“We can respond essentially in two ways: we can add more capacity through new generation or transmission, or we can reduce amount of electricity we use. At the end of the day, we will need to do some of both.”

Maryland Public Service Commission Interim Report to the Maryland General Assembly December 2007


PROJECT BENEFITS

Much of the East Coast relies on a congested power system that does not have enough capacity to meet rising demand. In Pepco Holdings, Inc.’s (PHI) service territories, demand for power during peak usage times is projected to increase by nearly 20 percent over the next 10 years. This demand is significantly greater than the increases in power that we will be able to supply if we do not build new transmission infrastructure to reduce congestion.  

Growing Demand for Electricity

Increase in energy demand is the result of many factors including population growth and increased individual electricity consumption. Currently, it is estimated that one megawatt (MW) of electricity can power approximately 700 homes.

To supply the energy that the region needs, MAPP will:

  • Improve the flow of electricity throughout the eastern Mid-Atlantic region
  • Increase the region’s power import capabilities
  • Connect numerous points on the grid that are currently underserved
  • Enhance local power distribution systems through multiple upgrades
  • Provide a pathway for clean, renewable energy (such as wind and solar power)
    to move across the region
  • Support additional transmission which encourages economic growth
  • Begin improving transmission in as little as five years after starting construction
  • Benefits all utilities in the region including co-ops and municipals

MAPP will produce many benefits for PHI’s service territories and neighboring utilities. The transmission line is designed to improve electricity transmission capacity, support new power generation, enhance reliability and provide access to more distant and economical sources of electricity during peak demand. MAPP will also provide the additional infrastructure needed to support proposed clean energy projects in the Mid-Atlantic region, such as new nuclear and wind. It also will complement states’ energy efficiency and demand side management initiatives.
