The Capitol Area System (CAS) is one of the oldest and most polluting energy facilities in the state. It’s located on Capitol Avenue in Hartford. It was a cogeneration power plant that began operating in Hartford in the late 80's. It’s no longer providing power for the grid, but still operates to heat and cool 18 state and private buildings. In 2022, it was purchased by the state, and is in need of repair. Connecticut's Department of Administrative Services (DAS) has been looking for solutions for updates of CAS. In March of 2024, DAS published the CAS Decarbonization Study. Sierra Club Connecticut is advocating for a 100% clean and renewable solution. Check out our factsheet here. 

 

Since the state purchase in 2022, Sierra Club Connecticut has been organizing to make this dirty energy facility transition to 100% clean and renewable. 

 

On Thursday, November 21, we hosted an educational community meeting in Hartford. Over pizza, we updated community members on the background of the Capitol Area System, and the options for how to proceed. Folks took action by sending a message to Governor Lamont and writing letters to the Commissioner of the Department of Administrative Services, Michelle Gilman.

 

Here's how you can help. Send your own message to the Governor asking to make the Capitol Area System 100% renewable.
