Energy usage will decline slightly and peak demand will remain flat over the next 10 years

On May 1, 2017, ISO New England published the 2017-2026 Forecast Report of Capacity, Energy, Loads, and Transmission (CELT). The report is a primary source for assumptions used in ISO system planning and reliability studies. It provides a snapshot of the New England power system, including:

The long-term forecast for electricity use is developed each year using state and regional economic forecasts, 40 years of weather history in New England, results of both the ISO’s energy-efficiency (EE) forecast and solar photovoltaic (PV) forecast, and other factors. The ISO calculates a gross forecast and then applies the EE and PV forecasts to develop a net forecast.

The 2017 CELT projects that energy usage will decline slightly in New England and peak demand will remain flat over the 10-year period. The primary factors are continuing robust installation of energy-efficiency measures and behind-the-meter solar arrays throughout the region, as well as a slightly lower forecast for economic growth in New England.

2016 energy and demand

Looking back at 2016, actual energy usage dropped 2.0%, from 126,955 GWh in 2015 to 124,382 GWh last year.

In 2016, actual demand peaked at 25,596 MW on August 12, 2016. Without the energy-efficiency measures installed in New England, as well as reductions by demand-response resources, price-responsive demand-side resources, and behind-the-meter solar resources, the peak would have come in at about 28,504 MW.
