Director of Puerto Rico power company resigns

SAN JUAN, Puerto Rico (AP) - The director of Puerto Rico's power company has resigned amid ongoing blackouts and scrutiny of a contract awarded to a small Montana-based company to help rebuild the electric grid destroyed by Hurricane Maria.

Puerto Rico's Electric Power Authority said Ricardo Ramos presented his letter of resignation to the company's board effective Friday. Officials said Ramos would soon provide additional information.

Ramos testified before a U.S. Senate committee this week about a $300 million contract awarded to Whitefish Energy Holdings that has since been canceled. The contract is undergoing a local and federal audit.

More than 20 of Puerto Rico's 78 municipalities remain without power nearly two months after Maria hit the U.S. territory as a Category 4 hurricane.
