requiring capacity planning in the state 10-year energy strategy.

HB 1666 requires New Hampshire’s 10-year energy strategy to include two new elements: (1) electric capacity planning for emerging sectors like housing, transportation, technology, and data centers, with expert consultations every 3 years; and (2) analysis of demand-side measures (such as efficiency, conservation, and load management) to cost-effectively meet energy needs. The bill directly affects the state’s energy planning process and the Department of Energy, which must update the strategy accordingly. It does not provide new funding or change existing energy infrastructure requirements. The changes aim to align long-term planning with evolving energy demands without specifying new construction or operational mandates.
