Welcome Big Rock Transmission System Development Your input is important to us. Did you know? Upgrading the transmission system in the Okotoks, High River and Black Diamond areas will ensure that businesses and residences will continue to have access to safe and reliable power at the flick of a switch or the push of a button. Regulatory process We will continue to consult and communicate with stakeholders throughout the application process and with affected stakeholders during any future construction process. Public consultation Your involvement is important to us. AltaLink understands that landowners, occupants and residents have information we need to consider when evaluating potential routes. Input from affected stakeholders is very important to the process of selecting routes and sites with low overall impacts. We will work with you to ensure your questions and concerns are understood and responded to. We will include a summary of stakeholder feedback in the application we file with the Alberta Utilities Commission (AUC). Please contact us if you have any questions or would like to provide your input. 1-855-230-6115 (toll-free) [email protected] Visit us online at www.altalink.ca/projects Electricity at a glance GenerationGENERATION Generating GENERATIONGENERATIONATCO Power facilitiesGeneratingGenerating Generatingconvert facilities ATCOGENERATION Power facilitiesvariousGenerating formsconvert of TransAltaGENERATIONATCOATCOTransAlta PowerPower facilities convertconvert various GENERATIONATCO Power facilitiesvariousGeneratingenergy forms convert into of CapitalCapitalATCO TransAltaPowerTransAlta Power Power Corporation Corporation various forms of ATCOTransAlta Power variousfacilitieselectricenergy forms convertintopower.forms of of energy CapitalCapitalENMAX ENMAX PowerPowerTransAlta Energy Corporation CorporationEnergy energy into Capital PowerTransAlta Corporation variouselectricenergy forms power. into of CapitalWindENMAXENMAX WindPower turbines turbines EnergyEnergyCorporation electric power.into electric power.

Demand for power is on the rise in Alberta The majority of the transmission system in the Okotoks, High River and Black Diamond areas has not had a major development or upgrade since 1985. Since then the local populations have increased and significant advances in technology have been made, resulting in increased demand for electricity. Population growth 1985 Now Okotoks 5,000 25,000 High River 5,000 13,000 Black Diamond 1,400 2,400 Powering Albertans’ quality of life Albertans depend on electricity every day to enjoy their quality of life. Transmission reinforcements in the area will ensure present and future electricity demands can be met by linking electricity from where it’s produced to where it’s needed so Albertans can have the power they rely on every day. Did you know? The amount of energy used to power home electronics in residences across Canada more than doubled between 1990 and 2007. The majority of Canadian homes have more than one television and more than a quarter of households used at least three sets in 2007. TVs, DVD players and other electronic devices are drawing more and more power from the grid on a continual basis. Project details The Big Rock Transmission System Development involves reinforcing the transmission system in the Okotoks, High River and Black Diamond areas. The proposed Big Rock Transmission System Development includes: • building a new substation (to be called Big Rock) • modifying the existing Okotoks, Black Diamond and High River substations • rebuilding approximately 18 to 22 kilometres (11 to 14 miles) of existing transmission line • building approximately seven to 12 kilometres (four to eight miles) of new transmission line • removing approximately 11 kilometres (seven miles) of existing transmission line Big Rock Substation We have identified a preferred and alternate substation site for the proposed new Big Rock Substation and eliminated two potential sites from consideration. The Big Rock Substation will include: • three circuit breakers • one transformer • one switchgear building • one control building The substation fenced area will be approximately 80 x 90 metres (265 x 300 feet) and will need to be located on a parcel of land approximately 150 x 150 metres (500 x 500 feet). Additional land may be required for access to the substation. The substation would be a modular substation, meaning that the major components of the substation would be built ahead of time and assembled at the site. This would reduce cost and maintain the construction schedule for the project. The proposed Big Rock Substation would look similar to the substation pictured here.
