RECONSTRUCTION OF THE 120-kV LINES

Transcription

1 Note: kv is the abbreviation for kilovolt, which is equal to 1,000 volts. RECONSTRUCTION OF THE 120-kV LINES Between Vignan, Templeton and Interconnexion-Maclaren Substations INFORMATION ON SOLUTION SELECTED Spring 2017 Hydro-Québec plans to rebuild a number of lines located in the city of between Vignan, on Boulevard Gréber, and Interconnexion-Maclaren, in the Masson-Angers sector. One of the many benefits of this project is that two lines will be replaced by a single line over 4 km, greatly decreasing the number of support structures. In addition, the lines will be rebuilt in the existing right-of-way, except in three locations, and a number of the s will be installed at the same place as existing s. Finally, the project will allow Hydro-Québec to maintain and improve service quality. Hydro-Québec has selected the solution with the least impact based on the environmental, technical and economic studies carried out since 2014.

2 VIGNAN SUBSTATION TEMPLETON SUBSTATION PROJECT DESCRIPTION Following the consultation done in 2016, Hydro-Québec decided to keep the existing s for 3 km of the route, between the Erco Mondial tap and Interconnexion-Maclaren, where only the cables and fasteners will be replaced. Based on technical and economic criteria, the same decision was made for the five s between the Produits-Forestiers-Résolu and its tap line. SECTION 1 Vignan to Produits-Forestiers-Résolu Two 120-kV lines run parallel in this 4.1-km segment. Hydro-Québec will completely dismantle one of the two lines and rebuild the other, except in the stretch between the Produits-Forestiers-Résolu and its tap line, where only the conductors and fasteners will be replaced. Of the 42 s currently in place, 5 will be kept and the rest will be replaced by 10 new s. SECTION 2 From the Produits-Forestiers-Résolu tap to Templeton In this 6.4-km section, Hydro-Québec will replace the single-circuit line with a new double-circuit line between the tap, at the corner of Gouin and Laviolette streets, and Templeton, located on Montée Dalton. Towers will be rebuilt inside the right-of-way and, where possible, at their existing locations. However, part of the line must be slightly rerouted outside the existing right-of-way due to the presence of a zone subject to mass movements near the. One will have to be moved approximately 40 m from its current location. SECTION 3 From Templeton to Interconnexion-Maclaren INTERCONNEXION- MACLAREN SUBSTATION In this 13.6-km section, Hydro-Québec will replace the single-circuit line with a new double-circuit line over 10.6 km, between Templeton and the Erco Mondial tap. In the remaining 3 km, from the tap to Interconnexion-Maclaren, only conductors and fasteners will be replaced, as the existing s will be kept. Towers will mainly be rebuilt inside the right-of-way and, where possible, on their existing locations. To avoid erecting s in the median strip of Highway 50, Hydro-Québec needs to modify the angles at which the line crosses the highway, and must therefore reroute a total of 1.5 km of the line outside the existing right-of-way. 2 * kv = kilovolt, or 1,000 volts

6 RESULTS OF THE PUBLIC PARTICIPATION PROCESS A favorable reception from local communities is one of the three essential conditions for Hydro-Québec projects. When developing each new project, the company seeks to balance the impacts associated with the three pillars of sustainable development: social, environmental and economic. In spring 2016, consultations were held with the municipality, affected landowners and various community organizations. Residents had a chance to express their concerns during open-house events. Since the new line will be built in an existing right-of-way, we were able to make only a few minor adjustments to the location of certain s. PROJECT BENEFITS Rebuilding the lines and replacing the conductors will allow Hydro-Québec to maintain and improve service quality. Rebuilding the lines mainly within the existing right-of-way reduces the impact on the landscape. The new line will be supported by steel lattice s. Most will be reducedfootprint models, with four-legged s in certain locations.
