This bill amends the eligibility criteria for certain thermal energy sources classified under class I renewable energy within the renewable portfolio standard. Specifically, it repeals and reenacts sections of RSA 362-F:4, I to clarify that geothermal energy, methane gas, and solar thermal energy are eligible for classification as renewable energy sources, provided that the units for useful thermal energy must have commenced operation after January 1, 2013.

The legal language that is deleted includes the previous criteria for these energy sources, which are now replaced with the new stipulation regarding the operational date. The bill aims to ensure that only newer installations of these thermal energy sources qualify under the renewable energy standards, thereby promoting the adoption of more recent technologies in the energy sector. The act is set to take effect upon its passage, which is approved for June 19, 2026.
