Wärtsilä to supply and maintain two major interconnected energy storage systems for Texas grid services


Two standalone battery energy storage systems (BESS) totalling 200MW of output will be deployed in Texas’ ERCOT market by the energy division at Wärtsilä Corporation. Finland-headquartered marine and power systems technology manufacturer, which has become one of the biggest system integrators for energy storage in the US market, said today that it has been awarded contracts for the two projects in Southern Texas by developer Able Grid Energy Solutions.To learn more, read, “Texas’ grid to get 200MW of battery storage from Wärtsilä”,“Wärtsilä to supply two major interconnected energy storage systems for Texas grid services”,and“Wärtsilä wins order for utility-scale energy storage to support Texas electric grid.”

Key Takeaways:

  • Wärtsilä Energy will supply its recently-launched GridSolv Quantum advanced energy storage solution to both sites, as well as the company’s GEMS energy management software and controls platform.
  • The systems, called Ignacio and Madero, are thought to be around 100MW each, equalling the US state’s largest battery storage project under construction so far, the 100MW Chisholm Grid BESS which is also an Able Grid project.
  • “Able Grid selected Wärtsilä technology, among other considerations, for its critical safety and cyber-security features. The system complies with all applicable standards, like UL9540A, to ensure sustained safe and reliable operations. In addition, the GEMS Power Plant Controller is U.S.-code based and meets all IEC62443 cybersecurity standards,” commented Sharon Greenberg, Able Grid Chief Operating Officer.

Path to 100% Perspective:

Storage technologies will be essential to maintaining stability in the power grid as the world shifts from power systems based on fossil fuels to renewables and carbon-free and carbon-neutral fuels. Batteries will provide ideal solutions to keep the lights on during normal / average weather, while unusual and extreme weather events such as those recently experienced in California and Texas will require integrated long-term storage solutions that ensure security of supply in the face of seasonal and weather-related variability. Flexible generation power plants are also part of the solution as they can operate on carbon-free and carbon-neutral fuels and can provide the essential firm power component to our power systems of the future.
