Princeton Power Systems was selected by Tesla to supply power inverters for a highly innovative peak-shaving program in California. Spearheaded by SolarCity, the project involves locally storing energy from rooftop photovoltaic arrays to help offset peak demand and thus minimize demand charges. SolarCity is estimating a 20 percent reduction in demand charges, which can amount to millions of dollars annually among large commercial customers. Princeton Power Systems will provide GTIB-30s and GTIB-100s inverters.

The Princeton Power Systems inverters combined with Tesla’s lithium-ion battery technology will store locally-generated energy to supplement the grid during times of high demand. This will avoid costly spikes in energy demand in addition to providing backup power during outages.
