PowerSouth Energy Cooperative announced a major expansion of its Lowman Energy Center (LEC) in Leroy, Alabama, by adding a second advanced‑class M501JAC gas turbine from Mitsubishi Power. The decision comes amid a rapid increase in regional energy demand driven by reshoring of manufacturing, broader electrification, and the growing computational load of artificial‑intelligence applications. By leveraging its existing control‑room infrastructure, a workforce already trained on the M501JAC platform, and a long‑term partnership with Mitsubishi Power and Burns & McDonnell, PowerSouth expects the upgraded facility to deliver more than 1 GW of reliable, winter‑peak power to its distribution members in Alabama and Northwest Florida. The expansion not only boosts capacity but also aligns with emissions‑compliance goals and the cooperative’s “Smart Grid” strategy, positioning the LEC as a cornerstone of the region’s evolving energy landscape.
PowerSouth Expands Lowman Energy Center with a New Mitsubishi Turbine
PowerSouth selected Mitsubishi Power Americas, Inc. to supply a second heavy‑duty M501JAC turbine, designated “LEC 3.” This unit joins the first M501JAC turbine that entered service in 2023, making Lowman the only plant in the Southeast with two of Mitsubishi’s advanced‑class machines. The turbine will operate under a 25‑year long‑term service agreement that includes performance guarantees, scheduled upgrades, and emissions‑compliance support. Burns & McDonnell will provide full engineering, procurement, and construction (EPC) services, ensuring that the project proceeds on schedule and within budget. The addition of LEC 3 pushes the plant’s total output to over 1 GW, a milestone that reflects both the cooperative’s strategic planning and the strength of its industry partnerships.
Leveraging Existing Infrastructure and Workforce
The cooperative will integrate LEC 3 into its existing control room, a move that minimizes capital outlay and accelerates commissioning. Because PowerSouth’s staff have already been trained on the M501JAC platform, the transition to the new unit is expected to be seamless, reducing the learning curve and operational risk. The simple‑cycle design of the M501JAC delivers the highest output per footprint in simple‑cycle operation, allowing the plant to ramp up or down more quickly than a combined‑cycle facility. This flexibility is critical for PowerSouth’s traditionally winter‑peaking system, where rapid response to demand spikes can prevent outages. The added turbine lifts winter capacity from 696 MW to more than 1 GW—enough electricity to power roughly 694,000 homes across the service area.
Strategic Fit Amid Rising Energy Demand
PowerSouth cited several fast‑moving energy drivers as the catalyst for the expansion: reshoring of manufacturing facilities to the Southeast, accelerated electrification of residential and commercial sectors, and the surge in AI‑related computing workloads that demand reliable power. Bill Newsom, President and CEO of Mitsubishi Power Americas, emphasized that the project “shows real foresight in meeting the surge in demand we’re seeing across the region.” By adding a second M501JAC turbine, PowerSouth aims to address this surge while maintaining emissions compliance and operational efficiency. The cooperative expects the high efficiency of the turbine to translate into affordable power for its members, delivering cost savings that flow directly to households, schools, businesses, and industrial customers.
Outlook
With the Lowman Energy Center now poised to exceed the 1 GW threshold, PowerSouth anticipates a strengthened role as a dependable winter‑peak provider and a platform for future growth. The additional capacity creates headroom for anticipated load increases tied to continued reshoring, data‑center construction, and broader electrification initiatives. Moreover, the expansion dovetails with PowerSouth’s ongoing “Smart Grid” initiatives, including demand‑response programs and the integration of distributed energy resources. Mitsubishi’s 25‑year service contract, with its performance guarantees and scheduled upgrades, helps keep operating costs predictable and emissions below regional caps. As the Southeast continues to attract new manufacturing and technology investments, the upgraded LEC positions PowerSouth to meet that load without resorting to costly fossil‑fuel imports or large‑scale construction delays, reinforcing the cooperative’s mission to provide reliable, affordable power to the communities it serves.
Key Takeaways
- PowerSouth is adding a second Mitsubishi M501JAC turbine (LEC 3) to the Lowman Energy Center, bringing total capacity to over 1 GW.
- The turbine will operate under a 25‑year service agreement with Mitsubishi Power, while Burns & McDonnell provides EPC services.
- Winter‑peak capacity will increase from 696 MW to more than 1 GW, enough to serve approximately 694,000 homes in Alabama and Northwest Florida.
EnergyInsyte's Take
The expansion demonstrates PowerSouth’s proactive stance on capacity shortfalls and its reliance on proven, high‑efficiency technology to meet growing load. Executives should monitor the plant’s simple‑cycle performance and the long‑term service agreement terms, as these will influence cost recovery and reliability metrics in a market where demand is accelerating faster than new generation comes online.
