The future addition of a fifth boiler and a steam turbine/generator set at Harvard's Blackstone Steam Plant
called for an upgrade in the capacity of the electrical
switchgear. J. F. White was contracted to furnish and install a
new Low Voltage Substation into which the new switchgear was
installed. Also installed were two new transformers on top of
the new substation along with a new MCC on the Turbine Hall
deck. To allow for the construction of the new Low Voltage
Substation, it was necessary to make modifications to the 400#
steam system and furnish and install new structural steel.
J.
F. White also replaced an existing gas fired stand-by diesel
generator with a new fuel oil fired generator, stainless steel
stack, supports and fuel oil supply system. To provide cooling
for the new diesel generator, a remotely located radiator along
with all the interconnecting cooling water piping and controls
were installed. To ensure emergency back-up generation during
construction of the new generator a 2MW temporary generator
was furnished.
