ISO-NE publishes amounts, sources of electric energy used to meet demand in 2024

ISO New England has published a breakdown of the amount of electricity produced by generators in New England and imported from other regions to satisfy all residential, commercial, and industrial customer demand from the power grid in 2024. 

Total production for the year, known as net energy for load (NEL), amounted to 116,719 gigawatt-hours (GWh), 2% higher than in 2023. 

NEL is calculated by adding total electricity generation and price-responsive demand reduction within New England to net imports from neighboring regions. The energy used to operate pumped storage power plants and battery storage units is then subtracted from that sum. Numbers are preliminary, pending the resettlement process. 

New England is historically a net importer of electricity. In 2024, however, the region imported less and exported more than usual. Net imports amounted to 10,293 GWh, down by nearly one-third from 2023. 

Output from grid-connected solar installations increased by 18% from 2023 to 2024, rising to 4,554 GWh or 4% of NEL. Wind power increased by 7% to 3,517 GWh. 

Oil-fired resources produced the same amount of electricity in both 2023 and 2024—322 GWh, which represents about 0.3% of NEL in both years. Production from coal-fired resources increased from 181 GWh to 234 GWh, accounting for 0.2% of NEL in 2024. 

The table below contains a breakdown of the resources used to meet NEL in 2024. More detailed information is available on the Resource Mix webpage. 

Energy source	Energy produced (in gigawatt-hours)	Percentage of NEL
Natural gas	59,883	51%
Nuclear	26,547	23%
Net Imports	10,293	9%
Hydro	8,221	7%
Solar	4,554	4%
Wind	3,517	3%
Refuse	2,650	2%
Wood	1,771	2%
Other	420	0.4%
Landfill gas	377	0.3%
Oil	322	0.3%
Coal	234	0.2%
Methane	33	0.03%
Price-responsive demand	10	0.01%
