Stakeholder Information Update
Edmonton-Calgary 500 kV Transmission Development
September 29, 2005 Introduction Neil Millar, vice-president, Transmission - AESO
Today’s Meeting - Purpose
• Provide industry stakeholders with initial review of project status and activities • Discuss proposed update process

• • 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
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
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
Hydro Wind Project Need:

September 29, 2005 Review of Load and Generation Forecast Trevor Cline, manager, Central System Planning - AESO
Forecast Update
What’s changed since the Need application
• • • • • • 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 Update
Adjustments made to the forecasts for this update
• 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 Update
Supply-Demand Gap
16000 15000 5,400 MW of new generation required by 2015 to fill the gap 14000 13000 12000 11000 10000 9000 8000 7000 1999 2000 2001 2002 2003 2004 2005 2006 2007 2008 2009 2010 2011 2012 2013 2014 2015

Forecast Update
Need 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.
2500 2400 2300 2200 2100 2000 1900 Winter Path Capability 1800 1700 1600 1500 1400 2003 Summer Path Capability 2004 2005 Winter capability exceeded in 2009 2006 2007
Year
2008 Summer Loading Updated Winter Loading Updated 2009 2010 2011
Forecast Update
Congestion on the Edmonton to Calgary path Forecast 2009 Seasonal Path Loading Duration Curve
Interim measures & conversion of S-KEG will reduce congestion to less than 5% 2500 If no new large units go into service in the north, path congestion forecast to be 10% during the summer hours of 2009 2000 1500 1000 500 Summer SOK Winter SOK Summer Path Capability 0 0% 10% 20% 30% 40% 50% 60% 70% 80% 90% 100%
Forecast Update
No impact on project schedule
• • • 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

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
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
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
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
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

S-KEG Conversion Siting Update
• • • • Stakeholder consultations almost complete Most concerns related to existing facilities and are being addressed Ellerslie site a busy area; powerlines, substation, Anthony Henday intersection – our expansion is relatively minor on that landscape Stakeholder discussions considering a tree screen at Ellerslie substation site
S-KEG Conversion Siting Next Steps
• Summarize commitments made to address concerns expressed and suggestions made • • File EUB application near end of 2005 Decision from EUB anticipated in 2006
Genesee-Langdon Line Siting Overview
• Two route alternatives Genesee to Lochend; parallel & greenfield, both within the West Corridor • • • • Multiple alternatives Lochend to Langdon Draft Terms of Reference for EIA filed with Alberta Environment Consultation with all landowners within 800 m of all routes Other government and non-government stakeholders also consulted
Genesee-Langdon Line Siting Update
• Consultation with approximately 2500 landowners plus agencies • First round of consultation 95% complete (individual around kitchen table and phone calls) • Most common issues are: • • • • • Land devaluation EMF Compensation Access for farm machinery Visual impact
Genesee-Langdon Line Siting Next Steps
• Evaluating the mountain of input we received to date • • • Meeting with landowner groups Information sessions planned for November • • Update package for landowners in the October timeframe • Updates and any decisions made, and summary on input received will be communicated Next round of consultations to start in January ’06 Aiming to file EUB application mid-2006
