CT HB05469

Defines "large electric load customer" as any electric customer with peak demand of at least 50 megawatts, and "colocated electric supplier" as any entity providing electricity to such customers through behind-the-meter connections or off-grid arrangements

Requires colocated electric suppliers to obtain a license from the Public Utilities Regulatory Authority (PURA) beginning July 1, 2026, and to supply 100% of the customer's anticipated load plus a reserve margin from generation sources entering service on or after July 1, 2026

Mandates electric distribution companies and municipal utilities file tariff proposals by April 1, 2027 for large electric load customers interconnecting after October 1, 2026, requiring these customers to secure dedicated generation capacity that has not previously cleared ISO-New England capacity auctions

Requires new large electric load customers to provide financial guarantees covering at least 85% of requested electric service for a minimum of 10 years, plus additional security to protect ratepayers if the project ceases operations or requires less service than anticipated

Authorizes PURA to waive generation requirements for large electric load customers who demonstrate sufficient electric demand flexibility, and directs PURA to initiate implementation proceedings by January 1, 2027
