Neptune Solar presents 199-MW proposal on BLM land; commissioners ask about NEPA, interconnection and reclamation
Loading...
Summary
A Hanwha Renewables representative told Millard County commissioners the Neptune Solar Energy Park would be about 199 MW on roughly 1,000 acres leased from the BLM; the developer described an interconnection agreement with Pacificorp, ongoing NEPA steps and required decommissioning bonds, while commissioners raised site, permitting and reclamation questions.
Millard County commissioners heard a presentation and questioning Thursday on a proposed solar facility called the Neptune Solar Energy Park, with the applicant identifying the project as a roughly 199-megawatt photovoltaic installation on public land managed by the Bureau of Land Management.
Robert Wilson, senior development manager with Hanwha Renewables, said the project would be sited on BLM land about eight miles west of Clear Lake near Pop Mountain Road and State Highway 257 and would tap into the Black Rock substation. He described an executed interconnection arrangement with Pacificorp (Rocky Mountain Power) and said the project’s output would be sufficient to serve the equivalent of roughly 40,000 Utah homes. Wilson said the company has completed habitat surveys, wetland delineations and cultural resource visits and is awaiting the Department of the Interior’s approval to enter NEPA scoping; the NEPA environmental-assessment process can take up to about 12 months under current rules.
Commissioners asked for clarification on site acreage (Wilson estimated roughly 1,000 acres), whether the panels would be manufactured domestically (Wilson said Hanwha has two U.S. panel manufacturing facilities in Georgia), and how generated energy is delivered into the grid. Wilson explained that once energy enters Pacificorp’s interconnection system via the Black Rock substation, it flows to the utility system and is dispatched according to market and contractual arrangements; he noted mechanisms such as corporate renewable-energy purchases or renewable energy credits exist but that the project would enter Pacificorp’s regulated market.
Planning staff and commissioners listed proposed conditions they expect to see attached to any permit: coordination for public safety and emergency response, road maintenance contributions, a site-security plan, fire prevention measures and facility reclamation requirements. Wilson said the BLM requires a decommissioning and remediation bond and that the applicant would post required bonds and generally accepts the standard conditions the county has used on previous projects. The hearing record closed with no public comments and discussion continuing on planning conditions; no county final action on the conditional-use permit was recorded in the transcript.
The county clarified this agenda item involves separate permit tracks for generation and for transmission right-of-way; both tracks will require their own review. The planning discussion will continue as staff and commissioners reconcile permit conditions with federal BLM requirements and the county’s land-use code.
