Tacoma Power has a full retail rate net metering policy. This is one of the best net metering structures available — you receive full retail rate credits of 10.8¢/kWh for every excess kilowatt-hour your solar system sends to the grid. This means your solar panels generate maximum value, as surplus energy produced during sunny afternoons offsets your evening and nighttime consumption at the same rate.

An 8kW solar system for a Tacoma Power customer costs approximately $21,840 before the 30% federal Investment Tax Credit. After the ITC, your net cost drops to about $15,288. This system produces enough clean energy to save you approximately $992 per year, resulting in a payback period of roughly 10.8 years.

After your system pays for itself, you'll enjoy 13+ years of dramatically reduced electricity costs. Over a 25-year period, total savings for Tacoma Power customers are estimated at $24,800 — and that's without accounting for the likely 2-3% annual increase in electricity rates that would make your savings even greater.
