Levelized cost of electricity
Like most NATIONAL CITY 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 $1.05/kWh from SDG&E, reduced to $0.04/kWh from SolarPorts.
SolarPorts evaluated their interval power usage (every 15 minutes) and proposed a right-sized 115 kW solar system for on-site generation delivered as 4 SolarPort carport structures above the parking lot.
The system now produces roughly 180,634 AC kWh of clean energy each year, an estimated $76,300 in year-one utility offsets, and around $5,692,000 in net lifetime savings — turning a recurring operating-cost into a long-term, predictable energy hedge.
