At the end of 2012, Forest Kerr was 75 percent complete. In the first four months of 2013, it has advanced another [x] percent. The tunneling is complete, the in-river work is complete, and completion of the powerhouse is ahead of schedule. There are no major components that are on critical path anymore and we expect the plant to be mechanically complete by the end of the year. We expect to commission the plant by mid-2014 once the Northwest Transmission Line is up and running. The project overall remains on budget and ahead of schedule.The 195 MW Forrest Kerr can power approximately 70,000 homes
8 Forrest Kerr Weir January 2013 May 2013 The weir is the structure that will control the flow of water into the power tunnel, and ensure that the majority of water continues to flow in the Iskut River at all times.In these two pictures you can see that the weir went from a foundation to being in operation in a short amount of time, thanks to everyone’s hard work on-site.During planning both THREAT and government requested Altagas to minimize the interruption of sediment transport in the Iskut by filling in behind the weir. The natural River sediment load is 60 million tonnes per year and would fill up behind the weir in one year. Sediment transport is a key component of the natural Iskut ecosystem and will be a long term monitoring requirement of Altagas to ensure the project functions as designed.
