Only one day after the Chicago City Council approved Mayor Rahm Emanuel’s plan to move the city to 100% renewable energy by 2035, Puerto Rico has followed suit with Governor Ricardo Rosselló signing PS 1121, which sets a 100% by 2050 renewable electricity mandate for the island.
Rosselló’s signature is hardly surprising, given that he was a vocal supporter of the call to entirely decarbonize the island’s electricity supply using renewable energy. And according to P.J. Wilson, the president of the Solar + Energy Storage Association of Puerto Rico (SESA-PR), this is just the beginning.
“We have to begin this very long and very tedious process of implementation of all the things in the bill,” Wilson told pv magazine. This includes “having the dialogue with PREPA to ask them to implement the laws right away, in the way that we want them to.”
Some of these details in PS 1121 include:
- banning coal plants starting in 2028
- instituting a maximum 90-day utility approval period for commercial and industrial solar projects (from 25 kW and 5 MW)
- establishing automatic interconnection to the grid for residential solar systems under 25 kW
- exempting energy storage systems from sales taxes
The push for gas
The signing of the 100% renewable energy law comes as the U.S. Department of Energy is calling for the island to deploy more natural gas infrastructure. According to UtilityDive, this week DOE Assistant Secretary Bruce Walker argued before a U.S. House Committee that 1200 to 1600 MW of natural gas could “greatly enhance the reliability and disaster resilience of Puerto Rico’s power system”.
The fact that the vast majority of power outages are caused by power lines going down makes such statements questionable, and the Trump DOE may be instead speaking to its own interest in expanding markets for domestic gas production.
Nor is DOE the only party that is looking to lock in gas infrastructure on the island; as previously reported by IEEFA the island’s utility has signed contracts with Miami’s New Fortress Energy to convert its San Juan power plant from petroleum to natural gas and to build a new liquefied natural gas (LNG) import facility.
Gas + solar vs. coal and oil
But while DOE Assistant Secretary Walker has said that his plans “could be at odds” with the 100% renewable energy law, SESA-PR’s Wilson does not see it that way.
“This is not our fight,” states Wilson. “We are not a group that is fighting for or against natural gas expansion.”
One of the reasons is the very large volume of solar that needs to be put online to meet even the interim goals of PS 1121, which includes moving to 40% renewable electricity by 2025. This is up from an estimated 2% in the fiscal year ending in mid-2017 – a 20x increase, assuming no increase in electricity demand.
Wilson also notes that the island still gets 17% of its electricity from coal, as well as 47% from petroleum. As such there is plenty of room for gas to replace oil and coal without competing against the deployment of renewables.
In this if nowhere else, there may be no conflict between SESA-PR and PREPA’s goals. Wilson notes that PREPA CEO José Ortiz’ stated goal is to transform the island’s electricity system to 60% gas and 40% renewable energy.
“Our part is the 40%,” states Wilson.
Opportunities for solar + storage
Residential solar companies clearly see this as a massive opportunity. Sunrun notes that the law is clear that all scales of renewable energy production, including rooftop solar, will qualify for renewable energy credits.
“Embracing technology like home solar and batteries will play a critical role in accomplishing these trailblazing goals, putting the people of Puerto Rico at the center of the solution with local jobs and clean, resilient, reliable, energy for homes across the island,” reads a statement by Lynn Jurich, president and CEO of Sunrun.

Renewable energy is great for the environment until those batteries need to be replaced and then we’ll be polluting the earth full of batteries with chemicals inside them..
Chemicals is an extremely broad term. Lithium ion batteries are far less toxic than lead acid batteries, and are likely to be re-used as the materials in them are valuable. Furthermore, we can always mandate that batteries be recycled if the market doesn’t take care of it.
What a lame excuse for not going to renewables! As Christian Roselund said there is something such as recycling! Lead acid car batterise have been recyled for years.
With Trump turning the EPA Environmental “Protection” Agency into the Environmental “Pollution” Agency what about the door he has opened for almost every type of pollution possible!
What from burning coal is recyclable? That goes directly into the atmosphere! I expect you do not believe in Global Warming either.
And what about the spent fuel cells from nuclear that we really have not found an absolutely safe way to transport or more importantly store for how long of a half-life?
This is a rosello JOKE1 This government believes that gas is renewable energy. They are changing from oil to gas in 5 or 6 plants. We will have gas for the next 40 years, instead of going directly to solar. I have solar energy at home since 1999.
Hello Mr. Marty,
You’ve made this comment repeatedly.
While I would also like to see the most rapid transition to renewable energy possible, I want to note that according to U.S. Department of Energy statistics Puerto Rico got 3% of its power from renewable energy in 2017. Given how far renewables have to go, I personally agree with P.J. Wilson that the switching of oil-fired plants to gas is not something that interferes with a rapid transition.
Instead, Puerto Rico will have its work cut out for it growing renewable energy generation 13x in only six years to meet the 40% by 2025 target in the legislation.
