About the Request for Proposal (RFP)

IPL's 2019 Integrated Resource Plan (IRP) identified a Preferred Resource Portfolio that includes approximately 200 megawatts (MW) of replacement capacity. The purpose of this all-source request for proposal (RFP) is to competitively procure replacement capacity by June 1, 2023, which is the first year IPL is expected to have a capacity shortfall. IRP modeling indicates that a combination of wind, solar, storage, and energy efficiency would be the lowest cost options for the replacement capacity, but IPL will assess the type, size, and location of resources after bids are received.

IPL is issuing this RFP for firm capacity resources within the IPL service territory. IPL forecasts that 200 MW of additional unforced capacity (UCAP) will be needed by June 1, 2023. Proposals will be accepted for all or a portion of the capacity needs. IPL will estimate the UCAP for wind and solar resources from the methodology described in the MISO Renewable Integration Impact Assessment Version 6, dated December 2018. Proposed resources must be located within the IPL service territory or have the transmission system interconnection directly interconnected to the MISO Zone 6 network. Proposed resources may include (a) capacity from new facilities, (b) new incremental capacity at existing facilities, (c) power purchase agreements (PPAs) or, (d) demand-side management opportunities. The capacity resources may be proposed for any of the following:

• Asset transfer proposal
• Power purchase agreement proposal
• Demand response proposal
