Energy Minister Angus Taylor has announced 443 facilities had been given the green light for up to $25,000 in grants.

"This will help lower their energy bills by upgrading to more energy efficient air-conditioning, refrigeration and equipment, improving the building through double glazing and insulation, carrying out energy audits or installing energy monitoring equipment," he said on Friday.

It's also expected to create a business boom for local electricians, carpenters, engineers, and plumbers.

"These grants will help fund projects that will provide genuine and lasting energy savings that will reduce operating costs and have a positive flow-on effect for jobs and small businesses into the future," he said.

More than 85 per cent of the grants have been allocated to hotels in regional or remote Australia.

Hotels, motels and serviced apartments with up to 99 rooms were eligible to receive grants under the program.

Stephen Ferguson, national CEO of the Australian Hotels Association, said the grants would help struggling businesses trying to recover from the worst 15 months the industry has ever experienced.

"Energy costs are one of the largest on-going expense for many hotels and the bills keep coming, even when a hotel has its doors shut during a lockdown," he said.

"So anything that can be done to bring down power costs is welcome."

Energy Efficiency Council chief Luke Menzel said it would also take pressure off the electricity grid and deliver lower emissions.
