Wärtsilä to Equip Pair of Grid-Connected Texas Energy Storage Systems

The grid interconnected energy storage systems will have a total nameplate capacity of 200 MW

Helsinki-based technology group Wärtsilä will supply two Texas energy storage projects with its energy storage technology. The interconnected stand-alone systems will have a combined rated capacity of 200 MW.

Wärtsilä has also signed ten-year guaranteed asset performance agreements for the installations. The order was placed by Able Grid Energy Solutions, a utility-scale energy storage project development arm of MAP RE/ES, an energy investment firm.

The Madero and Ignacio energy storage plants will deliver valuable grid support to the Electric Reliability Council of Texas (ERCOT), the body responsible for managing the electric supply to more than 25 million customers.

Wärtsilä will supply its next-generation, fully integrated GridSolv Quantum energy storage solution. The modular solution is designed for ease of deployment and sustainable energy optimization. The energy storage systems will also feature Wärtsilä’s GEMS smart energy management platform to monitor and control the flow of energy, enabling these projects to provide grid support for critical periods during extreme weather or grid instability conditions, such as those that Texas has recently experienced.

“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.

The projects’ ten-year Wärtsilä Guaranteed asset performance agreements will enable flexibility in system maintenance and operation to maximize revenue in the ERCOT market. The agreements include maintenance services, an availability guarantee, and a flexible capacity guarantee based on usage.

The systems are expected to become fully operational starting in January 2022.
