Gas-Electric System Interface Study
• Participating Planning Authorities (PPAs) are: ISONE,
NYISO, PJM, IESO (Ontario, Canada), MISO (including
the Entergy system), and TVA
• Four Targets (areas to be analyzed)
• Most analytical work to be completed by a
consultant with gas industry expertise
• Stakeholder process:
– Regional stakeholder groups from each PPA
– Interconnection-wide Stakeholder Steering Committee
(SSC) continues from earlier work
– Gas Sector added to SSC with pipeline, supplier, and LDC
representatives
3
Target 1
• Develop a baseline assessment that includes
descriptions of the natural gas-electric system
interface(s) and how they impact each other
– Utilize public information and other appropriate sources
of data
– Develop a baseline of the natural gas and electric systems
interface(s) within each PPA Area and the entire Study
Region
– Assess the specific drivers of the planning process for
each of the major pipelines/LDCs in the Study Region
4
Target 2
• Evaluate the capability of the natural gas system(s)
to supply the individual and aggregate fuel
requirements from the electric power sector
– By each PPA Area and for the overall Study Region
– 5 and 10 year study horizon
– Reference Gas Demand Case and a High Gas Demand
Case
– Subject to funding availability, the same for a Low Gas
Demand Case or a different scenario
– Subject to funding availability, sensitivities defined by
stakeholders
5
Target 3
• Identify contingencies on the natural gas system
that could adversely affect electric system reliability
and vice versa
– By each PPA Area and for the overall Study Region
– 5 and 10 year study horizon
– Subject to funding availability, the same for a High Gas
Demand Case
– Subject to funding availability, the same for a Low Gas
Demand Case or a different scenario
6
Target 4
• Review operational and planning issues and any
changes in planning analysis and operations that
may be impacted by the availability or nonavailability of dual fuel capability at generating units
– Review the benefits and costs of requiring dual fuel
capacity versus the benefits and costs of gas sector
infrastructure expansion
– Review of the siting and/or permitting issues that might
affect the feasibility of one solution over the other (e.g.
dual fuel versus gas system expansion), or possibly drive
an alternative solution
