Net Metering in Washington State: An Overview

Blog Solarize Washington (12)


Net metering is an essential policy tool that encourages the adoption of renewable energy systems, such as solar power. For Washington State residents considering the switch to solar, understanding net metering can make the transition more economically appealing. This article provides an in-depth overview of net metering in Washington State and how it benefits solar panel users.

What is Net Metering?

Net metering is a billing arrangement that allows homeowners and businesses with solar panels to generate their electricity and sell the excess back to their utility. When your solar panels produce more electricity than your home needs, the excess power is fed back into the grid. In return, you receive a credit on your electric bill for each kilowatt-hour (kWh) of electricity delivered back to the grid.

Washington State Net Metering Policy

Under Washington State’s net metering policy, each utility is required to offer net metering until the total capacity of all net-metered systems reaches 0.5% of the utility’s peak demand. This policy applies to all utilities, including investor-owned utilities and public utility districts.

Washington State’s net metering policy allows for solar energy systems up to 100 kilowatts in size to participate, which covers virtually all residential solar installations. Importantly, the law prevents utilities from imposing any additional fees or charges on net metering customers, protecting solar customers from discriminatory rates.

Benefits of Net Metering

Net metering offers several benefits to solar panel owners. First, it provides a way to offset the costs of your solar energy system. The credits earned from feeding electricity back into the grid reduce your monthly electric bills, helping to pay off the initial investment in your solar panel system faster.

Second, net metering supports energy independence. By generating your own electricity and receiving credit for any excess, you decrease your dependence on your utility and protect against future rate increases.

Finally, net metering promotes the use of clean, renewable energy. By making solar power more economically viable, net metering encourages more households and businesses to adopt solar, reducing greenhouse gas emissions and contributing to a more sustainable energy future.


Net metering is a crucial policy that makes solar power more accessible and affordable for Washington State residents. By understanding how net metering works, homeowners can maximize the benefits of their solar energy systems and contribute to a greener, more sustainable energy future.
