The Eastern Interconnection Planning Collaborative (EIPC) has completed the transmission analyses as part of an electric system transmission planning effort funded by the U.S. Department of Energy.

"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,” says Stephen G. Whitley, president and CEO of the New York Independent System Operator 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.

The three scenarios chosen by stakeholders are described in the report as follows:

Business as usual: This scenario represents a continuation of existing conditions, including load growth, existing renewable portfolio standards (RPS) and proposed environmental regulations as they were understood in the summer of 2011.

National RPS - state and regional implementation: This scenario contemplates meeting 30% 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 a reduction of economy-wide carbon emissions by 42% from 2005 levels in 2030 and 80% in 2050; meeting 30% 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 work 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.

EIPC will continue its Eastern Interconnection-wide transmission planning activities this year, 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.
