Washington Net Metering Laws & Utility Buyback Explained

SBI Editorial DeskUpdated Q1 · 20262 sections

Washington mandates robust 1:1 retail net metering policies that protect homeowners. If you use major utilities like PSE or Avista, understanding the net metering true-up cycle is vital to maximizing your savings.

01

How 1:1 Retail Net Metering Works

During the incredibly long, bright summer days of the Pacific Northwest, your system will generate significantly more power than your home can consume. This excess electricity flows backwards into the local grid. Your utility company is required by law to credit your account for this power at the full 1:1 retail rate.

02

The March 31st True-Up Cycle

You bank these summer credits to offset your energy consumption during the shorter, rainier winter months. Washington operates on an annualized net metering cycle that concludes on March 31st every year, ensuring you have the entire dark winter to drain the massive bank of credits you generated in July and August.
