Enel X said it plans to deploy 5 megawatts (MWac) solar PV combined with 1.1 MW/2.2 MWh of battery storage for a microgrid to serve a manufacturing plant on Puerto Rico.

Under the terms of the agreement, Enel X will build, own, and operate the system on behalf of manufacturer Eaton. Enel X is part of Enel Group, an Italian multinational energy company that is active in electricity generation and distribution, as well as natural gas distribution.

Eaton will provide technology for the microgrid system, including a microgrid controller and balance of plant electrical distribution equipment. The new microgrid will enable Eaton to generate, store, and consume renewable energy, and deliver it back to the local grid while reducing stress on regional utility infrastructure. 

The solar-plus-storage microgrid project will be integrated with the facility’s existing electrical systems including onsite power generation. Microgrid control technology will balance where, when and how electricity is consumed, including during grid outages.

Earlier this year, the Puerto Rico Energy Bureau, the island’s energy regulator, released an integrated resource plan (IRP) that includes a mandate for further development of microgrids and renewable energy. It targets at least 3,500 MW of solar and more than 1,300 MW of storage by 2025.
