Markley, a Southington Republican, says the tax is illegal. The tax replaces a surcharge that was put in place a decade ago to pay back bonds that were used to reimburse Northeast Utilities for the value of generating plants that the company lost when electric restructuring forced the company out of the generation business. That surcharge expired at the end of 2010, when the money was paid back.
If the tax had not been added, the average CL&P ratepayer would have seen their electric bills decrease by 9 percent or 10 percent.
Markley is getting his day in court, as the case is being heard before the State Supreme Court in Hartford.
"The tax is unfair for two reasons," Markley has said. "It is levied by a state agency, which doesn't have the authority to do so and there are six towns that would be exempt from paying the tax."
The exempt towns are Wallingford, Norwich, Bozrah, Groton, Norwalk and Lebanon.
