Net metering in PR: what Law 10 guarantees, until when, and why it's being fought in court

If you have solar panels — or you're getting quotes — one term decides how much your investment is worth: net metering. It's the program that credits you 1-to-1 for every kilowatt-hour your system sends back to the grid: you export by day, consume at night, and pay the difference. With more than 100,000 Puerto Rican homes already on solar, net metering is the backbone of rooftop energy on the island — and right now it's in the middle of a court fight between the government and the Oversight Board. Here's what the law says, how long you're protected, and what to watch before signing a contract.

What Law 10 of 2024 guarantees

Law 10-2024 amended the original net metering statute (Law 114 of 2007) to shield the program:¹

• New customers can join net metering until at least 2030.¹⁵
• Anyone who installs on or before 2030 keeps the benefit through 2049.¹³
• The Energy Bureau can't alter the program early: any study to change it can't begin before January 2030, with public participation.¹²

In short: if you have panels or install in the coming years, the law guarantees you decades of full credit for your energy.

Why it's in court

The Fiscal Oversight Board sued to repeal Law 10, arguing it blocks the independent regulator (the Bureau) from evaluating the program on time.² On the other side, organizations like Solar United Neighbors and Ayuda Legal defend the law: without net metering, a solar system's payback stretches out by years and access closes for working families.³⁴ The solar sector estimates over 5,000 local jobs and an impact of more than $2 billion on the economy.³

While the case plays out, Law 10 remains in effect — credits keep accruing as usual.

What it means for you

• Already have panels: your net metering agreement stands; any changes (if they come) would be prospective, and the law protects installed systems through 2049.¹³
• Getting quotes: installing before 2030 locks in the long-term benefit under current law. Make sure your contract references the net metering agreement with LUMA and keep a copy.
• Read your bill: confirm exported kWh show up as credits each month; surpluses roll forward on the bill.
• Batteries: with the outages, many pair panels + battery — net metering applies to what you export; the battery covers you when the power goes out. Different things, and they complement each other.
• Watch the noise: sales pitches pressuring you with "net metering is ending now" are exaggerating — protection runs by law through 2030/2049.¹³ Sign for the numbers, not out of fear.

What's next

The Board's lawsuit continues in federal court, and the Bureau's study would wait until 2030 if the law prevails.² Any ruling that changes the rules — either way — we'll cover here in the Newsroom. Meanwhile, the sun keeps rising for free.
