Economic planning

ATC utilizes three methods to determine which projects have the potential for economic benefits:

  1. Stakeholder Input and Analyses (FERC Order 890)
  2. Reliability Project Screening
  3. Congestion Severity Index

These methods are described below.

Stakeholder Input and Analyses

In March 2008, Federal Energy Regulatory Commission (FERC) Order 890-A took effect. As part of this order, FERC requires a coordinated, open, and transparent transmission planning process on both a local and regional level. To comply with these requirements, ATC submitted a compliance filing on Order 890-A that provides a timeline of actions to ensure that the economic planning process is both coordinated and open.

Annually, ATC will use a process with consistent timelines that combines stakeholder input, historical data, future line flow forecasts, and updated information on the electric system to identify transmission upgrades for economic evaluation.

Each year:

  • During February, we hold an initial stakeholder meeting to review the market congestion summary and potential fixes and to discuss economic study scenarios, drivers, ranges, and assumptions.
  • By March 1, we work with stakeholders to request and prioritize new/other economic studies and recommend study assumptions.
  • By April 15 – we identify preliminary areas of economic study, study assumptions and models and solicit further comments from stakeholders.
  • By May 15 – we finalize areas of economic study, study assumptions and models to be used in analysis.
  • By November 15 – we provide a summary of the results of the economic analyses to our stakeholders.

ATC conducts analyses of the projects identified for study over several months’ time and posts the key results, including the extent to which these savings offset project costs. When the expected benefits of a studied project are high enough to justify its costs, the process of developing it as a formal proposal is begun.

As a result of the 2012 ATC/stakeholder collaborative process, we are performing economic analyses on the following ATC facilities:

Order 890 Economic Studies
  • Saratoga – Petenwell Area
  • Granville – Butler – Bluemound – St. Martins – Oak Creek Area

Studies will be performed and results shared with stakeholders over the course of the year. In addition, customers and stakeholders who would like to request specific economic studies can do so if they are willing to pay for the studies and are willing to have the results posted publicly.

Reliability Project Screening

Economic analyses were performed on 20 projects from the 2011 10-Year Assessment project list to determine whether those projects were candidates for acceleration or deferral based on economic considerations. Please refer Table EP-1 for the list of projects screened. The list of 20 projects was based primarily on the availability of redispatch and capital costs of the projects; however, lower cost projects specifically identified by the ATC planning department were also included in the study. Generation interconnection and distribution interconnection projects were not eligible for inclusion in this list. Further, capacitor bank projects were not considered since the voltage benefits provided were not captured by the PROMOD software analysis.  Finally, projects with in-service dates prior to 2014 were not considered since development of those projects was too far underway to make scheduling changes. As a result of this screening, one project was identified as having potential economic benefits and a candidate for acceleration of the original in-service date. It is project 14 from Table EP-1:  Constructing a 345/138kV transformer at a new 345kV North Randolph bus and looping the Columbia to South Fond du Lac 345kV line into it.

A similar analysis will be performed in the 2013 10-Year Assessment based upon the 2012 Assessment project list.

Congestion Severity Index

ATC developed a Congestion Severity Index for use as the screening indicator to track locations on the transmission system where constraints to the delivery of economic energy exist.  The Congestion Severity Index combines the financial impact of constraints with the frequency of constraints.  The financial impact during an hour is the calculated theoretical maximum number of dollars that could be paid into the market due to congestion on the constraint in question.  The sum of the total financial impacts for each hour during which the constraint occurs forms the basis of the Congestion Severity Index.  This information is used as a starting point in determining areas of the system where potential upgrades may be cost-effective.  This data is combined with stakeholder input and ATC planning recommendations to identify a group of projects to study. A list of the most severe market constraints in the Day Ahead and Real Time markets for 2011 is given in Tables ZS-5 and ZS-6, respectively. Maps depicting the geographic locations of the most severe market constraints in the Day Ahead and Real Time markets for 2011 are shown in Figure ZS-27 and Figure ZS-28, respectively.

This document details the preliminary drivers and assumptions that ATC is planning to utilize for the 2013 PROMOD development and analysis.

ATC Potential Economic Study Area

This document details the several potential study areas ATC is considering for economic analysis as part of the 2013 Economic Planning process.

Public Policy Requirements

In addition to potential studies area linked to market congestion, ATC is also seeking feedback in areas where Public Policy Requirements may drive transmission needs. Public Policy Requirements are enacted statutes (i.e., passed by the legislature and signed by the executive) and regulations promulgated by a relevant jurisdiction, whether within a state or at the federal level, including duly enacted laws or regulations passed by a local governmental entity, such as a municipal or county government.  Stakeholders are encouraged to provide ATC with Public Policy Requirements.  ATC utilizes transmission needs driven by Public Policy Requirements in its assumptions when performing economic analysis of study areas.  The transmission needs driven by Public Policy Requirements that will be included in ATC’s finalized assumptions will be posted prior to May 15th.

We look forward to your involvement in this process and appreciate your input and feedback as we proceed with our 2013 TYA and Economic Planning process.  We will continue to work with you and plan to finalize our economic analysis plan and assumptions by May 15, 2013.
