More solar power is coming to Maine.

The Maine Department of Transportation announced that work began to install new solar arrays on Wednesday. They’ll be located in three state-owned spaces in Augusta.

The department says the arrays will be able to power state office buildings and save the state at least $7.2 million over the next 20 years.

“Once online, these arrays will help reduce costs for taxpayers and reduce emissions from state power consumption, in support of Governor Mills’ direction for state government to lead by example in renewable energy and sustainability,” said Department of Administrative and Financial Services Commissioner Kirsten Figueroa.

The sites are located inside the I-95 interchanges at Exits 109 and 112.

The panels will be owned and operated by Cenergy Power.
