Ludington Pumped Storage: Michigan鈥檚 鈥淏ig Battery鈥�

Mr. John Broschak

Vice President, Consumers Energy Company

Abstract

Between 1969 and 1973, Michigan鈥檚 two largest utilities鈥擟onsumers Energy and DTE Energy鈥攋oined forces to build the world鈥檚 largest pumped storage plant along the shores of Lake Michigan. At the time, the $327 million project was the largest of its kind, earning it a spot on the list of Michigan鈥檚 Top 10 Civil Engineering Projects for the 20th Century. 

Today, the plant remains a major contributor to Michigan鈥檚 electric grid鈥攅nsuring affordable, reliable energy for the state鈥檚 residents. The plant鈥檚 technology is unique in that it responds quickly to energy demands. When demand is low, typically at night, Ludington鈥檚 reversible turbines pump water from Lake Michigan 363 feet uphill to the reservoir. And during the day, when demand for electricity is high and the cost of energy is greater, the pumps are reversed, and water flows back down through the pipes, turning turbines that produce affordable electricity. 

The 27-billion-gallon man-made reservoir measures 2.5 miles long and one mile wide. It can generate over 2,000 megawatts of electricity and produce over 15,000 megawatt hours. The plant is currently undergoing a seven-year, $800 million upgrade, with plans for completion in 2020.

This presentation will discuss the engineering marvel that is Ludington Pumped Storage, including an overview of the plant鈥檚 numerous grid benefits and upgrade schedule. It will also discuss the importance of pumped storage as an energy source, comparing it to the increasingly popular topic of battery storage.
