The first phase had a 1,200 psi boiler and 3.15-MW turbine along with two 32-MW, 350 psi turbogenreators. This was the first commercial 1,200 psi turbine in the world, more than double the pressure that had ever been used before. By 1930,it was the largest tidewater electric plant in the East. The station was closed in 1970 and in 1976 was named a National Historic Mechanical Engineering Landmark.

Mount Tom
Location: MA
Operator: GDF SUEZ Energy North America
Configuration: 1 X 136 MW
Operation: 1960 (ret)
Fuel: bituminous coal, oil
Boiler supplier: RS
T/G supplier: GE
EPC: UE&C
Quick facts: Mt Tom is on an 80ac woodland tract on the Connecticut River near Holyoke. Unusually for its northern location, the plant has an outdoor boiler structure. It went into service as a coal-fired unit, was converted to burn oil in 1970, and was reconverted to coal in 1981. Normal fuel burn was about 1,200 tpd of coal with onsite storage space for about 150,000t. In Aug 2005, Babcock Power Inc broke ground on a new SCR for Mt Tom. The unit already had Riley CCV low NOx burners plus overfire air and was the location of a demonstration installation of the Praxair Oxygen Enhanced Combustion (OEC) low NOx technology. In Dec 2009, a new BPI Turbosorp FGD scrubber went online along with a new baghouse. The unit was closed in Dec 2014. This caused the loss of about $600,000/yr in local property taxes.
