general rate case. As you know, 2021 and 2022 have CapEx plans related to spend for safety and reliability, technology system upgrades, and cybersecurity investments.
To recover those costs, we filed an Oregon general rate case in December of last year. The original request included a revenue requirement increase of $73.5 million. That's based on a 50/50 capital structure, a return on equity of 9.4%, and a cost of capital of about 6.9%. In May 2022, we filed a settlement with the main parties in the case related to the majority of the revenue requirement items. That included a revenue requirement increase of $62.7 million, also on a 50/50 capital structure, an ROE of 9.4%, and an overall cost of capital of 6.8%. It also included a rate base increase of $337 million since the last rate case for a total rate base of $1.77 billion.
In June, we reached a second multi-party settlement related to a number of smaller items, including recovery of our COVID deferral. We expect an order from the commission on the full rate case this fall with rates effective November first. With that, let me turn it over to Frank to cover more of the details of the quarter. Frank?
Thank you, David, and good morning, everyone. I will begin by discussing the highlights of the quarter and year-to-date results and conclude with guidance for the year. I'll describe earnings drivers on an after-tax basis using the statutory tax rate of 26.5%. As a reminder, NW Natural's earnings are seasonal with a majority of revenues and earnings generated in the first and fourth quarters during the winter heating months. For the second quarter, we reported net income of $1.7 million or $0.05 per share, compared to a net loss of $700,000 or $0.02 per share for the same period in 2021, an increase of $0.07 per share. The improvement over last year was driven by our gas utilities, which posted an increase of $0.05 per share
Higher earnings at the gas utility were primarily related to higher margin and lower pension expense. Utility margin in the gas distribution segment increased $2.3 million as a result of customer growth and new rates, which collectively contributed $1.7 million. Utility O&M increased $3 million, reflecting higher contractor costs for safety and reliability projects, professional services, and information technology costs. Other income increased $2.1 million, primarily from lower pension expense, reflecting higher returns and lower interest costs. Net income from our other businesses increased $900,000 for the second quarter of 2022 due to higher asset management revenues and lower business development costs.
For the first 6 months of 2022, we reported net income of $58 million or $1.77 per share, compared to net income of $58.8 million or $1.92 for the same period in 2021. The $0.15 decrease in earnings per share is largely the result of the issuance of 2.9 million shares of common stock on April 1. The $800,000 decline in net income for the 6-month period reflects an improvement in gas utility net income of $3 million, while the results from our other businesses declined $3.8 million as the prior period benefited from the higher asset management revenues related to the February 2021 cold weather event. Higher earnings at the gas utility were primarily related to customer growth, new rates in Washington, and colder weather in 2022.
As a result of these factors, utility margin increased $6.1 million. Utility O&M increased $6.5 million, reflecting higher levels of contractor and professional services and information technology upgrades. Utility depreciation and general taxes increased $800,000 due to higher property plant equipment as we continue to invest in our system. Other income increased $3.9 million, driven by lower pension costs. For 2022, cash provided by operating activities was $197 million, in line with the prior year. We invested $170 million into the business, most of which was for the gas utility capital expenditures. Related to our financing cash flows, we had two successful transactions. On April first, we completed an equity offering with approximately $140 million of proceeds to support our growing businesses.
In July, we executed a private placement bond agreement for the gas utility. We plan to close the $140 million transaction and take the proceeds on September thirtieth. I'm pleased with our ability to access the markets and take this financing risk off the table. Last quarter, Moody's and S&P both reviewed the gas utility and reaffirmed ratings and stable outlook. That includes Northwest Natural's senior secured long-term debt rating of AA- for S&P and A2 for Moody's. Our objective remains to keep our balance sheet strong with ample liquidity. Moving on to financial guidance. The company reaffirmed 2022 earnings per share guidance for net income, sorry, in the range of $2.45-$2.65 per share.
Guidance assumes continued customer growth, average weather conditions, and no significant changes in prevailing regulatory policies, mechanisms, or outcomes, or significant changes in laws, legislation, or regulation. We continue to target a long-term earnings per share growth rate of 4%-6%. With that, I'll turn the call back over to David.
Well, thanks, Frank. We continue to focus on the future, making sound investments today that will support sustainable growth for tomorrow. As we shared before, over the last few years, our engineering team has conducted 5% hydrogen blend tests at one of our service centers, our Sherwood Operations and Training Center, with a goal to increase our blending in increments up to 15%, obviously pending system and equipment testing results. We've also been participating in industry-wide partnerships such as HyReady and the Low-Carbon Resources Initiative to share findings and testing information. In parallel with these efforts, we've continued to work collaboratively with Eugene Water & Electric Board and the Bonneville Environmental Foundation on the scoping of a 1-MW power-to-gas facility.
This project has been designed to blend 5% clean hydrogen into a dedicated section of our Eugene distribution serving system, serving about 2,500 customers. The benefits go well beyond our Eugene customers. This partnership with EWEB will provide hands-on experience in the generation, distribution, and storage of clean hydrogen across Oregon's increasingly interdependent gas and electric grids. We've already begun preliminary outreach with various stakeholder groups representing the local community, regulatory staff, elected officials, industry groups, and customer advocates. In July, we filed a request to open a docket with the Public Utility Commission of Oregon to recover the cost of the project under Senate Bill 844. This law is innovative and unique to Oregon, supporting gas utility projects that are designed to reduce greenhouse gas emissions.
If approved, this Eugene project could be Oregon's first clean hydrogen production facility, serving to demonstrate the applications of this versatile energy source and the important role it will play in decarbonizing both the gas and electric systems. In July, we also announced that Northwest Natural is partnering with Modern Electron on an exciting turquoise hydrogen pilot project to turn methane into clean hydrogen and solid carbon. We'll be testing this groundbreaking technology at our Portland operations facility. The innovative process is designed to produce hydrogen and solid carbon using only natural gas and air as inputs, and to not use any electricity, water, or consumable catalyst.
It's an incredibly sustainable and flexible way of producing hydrogen, and if scalable, has the potential to allow us to produce clean hydrogen whenever needed to decarbonize our system at potentially a very low cost. It also produces valuable byproducts that can be used to make tires and dye, among other things. This project is in partnership with Modern Electron, a Seattle-based sustainable heat and power technology company that has funding support from Microsoft's founder, Bill Gates. We expect the project to go live in early 2023. We believe that clean hydrogen, along with renewable natural gas, energy efficiency, and equipment innovation are critical to achieving our goals of greenhouse gas emissions reductions. We're committed to preparing our system and employees for any changes in equipment, operations, and training that working with a blended gas might require.
Moving now to an update on our competitive renewable natural gas business that we launched late last year. As you know, we focus on providing cost-effective solutions to help a variety of sectors decarbonize using existing waste streams and renewable energy resources. Our first project with EDL includes an investment in two renewable natural gas facilities and a 20-year RNG supply agreement. Construction is ongoing at both RNG facilities, and we expect them to be placed into service in early 2023. The team is fully engaged, pursuing incremental opportunities and putting the final touches on the business plan, which we will share in more detail later this year.
Turning to our water and wastewater utility businesses, as previously mentioned, in December 2021, we signed our largest acquisition to date to acquire Far West Water & Sewer, Inc. in Yuma, Arizona, a fast-growing region which currently serves approximately 25,000 customers. In March, we submitted the application for approval of the transaction with the Arizona Corporation Commission. In June, Arizona staff recommended the commission approve the acquisition. The next step is obviously for commission review. We expect the commission's decision in August or even early September, and subject to its approval, expect to close the transaction as soon thereafter as we can. We expect the transaction to be accretive to earnings per share after its first full year of operations. We remain excited about the investment potential for this business and look forward to more announcements soon.
In conclusion, we're off to a good start for the year with continued customer growth at the gas utility, water, and wastewater utilities. Thanks for joining us this morning. With that, we'll open it up to questions. Seth?
Thank you. As a reminder, to ask a question, please press star one on your telephone keypad. Our first question comes from Julien Dumoulin-Smith from Bank of America. Please go ahead.
Hey, it's Kody Clark on for Julian. Thanks for taking my questions.
You bet, Cody.
First, can you talk through the dynamics and expectations for pension expense in the next year? I know there's a lot of moving pieces that could change through the remainder of the year. If we look at it today, what do you estimate the impact is for 2023? You would have to go through a rate case for recovery of that, correct?
Hey, Kody, it's Frank. Yeah, great question. You know, we've seen about $0.05 per quarter benefit year-over-year from lower pension expense, and we expect that to continue through the year. We set the rates for the year, essentially. It's when you set the discount rate at 12/31, sets pretty much the expense for the year, other than just a little bit of fine-tuning. We think this will continue through the year. It's driven, interest rates are higher, so discount rates are higher. Asset performance was very good over the last couple of years, so we've got a better asset funded position. Yes, that goes into rates, and it's forecasted to our test year for rates.
That'll be in our Oregon case, and November first, that'll be reflected there. We don't see a big change in that right now. It is just kind of reset. As long as interest rates and asset performance are kinda in the same range, we don't expect big changes going forward here. It's been an improvement as both of those have improved.
Right. If I'm thinking about 2023 and discount rates, yes, higher. Asset performance likely a lot lower. I guess just the net impact of that, do you have a view on that into 2023?
Yeah. I mean, right now, and again, we'll have to set rates at the end of the year, so it'll depend upon where assets and discount rates are at the end of this year. Just when we look at it today, we're not seeing a lot of change net net. You've seen interest rates go up since year-end last year, and you've seen assets come down. Net net, we're in very much the same position. If I had to do it today, if I had to make a guess today, I'd say I'm not expecting a lot of change.
Okay. Got it. Second, just wondering if you can talk through the latest trends you're seeing with inflation and the impact on the O&M budget and capital plan looking forward. Also, any mitigating measures or procurement strategies that you're implementing?
Yeah. Great, another great question. From a supply chain standpoint, which is all kind of interrelated, we're not seeing a tremendous disruption there. We're, you know, it's a little bit slower delivery time on meters and some of the pipe and such, but we're not seeing a disruption to our business, to our projects. We've been going through this. We're being more proactive. We're extending our orders out. We're building up our inventories and such, as you might expect. We are seeing inflationary impacts on materials, but materials are actually a fairly small component of our cost structure. We're more labor-based, whether it's internal labor, third-party labor, other contracted costs.
Most of our costs are under multiyear contracts, a lot of them with fixed escalators, but that's what we expect and what we build into rates and into our forecasts. We're not seeing any tremendous disruptions at this point just from inflation.
We will, you know, over time we will see more of that as our locate contracts and our labor agreements and all of those reprice over time. We will see some of that inflation come through, but I think it's in a manageable structure. Within the year, interest rates are definitely up. We've got some short-term debt at both the utility and the holding company, so we see that some headwinds there. We saw that early in the year. We put in place some cost control measures that have allowed us to get a head start on that and not overreact.
We've got a pretty good bead on the year, and we're managing to our cost just based upon staffing levels, third-party costs, discretionary expenses, the sort of things that you would ordinarily manage, a workflow, those sorts of things, or work mix. We feel like we've got a really good program in place there to manage through this year on that, Cody.
Great. Sorry, just one quick follow-up to that as we're looking at 23. Any large sort of renegotiations of contracts that we should be keeping an eye on?
No. Our big contract here is always going to be our union contract. That's, I think that's got 2 years in it still, so we just renegotiated that a couple of years ago. That's a couple of years out. You know, every year we've got, you know, it might be the paving contract or the locates, et cetera, come up, but no one of them presents a particularly large change. When we do our rate cases, we look forward as to what the major contracts will be, so I think we're in good shape there.
Got it. Thanks so much for the time. I'll pass it off there.
Thanks for the questions.
As a reminder, for any further questions, please press star one on your telephone keypad. As we have no further questions at this time, I will hand the call back to David Anderson.
Thank you, Seth. We know it's a busy day out there, everybody, and there's multiple calls going on. For those of you listening to this later, if you have any questions, please reach out to Nikki, and she will take care of you as she always does. Thank you for joining us today, and look forward to seeing you soon. Take care, everybody.
This concludes today's conference call. Thank you all very much for joining. You may now disconnect your lines.
