  • Reduce costs to customers by ensuring accuracy of Company equipment, such as remote meter reads
  • Manage maintenance schedules to maintain the reliability and integrity of Dominion’s natural gas pipeline
  • Improve generating efficiency and equipment reliability to minimize emissions and hold down electricity costs
