USVI Energy Roadmap

EDIN is an international partnership between USA, New Zealand, and Iceland started in 2008.

Why Islands? Islands are often highly dependent on fossil fuels for

electricity and transportation and often have very high retail electricity rates

Islands often have abundant renewable resources and small populations, so are ideal places to showcase the future of high renewable energy penetration.

Feb 2010 – Declaration of our mission

At the MOU signing ceremony with DOE and DOI, Gov. deJongh, Jr. announced his goal to reduce USVI’s dependence of fossil fuel by 60% by 2025.

“There is no reason why the Virgin Islands cannot be the leaders in clean energy deployment in the Caribbean,” deJongh said.

Key Findings

• It can be done, but only with all stakeholders pulling together, in the same direction.

• The kitchen sink – it’s going to take everything to get to 60% by 2025.

• WAPA must lead. All scenarios include waste-to-energy and increased generation/water efficiency.
