The Annapolis Tidal Generating Station, located at Annapolis Royal, Nova Scotia, is the first plant in North America to generate electricity by Tidal action. The facility, rated at 19. 1 MVA, is the largest tidal generating unit in the world. The facility is a single unit pilot plant built to evaluate the operational characteristics of the low head STRAFLO turbine and to prove the usage of such turbines for tidal power developments in the Bay of Fundy and low head river developments. The Annapolis plant began commercial operation in August, 1984. The tides in the Annapolis basin have a range extended from approximately 8. 7 M to approximately 4. 4 M, the average range being approximately 6. 4 M.
