The PJM Interconnection Board has approved $1.8 billion in electric transmission system additions and upgrades for the grid. The improvements will enhance the reliability of the power supply system serving 51 million people in 13 states and the District of Columbia.
The PJM Board has authorized a cumulative $11.6 billion in transmission improvements since 2000, when PJM's first regional transmission expansion plan (RTEP) was approved. The current authorized upgrades and improvements are comprised of dozens of projects within most of PJM's transmission zones. Most of the new projects are forecast to be less than $50 million in investment individually.
‘With the increasing importance of transmission infrastructure in facilitating solutions for our future energy needs, it is critical to have a robust transmission system,’ says said Terry Boston, PJM's president and CEO. ‘Once again, by working with the stakeholders, we have identified improvements that will mitigate potential reliability threats.’
There are almost 96,000 MW of proposed new generation under development through the interconnection process, with 8,300 MW of projects under construction. Since the RTEP process began, more than 19,000 MW of new generation has been connected to the grid. Since February – when the last major upgrades were authorized – PJM completed 82 interconnection system impact studies that identify the upgrades required to reliably integrate new interconnections to the PJM system. During the past year, 73 proposed interconnection projects were withdrawn. The net increase in the RTEP with new and withdrawn generation projects is $349 million.
System upgrades were authorized for the transmission zones of Atlantic Electric, Baltimore Gas and Electric, Delmarva Power and Light, MetEd, PECO Energy, Penelec, Pepco, PPL, PSE&G, Jersey Central Power and Light, American Electric Power, Allegheny Power System, Commonwealth Edison and Dominion Virginia Power.
