This bill amends the eligibility criteria for certain thermal energy sources classified under 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 generating useful thermal energy began operation after January 1, 2013. The previous language regarding these energy sources has been deleted and replaced with the new criteria.

The bill aims to ensure that only newer installations of these thermal energy sources qualify under the renewable energy classes, thereby promoting the adoption of more recent technologies. The effective date of the act is upon its passage, allowing for immediate implementation of these clarifications in the law.
