Levelized cost of energy
Like most CONCORD 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 $0.03/kWh with SolarPorts.
SolarPorts evaluated their power usage and proposed a right-sized 288 kW solar system for on-site generation delivered as 8 SolarPort carport structures above the parking lot.
The system is designed to produce roughly 541,901 AC kWh of clean energy each year, an estimated $253,100 in year-one utility offsets, and around $18,879,000 in net lifetime savings — turning a recurring operating-cost into a long-term, predictable energy hedge.
