Washington Net Metering: What Solar Customers Need to Know About Potential Changes

If you’re thinking about installing solar in Washington, you may have questions about the future of net metering. Net metering allows homeowners to receive credits for excess electricity their solar systems send to the grid, helping make solar a more affordable investment.

But net metering policies are facing growing scrutiny as Washington utilities evaluate how they compensate customers for exported solar energy. Recent utility proposals and the completion of a statewide study examining the value of solar and battery storage have brought these questions into sharper focus.

What does this mean for Washington homeowners? No statewide end to net metering has been announced as a result of the study, and the timing and nature of any future changes remain uncertain. However, homeowners should not assume today’s net metering benefits will remain available indefinitely.

This is particularly important for customers of Puget Sound Energy (PSE) and PacifiCorp, where developments involving net metering deserve close attention.

Why Is Washington Net Metering Under Discussion?

Net metering helps homeowners get more value from their solar systems by crediting them for excess electricity sent to the grid. Those credits can help offset electricity purchased from the utility when their solar panels aren’t producing enough power to meet their needs.

As Washington utilities approach the limits established under state net metering law, questions about compensation for exported electricity are becoming increasingly important.

Some utilities and other critics argue that the credits solar customers receive can exceed the costs utilities avoid when customers generate their own electricity. They contend this creates a cost shift to customers without solar.

Solar advocates counter that these arguments may overlook important benefits of distributed solar, including electricity generation, potential reductions in grid infrastructure costs, environmental benefits, and greater energy resilience when solar is paired with battery storage.

How these costs and benefits are evaluated can influence decisions about what utilities pay—or credit—customers for their exported electricity.

Washington’s Value of Solar and Storage Study Is Complete

To help inform these discussions, the Washington State Legislature commissioned a Value of Solar and Storage (VOSS) study. Conducted by the Washington State Academy of Sciences, the study examined the benefits and costs of distributed solar and energy storage systems, bringing together research and perspectives from utilities, solar industry representatives, and technical experts.

The study considered a range of factors relevant to determining solar’s overall value, including:

• Electricity generation: The value of the energy solar systems produce and deliver to the grid.
• Grid infrastructure: Potential effects on transmission and distribution system costs and operations.
• Environmental benefits: Reductions in greenhouse gas emissions and other pollution.
• Energy resilience: The role of solar and battery storage in supporting reliable power.
• Economic impacts: Effects on consumers, jobs, and Washington’s economy.

With the VOSS study now complete, policymakers and utilities have additional information to consider as they evaluate the future of net metering in Washington.

However, completing the study does not automatically change net metering rules, establish a timeline for changes, or mean that a statewide end to net metering is coming. What happens next will depend on decisions by utilities, regulators, and policymakers.

For homeowners, the important takeaway is that discussions about the future of net metering are continuing, and the policies available to new solar customers could change.

Is Net Metering Ending in Washington?

Net metering has not been eliminated statewide, but its future is uncertain.

Washington’s utilities operate under different circumstances, and their net metering programs may not all change at the same time or in the same way.

Under Washington law, utilities subject to the state’s net metering requirements must continue offering net metering until they reach the applicable statutory limit. Once a utility reaches that limit, the compensation arrangements for new solar customers become an important policy question.

Some utilities may continue existing compensation arrangements, while others may pursue changes to how customers are credited for electricity they send to the grid.

PacifiCorp has already filed for significant changes to net metering compensation, illustrating that these discussions can lead to concrete proposals. PSE customers should also pay attention to developments affecting their utility.

The completion of the VOSS study is one important development in this broader discussion. But it does not tell us exactly what will happen next, which utilities may change their policies, or when any changes might take effect.

Why PSE and PacifiCorp Customers Should Pay Attention

If you receive electricity from Puget Sound Energy or PacifiCorp, it’s worth paying particular attention to developments involving net metering.

Utility-specific proposals and regulatory decisions can affect the financial benefits available to future solar customers. Compensation arrangements that are available today may not necessarily be the same arrangements offered to customers who install solar in the future.

This doesn’t mean you need to rush into a decision that isn’t right for your home or budget. Solar is a significant investment, and it’s important to choose a system that fits your energy needs and financial goals.

However, waiting indefinitely while assuming today’s net metering benefits will always be available could be a costly assumption.

If you’re considering solar, now is a sensible time to understand your utility’s current policies, evaluate the potential benefits of installing a system, and consider how future policy changes could affect your investment.

Solar can offer benefits beyond net metering, too. A properly designed system can reduce your reliance on utility electricity, while battery storage can provide backup power during outages when configured appropriately.

The right solution depends on your electricity consumption, property, utility rates, and goals.

Is Now a Good Time to Go Solar in Washington?

For many Washington homeowners, solar can still be a worthwhile investment. But the financial calculation depends on more than the price of solar panels. Utility rates, electricity consumption, system design, net metering credits, and the availability of battery storage all play a role.

With the VOSS study complete and future policy decisions still uncertain, now is a sensible time to evaluate your options rather than assume current net metering arrangements will last indefinitely.

At Fire Mountain Solar, we design and install residential solar systems throughout Washington State, including grid-tied solar, solar and battery systems, whole-home backup power, and off-grid systems. We work with homeowners to develop systems suited to their properties, energy needs, and goals.

Whether you’re interested in reducing your electricity bills, adding backup power, or exploring an off-grid system, we can help you understand your options and determine what makes sense for your home.

I Already Have Solar. Could My Net Metering Benefits Change?

If you already have a grid-connected solar system, the effect of future policy changes will depend on the rules and terms that apply to your utility and your system.

Existing customers may receive different treatment from customers who install solar after a policy change. However, you should not assume that every utility will offer the same protections or that current compensation arrangements are guaranteed to remain unchanged indefinitely.

Pay attention to official communications from your utility and regulatory decisions that specifically address existing solar customers.

If you’re considering adding solar panels or battery storage to an existing system, check how any proposed changes could affect your circumstances before proceeding.
