• Dominion has several LEED Certified buildings– The administrative building at our Cove Point LNG facility in Maryland is LEED silver

certified. LEED certification is in the current project scope for Cove Point expansion project buildings.

– The Sabinsville office building in north central Pennsylvania is LEED gold certified.– The administration and warehouse building at our Warren and Brunswick combined

cycle power plants are being constructed to LEED standards.

• Examples of LEED Measures at Sabinsville:– Natural daylight through use of skylights– Triple-pane operable windows– Cellulose insulation (made from recycled newspaper) that increases energy efficiency– Low-flow plumbing fixtures– Highly efficient heating, ventilating and air conditioning (HVAC)– Low VOC (Volatile Organic Compounds) finishes– Recycled stone veneer and siding– Occupancy and daylight sensors to help reduce electricity use,

efficient light fixtures– Landscaping with native plant species that require no irrigation once established

• Future Community Solar Distributed Generation (DG) Program– Distributed Generation (DG) is the concept of decentralized, local energy

production often utilizing wind and/or solar– Solar DG penetration is rapidly increasing across the country– Dominion has received approval for a Community Solar Program

− 30 MW of utility-owned distributed solar on leased roof space− Tariff to purchase output from customer-owned solar DG installations

Source: Southern California Edison 23

• Solar resources are becoming more cost competitive− Rapidly dropping costs of solar modules− Standardization of installation− Federal tax credits available to January 1, 2017

• However, solar PV is not dispatchable and contributes less to peak load and reserve requirements than conventional resources• Dominion is constructing a 7.7. MW solar

generating facility in Georgia.

24

Challenges• Costs

– Renewable generation is more costly when compared with conventional sources

– Virginia’s low electric rates make renewable generation even less competitive

• Intermittency• Regulatory approval process

geared towards centralized, large-scale projects

Opportunities• A more balanced, diverse

fuel supply for our customers

• Satisfaction of Virginia’s voluntary renewable goals

• Additional economic development through creation of jobs and tax revenue

• Improvement of technology via practical usage

25

• In 2007, Virginia passed into law a voluntary Renewable Portfolio Standard (RPS):

• Dominion is growing its renewable portfolio to reach 15% by 2025• Evaluating all available options to meet targets

– Existing utility-owned renewable generation– Build new renewable facilities in Virginia– Purchase Renewable Energy Credits (RECs)

• North Carolina RPS requirements

26

• Residential programs include:– Air Conditioner Cycling – Low-Income Audit – Residential Bundle

• Home Energy Check-Up• Residential Duct Testing & Sealing• Heat Pump Tune-Up • Heat Pump Upgrade

• Commercial programs include:– Commercial Audit– Commercial Duct Testing & Sealing – Commercial Distributed Generation

28

• Energy assistance programs– EnergyShare program provides heating and cooling assistance to those in financial need in Virginia and heating assistance in North Carolina and Ohio

• Funds come from Dominion, stockholders, employees and customers

Save Pleasure House Point!• Community investment program− Preserving Pleasure House Point

• In December 2011, the Dominion Foundation provided the Trust for Public Land with a $500,000 grant toward the purchase of Pleasure House Point in Virginia Beach, VA

• Pleasure House Point is a 122-acre tract of undeveloped land between the Lynnhaven River and the Chesapeake Bay

• The Virginia Beach City Council on December 11, 2012, voted to approve a Conditional Use Permit for the Chesapeake Bay Foundation (CBF) to construct what will be the most environmentally sustainable building in Virginia, located at Pleasure House Point.

• Engaging stakeholders– Corporate Social Responsibility/Sustainability Report– IRP Stakeholder process– In 2012, Governor McDonnell hosted a round table

discussion on Corporate Sustainability – Dominion participated.

– Jointed VMA’s Sustaining Virginia program, EPA’s Natural Gas Star program (DTI), EPRI Sustainability Interest Group, Arbor Day Foundation’s Tree Line USA program (DVP)

– Created sustainability@dom.com– Completed Water Carbon Disclosure Project survey

and added of water metrics to www.dom.com

April 2012: Round table discussion with Governor McDonnell

• Engaging our employees– Created Director of Sustainability position,

Staff Level Sustainability Team, Executive Sustainability Council

– Pre-existing Nuclear Green Team– Created sustainability@dom.com– Created a Sustainability Speaker Series– Published multiple internal articles for

employees on sustainability– Developed employee energy audit team
