Gas-Electric Study: 2012-2014

Subsequent to submitting the draft Phase II report at the end of 2012, the DOE noted the rapid changes in the natural gas market since the beginning of the study.  In particular, the discovery and development of new natural gas resources and the increasing reliance on natural gas for power generation raised a question about the sufficiency of the natural gas infrastructure to suppor the anticipated need for natural gas power productions in the future.  As such, the DOE provided the EIPC an extensionto perform additional technical analysis to evluate the interaction between the natural gas and electric systems.


This Gas-Electric System Interface Study is designed to provide analysis in sufficient detail to inform the planning, operations, and markets (where applicable) of the six EIPC Participating Planning Authorities (PPAs).  In order to evaluate the interaction between the natural gas and electric systems, the study has for main objectives (referred to as Targets):

  1. baseline the existing natural gas and elctric system infrastructure;
  2. evaluate the capability of the natural gas sytem to meet the needs of the electric system;
  3. identify contingencies on the natural gas system that could adversely affect electric system reliability and vice-versa; and
  4. review dual fuel capability.


As such, this study assumes adequate supplies of natural gas are available, and focuses on the interaction of the systems over the next 5 and 10 years in order to coordinate with existing planning authority timeframes, as well as credibly and accurately capture the significant change in generation resource fuel mix that will be occurring in the years 2015-2017 as a result of fuel economics and evnironmental regulations.


Levitan & Associates, Inc. (Boston, MA) was selected from six consulting organizations that submitted bids to lead the technical analysis for the Gas-Electric System Interface Study.  The PPAs completed an extensive review process of each proposal received and concluded that Levitan & Associates would bring the best technical and managerial resources to perform the analysis.


As for the Phase I and Phase II work, stakeholder involvement is provided thorugh the Stakeholder Study Committee (SSC), expanded to include representatives from the gas industry, with additional involvement of stakeholders through PPA regional process as described in Stakholder Process Enhancements for the EIPC Gas-Electric System-Interface Study (06/06/2013).

Project Overview

Disclaimer:  References to the DOE-funded study reports and other documents, including the Phase 1, Phase 2, and Gas-Electric Study Reports, contained in any independent study or publication do not constitute or imply endorsement or recommendation by the EIPC.

The EIPC was awarded funding from the U.S. Department of Energy (DOE) in 2010 to prepare analysis of transmissin requirement under a broad range of alternative futures and develop long-term interconection-wide transmission expansion plans in response to the alternative resource scenarios. 


The DOE funding enabled EIPC to perform analysis and planning for the Eastern Interconnection in a transparent and collaborative manner, open to participation by state and federal officials, representatives from independent system operators (ISOs) and regional transmission organizations (RTOs), utilities, and relevant stakeholder bodies or non-government organization (NGOs), including appropriate entities in Canada, with an approach to ensure consensus among stakeholders on key issues.

Initial Study Work: 2010-2012

This work was divided into two phases.  The work for Phase I, lasting from 2010 to 2011, consisted of aggregating regional transmission expansion plans into a Roll-Up Report, performing interrgional analysis, and conducting macroeconomic analysis on 8 Futures.  Phase II, from 2011 to 2012, analyzed three transmission scenarios, including reliability and production cost modeling of alternate transmission options.  During this period the participating EIPC members were assisted by the Keystone Cneter and by Charles River Associates.
