Berlin-based utility Yankee Gas, which is owned by Northeast Utilities, said it surpassed its goal last year for converting customers to natural gas.
Yankee said it converted more than 5,500 customers and added 20 miles of new gas main last year. It had set a target of 5,200 conversions.
Yankee said state regulators have assisted by approving recommendations that give the utility more flexibility in developing projects and make it easier to enroll new customers.
Wilton was the site of Yankee’s first major expansion, starting in July.
The company said it has several other large-scale projects in the works for this year.
