Potential downward pressure on emissions, increasing CAFE standards, reductions in incremental cost, advancing battery technology, availability of tax incentives, and higher gasoline prices may provide
sustainable support for manufacturers
Electric Vehicles: Approximately 35 New Models by 2013

Electric Vehicles: Proposed EV Pilot Program
Pilot program offering time-of-use pricing options DVP hopes to learn about the EV penetration, customer’s
charging patterns, and impacts on the grid Supports customers’ adoption of EVs while attempting to
minimize grid modifications by encouraging off-peak charging – EV-only rate: 35 cents/night for 40-mile commute – Whole-house rate: 33-41 cents/night for 40-mile commute – Compares to 86 cents/night using standard residential rate – Up to 750 participants in each rate option

National cumulative growth trend indicates growing strong market interest in this sector – Tax credits available through
2016 for solar and small wind <100 kw
Significant growth in DVP Net-Metered Systems in 2010 – Total installed capacity is greater
than 2 MW – 330% annual increase from 2009 to
2010

Commonwealth of Virginia Legislation: HB 1686 - Solar DG Demonstrations – Authorizes SCC to approve petitions for:
• Utility-owned solar DG • Special tariffs to facilitate customer-owned solar DG
– Dominion intends to file for approximately 30 MWs of utility-owned DG

Offshore Wind Generation
Potentially one of the largest sources of renewable, carbon-free energy in Virginia
More costly to install and maintain
than onshore wind
DOE grant to look at ways to reduce the cost

Dominion’s Solar with Integrated Battery Project
4 MW ground-mounted solar photovoltaic project in Halifax County 12.5 MW hrs of nickel-iron battery storage
Battery chemistry first developed by Edison in mid-1800’s Long shelf life and slow discharge rate
Dimensions: 40’x 61’ Battery Array Weight: 264,240 lbs Capacity: 12.5 MWH Voltage: 48V
Objective to test the integration of solar and battery storage on Dominion’s system
Gap exists between solar peak and utility’s peak load
