CHESHIRE, Conn. (AP) — Connecticut Light & Power has reimbursed a Cheshire woman almost $10,500 after acknowledging it billed her for 25 years for the electricity used to power streetlights near her home.

Grace Edwards tells the Hartford Courant she discovered the billing error after a prospective buyer for the house on Sir Walter Drive asked for a history of utility charges.

The utility says a developer who previously owned the home had agreed to pay for the lights.

The company initially refused to reimburse Edwards, but relented when the state’s Office of Consumer Counsel got involved.

The overcharges amounted to about $35 each month.

Mitch Gross, a CL&P spokesman, says the utility has apologized to Edwards for the error and inconvenience.
