"They're doing an excellent job", he said. And the island's governor has his own plans.
The company is tasked with rebuilding some of Puerto Rico's power grid.
Techmanski also told The New York Times this month his company won the contract because he maintained better communication with the power authority than other companies. Rather than joining hands, they're increasingly pointing fingers, accusing each other of inaction or incompetence.
PREPA declared bankruptcy in July.
Mr. Trump asked Mr. Zinke in the Oval Office meeting that he had nothing to do with the contract awarded to Whitefish Energy Holdings, a firm that had two employees before the deal.
A federal control board that oversees Puerto Rico's finances announced this week that retired Air Force Col. Noel Zamot will be in charge of power reconstruction efforts.
A financial oversight board Congress created for Puerto Rico is planning to go to a federal court this week to seek clear authority to examine contracts as small as $10 million.
At the same time, the island's governor, Ricardo Rosselló, who now controls PREPA, may file suit to block Zamot from taking over, arguing that the control board is making a power grab and exceeding its authority.
Rossello said that at least $8 million has been paid to Whitefish so far, but "there can not be any kind of distraction that alters the commitment to restore electrical power as soon as possible in Puerto Rico".
If Zamot focuses on restoring power, he could be the kind of storm boss the power industry wants. "This was something exclusively determined by the Puerto Rican government".

The Federal Emergency Management Agency (Fema) has denied claims by The Puerto Rican Electric Power Authority (Prepa), the USA territory's main utility, that it reviewed the deal.
But even on Friday, the accusations continued.
The contract with Puerto Rico's power utility has come under increased criticism after it was revealed that the terms were obtained without a competitive public bidding process. He again praised Whitefish's work. The company later apologized. It had never worked on a project close to the scale of the Puerto Rico power restoration. It has since hired more than 300 workers.
A house is lit up with the help of a generator in Old San Juan on October 26. Zinke has said he had nothing to do with the contract. Whitefish has said the company has expertise in mountainous areas, and arrived in Puerto Rico before other companies.
The company is headquartered in the town of Whitefish, the hometown of US Interior Secretary Ryan Zinke.
Zinke's office told the Post that he had had no role in the contract.
FEMA said it has not approved any reimbursement requests from the power company for money to cover repairs to the island's electrical system.
Ramos also said the Federal Emergency Management Agency had approved of the deal, something the agency has denied.
"If there is no wrongdoing, if it has been done correctly, then we will push forward", Rosselló said.
