CenterPoint Energy in the United States has issued an all-source request for proposals (RFP) to supply 150,000 customers in southwestern Indiana with new generation, demand-side resources, and innovative solutions. The RFP specifies minimum capacity requirements for wind, solar, and batteries, while also considering coal, natural gas, hydrogen, and nuclear resources without publishing specific minimum capacities for these options. The utility aims to explore various technologies to enhance its long-term generation strategy and address changing market conditions. Proposals for the RFP are due by October 8, with a focus on fully accredited capacity by March 1, 2028. CenterPoint's integrated resource plan (IRP) aligns with the RFP, with plans to submit an updated version to the Indiana Utility Regulatory Commission in 2025. The utility is also looking to replace its 90-MW coal-fired F.B. Culley 2 generating unit, considering bids that can reuse the existing interconnection agreement with the Midcontinent Independent System Operator. CenterPoint prefers to be the owner of the new generating facility to ensure control over asset performance. The challenges faced in the MISO territory include unpredictable weather, resource outages, and increasing electric load, prompting the utility to emphasize attributes like ramp capability, energy duration, and fuel assurance in its long-term plan. CenterPoint's VP highlighted the importance of diversifying the energy portfolio to maintain reliable and cost-effective service for customers as the transition in electric generation continues.
