  1. Stakeholder Information UpdateEdmonton-Calgary 500 kV Transmission Development September 29, 2005 Introduction Neil Millar, vice-president, Transmission - AESO

  2. Today’s Meeting - Purpose • Provide industry stakeholders with initial review of project status and activities • Discuss proposed update process

  3. Agenda (9 AM to 11 AM) • Introduction and context (Neil Millar) • Review of load and generation forecast information (Trevor Cline) • Overview of overall project status(Andy Kneubuhler and Stephen Kane) • Progress towards facility application(Mark Johns) • Review proposal for ongoing information updates and stakeholder feedback (Fred Ritter) • Wrap-up

  4. AESO Core Business Functions • Operate Canada’s first competitive wholesale electricity market • Direct the safe and reliable, real-time operation of Alberta’s interconnected electric grid • Plan the transmission system and make arrangements for upgrades and additions • Provide open and non-discriminatory access to Alberta’s transmission system • Coordinate and conduct provincial settlement – about $5 billion in annual energy transactions

  5. Transmission Facility Owner Business Functions (AltaLink and EPCOR Transmission) • Own, operate and maintain existing assets • Construct new transmission reinforcements based on direction from the AESO (after EUB approval of need application) • Detailed design and engineering • Securing specific rights-of-way • Develop Facility Applications and obtain “Permit and License” from EUB

  6. Project Need: • Generation in North • Load growth Red Deer & • southern Alberta • Over 20 years since • corridor was reinforced • Coal • Coal Coal • Gas • Gas Gas Hydro Wind

  7. Edmonton–Calgary Reinforcement • Key Elements • S-KEG Lines Conversion to 500 kV (Keephills-Genesee-Ellerslie) • New 500 kV line (Genesee to Langdon) • Benefits • Necessary to reliably serve Alberta (Red Deer & south) • Remove barriers to new generation • Significant line loss savings

  8. Progress To Date • AESO filed Need Identification document in May 2004 with EUB • EUB hearing in December 2004, closing in January 2005 • EUB Approval of Need received in April 2005

  9. Stakeholder Information UpdateEdmonton-Calgary 500 kV Transmission Development September 29, 2005 Review of Load and Generation Forecast Trevor Cline, manager, Central System Planning - AESO

  10. Load forecast increase - Alberta Internal Load expected to exceed 13,700 MW by 2015; an increase of 1,800 MW due to rapid oil sands growth TransAlta is asking the EUB to amend its 900 MW Centennial permit to allow for the construction of a smaller 450 MW plant All Clover Bar units are to be retired before 2006 Wind generation requests have increased above the forecast Proposed Bow City two-unit 1000 MW coal plant for southern Alberta continues development with public disclosure in January and open houses in March 2005 Calgary area capacitor banks approved and will be in-service by February 2006 Forecast UpdateWhat’s changed since the Need application

  11. Total wind generation to be installed by 2010 increased from 800 MW to 1500 MW On-site generation and load increased All Clover Bar units retired before 2006 New 500 MW coal plant added in southern Alberta in 2010 Completion date for third coal unit at Keephills changed from 2009 to 2011 Forecast UpdateAdjustments made to the forecasts for this update

  12. 5,400 MW of new generation required by 2015 to fill the gap Forecast UpdateSupply-Demand Gap

  13. Winter capability exceeded in 2009 Forecast UpdateNeed Timing: Need is now. The AESO will have interim measures in place to ensure reliability requirements are met between the need date and the in-service date. Summer capability exceeded in 2007

  14. Forecast UpdateCongestion on the Edmonton to Calgary path Interim measures & conversion of S-KEG will reduce congestion to less than 5% If no new large units go into service in the north, path congestion forecast to be 10% during the summer hours of 2009

  15. Capability increase in Edmonton to Calgary transmission capability is needed before the summer of 2007 therefore early conversion of the S-KEG is still required Increase in Edmonton to Calgary transmission capability is still required as soon as possible to address both reliability concerns and congestion The AESO is in the process of implementing interim measures that will bridge the gap between the need today and when the new facilities will be in place Forecast UpdateNo impact on project schedule

  16. Questions?

  17. Stakeholder Information UpdateEdmonton-Calgary 500 kV Transmission Development September 29, 2005 Overall Project Status Andy Kneubuhler, manager, 500 kV Projects - AESO Stephen Kane, senior project manager - AltaLink

  18. 500 kV Project Components South-KEG 500 kV Conversion • One 500/240 kV transformer bank at Keephills by AltaLink • Two 500/240 kV transformer banks at Ellerslie by AltaLink • Conversion of 1203L and 1209L by AltaLink • Conversion of Genesee substation by EPCOR Transmission • Conversion of three Genesee unit transformers by generation owners

  19. 500 kV Project Components Genesee to Langdon 500 kV Line • Line termination at Genesee by EPCOR Transmission • Line termination at Langdon by AltaLink • 1205L addition by AltaLink

  20. AESO Progress to September • Engineering studies to define equipment function and high-level specifications • Transformer capacity and overload requirements • Phase shifter capacity and angle range • Fault level studies • Coordinate activities between TFO’s (AltaLink & EPCOR Transmission) • Hold monthly project coordination meetings • Develop a functional specification for each project • Develop project monitoring and reporting processes

  21. Project Cost Evaluation • Budget baseline from the Need Application is in 2004 dollars • The TFO estimates accompanying the Proposal to Provide Service (PPS) and subsequent updates will be in end-of-project dollars • S-KEG completion November 2007 • Genesee to Langdon Line completion September 2009 • Developing a financial tracking method to allow comparison of costs to the budget on an ongoing basis

  22. Project Scope Refinements and Cost Estimates • Detailed engineering progression will provide updated information and improved estimate accuracy • AESO functional specification and TFO Proposal to Provide Service defines the project scope • Assessing the impact of trends in transmission materials, major equipment and construction costs on the project • Updated cost information will be shared with stakeholders before year end

  23. EUB Need Approval Amendment • Detailed engineering has led to the need to file an amendment application with the EUB • The AESO’s application will contain the details of the required change and associated cost and the benefits • The application will be filed in October and available to stakeholders at that time

  24. Amendment Application Overview • Change Keephills and Ellerslie transformers from 750 MVA three-phase units to 1200 MVA single-phase units • Transformer size was revisited as a result of additional engineering studies • The amendment will provide detail about the benefits and costs; some of the benefits include: • enhanced loss savings • improved operating flexibility and future capacity • less impact on generating plants following contingencies
