A report conducted by the Energy Storage Association and GTM Reseach states that the US is expected to deploy 220MW of battery storage in 2015 - 3 times what was deployed in 2014

In the US, the Indianapolis Power & Light Company (IPL) has announced a large-scale battery storage project, in which the utility will provide an advanced interconnected, battery-based storage system, with the aim of improving grid reliability and lowering costs for its customers.

The battery storage system will provide 20 MW of interconnected advanced, battery-based energy storage, equivalent to 40 MW of flexible resource to the electric grid, according to a company statement.

IPL adds the project will be the first grid-scale energy storage array in the 15 state Midcontinent Independent System Operator (MISO) grid system.

Battery storage for improved reliability

The AES subsidiary company claims that the battery storage facility will deliver enhanced grid reliability and ancillary services, including peak power supply.

The facility will also more efficiently balance supply and demand on the electric grid, translating into cost savings for its customers.

Kelly Huntington, IPL President and CEO said: “We are pleased to be able to bring the benefits of energy storage to our customers.

“Energy storage is a smart way to cost-effectively address a number of grid challenges including variability of energy supply and demand, while also improving the reliability of the grid.”

The construction of the battery storage facility, located in the southwest of Indianapolis, will begin this year and is scheduled to be in-service and operational in June 2016.

Says Michael Huber, president and CEO of Indy Chamber, an advocate organisation for local businesses and SMEs: “Indianapolis Power & Light Company continues to lead the charge in bringing innovative alternative energy solutions to our market and the development of this battery storage hub is just the latest example.

“Supporting the advancement of these energy alternatives is important for the competitiveness of our region and the sustained energy reliability our business community relies upon.”
