The Puerto Rican Solar Business Accelerator will work with two Puerto Rico communities to develop microgrid projects using solar energy and battery storage.

Microgrids use solar energy and battery storage to provide a sustainable, local electricity source independent of the power grid. They support local resilience in areas that are especially vulnerable to the impacts of natural disasters.

These upcoming projects aim to serve as models for designing, installing, and managing microgrids in Puerto Rico. Technical and administrative assistance will be provided by IREC, along with our partners at the Microgrid Laboratory at the University of Puerto Rico, Mayagüez.

Request for Proposals: Microgrid Project in Castañer, Puerto Rico

In partnership with the Cooperativa Hidroeléctrica de Montaña, IREC is seeking responses to this Request for Proposals for a community microgrid project in Castañer, Puerto Rico. The project will include approximately 225 kW in solar PV and 500 kWh in storage. The deadline for responses is September 29, 2021.

About this Project

The solar energy microgrid project will be located in the rural community of Castañer, located in the Cordillera Central in Puerto Rico. This community experienced more than six months of without electricity following Hurricane Maria in 2017. More than three years later, it continues to face many challenges due to a fragile, insecure, and intermittent electrical system.

This microgrid will provide solar PV and energy storage that will power essential community services and allow for enhanced resilience in the face of natural disasters. We hope this project will serve as a model for other community resilience initiatives in Puerto Rico and throughout the United States.

Key Dates

The project team will hold a pre-proposal conference for interested parties on September 15 and conduct a site tour on September 17. Questions on the proposal are due on September 21, and the deadline for submission is September 29.

If you have questions about the RFP, contact [email protected]. If you would like to register for the Pre-bid conference on September 15, send a request to [email protected].

Castañer was chosen from a total of nine candidates following a rigorous selection process. We are now in the process of selecting a second Puerto Rico community to develop a microgrid project.
