The microgrid, which includes Enel X Distributed Energy Resources Optimization Software (DER.OS) and Eaton’s Power Xpert Microgrid Controller, will be one of the largest microgrids on the island, providing 13 MW of available power. The microgrid will ensure the power stays on for the manufacturer’s strategic island site, even during periods of local grid instability or damaging hurricanes.
Turnkey Solution and No-Capex Financing
The microgrid—financed, owned, and managed by Enel X—incorporates a turnkey energy storage and solar photovoltaic system that will interconnect to the site’s electrical infrastructure. The system supplements Eaton’s existing 8 MW of backup generation, and is designed to withstand Category 5 hurricanes.
Reduced Greenhouse Gas Emissions
Using its 5 MW solar array and 1.1 MW battery storage, the project is projected to reduce 4,500 MT of GHG emissions annually and provide renewable energy for over half of the site’s annual consumption.
Helping the Community
With the microgrid, Eaton will be positioned to provide excess power back to the grid, which benefits the local community and reduces demand on the island’s electric utility. In the future, Eaton and Enel X will seek opportunities to expand their clean microgrid solution across the island, helping Puerto Rico rebuild its electric grid on the bedrock of renewable and resilient energy. Already, they have teamed up to jointly develop a second microgrid at Eaton’s Las Piedras manufacturing facility.
A Model for the Future
Commenting in a Greentech Media article, Wood Mackenzie analyst Isaac Maze-Rothstein called the Puerto Rico microgrid project a “postcard from the future for islands and other centralized grid systems transitioning toward more distributed resources.”
