Invenergy, a privately held global developer and operator of sustainable energy solutions, announced the start of commercial operations of a utility-scale battery storage system located in Knoxville, Iowa that Invenergy developed for MidAmerican Energy.
The lithium-iron phosphate battery project will enable MidAmerican Energy to store electricity for later use. The storage project aims to enhance the reliability of renewables by storing energy produced when wind speeds and sun exposure are high for later use.
“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 provider. Invenergy is a owner-operator of battery storage systems, experience that shaped its approach to this project.
The announcement follows an impressive four-month construction process that culminated with the battery becoming operational in December 2018.
