Executive Vice President and Chief Financial Officer at Public Service Enterprise Group
Thanks, Ralph. Good morning, everybody. As Ralph mentioned, for the third quarter of 2022, PSEG reported net income of $0.22 per share and non-GAAP operating earnings of $0.86 per share. We provided you with information on Slides 8 and 10 regarding the contribution to non-GAAP operating earnings by business, the third quarter and year-to-date periods ended September 30. Slides 9 and 11 contain waterfall charts that take you through the net changes quarter-over-quarter and year-to-date for 2022 and 2021, and non-GAAP operating earnings by major business.
I will now discuss results starting with PSE&G. PSE&G's results were $0.03 higher compared to the third quarter of 2021, driven by continued capital investments in transmission, distribution, and clean energy. Compared to the third quarter of 2021, transmission margin was flat as growth and rate base of $0.02 per share was offset by the combination of the August 2021 formula rate settlement which included a lower return on equity and the timing of O&M expense first recovery.
For distribution, electric margin was $0.02 favorable compared to the third quarter of 2021, driven by investments in Energy Strong II and the impact of the conservation incentive program or CIP mechanism. Gas margin improved by $0.01 per share over the third quarter of 2021, reflecting recoveries of our Gas System Modernization II investments and other margins primarily related to our appliance service business also added $0.01 per share, compared with the third quarter of 2021.
O&M expense was $0.01 per share unfavorable compared with the third quarter of 2021 and interest expense was $0.01 per share unfavorable reflecting higher investment. Flow-through taxes and other items had a net unfavorable impact of $0.01 per share compared to third quarter 2021, driven by the use of an annual effective tax rate.
For the year to date, unfavorable flow through taxes of $0.07 per share year-over-year will reverse in the fourth quarter of 2022. Lower shares outstanding had a $0.01 per share benefit on third quarter 2022 results versus the year-earlier quarter, reflecting the impact of the completed $500 million share repurchase program. And in addition, non-operating pension expense was $0.01 per share favorable compared with the third quarter 2021.
Weather during the third quarter, as measured by the temperature-humidity index, or THI was 19% warmer than normal, but similar to conditions during the third quarter of 2021. With the CIP in effect, variations in weather both positive and negative have a limited impact on electric and gas margins, while enabling the widespread adoption of PSE&G's energy efficiency programs.
PSE&G's system peak load exceeded 10,000 megawatts for a second summer in a row on August 9. And growth in the number of electric and gas customers has continued to track at approximately 1% for the trailing 12-month period ended September 30.
Regarding our capital spending program, PSE&G invested approximately $795 million during the third quarter and $2.2 billion year-to-date through September 30. PSE&G now expects a revised capital-spending forecast of $3 billion for 2022, up from the planned 2022 capital program of $2.9 billion. The 2022 capital spending program includes transmission investment, the continued rollout of the Gas System Modernization Program II, Energy Strong II, and Clean Energy Future investments, and the Infrastructure Advancement Program focused on our distribution system's last mile.
On the regulatory front, in September of 2022, PSE&G filed a petition with the BPU requesting an accounting order with an effective date of January 1, 2023, to authorize PSE&G to modify its method for calculating pension expense for rate-making purposes, which would partly reduce future variability in pension expense.
Also in September, PSE&G filed a petition with the BPU requesting a $320 million, nine-month extension of its Clean Energy, Future Energy Efficiency program, which would serve to align future program timing with the other New Jersey electric and gas utilities. And in October, PSE&G filed its annual Transmission Formula Rate update with FERC, which increases its annual transmission revenue requirement by $69 million effective January 1, 2023.
Now turning to Carbon-Free Infrastructure and Other, which reported a net loss of $285 million or $0.58 per share for the third quarter of 2022, compared with a net loss of $1,953 million, or $3.87 per share in the third quarter impacted by the fossil sale process. Non-GAAP operating earnings were $0.15 per share lower in the third quarter of 2021, driven by lower margin related to the fossil divestiture, lower capacity prices for the remaining nuclear fleet and re-contracting at lower prices. For the third quarter of 2022, electric gross margin declined by $0.29 per share, which includes re-contracting approximately 8 terawatt hours of nuclear generation at a $3 per megawatt hour lower average price.
In addition, higher off-system sales at gas operations from heightened commodity volatility added $0.01 per share to total gross margin versus the third quarter of '21 with customers also benefiting from a long standing sharing mechanism in place. Cost comparisons for the third quarter of 2022 improved by $0.09 per share from the year-earlier period, driven by lower O&M, depreciation and interest expense related to the fossil divestiture. Taxes and other were $0.04 per share favorable versus the third quarter of 2021.
During '21, the Solar Source sale was reflected in June. Cessation of fossil depreciation began in August onward as the assets were held-for-sale, and the retirement of PSEG Power's outstanding debt occurred in October. And accordingly, the majority of the favorable cost comparisons related to the fossil divestiture occurred in the first half of 2022.
Nuclear generating output declined slightly to approximately 8 terawatt hours in the third quarter of 2022, reflecting the ramp down of Hope Creek and Peach Bottom 2 into the fourth quarter refueling outages. The capacity factor of the nuclear fleet for the year-to-date period through September 30th was 94.3%. PSEG forecasts generation output of approximately 7 terawatt hours for the fourth quarter of 2022, and has hedged approximately 95% to 100% of this production at an average price of $27 megawatt hour. For '23, PSEG is forecasting nuclear baseload output of 30 to 32 terawatt hours and has hedged 95% to 100% of this output at an average price of $30 a megawatt hour.
For 2024, PSEG is forecasting nuclear baseload output of 29 to 31 terawatt hours and has hedged 55% to 60% of this output at an average price of $32 a megawatt hour. As of September 30, 2022, our total available credit capacity was $3.4 billion, including a $1 billion at PSE&G. PSEG Power had net cash collateral postings of $2.2 billion at September 30th related to out-of-the-money hedge positions as a result of higher energy prices and that amount was $1.7 billion through last Friday. The majority of this collateral relates to hedges in place through the end of '23 and is expected to be returned as PSEG Power satisfies its obligations under those contracts, or if market prices decline in the interim.
In July of 2022, PSEG repaid a $1.25 billion short-term loan that was due in August. Following the repayment of this term loan, PSEG had outstanding a total of $2 billion of 364-day term loans expiring April, May of 2023 to support power collateral needs. And PSEG Power had outstanding of $1.25 billion term loan expiring March of '25. Combined, these term loans comprise $3.25 billion of variable-rate debt. And during September and October, we entered into interest rate swaps from floating to fixed for $1.05 billion of our outstanding term loans, reducing variable rate debt exposure. Moody's recently published updated credit opinions for PSEG, PSE&G and PSEG Power with credit ratings and outlooks remaining unchanged. Regarding the potential headwinds of pension impact on 2023 costs, we continue to monitor several items that will influence the pension calculations when we take the actual measure on December 31st.
We will assess the net impact of various factors including the decline of financial markets year-to-date, updating the discount rate and interest component, setting the expected return on planned assets for 2023 and the inclusion of the impact of the petition filed with the BPU earlier this year. We will include an estimate of the impacts of pension on our 2023 earnings guidance, which as Ralph said, we will provide at EEI.
As Ralph also mentioned earlier, we've narrowed our 2022 non-GAAP operating earnings guidance to $3.40 to $3.50 per share, with regulated operations contributing approximately 90% of the total. For the full year, PSE&G's forecast of 2022 net income is narrowed to $1,545 million to $1,575 million, reflecting strong transmission and distribution margin growth in the year-to-date period. 2022 non-GAAP operating earnings for CFIO is now forecasted at $160 million to $180 million, reflecting higher interest costs. PSEG's 2022 earnings guidance excludes financial results from the divested fossil assets.
That concludes our prepared remarks. So we can now open up the line to begin the question-and-answer session.
