The company will use its Advancion energy storage solution for installations at SDG&E’s sites in San Diego County, California.
The SDG&E-owned energy storage arrays will be operational by the end of January 2017. The arrays are expected to help in improving regional reliability and integrating greater amounts of renewable energy.
AES president and chief executive officer Andrés Gluski said: “AES recently made Advancion available to utilities, developers and commercial customers interested in owning our innovative and scalable solution, and SDG&E’s selection of Advancion highlights the significant growth potential we see for our energy storage business.”
The arrays will be installed at two SDG&E substation facilities -30 MW in Escondido and 7.5 MW in El Cajon.
They will the ability to offer 37.5 MW of power for four continuous hours and serve as a 75 MW of flexible resource to the grid.
SDG&E’s chief development officer James Avery said: “These batteries are beneficial because they maintain a reliable flow of energy to customers when they need it most.”
Since 2008, AES has been installing advanced battery-based energy storage onto electric grids, including recent installations in the United States, Northern Ireland and the Netherlands.
It has over three million megawatt-hours of delivered service across 136 MW of energy storage projects in four countries.
In February, AES officially started operation of the Advancion energy storage array in Vlissingen, Netherlands.
Featuring Advancion 4 advanced energy storage platform, the battery system adds the equivalent of 20MW of flexible resource to the grid.
