Minnesota Power is seeking proposals for up to 725 MW of Battery Energy Storage System (BESS) resources

Minnesota Power (MP), a division of ALLETE, Inc., is issuing power supply Requests for Proposals (RFP) for up to 725 MW of Battery Energy Storage System (BESS) Resource. MP will consider bids for power purchase agreements and build own transfers. MP anticipates and will also consider self-build proposals in the RFP. This request is part of MP’s vision for a sustainable path to a carbon-free energy future and bold next steps in the clean energy transition that is centered on MP’s commitment to the climate, affordability, reliability, and communities.

MP has retained the services of an independent third-party evaluator to work with MP in the evaluation of all bids.

Proposals must be received by MP by the Proposal Submission Deadline of 12/18/2026. Self-build projects or bids from an affiliate must be submitted prior to the deadline per the schedule. MP reserves the right in its sole discretion to modify this schedule for any reason.

MP will consider proposals which include co-located BESS with wind as an option, however a wind project will be evaluated independently and must be submitted separately to MP’s Wind RFP. If submitting co-located proposals and detaching projects is feasible, MP has a preference for Bidders to also submit a wind only proposal in the open wind RFP.

Join Minnesota Power on Monday, November 16, from 10-11 a.m. CST for the opportunity to ask questions regarding the RFP.

Details to access the bidder meeting will be made available on this website prior to November 16.
