February 2011 St. Paul Transmission Project Why are you receiving this project information package? New transmission facilities are needed in Central East Alberta (St. Paul area). ATCO Electric has direction from the Alberta Electric System Operator to assess site and route options for these upgrades. We have prepared this summary for landowners, occupants, agencies and interested parties located near the proposed power transmission facilities. This package will provide you with important project information and will outline our public consultation process. We invite any comments, questions or concerns you may have. Please refer to page six for our contact information and details. Included in This Package: Project Overview • Project Information brochure The St. Paul Transmission Project is needed to meet • Reply Form growing demand for electricity from oil sands • Open House invitation development and pipelines and to interconnect • Alberta Electric System Operator document proposed gas-fired electricity generation as well as Transmission Reinforcement in the Central wind farms. Please see the Alberta Electric System East (Cold Lake, Vegreville and Provost) Operator (AESO) document entitled Transmission Reinforcement in the Central East (Cold Lake, Area Vegreville and Provost) Area. • ATCO Electric Information Sheets • Alberta Utilities Commission brochure If approved, the project will involve upgrades to the Public Involvement in Needs or Facilities existing St. Paul substation and construction of about Applications 35 kilometres of new transmission line from the St. Paul • Maps and drawings substation to a connection point on an existing transmission line. St. Paul Transmission Project 1 Project Need and Details St. Paul Substation When upgrades to Alberta’s electrical system are The existing substation (called 707S) is located on needed, they are identified by a not-for-profit SW-17-58-09 W4M, north of the Town of St. Paul. If organization with a public interest mandate called the approved, the substation will be expanded within its Alberta Electric System Operator (AESO). current property boundary by extending the chain-link fence 26 metres (m) to the east. This will add additional The AESO has received applications to interconnect fenced area, resulting in final substation dimensions of over 500 megawatts of wind power and proposed gas- approximately 93 m by 68 m. fired electricity generation in Central East Alberta. Demand for electricity in the Cold Lake and The substation will require the addition of two 144/25 kV Wainwright areas is expected to increase. The existing 25/33.3/41.6 MVA transformers, four 144 kV line breakers, transmission system in this region is operating at a 46 m tall self-supporting steel lattice telecommunications capacity and parts of the system are subject to low tower and related electrical and communications voltages under certain conditions. equipment. Alteration to existing equipment will include the removal of all 72 kV equipment. The St. Paul Transmission Project is part of the system reinforcement needed to meet increasing demand for electricity and to interconnect new generation. The AESO has described the need for these facilities in the enclosed document: Transmission Reinforcement in the Central East (Cold Lake, Vegreville and Provost) Area. Typical Substation 2 St. Paul Transmission Project 144 kV Transmission Line Typical Double-Circuit 144 kV “Davit Arm” Structure If approved, approximately 35 kilometres of new 144 kV double-circuit transmission line (to be called 7L139 and 7L70) will be built to connect the St. Paul substation to the existing transmission line 7L70. Construction of the double-circuit transmission line will effectively divide the existing transmission line into two parts. The section of line to the west of the connection point will be renamed 7L139, while the section of line to the east of the connection point will keep the name 7L70. The new line will consist of two sets of three conductor wires plus two overhead shield wires Approximate Dimensions strung on steel pole structures. The typical structure will be a single-pole “Davit Arm” design, Height………21m about 21 m tall. The typical distance between poles Max. Width……6m will be 100 m to 180 m. Distance between structures….100-180m Non-typical structures with taller or additional poles, anchors and/or guy wires are required where the line ends or bends, at corners, and to maneuver around and over obstacles. In all cases, minimum clearance will meet or exceed the requirements of provincial safety regulations. St. Paul Transmission Project 3 Typical Right-of-Way Transmission lines are located in corridors that have been cleared of brush and other obstacles. These are called a ‘right-of-way’. Right-of-ways must have a minimum width to ensure safety and allow for construction and ongoing access for maintenance purposes. The width of the right-of-way, and the position of transmission structures within it, will depend on the type of structure that is used. The typical right-of-way that relates to this project is 18 metres and is shown below. Details may change with final design and location. 4 St. Paul Transmission Project Route and Site Selection Facilities Application Process We have identified preliminary route options for the Once the preferred transmission line route has been 144 kV transmission line. identified, ATCO Electric will submit a Facilities Application to the Alberta Utilities Commission (AUC) to obtain Preliminary options are shown on the enclosed map. approval for the construction and operation of the proposed We have selected route options that: transmission facilities. • Avoid homes and minimize impacts on For more information about how you can participate in the residences process, please refer to the enclosed AUC brochure • Follow property boundaries wherever possible to entitled Public Involvement in Needs or Facilities provide access and to avoid impacts to Applications. agriculture • Minimize impact on built-up areas, highways, agricultural, oil and gas operations and communication facilities • Minimize impacts to environmentally sensitive areas such as watercourses, wet or steep areas, wildlife habitat and other sensitive areas such as designated historical sites Other options for transmission line routes may be considered if identified through our consultation process. The preferred transmission line route will be identified after we have considered feedback and concerns.
