A large-scale battery storage system will be built in Texas for the U.S.’s biggest electric utility cooperative, to time-shift solar-generated loads and provide grid services to transmission operator ERCOT.
Mobile energy solutions provider Aggreko, which recently took over German-U.S. energy storage pioneers Younicos and incorporated it as a division of the parent company, announced to Energy-Storage.news yesterday that it has signed an agreement for a 2.25MW / 4.5MWh battery storage project with Pedernales Electric Cooperative (PEC).
According to Karim Wazni, managing director of Aggreko Microgrid and Storage Solutions (essentially formerly Younicos), the cooperative picked his company out for the project due to its existing track record of “active and successful participation in the ERCOT market.” Aggreko has already executed five battery projects in Texas, including the ongoing updates and upgrades of the large-scale battery system at Notrees Wind Farm.
The project is notable for two reasons: firstly, that in addition to providing power services to ERCOT markets, the battery storage system, which should be capable of storing and discharging 2.25MW of power for two hours, will also provide energy capacity to the local network. As a general trend, customers for large-scale energy storage systems are now seeking this longer duration energy storage as well as the ability to use batteries for high powered, short duration applications, Saft’s Michael Lippert pointed out in a recent interview.
The second notable aspect for Aggreko Microgrid and Storage Solutions is that unlike other recent projects, and the projects it is currently working on going forwards, this project for PEC is an asset sale, as opposed to the mobile power ‘as-a-service’ or energy storage ‘as-a-service’ business model the company is rapidly becoming known for. “In this case, the storage project is an asset sale, which is what the cooperative was looking for, not an as-a-service offer,” an Aggreko spokesperson told Energy-Storage.news yesterday.
Going forwards, Aggreko is expected to unveil a large project in New York State soon which will provide National Grid with solutions to defer spending large sums expanding transmission and distribution (T&D) infrastructure in the next few days. “We will be inaugurating a plant in New York State in two weeks, it’s a National Grid project where we’re providing 2MW of power for two hours, and that will be able to deliver peak shaving services to a substation,” Wazni said, adding that even these sorts of larger infrastructure projects could be done ‘as-a-service’.
