CHICAGO (Jan. 14, 2019) – Invenergy, a leading privately-held global developer and operator of sustainable energy solutions, today announced completion of construction and the start of commercial operations of a utility-scale battery storage system located in Knoxville, Iowa that Invenergy developed for MidAmerican Energy. Today’s announcement follows an impressive four-month construction process that culminated with the battery becoming operational in December 2018.

The lithium iron phosphate battery project will enable MidAmerican Energy to store electricity for later use. The battery can provide four megawatt-hours of storage capacity, supplying one megawatt of power for up to four hours—enough electricity to power about 900 average Iowa homes.

“We are excited by the new opportunities for battery storage that we are seeing around the country,” said Kris Zadlo, Senior Vice President, responsible for storage development at Invenergy. “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.” 

This is the fifth utility-scale advanced energy storage project Invenergy has developed, and the first where the company acted as the engineering, procurement, and construction (EPC) provider. Invenergy is a leading owner-operator of battery storage systems, experience that shaped its approach to this project.
