Did you know?The existing electrical transmission system in Calgary and the communities south and east of Calgary has not had any major developments or upgrades since 1985, while the population in these communities has grown substantially.

Foothills Area Transmission Development (FATD)The Alberta Electric System Operator (AESO) has identified the need to strengthen the transmission system in Calgary and the communities south and east of Calgary. The AESO is an independent, not-for-profit entity responsible for the safe, reliable and economic planning and operation of Alberta’s electric system.

The Okotoks to Janet Project is one of the projects identified in the FATD. This project will:

• ensure the transmission system will meet growing demand in developing areas and maintain a reliable supply of electricity

• ensure power from new generation plants, including gas and wind power, is connected to Alberta’s electric grid

Did you know?A reliable transmission system keeps costs low by connecting diverse sources of power generation to the grid. Transmission costs make up about 10% of the average residential utility bill. Generation costs – the cost of actually creating power – make up the largest portion of a bill, at more than 50%. The transmission system always hooks up the lowest priced generator to the grid first, so generators compete to provide Albertans with cost-effective electricity.

DEFiniTiOn

Alberta Utilities CommissionThe Alberta Utilities Commission (AUC) ensures the fair and responsible delivery of Alberta’s utility services. AltaLink submits applications for new transmission projects to the AUC and the AUC reviews them in a public process.

next steps

1. We will contact stakeholders, provide information and answer questions about the project.

2. After the consultation process is complete, we will file a Facilities Application with the Alberta Utilities Commission (AUC).

3. The AUC will review the Facilities Application through a process in which stakeholders can participate. The AUC can approve, approve with conditions or deny a Facilities Application.

Public consultationWe will work with you to ensure your questions and concerns are understood and responded to. A summary of stakeholder comments will be incorporated into the application we submit to the AUC.

One-On-One COnsULTATiOnWe will contact occupants, residents and landowners who are on or directly adjacent to the existing transmission lines to discuss the project one-on-one by telephone and/or in person.

Anticipated project scheduleFall 2011 Notify and consult with stakeholders

Early 2012 File Facilities Application with the AUC

Spring 2013 Start construction if project is approved

Fall 2014 Complete construction

Although we attempt to follow the anticipated project schedule, it is subject to change. We will

continue to provide stakeholders with updated schedule information as the project progresses.

Project overviewThe Okotoks to Janet Project includes the removal of an existing transmission line and voltage changes to existing transmission lines.

Project details – line removalApproximately 34 kilometres (21 miles) of the existing 727L transmission line will be removed between the Janet Substation in east Calgary and the Okotoks Substation located east of Okotoks.

727L transmission structure

Project details – voltage changes on existing transmission lines The look of these transmission lines will remain the same, the voltage change will only affect the amount of power the transmission lines carry.

911l transmissiOn lineThe voltage will decrease from 240 kilovolt (kV) to 138 kV from east of the Okotoks Substation to north of the Bow River (approximately 19 kilometres or 12 miles).

At that point, the 911L transmission line intersects with the 850L transmission line and is consolidated into one double circuit line, called the 850L/911L. Double circuit structures allow us to combine two separate circuits onto one structure.

DEFiniTiOn

Kilovolt (kV)A kilovolt is equal to one thousand volts and is commonly used when describing transmission and distribution lines. AltaLink’s transmission lines range from 69 kV (69,000 volts) to 500 kV (500,000 volts). Light bulbs typically range from 1.5 to 300 volts.

911L transmission structure

Project details – voltage changes on existing transmission lines850l/911l transmissiOn lineThe 850L voltage will increase from 138 kV to 240 kV beginning at the proposed ENMAX No. 65 Substation (east of 88 Street SE and north of Marquis of Lorne Trail) to the ENMAX No. 25 Substation (near the ENMAX Shepard Energy Centre). This is a distance of approximately seven kilometres (four miles).

The overhead shield wire on the 850L/911L transmission line will be replaced with a new overhead shield wire with fibre optic cables (called optical ground wire) for improved telecommunication abilities with AltaLink’s control centre.

850L/911L transmission structure

Electric and magnetic fields (EMF)ALTALinK’s pOsiTiOn On eMFAltaLink recognizes that some people are concerned about EMF and we treat those concerns very seriously.

Based on more than 30 years of research, national and international health agencies have not concluded that EMF associated with high voltage transmission lines will adversely affect your health or the health of plants and animals. They have not recommended the general public take steps to limit their everyday exposure to EMF.

AltaLink will ensure any problems caused by interference from our facilities are corrected and all applicable guidelines are met.

Where CAn yOU Find eMF? • electric utility equipment and facilities

• household electrical appliances

• building wiring

COMMOn qUesTiOns AbOUT eLeCTriCAL eFFeCTs inCLUde:

Q Will there be TV/radio interference?a There is no impact on cable TV. Other impacts can typically be mitigated.

Q Will there be wireless internet interference? a There is typically no impact.

Q Will Global Positioning Systems be affected?a There is typically no impact.

Q Will there be any affect to cardiac pacemakers?a Most have shielding, but we can provide answers to you about the

specific model.

Q What about audible noise?a AltaLink adheres to the AUC noise guidelines.

Q What about building and fence induction?a This is mitigated through grounding we install during construction.

Q What about stray voltage?a This is not caused by transmission lines; it is more typically caused by

distribution lines or local wiring.

Environmental EvaluationAn Environmental Evaluation identifies environmental features within the project area through existing data and field surveys. Additional information is gathered from consultation with provincial and federal regulators, landowners and the public.

This information is used to assist in route development. Potential effects from the project are identified, so that mitigations can be developed to minimize or eliminate these effects.

Information within the Environmental Evaluation typically includes:

• wildlife and vegetation inventories

• wetlands, watercourse and groundwater

• threatened and endangered species identification

• terrain and soil inventories
