The company said that its distribution system reliability has been improving since 2004, primarily through identifying and focusing on circuits where interruptions are more frequent. Last year, Dominion Virginia Power reconditioned over 350 miles of electrical circuits, including installing more than 1,000 new poles, 3,500 new lightning arrestors and other devices.

Dominion has invested approximately $2 bn in recent years on advanced pollution-control equipment to reduce emissions and meet new environmental requirements. The company also claims that it has committed to meeting Virginia’s goal of achieving 15% of its electricity sales from renewable sources in 2025 and to reducing the growth in customer demand for electricity by 10% over the next 12 years.

To help meet the conservation goal, Dominion Virginia Power will begin offering new energy efficiency programmes this year to assist residential and business customers in saving energy and in helping to protect the environment.

Digital meters are being installed in some areas of Virginia as part of a demonstration project that will be expanded throughout the state if approved by the Virginia State Corporation Commission.
