ATC Major Projects Update

Wisconsin Industrial Energy Group

August 9, 2007

Madison, WI

Flora Flygt, Director of System Planning

Franc Fennessy, Manager of Local Relations


Access Initiative

  • Goal: Reduce delivered cost of energy to Wisconsin consumers by . . .

    • reducing system congestion

    • improving access to additional energy sources

  • Solution: Add an additional 345 kV circuit to the existing 345 kV line (W4) between Rockdale SS (Dane) and Paddock SS (Rock)

  • Project estimated costs (2010):

    • Preferred route: $132.7 million

    • Alternate route: $210.8 million


Access: Net Present Value Benefits less Project Costs (2010)

APC = Adjusted Production Costs

LLMP = Load-weighted Locational Marginal Prices

Dane County Projects Update


Background

  • Dane County has experienced major economic growth in the last 25 years.

  • Three of Wisconsin’s top 5 fastest growing municipalities are in Dane County (Verona, Cottage Grove and Sun Prairie). (Includes municipalities with a population of 5,000 or more in 2005; data source: U.S. Census Bureau.)

  • Dane County’s electricity consumption is expected to continue to increase through year 2020.

  • System-reliability models indicate that new transmission lines will be needed in Dane County by 2008 and every few years thereafter to keep pace with this growing demand.

  • ATC proposed five projects to deal with this growth


Public Outreach

  • Extensive outreach on all Dane County projects

    • Energy Initiative Study – supported a group of stakeholders and traditional interveners in review of Dane County’s transmission needs

    • Project communications, open houses

    • Ongoing consultation with regulatory agencies

    • Extensive media relations

    • Polling

    • Advertising


Dane County Transmission Projects

  • North Madison-Huiskamp – approval 7/12/07

  • Femrite-Sprecher – in service

  • Fitchburg-Verona – application complete, pending hearings

  • Paddock-Rockdale – application complete, hearings set

  • Rockdale-West Middleton – routes announced in August


North Madison-Huiskamp Project(aka “Waunakee Project”)

  • Controversy early in project

    • 39 different parties, two intervenor groups

    • More than 100 public hearing witnesses

    • Calls for ‘independent’ study

  • Excerpts from PSCW oral discussion of decision:

    • “Ebert said this agenda item represents probably the most pressing reliability challenge he has seen since becoming Chairman.”

    • “Ebert said the [PSC] was formed 100 years ago and was created precisely to conduct that independent review.”


Dane County 345 kV Project

  • Rockdale – West Middleton (Dane)

    • Resolves significant voltage and reliability issues in Madison area

    • Final routes were announced on August 1; PSCW filing in October 2007

    • Considerable public involvement effort to date. Open houses this month

    • Underground options evaluated—will not be recommended by ATC

    • In-Service: 2013


Other 345 kV Projects

  • Arrowhead – Weston

    • On schedule & budget for June 2008

  • Gardner Park - Central Wisconsin

    • WPS Weston 4 generator interconnection

    • Early in construction; in-service 2009

  • Morgan – Werner West

    • System enhancement project in NE Wisconsin

    • Early in Construction; in-service2009
