Project Summary

Coneflower Energy, LLC (Coneflower Solar), an independent power producer and wholly owned subsidiary of Apex Clean Energy Holdings, LLC, seeks a permit to construct and operate an up to 235 megawatt (MW) alternating current photovoltaic solar energy generating facility and associated infrastructure in Lyon County, Minnesota. Coneflower Solar proposes to develop the project on approximately 1,723 acres within a site of 2,299 acres in Custer Township.

Coneflower Solar has designed this project to have flexibility in how it provides electricity to the grid with two potential connection scenarios: the MISO Scenario and the Garvin Scenario. In the MISO Scenario, Coneflower Solar will construct a new project substation in the north-central portion of the site and interconnect to the existing Lyon County to Lake Yankton 115 kilovolt (kV) transmission line via an Xcel Energy switching station and short (up to 500 feet) 115 kV transmission line.

In the Garvin Scenario, Coneflower Solar will construct a new project substation in the eastern portion of the site and interconnect via a short (up to 1 mile) 345 kV transmission line to the proposed Garvin substation from the Minnesota Energy Connection project. The Garvin Scenario will require a route permit from the Public Utilities Commission (PUC), and is dependent upon PUC approval of the Garvin Substation in the Minnesota Energy Connection project (Docket TL-22-132). Coneflower Solar will submit a Route Permit application, if needed for the Garvin Scenario, at a later date.
