U.I. had requesting an increase that would have seen the average customer's bill rise about $200 per year.

Instead, state regulators approved a rate that will see bills go up by about a third of that.

U.I says the decision could lead to a loss of nearly $32 million for the company.

No word on when the court might consider the appeal.
