Wärtsilä announced that it has again been awarded a major contract by the Lower Colorado River Authority (LCRA). Following an order by LCRA for ten Wärtsilä engines generating an output of approximately 190 MW in 2022, the new order for a further ten Wärtsilä 50SG engines will double the earlier output. The order was booked by Wärtsilä in March 2024.

The new Timmerman Power Plant, located near Maxwell, Texas, will supply additional capacity needed to support LCRA's customers and support the Texas power grid and ERCOT. ERCOT supplies power to more than 26 million customers, or about 90% of the state's electric load. The additional capacity will help alleviate supply challenges created by load growth and the retirement of ageing plants in Texas.

Furthermore, the fast-starting Wärtsilä engines will provide dispatchable power to balance the increasing amount of intermittent renewables introduced into the system. There is a very high penetration of renewables installed and growing rapidly in ERCOT. LCRA?s new plant will operate on natural gas and will have two units, each powered by 10 Wärtsilä?

engines. The first unit is expected to come online in 2025, with the second unit scheduled to be completed in 2026. Together, the units will be able to provide power for about 100,000 homes during periods of peak demand.

The Wärtsilä 50SG engine consumes little to no water, which is an important feature in Texas, an area often affected by drought.
