What the filing saysHB 5469 requires both Connecticut EDCs to create a large electric load customer tariff for interconnections after October 1, 2026, with financial guarantees covering at least 85% of requested service for a minimum of 10 years. PURA must open an implementation proceeding by January 1, 2027 -- the statewide mandate is enacted, but neither utility's own specific tariff filing was confirmed as filed during this research.
