Annapolis, Canada
The application of new STRAFLO™ units in replacement of old horizontal or vertical Francis units is a tremendously successful
concept to over­come space limi­tations as well as minimising power plant alterations without effecting or increasing investment costs. Consequently this concept has been repeated for sev­eral power plants including Augst (Switzer­land) and Wyhlen (Germany).
The Annapolis Royal Tidal plant featuring a STRAFLO™ turbine is installed at the Annapolis basin in the arm of the Bay of Fundy, province of Nova Scotia, Canada. The STRAFLO™ turbine was installed to harness the energy from tides of maximum 15.8 m. The STRAFLO™ unit comprises a combined turbine generator aggregate without driving shaft. The concept results in a very compact design of the unit. More than 110 STRAFLO™ units were produced by VA TECH HYDRO since 1938 worldwide. Latest STRAFLO™ unit was in­stalled in the late 1990's at the Pointe du Bois G.S. in the province of Manitoba, Canada with outstanding performance results.
