(HARTFORD) – The Connecticut Department of Energy and Environmental Protection (DEEP) today joined eight other Northeast and Mid-Atlantic states in issuing a Request for Information (RFI) seeking interregional transmission project concepts that would improve grid reliability, support economic growth, and reduce costs for consumers. The RFI was issued by the bipartisan Northeast States Collaborative on Interregional Transmission, a group formed in 2023 to fill a gap in today’s interregional transmission planning processes. Through this collaboration, DEEP is working to unlock reliability benefits and cost savings for the state’s ratepayers.

DEEP Invites You to Celebrate Spring Fishing Day on Saturday April 12
(HARTFORD) — Connecticut’s Department of Energy and Environmental Protection (DEEP) invites all residents and their families to celebrate Spring Fishing Day this Saturday, April 12. Every spring, the second Saturday in April is the start of the “catch and keep” season for trout. Starting at 6:00 a.m. on April 12, anglers are allowed to keep the trout they catch, though the permissible numbers and size of fish that can be kept varies by waterbody. While trout fishing is open year-round, it is “catch and release” fishing only from March 1 until 6:00 a.m. on April 12 on most waterways in the state (the exceptions are Trout Management Lakes, Sea-Run Trout Streams, and waters designated as “Tidal Waters and Tributaries”).
ADVISORY-DEEP Lowers Caution Issued for CT River Users Following East Windsor Sewer Line Repair
(HARTFORD)—The Connecticut Department of Energy and Environmental Protection (DEEP) is updating its advisory related to the sanitary sewer break that occurred in East Windsor.
(HARTFORD)— Burning wood to keep a home warm is a long-standing tradition in New England, and we still expect to have a few more cold days before spring truly arrives. Depending on the source of the wood, wood burning can provide a cost-effective alternative to use of fossil fuels. This practice does produce indoor and outdoor emissions harmful to human health, however, which is why the Connecticut Department of Energy and Environmental Protection (DEEP) is urging residents to protect their health and that of their family, friends, and neighbors by employing “best burn” practices. Properly burning the correct type of wood limits exposure to wood smoke, which is a toxic air pollutant.
(HARTFORD) — Does hiking, walking, and immersing yourself in the sights, sounds, and fresh air of the spring season sound like something you would like to do with friends, family, four-legged friend(s), and co-workers? If so, it's time to take on the Connecticut Department of Energy & Environmental Protection’s (DEEP) 2025 Sky’s the Limit Hiking and Walking Challenge!
