Pumped-Storage Hydroelectric Plants in Austria

Feldsee
Location: KAE
Operator: KELAG-Karntner Elektrizitats-AG
Configuration: 2 X 70 MW FPT
Operation: 2009-2011
T/G supplier: VA TECH
Quick facts: This is the latest component of Kraftwerksgruppe Fragant and takes advantage of a 524m drop from Speicher Feldsee to Wurten. A new 110kV line runs to the Innerfragant substation. A second machine is being built for service in 2011.

Innerfragant
Location: KAE
Operator: KELAG-Karntner Elektrizitats-AG
Configuration: 4 X 27 MW FPT
Operation: 1969-1981
T/G supplier: Voith
Quick facts: Kraftwerksgruppe Fragant consists of a system of four storage power stations and three smaller run-of-river power stations built between 1964 and 1985. The Innerfragant powerhouse, located at 1,200m above sea level, is the hydraulic center of the entire power station group.

Kops-II
Location: VBG
Operator: Voralberger Illwerke AG
Configuration: 3 X 150 MW PPT
Operation: 2008
T/G supplier: VA TECH
EPC: VA TECH, Swietelsky, Jager Bau, Torno, Beton- und Monierbau, Alpine Mayreder, Zublin, Voith Siemens Hydro
Quick facts: Construction on Kops II started in Mar 2003 and the first set went into trial operation in Sep 2008. Little visible construction was required as the powerhouse is 150m inside a mountain and Kops Lake and  the existing compensation pool for the Rifa scheme was utilized as the reservoirs. 6.6km of tunnels were required giving a head of about 700m. ABB built the 220kV switchyard. The total investment was around 360mn.

Koralpe
Location: KAE
Operator: Kelag
Configuration: 1 X 50 MW Pelton
Operation: 1991
T/G supplier: Sulzer Escher Wyss
EPC: Rudis
Quick facts: This plant has an 85m dam.
In 2011, the plant was converted to pump storage operation. A 35m deep shaft was dug next to the powerhouse and a new pump installed. along wih a connection to the existing penstock. The project cost €23mn.

Limberg-II
Location: SBG
Operator: Verbund AG
Configuration: 2 X 240 MW FPT
Operation: 2011
T/G supplier: Voith, VA TECH
EPC: Poyry, ILF, G Hinteregger & Söhne, Porr Tunnelbau, Östu-Stettin Hoch- und Tiefbau, Swietelsky Bau Tunnelbau
Quick facts: After five and a half years of construction, Limberg-II went online on 7 Sep 2011. The project doubles the capacity of the Kapruin PSP complex and can cover approximately 10% of Austria's peak. This was Europe's largest power plant construction site. The PSP utilizes the two existing reservoirs Wasserfallboden and Mooserbodenwith a mean level difference of 365m. The connection of the two reservoirs is via a 5.4km power conduit having diameters from 4.8-6.8m, allowing for a max flow of 144 m³. The cavern with the T/G sets is 62m long, 25m wide, and 43m high. A second cavern houses the transmformers. It is equally long, 15m wide, and 16m high .Only the powerhouse entrance gate of the cavern is visible from the outside. The total investment was around €405mn.

Location: VBG
Operator: Illwerke/VKW-Gruppe
Configuration: 1 X 276 MW FPT
Operation: 1975
T/G supplier: Voith, Voest, Elin
Quick facts: This was the largest pumped-storage set in Europe when completed. The plant utilizes about 350m of head at Latschau-Rodund. The motor-generator is water-cooled in the stator and the rotor windings. Rodund I has four 50-MW conventional sets.
