​Three Mile Island (TMI) Unit 1 is a single-reactor plant that generates 837 megawatts of zero-emissions energy: enough carbon-free electricity to power 800,000 homes. Unit 2 is owned by First Energy Company. TMI is so named because it is located three miles from Harrisburg International Airport.

We've been part of Londonderry Township and the Middletown area for more than 40 years. We provide hundreds of well-paying jobs and millions of dollars in economic support, including about $1 million in taxes annually for schools, roads and other public services. TMI's employees spend more than 100 volunteer hours and donate more than $300,000 to local charities and organizations annually.
