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 1290 requires New Hampshire's Department of Energy to create rules for the installation, interconnection, and use of customer-owned energy storage systems (like home batteries). These rules will guide the Public Utilities Commission when approving utility tariffs and making decisions about customer compensation for such systems. The bill does not change existing net metering rules or electrical permit requirements for installers. It directly affects homeowners, businesses, and utilities by establishing a regulatory framework for customer energy storage. The rules must be adopted by the Department of Energy, with the Commission using them to approve tariffs and orders.
SB 540 defines "portable solar generation devices" as movable solar units under 1,200 watts that plug into standard home outlets to offset personal electricity use. The bill exempts these devices from utility interconnection rules and net metering requirements, while requiring safety standards like anti-islanding protection (UL 1741/IEEE 1547) and compliance with building codes. Electric utilities cannot demand approval, fees, or extra equipment for compliant devices, and the bill limits utility liability for customer-installed devices. This directly affects homeowners using small portable solar systems, simplifying their installation without utility oversight.
HB 1724 requires New Hampshire electric utilities to submit annual public reports detailing transmission costs, wholesale electricity market impacts, capacity market auctions, and generation resource adequacy. These reports must include project-specific transmission cost breakdowns, wholesale purchase strategies, capacity auction results, and specific analyses of data center interconnection costs (for facilities 5+ MW). Utilities must also propose how ratepayers will be protected from costs if data centers fail or withdraw, with reports due annually starting January 1, 2027. The New Hampshire Public Utilities Commission will hold public hearings every three years to review these filings.
SB 518 streamlines approval for specific electric transmission line upgrades by creating a "qualified transmission asset replacement project" category. It applies to utility companies replacing 5% or more poles/towers on existing lines within 5 years without increasing pole height, tower width, or corridor size. The bill requires applications to include detailed project descriptions, financial plans, and public notices, while giving the energy department automatic party status in reviews. This modifies the site evaluation process to expedite projects meeting strict criteria, directly affecting utilities planning eligible transmission line replacements in New Hampshire.
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.
