Energy System Group

Scope Of Work

The Maryland Transportation Authority (MDTA) operates all of the bridges, tunnels and toll plazas across the State of Maryland. Since 1971, the MDTA has been responsible for constructing, managing, operating, and improving the State’s toll facilities, as well as for financing new revenue-producing transportation projects. The MDTA’s eight toll facilities, two tunnels and four bridges help keep traffic moving in Maryland. The MDTA selected Energy Systems Group (ESG), a specialized energy services and performance contracting company (ESCO), to complete over $8.6 million of infrastructure upgrades and comprehensive energy conservation measures in 46 buildings at eight locations statewide. These measures and improvements will result in energy savings of $640,000 annually and a reduction in maintenance costs of $184,000 annually.

The energy conservation measures and infrastructure improvements developed by ESG included advanced-technology LED lighting that will replace existing sign lights throughout the State, including the Bay Bridge. The facility improvements included new boilers, expanded HVAC DDC controls, upgraded lighting and associated controls, solar heating photovoltaic system, water conservation, and building envelope upgrades.
