The Linnamäe plant is located in northern Estonia on the Jägälä
river, about 1,5 km from the Baltic Sea coast and 30 km east of
Tallinn. The original plant was designed by Finnish professor
Axel Verner Juselius in 1917 and then built during 1922–24. It
was first commissioned in 17 Apr 1924 and connected by a 33kV
line to a paper and wood-pulp board factory in Tallinn.
The original plant consisted of spillover dam, fishsteps, dam
sluice, three turbine chambers and generator house behind the
chambers. There have been three horizontal axel 350 kW Francis-
turbines.
The plant was then bombed during the Second World War in 1941.
The plant will be rebuilt by preserving the old architectural
style. An Estonian architect Raine Karp has been responsible for
joining the new technology to the old structures. The plant will
be completed in August 2002 and have an installed capacity of
1200 kW and a mean output around 6 GWh/year. Thus, Linnamäe plant
doubles Estonia’s hydropower production.
