Energy (Electric Grid)

SB 111 establishes a pilot program allowing New Hampshire electric utilities to buy reliability indexing credits from qualified local energy storage systems (like batteries) to support grid reliability. The program would pay storage providers the difference between a set "strike price" and a daily "reference price" reflecting wholesale market value - paying them when the strike price is higher, and charging them when the reference price is higher. Utilities must get approval from the Public Utilities Commission for multi-year agreements (up to 200 megawatts) and recover costs through customer rates. The Department of Energy must develop program terms by December 2025, with utilities petitioning for approval by February 2026. This pilot aims to incentivize storage participation without direct state funding.

SB 589 requires New Hampshire to create a task force studying electricity needs for interstate trucking charging stations, port electrification, and transmission corridors, with a report due by June 2027. It authorizes a pilot program for microgrid development at up to five locations to improve energy resilience, collaborating with utilities and businesses. The bill also mandates the Department of Energy to develop cybersecurity guidelines for distributed energy systems like solar and battery storage. These provisions directly affect state agencies, transportation infrastructure planners, port operators, and energy providers by setting new planning and safety requirements.

HB 1739 creates incentives to attract large data-center campuses to New Hampshire while modernizing the electric grid. It offers developers phased property tax breaks over 12 years and transferable tax credits covering up to 20% of construction costs, contingent on signing binding Grid Modernization Agreements. These agreements require developers to source non-gas electricity (like solar or wind) matching their energy use, fund grid-stabilizing programs, and partner with community colleges for workforce training in data-center operations. The bill also establishes fast-track permitting for eligible sites and mandates community benefits like noise limits, environmental screening, and resident bill credits from exported power.

HB 1741 requires New Hampshire electric utilities to create programs that coordinate customer-owned distributed energy resources (DERs) like solar panels, batteries, and smart thermostats to support the grid. Utilities must file proposals with the Public Utilities Commission for enrollment programs offering upfront payments and performance-based payments during grid events, with special incentives for low-income customers. The bill establishes rules for aggregators (third-party coordinators) and direct customer participation, including payment structures, equipment requirements, and restrictions on penalties. It aims to reduce peak demand, lower costs for ratepayers, and improve grid reliability by integrating existing DERs into utility-managed systems.

SB 597 caps annual electric utility rate increases at 4% above inflation, preventing excessive hikes for New Hampshire residents. It requires the Public Utilities Commission to develop performance-based incentives tied to specific metrics like service reliability, customer satisfaction, grid modernization, and reducing peak demand. The Commission must complete an initial review within one year to establish these incentives and update them every four years. This bill directly affects electric utilities and their customers in New Hampshire, where high utility costs have been a longstanding concern.

HB 1723 requires all electric utilities and grid operators in New Hampshire to assess and report vulnerabilities of high-voltage transformers (100 kV+ and 25 MVA+) to geomagnetic disturbances (like solar storms) and electromagnetic pulses. By January 2027, covered entities must conduct technical assessments using specific international standards, evaluating risks like transformer saturation and insulation damage. They must then submit detailed reports to state agencies by 180 days after enactment, including transformer specifications, manufacturing origins, and recommended protection measures. This aims to safeguard critical grid infrastructure from potential widespread power outages caused by natural or man-made electromagnetic events.
