Levelized cost of electricity
Like most Vallejo businesses, the site was paying high Peak rates and large Demand charges — the kind of bill structure that punishes daytime energy use and penalizes the very hours commercial properties consume the most power. The result was a Levelized Cost Of Energy (LCOE) of $1.16/kWh from PG&E, reduced to $0.04/kWh from SolarPorts.
SolarPorts evaluated their interval power usage (every 15 minutes) and proposed a right-sized 300 kW solar system for on-site generation delivered as 10 SolarPort carport structures above the parking lot.
The system now produces roughly 564,480 AC kWh of clean energy each year, an estimated $263,300 in year-one utility offsets, and around $19,638,000 in net lifetime savings — turning a recurring operating-cost into a long-term, predictable energy hedge.
