Substation Construction Page

From station upgrades and expansions to Greenfield 115- and 345KV substation construction, Mass Bay has participated in a wide range of substation projects over the past fifteen years. All of our completed engagements showcase our commitment to quality work and reliability. We go beyond construction basics, playing an active role in all phases of the EPC process, and offer the flexibility needed to manage the complexities of unforeseen conditions and changes in the face of set outage schedules.

We are experts in 345kV and 115kV transmission class and distribution class construction, primarily focused on:

Static VAR compensators
Shunt reactor assembly
Grounding systems
Swaged and welded overhead bus assembly
Strain bus installation
Autotransformer assembly
Gas circuit breaker assembly
Control and protection systems construction
ROW to Station line connections
Station underground infrastructure
Underground distribution get-away circuits

As an alternative to conventional “Stick built” station construction, Mass Bay has
also partnered with a manufacturer of skid-mounted station components. This method
of construction allows for shortened installation times, ultimately reducing cost and
outage durations.
