Jason P. Wells
President & Chief Operating Officer at CenterPoint Energy
Thank you, Dave. And thank you to all of you for joining us this morning for our fourth quarter call. I want to echo Dave's thanks to all of our employees here at CenterPoint and express my sincere gratitude for the great work of our teams during these recent periods of inclement weather. From those who sacrificed their holidays, so that customers throughout our service territories could enjoy theirs, to those that helped recently resource service after the extreme tornado activity in late January, and now recently, the crews who have helped with restoration efforts after the recent ice storms in other parts of Texas. It shows we have a committed and talented workforce dedicated to delivering for our customers and our shareholders.
I'll start by covering the financial results for the quarter shown on Slide 5. On a GAAP EPS basis, we reported $0.19 for the fourth quarter of 2022. As in previous quarters, our GAAP EPS results include a portion of the tax on the gain on sale of our Arkansas and Oklahoma gas LDCs, which we are required under GAAP to recognize over the course of the full year.
The quarterly results also include a one-time non-cash charge of $0.06 net of tax related to the de-risking of our long-term pension exposure, which I'll discuss in more detail in a few minutes. On a full year basis, we reported a $1.59 per share, which also included the gains from the sale of the previously mentioned gas LDCs, in addition to the sales of the Energy Transfer common and preferred partnership units earlier this year.
On a non-GAAP basis, we reported $0.28 for the quarter of 2022 compared to $0.27 in the fourth quarter of 2021 and a $1.38 for the full year of 2022 as compared to $1.27 for the full year of 2021. This is 9% growth on top of 2021, in which we also grew 9%. This is an industry-leading growth rate. Growth and rate recovery contributed $0.06, largely driven by continued rate recovery through our electric distribution capital tracker, the DCRF and our electric transmission tracker TCOS in our Houston Electric territory. In addition, we continue to see strong organic growth in the Houston area with another nearly 2% increase in residential growth over last year.
Weather and usage for the fourth quarter was also a favorable $0.02 when compared to the same quarter of 2021, driven by a combination of extremely mild weather in the fourth quarter of 2021 as compared to more seasonally normal weather in the fourth quarter of 2022. These favorable drivers were partially offset by higher interest expense of $0.06, primarily driven by higher interest rates and $0.01 related to absorbing costs previously allocated to our midstream segment in 2021.
I want to briefly touch on O&M for a moment. We continue to find savings opportunities to achieve our reduction target of 1% to 2% per year on average over the course of our 10-year plan through 2030. For the year, we were $0.02 unfavorable as compared to last year. However, as you'll remember, due to favorable weather during last summer's hot months, we were able to pull forward O&M from 2023 for the benefit of our customers. This is consistent with the approach we used in 2021, and should we have weather benefits in 2023, we will certainly contemplate doing so again. Overall, I continue to remain pleased with our ability to drive efficiencies in our business and remain confident, we can continue delivering on our goal of reducing O&M 1% to 2% annually on average.
As Dave mentioned, we are reaffirming the full year 2023 guidance range of a $1.48 to a $1.50 of non-GAAP EPS, which reflects 8% growth over the full year 2022 non-GAAP EPS of a $1.38, when using the midpoint of the previously increased guidance range. Beyond 2023, and from the reaffirmed 2023 guidance of a $1.48 to a $1.50, we continue to expect to grow non-GAAP EPS 8% in 2024, and at the mid to high-end of 6% to 8% annually thereafter through 2030. Our focus continues to be on delivering strong industry leading growth each and every year.
Turning to capital investments on Slide 7. As Dave mentioned, for the benefit of our customers, we invested $1.6 billion in the fourth quarter and $4.8 billion over the full year in 2022. This is a $1 billion or a 25% increase from the target we provided at last year's Analyst Day. Much of this increase was due to or nearly $500 million investment in our temporary emergency mobile generation units and the accelerated resiliency related investments we pulled forward as part of the nearly $3 billion increase to our capital plan outlined on our third quarter earnings call. The capital that was pulled forward to 2022 included capital deployed in the fourth quarter to support the rapidly expanding Texas Medical Center. All of these investments are driven by our continued focus on safety, resiliency, reliability, growth, and clean energy enablement of our service.
Turning to our generation-related investments, we've made good progress on our current Integrated Resource Plan, including the last filing for generation and owned wind project that we expect to come online sometime in 2024 or early 2025. And the IURC's approval of our 130 megawatt owned solar project, and we re-filed PPAs associated with two solar facilities to accommodate various developer price increases. These projects in addition to the ones already in service total approximately 800 megawatts of expected owned and contracted solar generation, which tracks well against our IRP goals that called for approximately 700 to 1,000 megawatts of solar and approximately 300 megawatts of wind. As it stands for the current projects, we expect to own approximately 60% of our renewable generation and contract for the remaining roughly 40%.
With that said, and with recent changes in law, namely the Inflation Reduction Act, the proportion of owned and contracted renewables may be different for additional projects included in our next IRP, which we plan to file in the middle of this year. This upcoming IRP should provide guidance on our remaining coal-fired assets, as we've mentioned before, as a foundation for this IRP. Earlier this year, we conducted an all source request for proposal, where we received nearly a 100 proposals from several dozen participants, including wind, solar, and battery storage that will help inform our IRP process. We look forward to working with stakeholders through the IRP process to develop a constructive outcome for our customers that allows customers to achieve bill savings through efficient renewable generation rather than coal generation, which requires significant ongoing O&M expense.
Moving to a broader regulatory update on Slide 8, we have securitization efforts continuing in a couple of jurisdictions. We anticipate receiving securitization proceeds in the coming months in Texas related to the incremental natural gas costs related to winter storm Uri, which will securitize approximately 1.1 billion of these costs. We had anticipated receiving these proceeds before year end 2022, but it has been delayed. This delay has been driven by various stakeholders in Texas exploring alternatives, including potentially appropriating state surplus funds to pay this off in whole or in part for the benefit of our customers. We are supportive of this customer-focused process and anticipate resolution soon.
In addition to the Texas securitization, we recently received approval for our Indiana securitization for approximately $350 million of costs related to the retirement of two coal facilities. This is a first of its kind filing in Indiana, allowing for more affordable transition to cleaner generation sources for the residents of Southern Indiana. We want to thank all stakeholders, including the Indiana Utility Regulatory Commission, and working through this unique process to achieve a constructive outcome for our customers.
Beyond the securitizations, we will continue to recover the $78 million in Texas related to the traditional distribution capital portion of the DCRF, which went into rates in September. We recently received a proposal for a decision from the administrative law judges at the State Office of Administrative Hearings, an agency that is separate from the PUC. Recommending to the PUC, that disallowance of recovery of our temporary emergency generation units, we're disappointed in this proposed decision, as we don't believe this is the correct reading of the law, and now that the case is back in front of the PUC for a final decision. We look forward to a constructive resolution in this case.
As a reminder, we invested in these units following winter storm Uri, where more than half of our Houston area customers were without power for extended periods of time. Texas lawmakers acted quickly and decisively after that event to enact certain measures that would mitigate the impacts of severe weather to Texans. The passing of the bill to allow Texas' PD companies to use temporary emergency mobile generation, which can aid in reducing the number and/or duration of outages during significant load shed events was perhaps the most significant mitigation measure passed into the law following winter storm area.
In fact, these units were deployed as recently as a few weeks ago to get children back into the classroom. After previously discussed tornadoes caused outages throughout the Houston metro area. And just last week we sent some of our units to Austin to be ready to assist in recovery efforts from the recent ice storms. We have and we will continue to advocate vigorously for the use of this critical tool for the benefit of our customers and in a manner that is consistent with the law. We expect a final ruling on our 2022 filing by the end of the first quarter.
Lastly, to cover some credit related topics. As of the fourth quarter, aligning with Moody's methodology, our FFO to debt as reported with slightly below 14% and approximately 15% when adjusted for the $1.1 billion of outstanding debt related to winter storm Uri extraordinary gas costs. As a reminder, we are deferring the interest expense associated with this debt balance until the statewide securitization is issued.
As I mentioned, we had anticipated receiving the bond proceeds associated with the Texas securitization before the start of 2023, which in part is the reason why we're carrying higher than expected levels of commercial paper and floating rate debt at year end. When we received those proceeds, we plan to pay down a mix of floating rate debt and high coupon debt. In addition, we also saw higher gas prices and usage, during the December cold step, which also led to elevated levels of variable rate debt that we believe will be transient in nature as we expect to collect the majority of this balance over the coming months.
To revisit the pension item, I discussed a few minutes ago. We entered into an annuity lift out whereby roughly $140 million of pension plan obligations and corresponding plan assets related to previously divested businesses were transferred to an insurance company. This transaction allowed us to de-risk our future obligations for which we don't receive regulatory deferral. As we've previously mentioned, we get deferral on approximately two-thirds of our pension expense. As a result of this lift out, we recognized a non-cash settlement charge of $47 million, which represented the acceleration of unrecognized losses deferred under the pension smoothing rules. Through a combination of an increase in discount rates and lump sum settlements, including the annuity lift out, our total pension liability was reduced in 2022 by approximately one-third or $700 million.
Our strong cash flow from operations coupled with our efficient recycling of capital, puts us in the position of still being able to offer industry-leading growth that doesn't require external equity to fund our current 10-year capital plan through 2030. Those are my updates for the quarter. As we continue to express, we take our commitment to be good stewards of your investment very seriously and realize our obligation to optimize stakeholder value.
Now with that, I'll turn the call back over to Dave.
