MAN Energy Solutions’ modular power-plant concept with 18V51/60G gas engines has a total capacity of 124 MW to support Texas plant.
MAN Energy Solutions is supplying six 18V51/60G gas engines with a total capacity of 124 MW to a peak-load power plant in Texas for the Kerrville Public Utility Board (KPUB) to boost grid stability and offer fast, flexible power.
“Our engines reliably and efficiently deliver electricity whenever required and as long as necessary,” said Johann Stocks, Head of Power, Americas at MAN Energy Solutions. “Similarly, their exhaust after-treatment system has been specifically developed and optimized for the requirements of the U.S. market to achieve ideal emission values."
KPUB will operate the engines using natural gas. The exhaust after-treatment system minimizes harmful emissions through catalytic reduction and oxidation catalysts. The engines' ability to operate with synthetic methane, biofuels, or a hydrogen mixture offers additional pathways to reduce CO2 emissions further.
“We’re proud of the experienced team we’ve assembled for this project, with MAN Energy Solutions serving as its foundation,” said Mike Wittler, KPUB General Manager and CEO. “Their technology, professionalism, and support through the early stages of development have impressed us at every turn. This partnership strengthens our ability to protect our ratepayers and continue offering some of the lowest electric rates in Texas for decades.”
MAN Energy Solutions will transport the engine to the Texas power plant along with engine—and plant-specific systems and components. The engines are scheduled for delivery in mid-2026 and will start operating in 2027.
"We are delighted that KPUB has chosen our proven gas engines that are already being used in a large number of power-plant projects worldwide,” said Alexander Stöckler, Head of Sales, Tendering & Project Management, Power Segment at MAN Energy Solutions. “As a reliable and efficient solution, they will prove ideal for ensuring grid stability. This is now our second power-plant order for 18V51/60G engines in the United States, boosting our reputation as a competent partner for American gas power-plant projects."
The Texas Energy Fund (TEF) finances gas-fired power generation projects in Texas and has selected the project for potential support, currently undergoing the fund’s due diligence process. MAN Energy Solutions has supported KPUB throughout the application process and continues to assist during the review phase.
MAN Energy Solutions is delivering its modular power-plant concept through this project, which features prefabricated assemblies that reduce complexity and accelerate the construction process. Clear building interfaces significantly facilitate planning with other project participants.
KPUB’s future power generation facility will be constructed adjacent to the Sky Global Power One in Colorado County, Texas, leveraging existing infrastructure and a proven operational location.

Last week, MAN Energy Solutions completed the Type Approval Test (TAT) for its dual-fuel MAN L35/44DF engine. Both variants of the 35/44DF engine were tested: the methane-capable 35/44DF CD and the methanol-compatible 35/44DF CD. They are designed as auxiliary generator sets (720 RPMs) and for electric propulsion (750 RPMs).
“The 35/44DF CD is a future-proof concept with all the latest technology, including full connectivity and cyber security,” said Sephardim Koblenz, Vice President and Head of Licensing, Four-Stroke Marine & License, MAN Energy Solutions. “The 35/44DF CD’s reliability, fuel efficiency, low methane-slip, and cost optimization are also crucial to the engine’s resumé. In developing this engine with our partner, STX Engine, we had low cost and easy localization as clear targets.”
Six classification societies participated in testing at STX Engine’s Changwon headquarters in South Korea from April 7 to 11.
