ISO New England maintains an ongoing 10-year plan for the region to ensure the power grid will continue to meet New England’s evolving needs. The plan is built on a foundation of standards and criteria for reliability set by the ISO, Northeast Power Coordinating Council, and North American Electric Reliability Corporation. The plan is refined and finalized through an open and collaborative process with the region’s stakeholders, including generator and transmission-owning entities, as well as state representatives. Careful studies and analyses inform the plan and are also used to evaluate proposed projects initiated in response to the plan or market signals.
The Regional System Plan (RSP) is a comprehensive planning report on system needs and the resource and transmission facilities needed to maintain the reliable operation of New England’s power system over a 10-year horizon. The RSP also accounts for market efficiencies in addition to economic and environmental considerations
The CELT Report is ISO’s annual 10-year forecast of capacity, energy, loads, and transmission—a source for planning and reliability study assumptions
In accordance with Attachment K, Section 4.1(b) of the ISO’s Open-Access Transmission Tariff (OATT), the ISO performs Economic Study analyses to inform stakeholders about different future systems
The Future Grid Initiative is a key project to assess the prospective needs of the regional power system in light of state energy and environmental laws; exploring potential pathways forward to ensuring a reliable, efficient, and sustainable clean-energy grid
