The small Montana energy firm helping Puerto Rico rebuild its battered electrical grid is "standing down" over non-payment, the company said Monday.
In a statement, Whitefish Energy Holdings said that outstanding invoices with Puerto Rico's power agency have "made it impossible to continue."
Citing a letter sent Puerto Rican officials, the Associated Press reported that the government owes Whitefish more than $83 million.
The island canceled its $300 million contract with the company last month after the Washington Post reported, among other things, that it had only had two full-time employees when Hurricane Maria tore across Puerto Rico.
The power agency did not immediately respond to a request for comment, but a spokesman told the Associated Press that both sides are in talks to reach a satisfactory agreement for everyone.
