Solar Panel Installation in SnoPUD Territory

Net Metering with SnoPUD

Washington state’s net metering policy enables customers who generate electricity to offset their annual consumption. If a customer’s energy production exceeds their consumption in a billing period, they accrue credit in a net metering reserve. However, if their consumption surpasses production, they must pay the Public Utility District (PUD) for their net purchase. It’s important to note that all PUD customers are subject to a minimum energy charge, which cannot be offset by solar energy. The net metering reserve allows customers to carry forward their credit and apply it to future energy charges. However, according to state law, net metering reserve credit expires on March 31 each year. The PUD does not compensate for excess generation, and customers cannot transfer their surplus energy to other PUD customers. To optimize benefits, it is recommended that customers size their photovoltaic (PV) systems to match their average annual energy consumption.
