Levelized cost of energy
Like most California 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 $1.15/kWh from PG&E, reduced to $0.02/kWh from SolarPorts.
SolarPorts evaluated their interval power usage (every 15 minutes) and proposed a right-sized 60.0 kW solar system for on-site generation delivered as a rooftop array on the building.
The system now produces roughly 112,896 AC kWh of clean energy each year, an estimated $52,200 in year-one utility offsets, and around $3,890,000 in net lifetime savings — turning a recurring operating-cost into a long-term, predictable energy hedge.
