According to the Projections from ISO New England, the region's solar capacity is set to nearly double within the next 10 years.

ISO New England anticipates substantial growth in distributed PV nameplate capacity, projecting an increase from 7,345 MW in 2024 to 13,466 MW by 2033. This growth includes a doubling of BTM PV capacity, expected to rise from approximately 4,000 MW to 8,000 MW.
In 2024, BTM PV output is forecasted to reach 5,444 gigawatt-hours (GWh). Without BTM PV, the region's projected energy usage for the year would be nearly 5% higher, totaling 119,179 GWh. Additionally, BTM PV is expected to reduce the summer system peak electricity demand by about 4%, bringing it down to 24,553 MW.

By 2033, the last year of the forecast period, BTM PV is projected to lower summer peak demand by a similar percentage, to 27,052 MW. In that year, the region's anticipated energy usage is expected to reach 140,000 GWh, approximately 7% higher than it would be without BTM PV installations.
