Fall 2025 Updates to the Louisiana Generator Interconnection Queue

October 3, 2025 | Stacey Svendsen, Operations Director

Louisiana’s queue highlights the state’s dual role in both MISO South and SPP. The concentration of solar and hybrid resources in MISO shows merchant developer activity, while SPP filings add a smaller but still notable share. Gas projects, totaling 6 GW, remain a significant competitor, but renewables clearly dominate the state’s interconnection pipeline. Louisiana’s interconnection queue shows a diverse mix of solar, hybrid, wind, and gas resources, spread across both MISO South and SPP. The state has more than 18 GW of renewables under study, alongside 6 GW of gas, reflecting a balance of developer-driven and utility-driven proposals.
