Eastern Interconnection Planning Collaborative Releases Technical Analysis as Part of Gas-Electric Studies

Preliminary findings from an Eastern Interconnection Planning Collaborative study show that gas pipeline infrastructure in eastern PJM may be moderately constrained for the 2018 and 2023 winter peak demand periods. The findings also suggest that dual-fuel capability could help mitigate the potential loss of natural gas service to affected generating units.

The Target 3 findings are among four sets of EIPC target studies examining the gas-electric system across a large portion of the Eastern Interconnection. PJM, ISO New England, the New York Independent System Operator, Mid-Continent Independent System Operator, Tennessee Valley Authority and the Independent Electricity System Operator of Ontario are participating in the studies as part of the EIPC.

Target 3 focused on identifying natural gas system contingencies that could impact electric system reliability, and vice versa. The third target study relies on the results of the earlier Target 2 study to identify electric and gas infrastructure and market contingencies with a high potential to disrupt gas deliveries to electric generators. For each identified gas- and electric-side contingency, potential solutions and mitigation measures are being identified.

The study began in 2013 as a request from the U.S. Department of Energy and is expected to be completed in mid-2015. The other three targets of the study are: establishing a baseline of existing natural gas and electric system infrastructure; evaluating the capability of the natural gas system to meet electric system needs; and evaluating the costs/benefits of, and issues associated with, generator dual-fuel capability.
