SB 468 allows alternative treatment centers (ATCs) that provide medical cannabis to apply for permission to operate greenhouse cultivation facilities, which typically use less energy than indoor growing. ATCs must submit a detailed plan showing how greenhouse cultivation will lower energy costs and reduce prices for registered qualifying patients. The state department must create rules for greenhouse operations - including security, location, and compliance with local zoning - and seek input from patients, caregivers, and community residents before approving new sites. ATCs will also report annually on greenhouse impacts to energy costs and product prices as part of their required state filings.

HB 1002 repeals the property tax exemption for solar energy systems, meaning homeowners and businesses with solar installations will no longer be excluded from taxable property assessments. The bill removes specific tax code provisions (RSA 72:62 and related sections) that previously allowed solar systems to be valued separately for tax purposes. Starting April 1, 2027, solar energy systems will be included in standard property tax valuations, requiring owners to pay taxes on these systems as part of their property assessment. This change directly affects property owners who currently benefit from the exemption, shifting their tax obligation to align with standard property valuation practices.

SB 449 requires commercial or industrial entities with solar or wind systems between 1 and 5 megawatts (called "industrial hosts") to consume at least 33% of their own electricity generation annually. This applies to new systems installed after January 1, 2027, that participate in net metering. The rule does not apply to low-income customers as defined by utility regulations. The bill modifies New Hampshire's net metering rules to ensure larger systems primarily offset their own electricity use, rather than exporting excess power.
