Upper Peninsula Power Co. signed two renewable power purchase agreements with Amber Infrastructure Ltd.-backed Circle Power.

The agreements cover the sale of 40 MW of wind power to Upper Peninsula Power, a subsidiary of Basalt Infrastructure Partners LLP, from eight turbines located in Houghton County, Mich. The turbines are slated to be operational by the end of 2023.

The contracts are among the lowest price utility-scale renewable power purchase agreements signed to-date in Michigan, the company said in a Sept. 21 news release.

Upper Peninsula Power in August issued a request for proposals for renewable energy resources, as part of its integrated resource plan. The utility is aiming to transition its energy portfolio to more than 50% renewable resources by 2025.

Amber Infrastructure is a subsidiary of Hunt Cos. Inc.
