Interregional Planning

Finding common ground

America can benefit from delivering the Midwest’s cost-effective and abundant renewable energy resources.  We work with MISO to find common ground among multiple stakeholder groups to get transmission planned and approved between Regional Transmission Organizations (RTOs) and develop effective policies for delivering electricity between multiple RTOs.  

MISO has some of the best wind resources in the world and best solar resources in the country.  Our country can benefit from cost-effective delivery of these resources between and among Regional Transmission Organizations (RTOs).  Clean Grid Alliance’s technical and policy expertise helps identify drivers of new transmission and finds common ground among disparate stakeholders for getting interregional transmission planned and approved.  Clean Grid Alliance also leverages its relationships with stakeholders -- such as wind and solar developers, transmission organizations, utilities, competitive transmission developers, environmental advocates that support renewable energy and local consumer advocates -- to develop effective policies that meet the needs of both or multiple RTOs. 

In 2011 FERC issued Order No. 1000, which reformed the FERC’s electric transmission planning and cost allocation requirements for public utility transmission providers.  One of the reforms establishes a framework for neighboring transmission planning regions (e.g. RTOs and ISO’s) to improve their coordination in approving new interregional transmission facilities.  FERC, in Order No. 1000, intentionally kept aspects of interregional planning soft[1], giving deference to the experience of RTOs in transmission planning and to see how much progress the transmission planning organizations can make on their own.  After five years of work and two amendments to the initial Order No. 1000, renewable advocates recognize that interregional planning and its resulting projects have potential merit, but that RTOs need further guidance on how to focus on valuable transmission solutions that address long-term market uncertainties.

MISO’s interregional planning process is memorialized in MISO’s Attachment FF and through Joint Operating Agreements that MISO has with Southwest Power Pool, and with PJM Interconnection LLC.  Planning is conducted through Interregional Planning Stakeholder Advisory Committees (IPSAC) that MISO has with each of the three transmission planning organizations MISO coordinates with.  The IPSAC is an open stakeholder group that provides input to MISO and its neighboring transmission planning organization regarding the development of coordinated system plans (CSP).  The CSP identifies transmission issues and resolutions that benefit both MISO and the neighboring RTO.  The CSP is conducted jointly between MISO and Southwest Power Pool, MISO and PJM Interconnection LLC, MISO and Southeast Regional Transmission Planning.  This collaboration between MISO and three of its neighbors is intended to improve the efficiency of delivering electricity on an interregional/inter-RTO basis, is to be proactive and well-coordinated.
