This week, clean energy developer Invenergy said that it completed, in just four months, the construction of a 4-MWh battery storage system in Knoxville, Iowa for MidAmerican Energy. The system began commercial operation in December.
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.
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.
“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.
MidAmerican announced in 2016 that it plans to provide 100 percent renewable energy to its customers.
“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.”
