Comprehensive Energy Strategy

Emergency Burn Ban In Effect 10/26/24 - An emergency burn ban is now in effect for all Connecticut State Parks, Forests, and Wildlife Management areas, prohibiting the use of all outdoor grills, firepits, and campfires, and the kindling and use of flame outdoors. DEEP and local agencies are working to contain several active fires across the state. Please avoid all affected State Parks and Forests, as well as the blue-blazed Mattabesett Trail. The Enduro Trail in Voluntown and portions of North Stonington within the Pachaug State Forest are closed at this time. Please note that today's forest fire danger report remains at an 'extreme' level. More information about the current fire danger, burn ban and recommended safety measures can be found here

Comprehensive Energy Strategy (CES)

The Comprehensive Energy Strategy (CES) examines future energy needs in the state and identifies opportunities to reduce costs for ratepayers, ensure reliable energy availability, and mitigate public health and environmental impacts of Connecticut's energy use, such as greenhouse gas (GHG) emissions and emissions of criteria air pollutants. Under Section 16a-3d of the Connecticut General Statutes, DEEP is charged with preparing a CES every four years. In planning for effective management of Connecticut's energy system -- including electricity, heating, cooling, and fuels used for transportation -- the CES provides recommendations for legislative and administrative actions that will aid in the achievement of interrelated environmental, economic, security, and reliability goals. Governor Lamont's Executive Order 21-3 directs DEEP to include in the next CES a set of strategies to: (1) provide for more affordable heating and cooling for Connecticut residents and businesses, (2) achieve reductions in GHG emissions from residential buildings and industrial facilities as needed to enable the state to meet the economy-wide GHG reduction targets for 2030 and 2050 established in the Global Warming Solutions Act, and (3) improve the resilience of the state's energy sector to extreme weather events, fuel commodity price spikes, and other disruptions.
