ISO-NE has published its annual CELT, energy efficiency, and PV forecasts
ISO New England has published its 2016-2025 Forecast Report of Capacity, Energy, Loads, and Transmission (CELT), a primary source for assumptions used in ISO system planning and reliability studies. It provides a 10-year snapshot of the New England power system, including the total generating capacity of resources in the region, the breakdown of the region’s generators by fuel type, a link to the list of transmission projects proposed, planned, and under construction to ensure system reliability, and the long-term forecast for growth in energy use and peak demand. ISO New England’s long-term forecast for electricity use is developed each year using state and regional economic forecasts, 40 years of weather history in New England, and other factors. The CELT also includes results from the ISO’s latest energy-efficiency (EE) forecast and solar photovoltaic (PV) forecast, which project the load-reducing effects of EE resources and “behind-the-meter” PV resources connected at customer sites to local distribution systems.
