The Project TransAlta continues to advance the state of readiness for our Antelope Coulee Wind project through ongoing study and stakeholder consultation. Recently, in October 2016 we hosted a Public Open House providing information on our proposed project to the general community. As part of our ongoing outreach for this project we are supplying this brochure as supplemental information to stakeholders that may not have been available to attend. We also invite you to direct any questions about our project or any wind energy questions to us directly through the contact provided on the back page of this brochure. TransAlta has a high level of confidence in the Project’s suitability at this site, having undergone extensive evaluation and assessment over the past 7 years, and we look forward to the possibility of becoming part of your community.

Antelope Coulee Quick Facts Location 35 km southwest of Swift Current Project Size Up to 200 MW (approximate) Number of Turbines Up to 65 Turbine Tower Height 80-110 meters Blade length Less than 70 meters Project Total Acres 17,000 (approximate) About TransAlta TransAlta is Canada’s largest wind generator and brings more than 100 years of experience working in the renewable electricity sector throughout Canada, the United States and Australia. TransAlta has over 8,700 MW of net capacity in operation which is comprised of a diverse mix of fuel types including, wind, solar, hydro, natural gas and coal. We currently own/operate over 1,500 MW of wind power and are one of Canada’s most experienced builders, owners and operators of wind energy facilities with 22 operating wind farms. TransAlta was the first large-scale utility company to invest in Canadian wind energy, including the first wind projects built in Canada.

Antelope Coulee Wind Project Update

January 2017

The Antelope Coulee Wind project is located on privately owned lands in the Rural Municipality of

Webb and near an area known as Antelope Coulee. Much of the land is used for agriculture and will continue to be used for this purpose throughout the life of the project. The site is approximately 35 km southwest of Swift Current in Townships 13 and 14, Ranges 16 and 17, W3M. Below is a map outlining the project study area (highlighted in yellow).

Schedule and Timing

Schedule and Timing TransAlta intends to participate in the upcoming SaskPower Request for Proposals (RFP) which is expected to be issued in early 2017. Should TransAlta be successful in the RFP process,

construction of the Antelope Coulee Wind project could begin in 2018 with a proposed operation date of December 2019.

Sound and Visual Impacts We have designed the wind farm to meet acceptable acoustic impacts over a full range of wind speeds using industry established standards, and following provincial guidelines. Acceptable sound levels are usually measured in decibels (dB) that are A- weighted, meaning that it approximates human hearing. The dB level of a typical wind turbine outside of a residence is similar to the dB level in a quiet bedroom. Visual impact is an important consideration in wind farm design. We utilize visual modeling software to assist us in creating a layout that minimizes impact on view-scapes wherever possible. Turbines are painted an off-white colour, which is found to be the least intrusive under the widest variety of light conditions.

Environmental Factors We have engaged in an extensive amount of studies on the proposed site for several years and feel it is well suited for wind energy development. Our design criteria applies industry best practices together in combination with appropriate regulation and guidance provided by regulators. Environmental assessments and studies include a variety of wildlife surveys and habitat assessments from 2009 to 2011 and again in 2014-2016 with an emphasis on birds and bats. We focused on the identification of sensitive wildlife habitat or features which may require setbacks outlined in the Saskatchewan Activity Restriction Guidelines for Sensitive Species designated by the Saskatchewan Ministry of Environment. In addition, surveys for listed rare plants were completed by a qualified vegetation specialist in areas of suitable habitat.

Archaeology Research Archaeology studies, completed in 2009 and updated in 2016 have provided valuable insight into land uses by early settlers in the area. The project will avoid the impact of any archaeological artifacts and will be safeguarded throughout the life of the project.
