At 1.1 million kilowatts, the company's Fermi 2 nuclear power plant represents 30% of Michigan's total nuclear generation capacity. This single plant is capable of producing enough electricity to serve a city of about one million people. Fermi 2 has been providing reliable, cost-effective power to DTE Electric customers for more than 20 years. The plant also has been designated as one of the nation's best-performing nuclear facilities.
