Net metering changes: What to do when your utility reduces credits

Why utilities are cutting net metering credits

Net metering credit reductions are driven by two forces: grid economics and utility lobbying. Where solar adoption is high, as in California, Hawaii and Arizona, the grid often has more midday solar than it needs, and utilities argue that paying full retail price for that surplus overstates what it’s worth. Utilities argue that solar homeowners still rely on the grid for backup power but pay less toward maintaining it — a claim called the “cost shift.”

California’s NEM 3.0 dropped retail-rate credits in favor of export values from the state’s Avoided Cost Calculator, which cut typical export compensation by about three quarters. As of 2026, regulators in Colorado and Oregon are reviewing their net metering rules, and Michigan, Wisconsin and Indiana have already trimmed what they pay for exports. This is not a California-only problem. Retail-rate net metering is shrinking nationwide, so for most homeowners the real questions are when it changes in their state and how much.

For existing solar owners, the immediate question is whether you’re protected and what to do next. Let’s start with grandfathering.

Are you grandfathered? How to check your net metering status

When net metering rules change, existing customers are usually allowed to stay on the old terms for years. If your system was interconnected before the policy changed, you’re likely protected — but the details matter.

In California, customers on NEM 2.0 when NEM 3.0 began in April 2023 keep their terms for 20 years from their original Permission to Operate date. In Indiana, systems interconnected before July 2022 keep full retail net metering for 30 years, one of the longest protection periods anywhere. New York lets existing net metering customers keep their terms for 20 years, while new customers are credited under VDER at roughly 80 to 90% of the retail rate depending on location.

To confirm your status:

• Find your interconnection or Permission to Operate date on your utility paperwork. This is the date that locks in your rate structure.
• Check your current utility bill to see whether your export credits still match the retail rate or have already moved to a lower avoided-cost rate.
• Review your state’s net metering docket on DSIRE or contact your utility directly to confirm grandfathering duration.

If you’re grandfathered, your credits are safe for now — but the value of storing and using your own solar just went up. If you’re not grandfathered or your utility announced a change is coming, it’s time to act.

Your first option: Add home battery storage

The single most effective response to reduced net metering credits is adding a battery to your existing solar system. California installers now pair the large majority of new solar systems with batteries — up from roughly 11% before NEM 3.0. That shift wasn’t accidental. When export credits fall from 30 cents per kWh to 5–8 cents, the value of exporting to the grid collapses. The value of storing that energy and using it during expensive evening hours skyrockets.

Under NEM 3.0, adding a battery can shorten payback by several years compared with solar alone, which is why storage often makes financial sense despite the higher upfront cost. If your utility now pays you a fraction of what you pay them, battery storage lets you stop selling low and buying high.

A few practical notes:

• Retrofitting a battery to an existing system typically costs $10,000–$18,000 before incentives, depending on capacity and brand. Homeowner-owned batteries no longer qualify for a federal tax credit, so state and utility rebates matter more. See our guide to Tesla vs SolarEdge batteries for a comparison.
• If you’re grandfathered under favorable net metering, a battery still makes sense for backup power and time-of-use arbitrage — it just may not pencil out as quickly as it does for NEM 3.0 customers.
• Check whether your utility offers VPP incentives (more on this below) before you buy — some programs reduce the upfront cost significantly.

Battery storage puts you back in control. Instead of depending on your utility to fairly compensate your exports, you consume what you produce and use the grid only as true backup.

See what incentives still apply to batteries in our guide to solar and storage tax credits in 2026.

How time-of-use rates make batteries even more valuable

Net metering changes aren’t happening in isolation. Utilities are also shifting to time-of-use (TOU) rate structures that charge dramatically different prices depending on the hour. And in some states, those changes are clearly designed to reduce solar savings and push battery adoption.

Since November 2025, Xcel Energy’s on-peak window in Colorado runs from 5 to 9 PM all year. In summer, on-peak power costs about 21.3 cents per kWh and off-peak about 7.9 cents, a gap of more than 13 cents. The timing is no accident: solar production peaks between noon and 3 PM, well before the highest rates kick in. Without a battery, your panels produce when rates are cheap and you buy from the grid when rates are expensive.

This is the same playbook California used. With a battery under NEM 3.0, you can hold onto midday solar and send it out during the evening peak, when export credits are higher. California regulators have estimated paybacks around nine years for well-managed battery systems.

If your utility recently introduced or shifted TOU rates, look at your bill closely. The rate design itself is now a policy signal: store your solar or watch your savings erode.

Virtual power plants: Get paid to support the grid with your battery

One silver lining to net metering cuts: utilities are starting to pay homeowners for battery capacity through Virtual Power Plant (VPP) programs. A virtual power plant links many home batteries so the utility can draw on them briefly when demand spikes, which eases strain on the grid.

Depending on the program, participants can earn several hundred dollars to more than $1,000 a year. Austin Energy’s Power Partner Battery Pilot, for example, pays participants an average of more than $300 a year on top of other incentives in exchange for letting the utility use stored energy during peak demand. Programs are now live or in pilot phase in California, Texas, Colorado, Vermont, Massachusetts, Arizona, and several other states.

How it works: you enroll your battery in your utility’s VPP program, and during high-demand events (usually a few dozen hours per year), the utility dispatches a portion of your stored energy to the grid. The utility schedules an event during high demand, your battery sends out part of its charge automatically, and you’re credited for taking part. Most owners never notice when an event happens.

This isn’t charity from your utility. Studies have found that home-battery VPPs can supply peak capacity for about half the net cost of utility-scale batteries or gas peaker plants, and that scaling them up nationally could save the grid billions of dollars a year. Virtual power plants are a win for the grid, a revenue stream for you, and one reason utilities may have intentionally structured rate changes to encourage battery adoption.

If you’re adding a battery, check whether your utility offers a VPP program before you sign. Some offer upfront rebates in addition to ongoing payments.

Should you resize your system or add more panels?

If your utility cut net metering credits and you haven’t installed solar yet, system sizing logic has changed. If you already have solar, adding capacity may or may not make sense depending on your grandfathering status.

Before NEM 3.0, installers typically sized systems to offset 100% of usage. Now they size for what the home will use directly plus a battery, which often means fewer panels. The old rule of thumb — size your system to produce as much as you use annually — no longer applies in net billing states. You’re better off sizing for daytime self-consumption and storing the rest.

If you’re already grandfathered under favorable net metering, adding panels can be tricky. In some states, expanding your system capacity triggers a move to the new rate structure. Maryland, for example, keeps you on your current net metering terms for the system’s life unless you expand it, sign a new interconnection agreement, replace most of the panels or take it out of service. Other states allow minor expansions without losing grandfathering, but the rules vary widely.

Before adding panels:

• Confirm with your utility whether system expansion will change your interconnection status.
• Model whether the additional production under the new (lower) export rate justifies the hardware cost.
• Consider whether adding battery capacity instead of panel capacity delivers better ROI under your current rate structure.

In most cases, if you’re grandfathered under good net metering terms, protecting that status is more valuable than expanding your array.

What if your grandfathering period is about to expire?

Grandfathering periods eventually end. When a state changes its rules, existing systems usually keep the old terms for a fixed window, commonly 10, 15 or 20 years. If your protection window is closing, you have a decision to make: accept the new lower rate or make changes that restore value.

The best time to add a battery is before your grandfathering expires. Once your export credits drop, every kWh you send to the grid becomes worth less. A battery lets you keep consuming your own power at the value you’re used to, even if the utility is no longer compensating fairly.

Once that window closes, your credits may be valued below the full retail rate, as has already happened in several states. Don’t wait until the transition happens to act. Battery prices are falling, VPP programs are expanding, and installing storage while you still have favorable net metering gives you a baseline to optimize around.

If a battery still doesn’t pencil out in your market, the next best move is consumption shifting: run major appliances during solar production hours, pre-cool or pre-heat your home in the afternoon, and charge EVs during the day. It’s not as effective as storage, but it’s free and it reduces how much you’re forced to export at unfavorable rates.

Know your rights and where to get help

Net metering policy is set at the state level, and changes go through a public process at your state’s public utility commission. If your utility has proposed changes and they haven’t been approved yet, you have a voice.

Organizations like Solar United Neighbors, state solar advocacy groups, and renewable energy coalitions track regulatory proceedings and organize public comment campaigns. In some states — Nevada and West Virginia are examples — public pressure has successfully reversed or softened proposed cuts to net metering.

If you’re unsure whether a policy change affects you, or if you need help understanding your options, find a local solar installer who can review your system, your interconnection agreement, and your utility rate schedule. A good installer will model what a battery would save you under your current and future rate structure, and help you decide whether it’s worth acting now or waiting.

You’re not powerless here. The shift away from retail net metering is real and it’s spreading, but homeowners with solar and storage are positioning themselves to benefit from the next phase of grid evolution — lower electric bills, backup power, VPP income, and freedom from rate uncertainty. The question is whether you act before or after the value of your solar drops.
