Energy (Electric Grid)

H.593 requires the Public Utility Commission (PUC) to approve any agreement the Department of Public Service (DPS) enters into for interregional electricity transmission projects. This applies when the DPS negotiates deals involving electricity transmission between regions, such as those affecting Vermont’s connections to New England’s grid. The bill aims to ensure these agreements align with Vermont’s energy policies and protect ratepayers from financial harm. The change amends Vermont law to add this PUC approval step for regional transmission agreements.

This bill requires Vermont's electric utilities and VELCO to submit a detailed report and map by 2026, identifying optimal locations for energy storage facilities and flexible energy management solutions. The report must analyze where these investments would best improve grid reliability, affordability, community resilience, and sustainability, using utility data and community health indicators. The Department of Public Service will use this plan to guide grant awards through the Clean Energy Development Board for energy storage projects. The plan must be updated every two years and will inform future climate and energy planning efforts.

This bill requires Vermont's Public Utility Commission (PUC) to create rules ensuring electric grid upgrade costs are shared fairly among all utility customers. It mandates the PUC adopt initial rules by July 2026 for cost-sharing within each utility's service area, and additional rules by July 2031 for statewide cost-sharing regardless of utility boundaries. These rules aim to distribute grid modernization expenses evenly across all ratepayers in the state. The law takes effect on July 1, 2025, directly affecting all Vermont residents and businesses paying electricity bills.
