Multiday storage at scale for firm renewable electricity

Shared vision of XCEL ENERGY SERVICES, INC. and OCED:
1) Demonstrate the viability of iron-air battery technology for multi-day storage;
2) Demonstrate the competitiveness of a 100-hour continuous discharge system for long-duration energy storage applications;
3) Provide tangible benefits to impacted communities and workers aligned with local priorities and advance opportunities for historically underrepresented workers and businesses; and
4) Contribute toward widespread U.S. adoption of multi-day battery storage by 2030.

Statement of project objectives:
1. Minnesota storage: At the site of an existing power station in central Minnesota, build and operate a multi-day energy storage system using an iron-air battery with the capacity to discharge at least 10 MW continuously for 100 hours.
2. Colorado storage: At the site of an existing power station in southern Colorado, build and operate a multi-day energy storage system using an iron-air battery with the capacity to discharge at least 10 MW continuously for 100 hours.
3. Collect and share with DOE information and data regarding the following: (1) performance; (2) capital costs; (3) projections/business case; and (4) operating revenues and expenses.
4. At each site funded by the award, demonstrate successful development with community benefits activities to include: (I) engaging host communities, community-based organizations, and historically excluded stakeholders on topics such as workforce needs, project and technology specifics, (II) identifying and quantifying Justice40 benefits, and (III) developing pathways to facilitate hiring new employees from disadvantaged communities.
