The Greensville 3x1 CC is expected to be the largest and most efficient in the U.S. 7

8. Atlantic coast pipeline
Project Overview
What is the Atlantic Coast Pipeline (ACP)?
A joint ownership venture with four energy companies to build an interstate natural gas transmission pipeline
Will serve the growing energy needs of Virginia & North Carolina
Why Build the Atlantic Coast Pipeline?
Cleaner energy for our customers and our community
Provides access to low-cost natural gas supply
Increases reliability & security of gas supply
Decreases nation’s dependence on foreign imports
Who will benefit from it?
Residential Customers
Customers with Businesses
Overall Economy in these States 8

9. Air Pollutant performance
Dramatic Reductions
Emission Rates of Sulfur Dioxide (SO2), Oxides of Nitrogen (NOx), and Mercury (Hg) have decreased even as power generation (demand) has increased since 2000. 9

10. CarBON PERFORMANCE
Continued Success
CO2 emissions intensity has decreased as generation increased (Includes divestitures) 10

13. Relicensing nuclear 2017 Nuclear Relicensing Cost Recovery Legislation
Supports Fuel Diversity
2017 Nuclear Relicensing Cost Recovery Legislation
License extension for North Anna & Surry to allow them to operate for the next 20 years -- currently scheduled to retire between 2032 and 2040.
Potential loss of existing zero-emitting nuclear would significantly complicate compliance with any carbon reduction program in the post-2030 timeframe.
To achieve electric output compatible with NA and Surry (3,346 MW) would require over 98,000 acres of solar panels (over 2 times the size of Richmond, VA) 13

14. Pumped Storage—SB 1418 2017 General Assembly
Declares one or more pumped storage hydro facilities in the coalfields region to be in the public interest:
Enjoys broad bipartisan support
Also declares associated renewable generation in the coalfields region to be in the public interest
Pumped storage is the only large-scale source of energy storage commercially available at present
Major economic development potential for Southwest Virginia 14
