County Government Projects

Maryland Smart Energy Communities Grant Program
Maryland Energy Administration (MEA) launched the Maryland Smart Energy Communities program in 2013. The goal of the program is to have local governments commit to sustained energy savings and adopt policies related to energy efficiency, renewable energy and/or transportation efficiency.

The County received $649,000 to perform the following:
  • Purchasing 6 plug-in hybrid electric vehicles and install 3 dual-head electric vehicle charging stations at 9400 Peppercorn Drive.
  • Install a solar photovoltaic (PV) system at the Animal Shelter.
  • Install 11 energy-efficient HVAC systems at Rollingcrest Village, a senior citizen public housing complex.
Rooftop Solar Challenge Grant
The County received a technical assistance grant from the Department of Energy (DOE) via Metropolitan Washington Council of Governments (MWCOG) to develop and promote the Solar Road Map - a web tool that provides guidance on how to transform the local solar market by reducing "soft costs".

According to DOE, non-hardware costs or "soft costs" - including permitting, installation, and interconnection - can make up as much as 60% of the total installed cost of a rooftop PV system. The County in partnership with MWCOG is taking actions in four areas to bring down these soft costs and make is faster, easier, and cheaper to go solar:
  • Permitting and interconnection processes
  • Financing options
  • Planning and zoning
  • Net metering and interconnection standard
LED Outdoor Lighting Project - the Facilities, Operations & Management (FOM)
team replaced ~80 High Pressure Sodium (HPS) fixtures with energy-efficient LED fixtures in the parking lot area of Inglewood III and Largo Government Center.

LED fixtures use semi-conducting materials to convert electricity into light, which results in 35 - 60% energy savings, per light fixture. They last 3 to 4 times longer than traditional light sources, require less maintenance, and contain little to no hazardous materials.

The LED conversion project will save the County government approximately 121, 000 kWh and $13,000 in energy/operation costs annually. Additionally, the County received rebates from Pepco's Lighting Rebate Program to offset capital and installation costs.

Fleet Projects
Sustainable Fleet Projects
The County purchased 6 plug-in hybrid electric vehicles (PHEV) and 3 dual-head electric vehicle charging stations to "green" its fleet and reduce petroleum consumption. A PHEV utilizes an internal combustion engine, electric motor, and rechargeable battery that can be restored to full charge by connecting a plug to an external electric power. Compared to conventional vehicles, PHEV achieves almost double the fuel economy and produce lower carbon emissions.

In April 2013, the County placed into service 5 liquefied petroleum gas (LPG) powered vehicles. The Ford E350 vans are powered by Roush CleanTech propane autogas pumping station supplied by the County's contractor, Suburban Propane. Propane autogas is a clean-burning (produce 24% less carbon emissions), domestically-produced energy source, which costs about 50% less than gasoline.
Sunburst - Solar Photovoltaic Grant Program
The County received grant funding from the MEA to install 384 kW solar PV systems at the Consolidated Warehouse and Fleet Maintenance facilities. The County entered into a Power Purchase Agreement (PPA) with SunEdison, who designed, installed and maintains the system. It produces approximately 527,000 kWh of electricity and offset over 1.3 million pounds of carbon dioxide emissions annually.

Energy Performance Contracts
An Energy Performance Contract (EPC) provides customers with a comprehensive set of energy efficiency, renewable energy and/or distributed generation measures, accompanied with guarantees that the savings produced by a project will be sufficient to finance the full cost of the project.

The County Entered into EPCs with energy service companies Pepco and Johnson Controls, Inc., to perform energy and water improvements to 10 county government buildings. This project, known as Phase I EPC, generates approximately $1,000,000 of energy savings annually. The County plans to implement Phase II EPC for an additional 32 buildings over the next 5 years.

Energy Efficiency & Conservation Block Grant Projects
The County was awarded $6.6 million from DOE's Energy Efficiency and Conservation Block grant (EECBG) to reduce energy consumption county-wide. The County government used funding to develop the Energy Efficiency and Conservation Strategy, installed energy-efficient windows at Harriet Hunter Senior Center, and installed "cool roofs" at various county-owned buildings.

Landfill Gas-to-Energy Project
The Brown Station Road Sanitary Landfill is one of the first landfills in the Nation to operate landfill gas (LFG) fired electric generators. Four LFG fired electric generators and three boilers provide both power and steam to the County's correctional facility and auxiliary equipment at the landfill. The LFG-to-energy project generates approximately 25,000,000 kWh of renewable electricity annually (enough to power about 2,200 homes) and reduce approximately 17,730 metric tons of CO2 annually. Moreover, this project saves the County about $2,000,000 annually via the sale of surplus electricity to Pepco and from the on-site utilization of LFG to produce electricity in lieu of purchasing utility-supplied electricity.
