Falling oil prices won\u2019t benefit Wilton\u2019s budgets until July 1, town officials tell The Bulletin, because contracts for different fuels are locked in for fiscal year 2015. According to the schools\u2019 director of financial planning, Ken Post, and the town\u2019s chief financial officer, Sandra Dennies, low gas prices have \u201cno impact\u201d on budgets, because the town locks in \u201cour diesel and heating oil prices while we are developing the following year\u2019s budget,\u201d Mr. Post said. Of course, as the budget process begins for fiscal year 2015, the town has a chance to lock in rates based on current prices. Each year, Wilton\u2019s schools use approximately 110,000 gallons of diesel fuel, and anywhere from 190,000 to 250,000 gallons of heating fuel, depending on the severity of the winter. On the other hand, the municipal government used 45,917 gallons of diesel, 46,252 gallons of gasoline, and 47,878 gallons of heating fuel last year. For 2015, the schools\u2019 diesel prices were locked at $3.10, and heating fuel prices were locked at $3.08 per gallon. The town\u2019s heating fuel prices ranged from $3.092 to $3.142 per gallon, depending on the size of the delivery. The introduction of natural gas as the main heating fuel at Wilton schools will \u201chopefully\u201d begin at the high school \u201csoon,\u201d Mr. Post said, a move that could save the town a significant amount of money. Cider Mill and Middlebrook should be converted by next summer. \u201cWhen oil prices were a little higher, we had estimates that we would save well over $200,000 per year,\u201d Mr. Post said.
