Application Summary

Overview: WP&L filed an application with the Commission for a CA to construct three solar energy generation facilities, and an application for approval of affiliated interest agreements for three solar energy generation facilities that are seeking CPCN from the Commission. In total, WP&L is seeking authority to acquire, construct, own, and operate 675 MW of new solar energy generation facilities. The three sub-100 MW solar facilities that require a CA from the Commission are NRS and RCS, both proposed at 50 MW, and CRS, proposed at 75 MW. The three solar projects that are subject to CPCN requirements and their respective CPCN docket numbers are Wood County Solar (9803-CE-100), Grant County Solar (9804-CE-100), and Onion River Solar (9805-CE-100).

Applicant stated need: WP&L states in the application that it conducted an analysis that shows there would be benefits to its customers if it increased its renewable energy generation and retired certain of its coal generation facilities. The application states that these projects are part of a larger program that would save customers money over the next 35 years compared to maintaining its current generation fleet.

Estimated cost: WP&L states that the estimated cost to acquire, construct, install, and place in operation the six proposed solar projects in this docket is approximately $887 million, calculated without Allowance for Funds Used During Construction (AFUDC). This project cost includes an estimated $862 million in construction costs and an estimated $25 million in land purchase costs. Because WP&L intends to finance approximately 35 to 45 percent of the project's estimated construction costs with capital from a tax equity partner, WP&L requests authorization to include in rate base up to $585 million, plus AFUDC, subject to Commission review and audit in a future rate case proceeding.

Project Location: Crawfish River Solar project, located in the Town of Jefferson, just west of the City of Jefferson in Jefferson County. North Rock County Solar project, located in the Town of Fulton, southwest of the City of Edgerton, in Rock County. Richland County Solar project, located in the Town of Buena Vista, near the Village of Lone Rock, in Richland County.

Proposed schedule: WP&L states for each of the solar CA projects that a site-specific construction specification and schedule would be developed but is not yet available. Dependent on regulatory schedules and approvals, the project schedule for CRS and RCS would tentatively have construction starting in summer of 2021. The construction schedule for NRS tentatively has construction starting in summer of 2022. Each of the CA projects is expected to take between 12 to 18 months to construct. The estimated project schedule would have the CRS and RCS projects placed in service in November of 2022, with NRS placed in service in November of 2023.

Statutory Review
