2024 vs. 2023 (third quarter)
Revenues from electric operations increased $4.4 million, or 6.5%, compared to the third quarter of 2023. While the Merom Facility ran less hours in the third quarter of 2024 compared to 2023, the contracted hours were at higher prices. We have new delivered energy contracts and capacity contracts with sales starting in 2024. We entered into three new delivered energy contracts during the current year which increased revenues by $20.9 million. We entered into three capacity contracts during 2023 that began delivery in 2024 and one new capacity contract that we entered into during the current year, which increased revenues by $10.9 million. Revenue increases from new contracts were offset by suppressed MISO pricing (~66% of total energy hours at the Merom node being priced below our production cost at our Merom Facility), and reductions in demand for Power and higher demand for Gas as Gas inventories remained high, with a continued decline in average spot pricing per MBtu of $2.11 compared to $2.59 during the same three-month period in 2023.
Fuel decreased $21.1 million, or 41.6%, compared to the third quarter of 2023. Our MWh sold decreased by 124 MWh, or 9.5%, from the third quarter of 2023. The decrease in fuel costs are primarily related to our decreased electricity sales and declines in coal market pricing. We used 0.1 million less tons of coal in our electric production compared to the third quarter of 2023. The average purchase price per ton of coal used in the plant on a segment basis, was $53.33 in the third quarter of 2024, decreasing from $76.94 per ton in the third quarter of 2023.
Cost of purchased power was $3.1 million during the third quarter of 2024. As noted above, when energy hours at the Merom Hub are priced below our production cost at our Merom Facility, we make net hourly purchases of power in the MISO market.
Income from operations increased $22.0 million, or 823.3%, and increased $18.39 per MWh, from the three months ended September 30, 2023. The main drivers of this change in income from operations are described in the discussion above.
2024 vs. 2023 (nine months)
Delivered energy revenues from electric operations decreased $37.3 million, or 20.2%, compared to the nine months ended September 30, 2023 due to suppressed MISO pricing (~75% of total energy hours at the Merom Hub being priced below our production cost at our Merom Facility), reductions in demand for Power and higher demand for Gas as Gas inventories remained high with a continued decline in average spot pricing per MBtu of $2.11 compared to $2.47 during the same nine-month period in 2023.
Fuel decreased $70.5 million, or 48.0%, compared to the nine months ended September 30, 2023. Production decreased by 942 MWh, or 26.1%, from the first nine months of 2023. The decrease in fuel costs are due to the expiration of a coal purchase contract in June of 2023 and declines in coal market pricing. We used 0.5 million less tons of coal in our electric production compared to the nine months ended September 30, 2023. The average purchase price per ton of coal used in the plant on a segment basis, was $54.83 for the nine months ended September 30, 2024, decreasing from $62.37 during the nine months ended September 30, 2023. As discussed above, average spot prices for Gas were down per MMBtu decreasing the demand for Electric Power.
Cost of purchased power was $7.7 million during the first nine months of 2024. As noted above, when energy hours at the Merom Hub are priced below our production cost at our Merom Facility, we make net hourly purchases of power in the MISO market.
Other operating and maintenance costs increased $9.3 million, or 56.0%, compared to the nine months ended September 30, 2023 primarily due to our planned maintenance outage during the second quarter of 2024 which resulted in $7.0 million in additional costs for the period.
Income from operations increased $16.1 million, or 63.7%, and increased $7.23 per MWh, from the nine months ended September 30, 2023. The main drivers of this change in income from operations are described in the discussion above.
