How to switch to or cancel Constellation
Switching electricity providers in a deregulated market is simple: compare current plans for your address, pick one, and the new provider handles the switch — there’s usually no interruption in service. If you’re on a fixed-term plan, check the Electricity Facts Label for any early termination fee before leaving. Start by comparing Constellation against other providers by ZIP.
