WATSON GENERATING STATION

Braintree, Massachusetts

MEC was the prime electrical subcontractor for this 116-MW generating station built on 2 acres of land adjacent to an existing power plant. Two 50-MW gas turbine generators connected to two 70-MVA transformers (GSUs) — all owner-supplied — feed the power grid at 115kV.

MEC’s work included installation of:

• 15kV switches
• Service station transformers
• Medium-voltage starters for gas compressors
• Four 480V switchgear motor control centers
• Structure to house the electrical equipment
• All conduit and wiring (extensive duct banks)
• Ancillary electrical equipment
