Phase I - 5.7 MWdc Ground mounted Solar PV - developed, designed and managed the delivery of the 5.7 MW solar project for Graniterock. Transmission voltage Interconnection with 4 mile 60kV Tie-in. Phase II - 4 MW/8MWh BESS - engineering and interconnection study in progress.

The Overburden pile at the Quarry, where the array is located, had been in a state reclamation process so could not be utilized for other purposes. MYNT and Graniterock took advantage of two key regulatory policies: the eligibility for renewable energy projects on property in reclamation, and a CEQA exemption for renewables on minelands in reclamation. The project is the 2nd largest Behind-the-Meter solar installation in PG&E territory and represents a 60% offset of the Quarry’s annual energy demand.
