LUDINGTON, Mich., Nov. 22, 2012 /PRNewswire/ --Consumers Energy's $250
million Lake Winds Energy Park began serving electric customers today with a
formal declaration that it has begun commercial operation.

Lake Winds is Consumers Energy's first wind park and has a generating capacity
of 100 megawatts. It consists of 56 wind-generation turbines, all located in
Riverton and Summit townships in Mason County. The utility's investment in
Lake Winds was made possible by Michigan's landmark energy reform law.

"Consumers Energy thanks Mason County and area governmental officials in
particular, for making today's 'start-up' possible. Construction of Lake Winds
honored our company's commitments to safety and good communication with area
residents," said Bill Schoenlein, manager of hydro and renewable generation
for Consumers Energy. White Construction Inc. was the lead contractor for the
Lake Winds facility. More information on Lake Winds is available at
www.lakewindsenergypark.com

Consumers Energy is the largest supplier of renewable energy in Michigan. The
utility is on track to meet a requirement in Michigan's energy law that by
2015, 10 percent of the electricity it provides to its 1.8 million electric
customers will come from renewable sources in the state.

"Completion of this project puts Consumers Energy on its way to meeting the
2015 requirement. The addition of Lake Winds to the company's portfolio of
renewable sources increases its renewable supply to 7 percent of retail sales.
The completion of other projects under development will increase our renewable
supply to 8 percent by the end of 2012," said David Ronk, Consumers Energy's
director for transactions and resource planning.

Consumers Energy, the principal subsidiary of CMS Energy (NYSE: CMS), provides
natural gas and electricity to 6.8 million of Michigan's 10 million residents
in all 68 Lower Peninsula counties.
