Eastern Interconnection Grid Planning Completes Transmission Analyses and Initiates Study of Gas-Electric Interface
ST. LOUIS --(Business Wire)--
The Eastern Interconnection Planning Collaborative (EIPC) today
announced it has completed the transmission analyses as part of an
electric system transmission planning effort funded by the U.S.
Department of Energy (DOE).
"The EIPC has reached a major milestone with the completion of the
electric system transmission analyses of the stakeholder-defined
scenarios for the year 2030," said Stephen G. Whitley, president and CEO
of the New York Independent System Operator (NYISO) and chair of the
EIPC Executive Committee.
Stakeholders had defined three scenarios as part of the first phase of
the EIPC's studies. As a result of the scenario analyses conducted as a
part of the second phase, three future transmission systems were created
to support the chosen scenarios from a reliability perspective. In
addition, the capital costs to install the future resources assumed in
each scenario and the cost to install the supporting transmission
facilities were calculated along with the projected annual production
costs. Documentation of these results is included in a comprehensive
draft report on the study.
The three scenarios chosen by stakeholders are described in the report
Business as Usual: This scenario represents a continuation
of existing conditions, including load growth, existing Renewable
Portfolio Standards (RPSs) and proposed environmental regulations
as they were understood in the summer of 2011.
National RPS: State and Regional Implementation: This
scenario contemplates meeting 30 percent of the nation's
electricity requirements from renewable resources by 2030. This
would be achieved by utilizing a regional implementation strategy.
Combined Federal Climate and Energy Policy: This scenario
represents a combination of the following: a reduction of
economy-wide carbon emissions by 42 percent from 2005 levels in
2030 and 80 percent in 2050; meeting 30 percent of the nation's
electricity requirements from renewable resources by 2030; and
significant deployment of energy efficiency measures, demand
response, distributed generation, smart grid and other low-carbon
technologies. This scenario would be achieved by utilizing a
nationwide/eastern interconnection-wide implementation strategy.
The EIPC project team included transmission planning expertise from EIPC
members, stakeholder facilitators from The Keystone Center and technical
experts from Charles River Associates to support the capacity expansion
planning effort and production cost analyses.
The draft report from the second phase of the project is posted on the
EIPC website at: http://www.eipconline.com/Resource_Library.html.
Mr. Whitley added, "DOE has requested that we continue the project to
investigate if sufficient natural gas infrastructure exists to support
the growing use of natural gas for power production as well as the
associated impacts on electric transmission planning."
The effort to analyze the interface between the natural gas delivery
system and the electric transmission system has just begun and
supplements the ongoing work of the EIPC. EIPC will be continuing its
Eastern Interconnection-wide transmission planning activities in 2013
beginning with a comprehensive update of its Eastern Interconnection
power flow model for the years 2018 and 2023 based upon the regional
plans of its members. The natural gas study contemplates investigating
the increasing reliance on natural gas for generating electricity. The
expanding role of natural gas in the nation's power generation was
demonstrated in the capacity expansion analyses and production cost
studies completed in 2011 and 2012. The Federal Energy Regulatory
Commission (FERC), independent system operators (ISOs), regional
transmission organizations (RTOs), market participants and several state
regulatory commissions have raised concerns regarding the future ability
of the natural gas infrastructure to meet the coincidental requirements
of gas utilities and generators under various conditions, especially
during the winter heating season. The study will focus on areas of
particular concern, including the northeast and midwest regions of the
More information on the gas-electric interface study will be posted on
the EIPC website in the near future.
About the EIPC
Formed under an agreement by more than two dozen electric system
planning authorities from 39 states in the Eastern United States and two
provinces in Eastern Canada, the EIPC is focused on a "bottom-up"
approach, starting with a roll-up of the existing grid expansion plans
of electric system planning authorities in the Eastern Interconnection.
