Cynergy Electric Company, Inc.

Maryland Transportation Authority

Cynergy performed a circuit breaker, forced fan and fan controller replacement project with a contract value of $3.077 million at the Fort McHenry Tunnel for the Maryland Transportation Authority. The twelve existing double-ended substations are over 30 years old and fed the lighting, power circuits and ventilation fans in the East and West bound tunnels. Keeping the emergency circuits energized during the breaker and transformer upgrades was a critical part of the project. Only half of each substation was allowed to be completed at a time. Temporary circuits had to be installed from another substation to allow the critical circuits to remain in operation. The work had to be closely coordinated and monitored by the Authority during the entire replacement process.

Broad Creek Pump Station

Cynergy entered into an $11 million design-build contract with WSSC to provide two 2.5MW 2400 volt diesel powered generators in a brick/block building located in an historic neighborhood. The nature of the building’s occupants required a high level of security.

A 4MW temporary diesel power plant was provided prior to the beginning of construction to provide reliable standby power. The design challenges consisted of; limited space for the new building, building architectural features required satisfying the historical commission, 55dba noise ordinances and scheduling constraints. The new design is to provide sufficient generator capacity to provide back-up power for the entire facility. To accomplish this we had to provide two new 2.4KV 2500KW diesel powered generators, 8,000 gallon main fuel tank, two 275 gallon day tanks, vacuum breaker switchgear, neutral grounding resistors, intake and exhaust silencers, primary and secondary ultra quiet exhaust mufflers, wall mounted sound attenuated panels and sound attenuated building architectural features including doors, louvers, building exhaust systems, etc. The project was designed and constructed within 18 months.
