DEEP: Integrated Resource Planning

Integrated Resource Plan
Connecticut General Statutes section 16a-3a requires that the Department of Energy and Environmental Protection (DEEP) prepare an Integrated Resource Plan every two years. An Integrated Resource Plan (IRP) is comprised of an assessment of the future electric needs and a plan to meet those future needs.  It is “integrated” in that it looks at both demand side (conservation, energy efficiency, etc.) resources as well as the more traditional supply side (generation/power plants, transmission lines, etc.) resources in making its recommendations on how best to meet future electric energy needs in the state.
2018 IRP
On May 29, 2018, DEEP released a Notice of Proceeding, Scoping Meeting, and Opportunity for Public Comment for the 2018 Integrated Resources Plan. DEEP will conduct a scoping meeting on June 12, 2018 and is accepting public comment on the 2018 IRP scope until July 12, 2018. The proposed scope of the 2018 IRP includes the following topics: 
• Background and Purpose of the IRP
• Updates Since the 2014 IRP
• Forecast of Resource Adequacy
• Fuel Security
• Global Warming Solutions Act
• Zero Carbon and Renewable Generation
