Location: VBG
Operator: Voralberger Illwerke AG
Configuration: 3 X 150 MW PPT
Operation: 2009
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.

Operator: Kelag
Configuration: 1 X 50 MW Pelton
Operation: 1991
T/G supplier: Sulzer Escher Wyss, Alstom
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.

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.

Quick facts: In Aug 2010, Verbund and partners KELAG and Energie AG broke ground on the Reisseck-II PSP in the Molltal Valley. The new plant links the hydraulic systems of the Reisseck-Kreuzeck and Malta projects and utilizes existing reservoirs. A 47m high by 58m long by 25m wide rock cavern for the electromechanical works was excavated at elevation 1,585m and completed in Dec 2011. Water from the upper basin flows to the powerhouse via a 5km headrace tunnel and an 800m pressure shaft. From the powerhouse cavern, a 203m tunnel runs to the lower basin. Mechanical assembly works completed in mid-2013 and wet testing began in February 2015. CKD Blansko Holding supplied the two butterfly valves. The estimated investment was €385mn of which the EIB supplied €150 of debt financing.

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.
