State says Constellation owes $2.5m in taxes, interest

The state comptroller's office says Baltimore-based Constellation Energy owes more than $2.5 million in back taxes, interest and penalties.

The comptroller's office filed a lien in December for money it says the energy company owes for the 2006 and 2008 tax years. Most of the amount is interest — the taxes claimed come to just under $440,000.

"It hasn't been paid, and this is part of our normal process, to file a lien," said Christine Feldmann, a spokeswoman for the comptroller's office.

Constellation, bought by Exelon Corp. in 2012, said in a statement that it only recently learned of the lien.

"We've contacted the Comptroller's office to determine why the judgment has been filed, and we're currently working with them to resolve the issue," Constellation spokeswoman Kelly Biemer said in the statement.
