A Unique Location Industrial Area 4 Luck Stone Quarry Overlay Loudoun Water Treatment Plant (future) Leesburg Airport Noise overlay Electrical transmission lines Gas Transmission Lines

5 Existing Resources Two underground natural gas lines on site. Lines from the Gulf Coast, Ohio Valley and liquid natural gas port. Redundancy allows a unique facility that will not need to burn oil or diesel. Natural Gas Transmission Two 230 KV and One 500KV Electrical transmission Lines North/South and East/West Transmission Distribution Between two major substations serving Loudoun County Electrical Transmission Lines

What Are We Proposing? 6 Combined Cycle (Natural Gas and Steam) generator. Natural Gas peak energy generation. Virginia’s Largest Solar array. Wastewater effluent re-use. Best Available Technology facility. Low Stack Design.

Benefits Transition off of coal. Electrical generation near demand. Puts Loudoun in forefront of renewable energy by constructing Virginia’s largest solar array. Unique Economic Development Opportunities. Significant annual tax revenue to Loudoun County. Educational Opportunities. Energy reliability for the Local Community. Reduces energy importation. 7

8 Economic Impact No taxpayer-funded infrastructure costs. Up to $12 million in annual local tax revenue and 25 permanent jobs. Creates 1,200 jobs and $183 million in indirect benefit to Loudoun County’s economy during the three years of construction. A recurring multi-million dollar benefit to Loudoun County’s tax base. ~ Churma Economics & Analytics,“The Economic and Fiscal Benefit of a Proposed Energy Generating Plant in Loudoun County, VA.” November 12, 2009

9 Environmental Air Quality - Best Available Control Technology Water Quality - Chesapeake Bay cleanup BMP/LID – 81% of the site is porous Wetlands - No onsite impacts Very Steep Slopes - No Onsite Impacts Noise - Sound Attenuation conditions of approval Visual - Low profile, topographically concealed Forest Resources - Replacing low quality area with high quality reforestation

Air Quality “This plant will be designed with the most advanced air pollution control technology to reduce air discharges as any plant in the [United States], western Europe or Japan. This control system is deemed to be the best technology available by the US EPA and the South Coast Air Quality management District in Los Angeles, CA (considered by many to be the premier regulatory agency for controlling smog in the US).” ~ MACTEC,“Revised Air Quality Study of Green Energy Partners/Stonewall Solar and Natural Gas-Fired Power Plant at Leesburg VA,” November 20,

11 Compliance with DEQ permitting requirements: Frequency of Monitoring: Monthly for first three years to establish baseline. Potentially quarterly thereafter, dependent upon baseline data. Monitoring Program: Toxicity Flow pH Temperature Dissolved Oxygen Copper, Iron, Chloride, Hardness Oil and Grease Chemical Oxygen Demand Total Petroleum Hydrocarbons Other parameters deemed necessary as part of the permit process On-Site Water Quality Monitoring

Cleaning up the Bay Re-using 2 billion gallons per year of Leesburg’s waste water. Using treated effluent removes nitrates and phosphates from the Potomac River and the Chesapeake Bay. Zero discharge of water reuse from the energy plant into streams. 12

Plume Abatement Visible plume is caused by ambient conditions of low temperature and high humidity Visible Plume Abatement reduces the visible plume by adding hot dry air to the saturated air leaving the cooling tower Abatement included in Conditions of Approval 13

GEP vs. Coal  GEP can displace coal power with clean Natural Gas.  Coal plants are the biggest mercury contributors to the environment. Approximately 1,100 such units at more than 450 existing power plants emit 48 tons of mercury into the air each year. They also release arsenic, lead, aluminum, antimony, arsenic, barium, beryllium, cadmium, calcium, chromium, cobalt, copper, iron, lead, magnesium, manganese, mercury, molybdenum, nickel, potassium, selenium, silver, sodium, strontium, tin, vanadium and zinc, all of which are considered hazardous to the environment.  New combined cycle power facilities decrease emission rates for mercury and other heavy metals by 100 %, sulfur- dioxides by nearly 100 % and nitrogen oxides by more than 95%. 14

Impacts on Energy Supply “In all of the system models that were studied the Green Energy Partners … proposed …generator resulted in a large reduction (between 18% and 21%) in reliance on external power to be delivered through the transmission system to serve the load in the Loudoun County and Leesburg area.” 15 ~ PowerGEM, “Leesburg Generation Study “ (7/7/09)

Costs of Energy in Loudoun 16 As demand increases and without additional supplies, energy prices rise. Creating energy where it’s needed reduces cost. Increases Passed on to Users: NOVEC 62% (‘02-’08) Dominion Power 18% (2008)

FAA Approved The Federal Aviation Administration issued a “Determination of No Hazard to Air Navigation.” “The aeronautical study revealed that the structure does not exceed obstruction standards and would not be a hazard to air navigation. …” ~ Aeuronautical Study No AEA-2612-GE 19

National Security 20 A diversified, centralized and efficient energy system around our nation’s capital. Forecasted long-term growth in energy demand. New efficient generation will keep costs down. “… the geographical dispersion of generators not only improves their overall reliability, it makes the entire distribution network more secure and resilient to accidental power disruption, systems failure, or intentional attack. … The U.S. government has also acknowledged the ability of renewable distributed generation to deter major power outages and provide consistent power supply.” ~ Benjamin K. Sovacool on behalf of the Piedmont Environmental Council before the State Corporation Commission of Virginia.
