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.

Regulatory Process

1. After we gather more stakeholder input and other technical and environmental information, we will further refine the preferred and alternate routes and submit our Facilities Application to the Alberta Utilities Commission (AUC). The AUC ensures the fair and responsible delivery of our utility services. The AUC will review the Facilities Application through a process in which stakeholders can participate.

2. When the AUC deems an application is complete, a Notice of Application is issued to parties that may be directly and adversely affected by the proposed project. This notice is also typically published in local newspapers.

3. The AUC can approve, approve with conditions or deny a Facilities Application.

What progress have we made?Your continued input is important to our project and helps us identify the route with the lowest overall impact.

During the first stage of consultation we received valuable stakeholder input about the preliminary route options. We used this stakeholder input and the results from further studies and field work, including environmental evaluations, to refine the preliminary route options to preferred and alternate routes.

We want your input about the preferred and alternate routes.

updated prOjeCt sCHeduleFall / winter 2011 Notify landowners of preferred and alternate routes to

be included in the Facilities Application

Late 2011 File Facilities Application with the AUC

Spring 2013 Start construction if project is approved

prOjeCt COstThe estimated cost of this project is between $95 to $145 million, which would be approximately nine to 14 cents per month on the typical residential utility bill.

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 Langdon to Janet Transmission 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 per cent 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 per cent. The transmission system always hooks up the lowest priced generator to the grid first, so generators compete to provide Albertans with cost-effective electricity.

Project overviewThis project involves a new double circuit 240 kV steel lattice transmission line approximately 18 kilometres or 59 feet in length (depending on the final route) from the Langdon Substation to the Janet Substation.

SubstationsAll of the work proposed to take place at the Janet and Langdon substations will occur on existing AltaLink-owned property.

janet substatiOnThe Janet Substation is located in Rocky View County, east of Calgary (at the corner of 50 Avenue and Garden Road SE).

langdOn substatiOnThe Langdon Substation is located in Rocky View County, and southwest of the Hamlet of Langdon.

Structure typestubular struCtureWe may also use tubular structures for certain portions of this line where there is limited right-of-way space due to existing developments.

A typical tubular structure will have a:

• height of 36 to 48 metres (118 to 157.5 feet)

• width of 11 to 15 metres at the widest arm (36 to 49.2 feet)

• base diameter of about one to two metres (3.3 to 6.6 feet)

• distance between structures averaging 275 metres (900 feet)

• right-of-way width of 40 metres (131 feet)

Preferred and alternate routingpreferred rOuteAltaLink has identified the south route option that parallels an existing transmission line as the preferred route.

The preferred route:

• is within an existing transmission line right-of-way for approximately one third of the length

• minimizes fragmentation of the land reducing the risk of land use and agricultural impacts

• has a lower visual impact

• is estimated to be comparable in cost to the alternate route

alternate rOuteThe alternate route may be used in conjunction with the preferred route.

The alternate route:

• does not parallel any existing transmission lines

• follows existing or proposed linear features for one third of its length, including storm water conveyance canals and a railway right-of-way

• requires a new 60 metre right-of-way for its entire length

• creates new visual impacts where there are currently no transmission lines

Variant route segmentAltaLink is including for consideration a variant of the preferred route from point designation C250 east along the abandoned railway right-of-way.

This segment:

• could reduce fragmentation by re-aligning the transmission line into an existing right-of-way

• has a higher amount of residences located nearby

• is shorter in length and estimated to be a slightly lower cost route

Eliminated route and line relocationeliminated rOute (beTween C260 And The LAngdon SUbSTATion)This route was removed from consideration due to stakeholder input and land impact considerations.

The route was located within two kilometres of an existing transmission line resulting in higher visual impacts and land use constraints. The route would also require a large setback distance from Highway 560 to allow for future expansion plans.

existing line relOCatiOn (propoSed 911L/850L reLoCATion)Near point designation B280 to B285, the existing 911L/850L transmission line will be relocated approximately 30 to 60 metres to the west. The relocation will require a new right-of-way.

Landowner compensationeasement aCquisitiOn• $10,000 per quarter: early access payment to perform environmental

surveying and geotechnical work (for the preferred route only)

• $250 to $5,000 per title: entry fee payment (as per the Surface Rights Act)

• $1,500 minimum: general disturbance payment

• $2,500 (titled unit) land damages payment: ($2,500 pre-construction; post-construction paid if applicable)

AltaLink will pay fair market value per acre for the total area of the easement that crosses a landowner’s property, while the landowner retains ownership of the land.

With the exception of the $10,000 early access payment, all other one-time payments are subject to the AUC’s approval of this project.

AnnUAL STrUCTUre pAymenTS (ASpS)Currently our 2011 rates for this project are:

• $1,178 per structure per year on cultivated land

• $471 per structure per year on uncultivated land

Please note the ASP is different for a monopole structure.

Factors we take into consideration when determining ASPs include:

• the loss of use of the area enclosed by the structure once operational

• the inconvenience and additional costs associated with weed control

• additional time required to operate equipment around transmission structures

• additional seed required

• overlap of pesticide/herbicide and fertilizer used when farming around the structure

• effects on cultivation

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.

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
