The latest announcement follows a four-month construction process that culminated with the battery becoming operational in December 2018.
The lithium iron phosphate battery project is expected to enable MidAmerican Energy to store electricity for later use.
The battery is capable of providing 4MWh of storage capacity, supplying 1MW of power for up to four hours, which is adequate electricity to power about 900 average households in Iowa.
Invenergy senior vice president, responsible for storage development at Kris Zadlo said: “We are excited by the new opportunities for battery storage that we are seeing around the country.
“We are grateful for partners like MidAmerican Energy who are seeking innovative ways to deliver value to their customers and are proud to have provided them with this solution in such a short time.”
The battery storage system becomes the fifth utility-scale advanced energy storage project Invenergy has developed and the first project where the company acted as the engineering, procurement, and construction (EPC) provider.
Recently, Invenergy has started commercial operations at 1,485MW natural-gas fired combined-cycle power plant, Lackawanna Energy Center.
The Lackawanna Energy Center is built just outside of Scranton, in Pennsylvania, US. The facility generates enough electricity to meet the power consumption needs of more than a million American households.
The Lackawanna power plant is completed ahead of schedule and is equipped with three GE 7HA.02 air-cooled natural gas combustion turbines.
Invenergy says that the HClass turbine units enable operational flexibility that helps the Lackawanna Energy Center to produce baseload power.
The units are also designed to help the power plant to quickly respond to variations in energy demand, thereby supporting the continued growth of renewable resources in the region.
Invenergy along with its affiliated companies develop, own, and operate large-scale renewable and other clean energy generation and storage facilities in the Americas and Europe.
