2009 Scenario Reliability Assessment - NERC

Scenario Reliability Self-AssessmentsThe project, scheduled for commissioning in 2011 through 2012, will give Hydro-Québec’sgenerating fleet an additional capacity of 918 MW and an additional output of 8.5 TWh per year,distributed as follows: 821. additional output at Eastmain-1-A and Eastmain-1 powerhouses: 2.3 TWh.Romaine Complex2. output at La Sarcelle powerhouse: 0.9 TWh.3. additional output at Robert-Bourassa, La Grande-2-A and La Grande-1 generatingstations: 5.3 TWh.Hydro-Québec Production has obtained the necessary approvals to build a 1,550 MWhydroelectric complex on the Rivière Romaine, on the lower north shore of the St-LawrenceRiver. The complex will consist of four hydro generating stations with an annual output of 8.0TWh. Construction has begun in March of 2009 and is scheduled to be completed in 2020. Thefirst Romaine commissioning is planned for 2014. Project information, in English, is available atthis web address: http://www.hydroquebec.com/romaine/pdf/2009G133_la_romaine_en.pdfCapacity Transactions on PeakQuébec has a 200 MW firm purchase contract with New Brunswick until October 2011.There are two firm export contracts. One is with Ontario (145 MW) until the end of the horizonof this study. The other contract is with New England (310 MW until the end of 2011).Hydro-Québec Distribution includes, when planning its resources, a potential of 1,000 MW ofinterconnection assistance for winter months (mainly from the state of New York). Whenneeded, short term calls for tenders are launched and transmission capacity is reserved for thoseshort term purchases. Hydro-Québec Production can participate in theses calls for tenders.TransmissionIn 2009 TransÉnergie has commissioned a new 2 X 625 MW back-to-back HVdcinterconnection with IESO in the Ottawa-Gatineau Area across the Ottawa River (The OutaouaisInterconnection). This station is integrated into the 315 kV double-circuit existing line fromChénier in the Montréal Area to Vignan in the Gatineau Area. The Ontario side of the station isa 240 kV section integrating a double-circuit 240 kV line from Hawthorne substation in Ottawa.In 2010, a new 315 kV double-circuit line between Chénier and Outaouais and a fourth 735/315-kV transformer will be added to permit full use of the interconnection.82 Information regarding this project can be found at these websites:http://www.hydroquebec.com/rupert/en/index.htmlhttp://www.hydroquebec.com/eastmain1/en/batir/resume.html2009 Scenario Reliability Assessment Page 113
