What are MAPP's benefits?

The MAPP Project is consistent with multiple state and federal objectives. In addition to providing reliability and economic benefits to electricity consumers and distribution utilities throughout Maryland, Delaware and the region, MAPP will also foster the development of renewable resources, especially new wind generation resources.

Generally, there are four categories of benefits to construction of the MAPP Project:

• Reliability Benefits: The MAPP Project will provide a more reliable transmission infrastructure. 

• Economic Benefits: The MAPP Project will reduce transmission congestion in the Mid-Atlantic region and thus lower the cost of delivered power to electricity consumers throughout the Mid-Atlantic region. In addition, local counties in which construction occurs will receive annual tax revenue and during construction, MAPP will inject additional money into the local economy as per the table below.

• Renewable Generation Benefits: The MAPP Project will enhance the ability of existing and new wind resources being developed in the Midwest as well as off the shore of the Delmarva Peninsula to reach load centers throughout the region. The additional transmission access to these regions is imperative as utilities and electric suppliers seek to comply with states' Renewable Energy Portfolio Standards.

• Advanced Technology Benefits: The MAPP Project will rely on advanced technologies and the use of design and construction techniques for purposes of gaining efficiencies, improving operations and minimizing environmental impacts.

How much will it cost?

MAPP is projected to cost $1.2 billion and would be built in stages over several years.

Who will pay for this project?

The MAPP project was approved by the PJM Interconnection, the organization that coordinates the movement of electricity through all or parts of 13 eastern states and the District of Columbia. When PJM approves a new transmission line, customers throughout its territory share the cost. The MAPP line will benefit this region and will be paid for by the 58 million customers who reside in PJM's territory.

What charges are included in my bill?

Your electric bill includes a distribution, transmission, and supply charge.  The distribution charge is the cost of moving electricity from your local substation through power lines to your home or business.  There will be no changes to this portion of your bill due to MAPP. The transmission charge is the cost of moving electricity from the power plants and transmission tie points to your local substation. This portion of your bill will increase to pay for MAPP. The supply charge is a combination of energy and capacity charges. The energy charge is the cost to produce the electricity along with any transmission congestion incurred in delivering it. The capacity charge is the cost to have generation available to meet peak demand. The energy charge will decrease due to MAPP, while the capacity price will most likely not be affected.
