As an Exelon company, Constellation Energy is part of one of the biggest — and historically most polluting — corporations in North America. Given Exelon’s vast production energy, ranking on the PERI Toxic 100 list is perhaps not that surprising. The good news is that Exelon is upfront about its room for eco-friendly improvement and make it easy for Constellation customers to go green, too.

As a renter, you’re likely concerned about getting your electricity contract’s start and end dates to match your lease term as close as possible. In most cases, your electricity provider will offer flexible start dates and some even offer same-day connections. If you can’t line up your electricity contract exactly with your lease term, it’s okay. It’s better to choose an electricity plan with a slightly longer contract term than your apartment lease if necessary. If you move and provide proof of a change in address, your electricity provider cannot charge you an early termination fee.
