Peru Finally Issues Key Rules for Its Reformed Electricity Market

Peru · Energy

Key Facts

— Peru has published a long-delayed regulation putting part of its 2025 electricity-reform law, Law 32249, into effect.

— The rules create a new market for grid-balancing services and, for the first time, a clear path for battery storage.

— More players can take part: power generators, grid companies, large industrial users and other firms approved by the energy ministry.

— The reform is meant to make supply more reliable and bring more solar and wind into Peru’s energy mix.

— Analysts warn that if the renewable-auction rules are badly designed, they could push electricity prices up.

Peru electricity market reform has taken a concrete step: after more than a year of waiting, the government has issued a key regulation that puts its 2025 electricity law into practice, opening the power system to battery storage and a new market for the services that keep the grid stable.

The law itself, known as Law 32249, was approved in 2025 to update rules that dated back to 2006. Its goal was to make Peru’s electricity supply more secure and reliable and to open the door to more renewable energy.

But a law needs detailed regulations before anything actually changes on the ground, and those had been stuck for more than a year. That gap has now started to close.

For foreign residents, investors and companies operating in Peru, the reform matters because it shapes how reliable the power is, how much it costs, and whether the country becomes an easier place to build solar, wind and storage projects.

What the Peru electricity market reform changes

The headline change is the creation of a market for what the industry calls “complementary” or ancillary services. In plain terms, these are the behind-the-scenes services that keep the lights steady — balancing supply and demand second by second and providing backup when output swings.

As more solar and wind come online, their output rises and falls with the weather, so this balancing becomes more valuable. The new rules set up a way to pay for it.

Crucially, the regulation also creates the conditions for energy storage — mainly large batteries — which can store power when it is plentiful and release it when it is scarce. That is the missing piece most systems need to lean harder on renewables without losing reliability.

The rules widen who can provide these services too: not just power generators, but transmission and distribution companies, large “free” industrial users, and other firms approved by the energy ministry, MINEM.

There are market mechanics as well. These balancing services will be allowed to trade in the short-term wholesale market, and energy drawn to provide them is exempted from some transmission and distribution network charges.

Separately, each distribution company will have more freedom to decide how it buys supply, including purchasing energy in blocks or buying capacity and energy separately.

Why it matters

For investors, the reform is a signal. A clear framework for storage and grid services is exactly what renewable-energy developers look for before committing capital, and Peru has struggled to modernize its power sector while attention stayed fixed on its troubled state oil company.

A functioning Peru electricity market with room for batteries and flexible services could unlock projects that had been waiting on the sidelines.

For households and businesses, the promise is a more reliable, more diversified grid. But there is a catch.

Several analysts have warned that the rules still to come — especially those governing renewable-energy auctions — could raise electricity costs if they are poorly designed. In other words, the reform’s good intentions could either lower or lift bills depending on the fine print, which is why the remaining regulations matter as much as this one.

What to watch next

This regulation is only one piece of Law 32249; more are still pending. The key things to watch are how MINEM and the regulator design the storage and auction rules, whether the changes actually translate into new projects breaking ground, and what all of it does to tariffs.

The reform lands after an Andean energy crunch earlier in 2026 exposed how fragile supply can be, giving Peru extra reason to get the details right.

What is Peru’s Law 32249?

Law 32249 is a 2025 law that reforms Peru’s electricity market, updating a framework from 2006. Its aim is to make electricity supply more secure and reliable and to bring more renewable energy into the mix. It needed detailed regulations before its changes could take effect.

What changes with the new electricity regulation?

The regulation creates a market for grid-balancing services, opens a clear path for battery storage, widens who can provide these services, and lets them trade in the short-term wholesale market with some network-charge exemptions. Distributors also gain more freedom in how they buy supply.

Will the reform raise electricity prices in Peru?

The goal is a more reliable, more diversified grid, which over time can help control costs. But some analysts warn that if the renewable-energy auction rules still to be issued are badly designed, they could push electricity prices up.

The effect will depend on the remaining regulations.

Law 32249 is Peru's 2025 electricity reform law, approved to update power sector rules that dated back to 2006. Its main goals are to make Peru's electricity supply more secure and reliable while opening the door to more renewable energy such as solar and wind.

The regulation opens the new market for grid-balancing services to a broad range of participants, including power generators, grid companies, large industrial users, and other firms approved by the energy ministry. This wider participation is a notable change from the previous framework.

Analysts warn that if the renewable-auction rules are poorly designed, they could push electricity prices higher for consumers. This concern means the details of how those auctions are structured will be closely watched by investors and businesses operating in Peru.
