The PJM Interconnection Board May 17 approved nearly $2 billion in electric transmission upgrades that will maintain electric power supplies in the wake of plans to retire 14,000 MW of coal-fired generation between May 2012 and the end of 2015. The PJM region includes 60 million people in 13 states and the District of Columbia.
The PJM Board approved more than 130 transmission upgrades related to the generation retirements, ranging from equipment replacements to new substations to rebuilding existing transmission lines and building new lines. The upgrades will allow electricity to flow safely from other sources to replace the retiring generation.
PJM will announce the results of its annual capacity auction that will procure additional power supply resources including demand response and energy efficiency.
On a dollar basis, more than half of the improvements are in Ohio. The proposed retirement of generators along Lake Erie will require significant transmission upgrades in Ohio, particularly around Cleveland.
With the recent upgrades, the PJM Board has approved the investment of $23.4 billion in transmission additions and upgrades since 2000.
