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.

Additionally, the bill stipulates that the investigation will be funded through an assessment in accordance with RSA 365:37 and requires a report of findings to be submitted to the relevant Senate and House committees within one year of the bill's passage. The act is set to take effect immediately upon passage, emphasizing the urgency of the investigation into the state's energy policies and their impact on local ratepayers.
