A significant hurdle has emerged in Rockingham County's solar project, as project managers revealed unexpected requirements from Eversource that could delay the system's activation. During the Board of Commissioners meeting on May 22, 2025, Bobby O'Brien, the project manager from Revision Energy, reported that the solar array is mechanically complete and ready to operate. However, Eversource has mandated the installation of additional grounding transformers, a requirement that was previously deemed unnecessary.
O'Brien explained that the project has been in the works for over two years, with extensive testing completed on all equipment. The solar array is designed to generate electricity for county buildings, with excess power feeding back into the grid, providing financial credits to the county. Despite this readiness, Eversource's last-minute demand for grounding transformers—equipment not originally required—poses a significant challenge. O'Brien noted that this change could incur costs in the low six figures and extend the timeline for project completion by six to twelve months.
The frustration stems from the fact that Revision Energy had sought confirmation from Eversource regarding the necessity of the grounding transformers well in advance, receiving written assurance that they were not needed. This sudden reversal has raised concerns about contractual obligations and potential financial repercussions for the county, including millions in losses if the project does not go live by the required date.
Commissioners discussed the possibility of legal action against Eversource, emphasizing the importance of adhering to the interconnection agreement that governs the project. O'Brien highlighted that similar disputes are occurring statewide, with other solar developers also facing increased scrutiny and additional requirements from Eversource.
As the county navigates this unexpected setback, the urgency to resolve the issue remains high, with officials eager to activate the solar system and start realizing the anticipated savings for residents. The board is expected to consider next steps, including potential legal avenues, to address the situation with Eversource.
