Energy Performance Contracting
DGS works with State agencies to substantially reduce Maryland's government energy consumption. During the O'Malley/Brown Administration the Board of Public Works has approved 21 Energy Performance Contract (EPCs) projects. To date these projects are helping Maryland achieve contractually guaranteed energy and operational savings of approximately $310 million to be realized throughout the life of the contract).
- Cost Savings: $21.3 Million annually
- Greenhouse Gas Savings: 130,000 tons of CO2 annually
At Spring Grove Hospital Center, energy conservation measures under an EPC completed in January 2010, have provided confirmed avoided utility costs of more than $5.5 million, nearly $1.4 million in excess of the guarantee over that period.
DGS purchases electricity in de-regulated power markets on behalf of all Executive Agencies. Through an innovative electricity purchasing strategy for the larger accounts, DGS hedges for a portion of the future power requirements for State sites. By locking in rates for a portion of future power needs and purchasing the balance at real time rates, favorable trends in power prices are exploited to the State's benefit. DGS works with the University System of Maryland to achieve savings compared to comparable fixed price contracts.
- Cost Savings: $10.8 Million in FY13
DGS continues to purchase electricity for the State's several thousand smaller accounts through periodic online reverse auctions. The first such auction was conducted in 2004. The most recent auction was conducted in May 2011. The next auction is scheduled for mid-2014.
State Energy Database
DGS manages the State utility database. This web-based, utility management system holds approximately 22,700 State utility accounts including electricity, gas, water, steam, chilled water, and fuel oil. DGS has established a baseline year of FY08. The database provides access, accountability and trackability for all State Agencies energy use and is accessible to the public.
- State FY13 total utility expenditure: $219 Million
Electricity Demand Response
DGS, Towson University, University of Maryland Baltimore, Maryland Aviation Administration, University of Maryland College Park, University of Maryland Baltimore County, Maryland Department of Veterans Affairs and Maryland Stadium Authority are participants in a demand response program. The program allows the entities to manage peak energy demand by reducing consumption at critical summer days.
- Since 2008, the State Center Complex has received about $972,000 in net payments for program participation.
DGS currently has Solar PV panels on four DGS buildings generate 432 kW (520,000 kWh/Year)
- Tawes State Office Building (4 Buildings) -580 Taylor Avenue. Annapolis - 126 kW
- John R. Hargrove, Sr. DC & MS Center -700 E. Patapsco Ave. Baltimore - 106 kW

- Ellicott City DC & MS Center -3451 Courthouse Dr. Ellicott City - 126 kW
Maryland State Agencies have Solar PV Panels generating 1.75 MW (2,943,360 kWh/Year)
- Maryland Aviation Administration – Thurgood Marshall/BWI Airport 0.5 MW
- Maryland Transit Administration – 0.5 MW
- Maryland Port Administration – 0.75 MW
Generating Clean Horizons
A program managed by DGS & USM assists with the States' renewable energy portfolio, by purchasing electricity from three large scale wind and solar installations. DGS works with State agencies in the development and implementation of additional renewable projects throughout the State.
These contracts are with the following entities:
- Mount St.Mary's Solar – 13 MW of Solar generated power for 12,968 MWh/year. Delivery began July 2012
- Roth Rock Wind – 10 MW of Wind generated power for an annual 30,605 MWh/year. Delivery began August in 2011
- Pinnacle - 55.2 MW of Wind generated power for an annual 173,542 MWh/year. Delivery began December 2011
