Microgrid solution sought for Puerto Rico’s Roosey Roads

By on May 10, 2018

SAN JUAN – The Local Redevelopment Authority for Naval Station Roosevelt Roads in Puerto Rico has issued a request for proposals (RFP) to manage the electrical distribution system at the former military base and operate an independent microgrid “as an electric service company” to supply the power needed by the premises’ 15 current and future tenants.

The selected energy distribution or generation providers would be required to finance, develop, construct, operate and manage the projects on the 3,409-acre property in the towns of Ceiba and Naguabo on the eastern part of the island.

The Redevelopment Authority is overseeing the property, which was closed by the Navy in 2004, for 25 years as part of the Roosevelt Roads Master Plan for land use and development. It includes an airfield with an 11,000-foot runway, and areas controlled by the U.S. Army Reserve, Coast Guard and Department of Homeland Security.

The latter are listed as tenants, along with a marina, a school, law enforcement agencies and several offices, all of which have “an aggregate demand load of approximately 1,500 kVA [kilovolt-ampere] with average and peak loads of 1,200 and 2,000 kVA, respectively,” according to the RFP.

However, proposals must include the ability to manage future demand “and offer a strategy to achieve the necessary scalable results” for a predicted fully occupied property that will require a “load of up to 70,000 kVa with an average energy demand of 50,000 kVa.”

The Puerto Rico Electric Power Authority (Prepa) currently supplies electricity to the property via a transmission line that connects to a substation, from where power is distributed via the facility‐owned substations and distribution network. The property also has self‐contained utility systems such as water-sewer networks, treatment plants and communication stations. It also includes former Naval fuel storage and distribution infrastructure.

Interested microgrid developers may attempt to lease the existing infrastructure in a separate agreement from the RFP.

Proposals are due July 9.
