This bill mandates the Department of Energy to conduct a comprehensive investigation into New Hampshire's potential withdrawal from ISO-New England, as well as other strategic decisions that could impact ratepayers in relation to New England's environmental policies. The investigation aims to ensure that New Hampshire ratepayers are not unfairly burdened by public policy initiatives from other states. The bill introduces a new section, RSA 12-P:17, which outlines specific questions the investigation must address, including the rights and obligations of ISO-New England, the implications of withdrawal on costs and reliability, and the governance of ISO-New England.

The investigation will be funded through an assessment as per RSA 365:37, and the findings must be reported to the relevant Senate and House committees within one year of the bill's passage. The bill emphasizes the need for a thorough analysis of the potential benefits and drawbacks of remaining in or exiting ISO-New England, including the development of new capabilities for state agencies and utilities, and the exploration of alternative regulatory structures to ensure reliable and affordable electricity for New Hampshire residents. The act is set to take effect immediately upon passage.
