TRC Companies has been awarded a $490,000 contract by Public Service of New Hampshire, or PSNH, a Northeast Utilities company, to place a spare auto transformer into service in Littleton, NH. The project is one element of PSNH's 10-year plan to update the electrical grid in New Hampshire to ensure the more reliable delivery of power to customers. Under the contract, TRC will create a new 115kV bay position so the existing spare autotransformer at the Littleton substation can be placed into service. The new transformer will link to the regional transmission grid via a new 2,500-foot tap from National Grid's 230kV transmission system.
