About the Request for Proposal (RFP)
The purpose of this 2022 all-source RFP is to competitively procure energy and capacity in the near term and to inform AES Indiana’s 2022 Integrated Resource Plan (IRP) development. Competitive proposals for energy and capacity available beginning for the 2025–2026, 2026–2027, and/or 2027–2028 MISO Planning Years will be accepted for evaluation. AES Indiana will accept proposals of any range of energy and capacity. AES Indiana is interested in both Asset Transfer Agreements (ATAs) and Power Purchase Agreements (PPAs) for all viable replacement technologies to fill this potential capacity need. PPA durations may be as short as three (3) years and as long as 30 years. AES Indiana will also consider ATA proposals that can utilize the remaining interconnection rights associated with Petersburg Generating Station Unit 2 retirement, not to exceed 200 MW.
This RFP is intended for energy and capacity and generation resources, preferably within or connected to, the AES Indiana service territory. Proposals will be accepted for all ranges of energy and capacity needs, including traditional and commercially ready untraditional technologies, including, but not limited to, thermal, wind, solar, battery energy storage, hydrogen, geothermal, biomass, or such combination of energy and capacity resources. AES Indiana will estimate the Unforced Capacity (UCAP) for solar resources from a fundamental view of solar penetration and contribution to peak load in alignment with (or similar to) the MISO Renewable Integration Impact Assessment dated February 2021. Wind UCAP will be estimated from the most recent MISO Effective Load Carrying Capability (“ELCC”) study. Proposed resources are required to deliver capacity to the MISO Local Resource Zone (LRZ) 6.
