The lights are slowly coming back on in Puerto Rico, thanks to a few outside companies.
Tesla is starting with a children's hospital.
The company installed a solar field and battery packs at Hospital del Niño in the capital, San Juan. As of Thursday, only about a quarter of the island's power was restored.
CEO Elon Musk said this is the "first of many solar + battery" projects on the island.
As Tesla gears up to expand its solar projects, a small Montana-based energy firm that was awarded a $300 million contract to help get Puerto Rico back on the grid is also causing a stir.
Puerto Rico Electric Power Authority awarded the contract to Whitefish Energy — a 2-year-old company that had only two full-time employees. The company is also from Interior Secretary Ryan Zinke's hometown.
Some lawmakers want Congress to review the circumstances of the contract and why it was given to such a small company.
The company later apologized.
