It will be deployed in the Yabucoa Municipality of Puerto Rico, an unincorporated overseas territory of the US in the Carribbean, paired with the YFN Yabucoa Solar Project.

FlexGen said it will provide reliability and flexibility to the local grid and comply with ‘some of the most demanding grid specifications’ from the islands’ transmission system operator (TSO) Puerto Rico Electric Power Authority, using its HybridOS energy management system (EMS).

Kelcy Pegler, CEO of FlexGen, added: “Energy storage is critical to helping Puerto Rico with extreme weather and grid reliability. The island also has some of the strictest grid requirements in the world.”

Puerto Rico has been rebuilding and increasing the resiliency of its energy sector over the last few years after hurricanes in 2017 and a 2020 earthquake damaged or destroyed up to 80% of its grid infrastructure.

This includes through grid-scale solar and storage projects like ones we’ve recently reported on by EPC firm DEPCOM and IPP Genera PR as well as home battery virtual power plants (VPPs) like a 17MW scheme spreadheaded by US residential energy solutions and management firm Sunrun.

Arclight is a US-headquartered independent power producer (IPP) of primarily gas plants but has made big plans to deploy BESS technology at those sites as they are brought out of service. It launched Infinigen Renewables with a US$400 million capital commitment in 2021 to develop and operate its renewables assets, while launching a separate BESS developer Elevate last year.
