Regional Electricity Outlook

The Power of Change.

New England’s electricity industry is always moving forward. The 2021 Regional Electricity Outlook (REO) follows a “Then – Now – When” chronology, presenting an overview of this momentum, which began in the mid-1990s when industry and policymakers sought to restructure the region’s wholesale electricity sector and created ISO New England. A unique partnership emerged, propelling change and moving the industry from THEN to NOW.

Follow our timeline and read how WHEN we reach our clean energy future, it will be the tangible result of this collaboration and commitment among the ISO and its stakeholders in achieving a clean, reliable, and cost-effective power system for New England.

See where the region’s electricity industry is going in this year’s Regional Electricity Outlook.
