British Virgin Islands going 100% green

Thanks to battery-powered micro-grid technology, Anegada, one of the British Virgin Islands (BVI) relies on 100% PV green energy. The replacement of diesel-generation based power supply saves 1248t of CO₂ emissions per year.

Anegada is one of the main islands in the Virgin Islands archipelago, a British overseas territory east of Puerto Rico. The only island in the BVI to generate its own electricity, Anegada relied on diesel generators to supply power to its 450 residents and the 200 to 300 tourists who visit the island at peak times.

The BVI Electricity Corporation signed a contract with EPC companies Core Development and Power 52 to build a micro-grid project in Paraquita Bay. The system was commissioned in 2024 and includes solar PV, battery storage, power management and a substation. 

Battery powered microgrid

Saft delivered and installed the microgrid solution, consisting of:

  • A lithium-ion battery system 2MW / 5 MWh with 3 containers Intensium Max High Energy 800V 
  • A power conversion system LYNC of 2MW 
  • A microgrid controller and SCADA AutoLYNC 

The battery system stores energy from the adjacent PV array, making green energy available regardless of sunshine or cloud cover. Its grid-forming capability supports the stability of the local grid, ensuring a stable power supply in all conditions.

Local benefits

The microgrid now allows the island to be powered 100% by renewable energy, without the need to run diesel generators in parallel. The annual savings amount to:

  • 271,000 liters of diesel fuel
  • 1,248 tons of CO₂ emissions

In addition, the implementation and operation of the microgrid will be carried out in the British Virgin Islands by locally trained men and women. 
Finally, the Anegada microgrid will reduce the number of resources needed to operate the power plant on its sister island.
