per share versus the year-ago quarter. Lastly, taxes and other items were $0.01 per share unfavorable compared with the third quarter of 2020.
Total generation output of 14.9 TWh matched the output of third quarter 2020. PSEG Power’s CCGT fleet produced 6.8 TWh of output in response to higher market prices. The nuclear fleet operated at an average capacity factor of 94.8% for the quarter, producing 8.1 TWh, which represented 54% of total generation. For the balance of 2021, PSEG Power is forecasting total baseload and combined cycle generation of 12 to 14 TWh, hedged 85% - 90% at an average price of $32 per MWh.
Expected gross margin of over $1 billion for 2022, excluding Fossil results, is over 90% hedged via forward energy sales, approximately $156 million of capacity revenues, and Zero Emission Certificates. For 2022, 2023 and 2024, nuclear output is forecast to be 31, 31, and 30 TWh, respectively. Our ratable hedging approach, executed over a rolling three-year basis, helps to stabilize gross margin from market volatility. Consistent with that methodology, our projected baseload output is currently over 90%, 75-80%, and 35-40% hedged at prices averaging $29, $28, and $29 per MWh for the years 2022, 2023, and 2024, respectively, which is in line with the historical forward prices for those corresponding years.
PSEG Power has raised the forecast for its non-GAAP Operating Earnings for 2021 to $365 million - $440 million, from $350 million - $425 million prior. Our estimate of non-GAAP Adjusted EBITDA has also been raised to $870 million - $970 million, from $850 million - $950 million prior.
