Carlton, MN (NNCNOW.com)--- Following nearly two years of repairs to damages sustained in the 20-12 flood, Minnesota Power has announced plans to bring the state's largest hydro-electric facility back on line.

$90 million dollars was invested for reconstruction for the Thomson Hydro Station in Carlton

The station is expected to be back up and running this summer as soon as approval comes from federal regulators.

In June of 20-12 floodwaters on the St Louis River swamped the six Thomson turbines, overtopped the Thomson reservoir, and breached a portion of an earthen dike at the forebay, a shallow reservoir that feeds water into the generating station.

The 22-month project includes the replacement of electrical infrastructure, cleanup of the turbines that were underwater for weeks, rebuilding of the forebay, and refurbishing generators that were damaged in the flood.

"It's a significant investment but it's certainly one that's worthwhile. This is a no-cost renewable energy resource for our customers and certainly it's been an important part of our history and it will continue to be an important part of our future energy mix," said Amy Rutledge, Manager of Corporate Communications for MN Power.

Minnesota power will be holding a series of celebrations this summer in towns that are hosts to hydro facilities.
