Great. Thank you, Ralph, and good morning, everybody. Earlier, Ralph mentioned that PSEG reported net income of $591 million, or $1.18 per share for the second quarter of 2023, compared to net income of $131 million, or $0.26 per share, for the second quarter of 2022. Non-GAAP operating earnings for the second quarter of 2023 were $351 million, or $0.70 per share, compared to $320 million or $0.64 per share for the second quarter of 2022. We provided you with information on Slides 9 and 11 regarding the contribution to non-GAAP operating earnings per share by business for the second quarter and year-to-date periods. And Slides 10 and 12 contain waterfall charts that take you through the net changes for the quarter-over-quarter and year-to-date periods in non-GAAP operating earnings per share by major business.
Starting with PSE&G, which reported second quarter 2023 net income of $336 million, or $0.67 per share. This compares to $305 million, or $0.61 per share, in the second quarter of 2022. Second quarter 2023 non-GAAP operating earnings were $341 million, or $0.68 per share, compared to $305 million, or $0.61 per share, in the second quarter of 2022. The main drivers for both GAAP and non-GAAP results for the quarter were growth in rate base, reflected in higher transmission formula rate, recovery of infrastructure investments with rolling mechanisms, and a benefit from the reversal and timing of taxes, which we mentioned on the first quarter call net to zero over the course of the year. These favorable items were partly offset by our anticipated lower pension income and OPEB credits, along with higher depreciation and interest expense from increased investment versus the year-earlier quarter.
Compared to the second quarter 2022, transmission was $0.02 per share higher. Gas margin was $0.01 per share higher driven by the clause recovery of GSMP investment. Electric margin was $0.01 per share higher, reflecting investment returns from Energy Strong. And other electric and gas margin added $0.02 per share based on a benefit from the tax adjustment credit and appliance service results. Lower distribution O&M expense added $0.02 per share compared to the second quarter 2022, primarily reflecting reduced weather-related corrective maintenance. Depreciation and interest expense increased by $0.01 and $0.02 per share, respectively, compared to the second quarter of 2022, reflecting continued growth in investment.
Lower pension income resulting from 2022's investment returns, combined with lower OPEB credits scheduled to end in 2023, resulted in a $0.04 per share unfavorable comparison to the year-earlier quarter. Lastly, the timing of taxes recorded through an effective tax rate, which nets to zero over a full year, and other flow-through taxes, had a net favorable impact of $0.06 per share in the quarter compared to the second quarter of 2022. Second quarter weather typically contains both heating and cooling sales. For 2023, winter weather during the second quarter was 23% warmer in terms of Heating Degree Days than the second quarter of 2022. And summer weather was 34% cooler than second quarter 2022 as measured by the temperature humidity index.
As we've mentioned, the SIP mechanism in effect since 2021, limits the impact of weather and other sales variances, positive or negative, on electric and gas margins, while importantly enabling PSE&G to promote the widespread adoption of its energy efficiency programs. Growth in the number of electric and gas customers, the driver of margin under the SIP mechanism, continues to be positive and were each up 1% during the trailing 12-month period.
On capital spending, PSE&G invested $900 million during the second quarter and is on plan to deliver its largest annual capital investment program at $3.5 billion. The program includes upgrades to our T&D facilities, Energy Strong II investments, last mile spend in the infrastructure advancement program, and the continued rollout of the clean energy investments in energy efficiency and the Energy Cloud including smart meters. Related to our pension, in February 2023, the BPU approved an accounting order authorizing PSE&G to modify its method for calculating the amortization of the net actuarial gain or loss component for ratemaking purposes. This change was effective for the calendar year ending December 31, 2023 and forward. For the full year 2023, PSE&G's forecast of non-GAAP operating earnings is unchanged, At $1.5 billion to $1.525 billion.
Moving onto power and other. Just as a reminder, power and other includes our nuclear fleet, gas operations, Long Island, and parent activities, including interest expense. For the second quarter 2023, PSEG Power and other reported net income of $255 million, or $0.51 per share, and non-GAAP operating earnings of $10 million, or $0.02 per share. This compares to second quarter 2022 net loss of $174 million, or $0.35 per share, and non-GAAP operating earnings of $15 million, or $0.03 per share. We previously mentioned that during the first quarter of 2023, PSEG Power realized the majority of the approximate $4 per megawatt hour increase in the average price of our 2023 hedged output, which rose to approximately $31 per megawatt hour with higher winter pricing driving most of the increase.
For the second quarter of 2023, gross margin rose by a total of $0.05 per share, reflecting the absence of certain full requirement BGS load contracts that remained following the sale of the Fossil business in 2022, and resulted in a lower cost to serve compared to the prior year. The increase in gross margin includes higher generation of $0.01 per share from fewer refueling outage days in the second quarter of 2023, offset by lower capacity revenues of $0.01 per share compared to the year-ago quarter. O&M cost comparisons in the second quarter improved by $0.01 per share in 2023. Higher interest expense covering PSEG Power and parent financings were $0.02 per share unfavorable compared to the year-ago quarter from higher variable rates on term loans and refinancing maturing debt at higher rates. Lower pension income from 2022 investment returns and OPEB credits from the lower amortization benefit mentioned earlier were $0.03 per share unfavorable versus the second quarter of 2022. And taxes and other were $0.02 per share unfavorable compared to the second quarter 2022, reflecting a partial reversal in the effective tax rate benefit from the first quarter and lower investment income.
On the operating side, the nuclear fleet produced approximately 7.7 terawatt hours during the second quarter and 16 terawatt hours for the year-to-date period in 2023, running at a capacity factor of 91.2% for the quarter and 95.8% for the year-to-date period. For the full year 2023, PSEG is forecasting generation output of 30 terawatt hours to 32 terawatt hours and has hedged approximately 95% to 100% of this production at an average price of $31 per megawatt hour. For 2024, the nuclear fleet is forecasted to produce 30 terawatt hours to 32 terawatt hours of baseload output and has hedged 75% to 80% of this generation at an average price of $38 per megawatt hour. The forecast of non-GAAP operating earnings for PSEG Power and other is unchanged at $200 million to $225 million for the full year. This forecast reflects the realization of a majority of the expected increase in the average 2023 annual hedged price in the first quarter of '23 as we previously discussed.
Touching on some recent financing activity. As of June 30, 2023, PSEG had total available liquidity of $4 billion, including $500 million of cash and cash equivalents on hand. PSEG Power had net cash collateral postings of approximately $400 million at June 30, which is well below the levels experienced during 2022. Through the second quarter, we've repaid $2 billion of term loans, which were entered into during 2022, to support our collateral needs. In April, we entered into a $750 million 364-day variable-rate term loan to support our liquidity needs. As of June 30, 2023, PSEG had $750 million outstanding of the 364-day variable-rate term loan, and PSEG Power had $1.25 billion outstanding of a variable-rate term loan maturing March of 2025. As of the end of the quarter, PSEG had swapped $900 million of the power term loan from a variable rate to a fixed rate. And in May, PSE&G paid, at maturity, $500 million of secured medium-term notes.
As Ralph mentioned earlier, PSEG recently executed an agreement for a pension lift-out that will further increase the predictability of our financial results. This transaction covers approximately 2,000 retirees from PSEG Power and other, and will transfer approximately $1 billion dollars of related obligations and associated plan assets. This transaction will have no material impact on PSEG's non-GAAP operating earnings in 2023. Upon completion of the pension lift-out, we anticipate taking a onetime non-cash settlement charge in the third quarter of 2023 related to the immediate recognition of unamortized net actuarial loss associated with the portion of the pension involved in the transaction. After providing for the effect of this transaction, our pension plans remain well-funded.
As Ralph mentioned, we are reaffirming PSEG's full year 2023 non-GAAP operating earnings guidance of $3.40 to $3.50 per share with PSE&G forecasted to contribute between $1.5 billion to $1.525 billion, and PSEG Power and other forecasted at $200 million to $225 million. The settlement charge related to the lift-out is not included in the full year 2023 non-GAAP operating earnings guidance for PSEG, PSE&G, or PSEG Power and other.
That concludes our formal remarks. And operator, we are ready to begin the question-and-answer session.
