Maryland Net Metering 2026: What the Utility RELIEF Act Means for Your Solar Decision

Maryland homeowners with solar, or seriously considering it, need to understand one law passed this year. The Utility RELIEF Act (House Bill 1532) ends full net energy metering (NEM) in the state and sets a binding deadline for when that change takes effect. What you do before that date determines the solar credit rate you live with for the next 25 to 30 years.

The Utility RELIEF Act (HB 1532) Changes the Deal

HB 1532 eliminates full 1:1 net metering in Maryland. Under the current system, homeowners who send excess solar power to the grid receive a credit equal to the full retail rate of that electricity. Under the new law, that credit will drop below the full retail rate. The exact figure hasn’t been finalized. The Maryland Public Service Commission (PSC) will set the rate by February 1, 2027, but it will be meaningfully less than full value.

Two conditions can trigger the change:

• The statewide deadline of July 1, 2027
• Maryland reaching 3 gigawatts (GW) of installed solar capacity statewide, whichever comes first

Maryland is the first East Coast state to set a firm timeline for ending 1:1 net metering. California and Nevada have already made this move, and homeowners in both states now receive reduced credits on the power they produce.

The law also drew support from a grid equity argument. Proponents contend that when solar owners receive full retail credit for excess power, the costs of maintaining the grid shift onto non-solar customers, placing an undue burden on lower-income households who can’t afford installations. It’s an argument that carried political weight during the bill’s passage.

The research, however, tells a more complicated story. 

A 2025 NREL study found the monthly bill impact on non-solar customers is less than $1 in states where residential solar penetration is at or below 3% of households. The same study found that nine of the 12 states that revised net metering did so at or below that threshold, when potential rate impacts were likely under $1/month, and that many states have retained net metering at substantially higher penetration levels without revising it. 

NREL’s conclusion was that no clear, consistent link exists between the potential rate impacts of net metering and the timing of state revisions.

For homeowners who go solar after the new NEM laws take effect, the impact runs in the opposite direction. When export credits drop, the value of every kilowatt-hour sent back to the grid drops with it. Payback periods lengthen, and the lifetime return on a system installed after the revision is substantially lower than for one grandfathered under the prior rate. 

California’s shift to NEM 3.0 illustrated this directly. Solar installations fell sharply in the months that followed as the economics changed for new customers

What Maryland Net Metering Actually Does for You

Net energy metering is the billing arrangement that makes rooftop solar financially viable for most homeowners. When your panels produce more electricity than your home uses, the excess flows to the grid. Your utility tracks that surplus and credits it against the power you draw from the grid when your panels aren’t producing enough, including at night, on cloudy days, or during periods of high demand.

Under Maryland’s current full NEM policy, that credit equals the full retail electricity rate. Send $1 worth of power to the grid, get $1 off your bill. Over a system life of 25 to 30 years, that relationship between production and savings is what makes solar a sound long-term investment for Maryland homeowners. When that credit rate drops, the math on your system’s return changes with it.

Where Do You Stand? It Depends on One Thing

Your situation under HB 1532 depends entirely on when your system is installed and approved relative to the deadline.

If you’re in the second row, the rest of this post is written for you.

The Grandfathering Clause Is the Exception, Not the Rule

No other state that has reduced net metering has offered homeowners a full grandfathering protection of this kind. When California moved to NEM 3.0, existing solar owners kept their rates, but the transition happened faster and with far less runway for new installations to qualify. Maryland’s law gives homeowners a defined window with a guaranteed outcome for those who act within it.

Install before the deadline, and your system locks in the current 1:1 credit rate for its entire operating life of 25 to 30 years or more. That’s not a promotional offer from a solar company. It’s written into state law.

The protection is real, but the window is finite. Once the July 2027 deadline passes, or once Maryland hits the 3 GW cap (whichever comes first), new solar installations get the reduced NEM 2.0 rate, and there is no retroactive path back to 1:1.

The Hidden Risk of Waiting Until 2027 

The calendar date in the law is July 1, 2027, but the practical deadline for most homeowners is earlier.

Going solar is not a same-week transaction. From the day you sign a contract to the day your system receives Permission to Operate (PTO), the utility approval that officially activates your system and starts your net metering credits, the process takes two to three months on average, and sometimes longer. That timeline covers system design, permitting, installation, utility interconnection review, and final inspection.

A homeowner who waits until spring 2027 to start the process may not receive PTO before the deadline.

The 3 GW cap adds a second layer of risk. Maryland’s solar capacity has grown steadily, and there is no public countdown for when the cap will be reached. If it hits before July 2027, the policy change kicks in immediately with no grace period for installations already underway.

What Happens If You Wait

Homeowners who go solar after the deadline receive the NEM 2.0 rate determined by the PSC. The exact rate hasn’t been set yet, but the law’s framework makes clear it will be below the current retail-rate credit.

The financial impact compounds over time. At full 1:1 credit, a properly sized system can offset a substantial portion of your annual electricity bill. At a reduced rate, the same system produces less bill offset, extends the payback period, and delivers a lower return over its lifetime. The panels don’t change, but the rate they earn does.

This Isn’t Just a Maryland Problem

Maryland net metering 2026 reflects a national trend, not a local anomaly.

As solar adoption has grown, utilities have faced increasing pressure on their traditional revenue model. The more customers generate their own electricity and receive full retail credit for the surplus, the less electricity utilities sell, and the harder it becomes to recover fixed grid maintenance costs through standard volumetric rates. 

That financial pressure is a significant driver behind NEM changes nationwide, and it exists independently of any one state’s policy debate.

California eliminated full 1:1 net metering when its NEM 3.0 policy took effect in 2023. Homeowners who installed solar after that date saw payback periods increase substantially compared to those who locked in earlier rates. Nevada made a similar move and faced significant backlash, but the reduced rate was not reversed. North Carolina is showing early signs of following the same path.

Maryland is the first East Coast state to set a binding deadline, but the policy pressures driving these decisions (grid cost equity, utility revenue concerns, and shifting state energy priorities) exist everywhere. Other East Coast states are likely to follow. Homeowners who act now lock in the same rate that every existing Maryland solar owner already has. That window exists here because Maryland put it in writing. It won’t exist everywhere that follows.

The Window Is Still Open, But the Timeline Is Tight

If you’ve been weighing the decision to go solar, the Maryland net metering deadline gives you a concrete reason to move now rather than later. The 1:1 rate that existing solar owners locked in years ago is still available to you, but only if your system receives PTO before the July 2027 deadline or the 3 GW cap is reached, whichever comes first.
