Oldman 2 Wind Farm Interconnection

Why are you receiving this newsletter?You are receiving this newsletter because you are a resident, occupant

or landowner located near the proposed Oldman 2 Wind Farm Interconnection project in the Pincher Creek area and we want your input.

What does this project involve?AltaLink is proposing to build approximately 50 metres of new

transmission line. The purpose of the new transmission line is to connect the proposed Windy Point Substation, owned and

constructed by Oldman 2 Wind Farm Ltd., to the existing transmission system.

We want to provide you with:

• Project details

• A project schedule

• A map of the project area

• Information about how you can provide input

Who is AltaLink?

AltaLink owns the transmission facilities in the area and is consulting with you about this project. We are aregulated utility that owns and operates approximately 11,800 kilometres of transmission lines and 270 substations. We provide electric service to more than 85 per cent of Albertans and own the majority of the transmission system in central and southern Alberta.

PROPOSED INTERCONNECTIONSITE 645AL

Electricity. When you need it.

What are the project details?New 138 kV Transmission Line

AltaLink is proposing to build approximately 50 metres of new 138 kilovolt (kV) single circuit transmission line. The line will be called 645AL and will connect the proposed Windy Point 126S Substation to AltaLink’s existing 138 kV transmission line, called 893AL. The existing transmission line is located within the road allowance of Highway 785 and will be renamed 645L when AltaLink’s New Fidler Substation and Transmisison interconnection project is complete. For more information about the New Fidler Substation and Transmission project, please visit: www.albertaetlectricityfuture.ca/satr.

The proposed 645AL line will be built with single pole structures and an H-Frame structure, approximately 15 to 20 metres (49 to 66 feet) tall and 4 metres (13 feet) wide at its cross arms. The transmission line will be located on private property and a 20 metre (66 feet) right-of-way (a physical strip of land required for a transmission line) will be required. AltaLink will consult with landowners about the proposed location of structures. Please refer to the enclosed maps for further details of the project area.

Oldman 2 Wind Farm Ltd. is proposing to build a a new substation, called the Windy Point 126S Substation. The substation site will be located on private, cultivated land at SE-27-7-29-W4M. For more information about the proposed Windy Point 126S Substation, please contact:

Steven Xuereb, Project Mananger for the proposed Windy Point 126S Substation. Phone: 1-905-278-7677 ext. 4102. Email at: sxuereb@mainstreamrp.com

The new 645AL transmission line will connect to the 138 kV line pictured above.

The proposed Windy Point Substation and interconnection location.

Why is this project needed?The Alberta Electric System Operator (AESO), the independent, not-for-profit entity responsible for the safe, reliable and economic planning and operation of the Alberta Interconnected Electric System, has identified the need to reinforce the transmission system in southern Alberta. Alberta’s electrical grid needs more capacity to make room for power generated from new wind farm projects proposed throughout southern Alberta and new transmission lines are required to support this growth.

The AESO has directed AltaLink to coordinate with Oldman 2 Wind Farm Ltd. to supply a connection from the proposed Windy Point 126S Substation to the existing 138 kV transmission system. AltaLink will apply to the Alberta Utilities Commission (AUC) to build this connection. The AUC is a quasi-judicial agency that ensure the fair and responsible delivery of our utility services.

What is the project schedule?

May/June 2010 Notify and consult with stakeholders

August 2010 File application with the Alberta Utilities Commission (AUC)

Q1 2011 Begin project construction if approval is granted by the AUC

March 2011 Complete project construction

Electricity. When you need it.

What happens during construction? Depending on where you are in relation to the project you may see or hear: • Construction crews• Installation of transmission structures• Stringing of wires on new transmission structures• Leveling and grading for the substation site• Construction of Oldman 2 Wind Farm Ltd.’s Windy Point 126S Substation

Throughout the construction process AltaLink and its contractors will follow all applicable Alberta environment legislation and requirements and will use appropriate techniques to protect water quality, soil, vegetation and wildlife habitat. Gaining access and carrying out activities on private property is done in consultation with the landowner. Any noise associated with the construction and/or operation of the new facilities will comply with the AUC Noise Control Rule 12 and any other relevant provincial and municipal noise regulations and standards.

What about Electric and Magnetic Fields (EMF)?AltaLink recognizes that some people are concerned about EMF and we treat those concerns very seriously. AltaLink has experts who are available on request to measure the EMF or noise levels around your home, and ensure that all ungrounded metallic objects such as metal buildings and fences near the transmission line are properly grounded if necessary.

Other projects in your areaAltaLink has a variety of projects in different stages of planning and development in the area. Some are related to the Southern Alberta Transmission Reinforcement, while others are part of regular work on our transmission lines and substations. You may receive further information about these projects if you are a landowner or resident in the area. Please contact us if you have questions about these or any other AltaLink projects.

• New Fidler Substation and Transmission Line• Castle Rock Ridge Wind Farm Connection

• New Russell Substation

How can you provide input?Your input is important to us and we will work with you to understand and address any questions or concerns you may have. AltaLink representatives will contact landowners, residents and occupants located near the proposed transmission line interconnection. You can provide your feedback by:

Contacting us directly Phone: 1-877-267-1453 E-mail: siting.consultation@altalink.ca.

We consider landowner comments in our project evaluations and summarize the input received from landowers in our Facility Application (FA). The FA describes our plans to meet technical requirements set by the AESO and provides information on routing, environment, costs, project components and schedules, and our participant involvement program. We will submit the FA to the AUC for its approval.

The AUC is the independent, quasi-judicial agency that ensures the fair and responsible delivery of our utility services. We have enclosed a copy of the AUC brochure Public Involvement in Needs or Facilities Applications, which describes how you can be involved in the AUC process.
