5.7 megawatts, behind the meter.
MYNT designed, engineered, and built 5.7 MW of behind-the-meter solar for GraniteRock, a century-old California construction-materials producer: one contract, in-house engineering, W-2 IBEW crews onsite through PTO.

The problem
Construction materials are energy-intensive to produce, and the load runs all day, exactly when California commercial rates and demand charges bite hardest. Buying every kilowatt-hour from the utility meant a large, rising, uncontrollable line item.
The system
5.7 MW of solar PV interconnected behind GraniteRock's own meter, so generation offsets consumption directly before a single kilowatt-hour is purchased. MYNT carried it from first-principles design through engineering, permitting, construction, and commissioning: the same team, end to end.
The result
The mechanism is solar self-consumption: onsite generation meets the daytime industrial load first, cutting purchased energy and the peaks that set demand charges. Measured first-year results publish here once verified against AMPS O&M data. We report numbers we can stand behind, not projections.
