Analysis of Need for Proposed Transmission Line

Pennsylvania Office of Consumer Advocate
Completed May 2008

Synapse and Lanzalotta Associates analyzed the proposed $1 billion TrAIL 500 kV transmission line from southwestern Pennsylvania to northern Virginia for the Pennsylvania Office of Consumer Advocate. Their findings included recommendations to implement energy efficiency and demand response in the West Penn Power service territory of Allegheny Power to reduce local loading, and to reinforce the 138 kV system in the area, instead of building one portion of the proposed line, the segment between 502 Junction and Prexy in PA. The findings also included a recommendation for more rigorous analysis of the overall need for the remaining portion of the line between 502 Junction and Loudoun (No. VA), given PJM’s minimal analysis of the effect of federal CO2 regulation on the claimed PJM dispatch efficiencies and production cost savings associated with the line.
