Operations building

The Schärding-Neuhaus power plant is a run-of-river power plant on the lower Inn , which is operated by Österreichisch-Bayerischen Kraftwerke AG (ÖBK) . The dams are located in the area of ​​the communities Neuhaus am Inn ( Lower Bavaria ) and St. Florian am Inn ( Upper Austria ).

history

Construction work on the main structure and the storage space of the power plant began in 1958. For the construction of the power plant Schärding-Neuhaus was commissioned by the ÖBK the Innwerk AG responsible that the barrages Braunau-Simbach (1951-1954) and Passau-Ingling (1962-1965) built. In October 1961, the Schärding-Neuhaus barrage finally went into operation as the second ÖBK power plant with the commissioning of the first of a total of four machine sets. For the preparation of the storage space, extensive adaptation work on the shore zone was necessary , particularly in the area of ​​the communities of Suben and St. Marienkirchen near Schärding . In Suben the "Subener Bay" was created, while in St. Marienkirchen the course of several streams was diverted along the old Antiesen river bed.

technology

At this barrage of the Inn , an average head of 11.2 m is available. Up to 1,152 m³ / s of the outflowing water volume are used for the 4 turbines. The current expansion capacity of the plant is 96 MW .

Electricity is generated with four Kaplan turbines near the Austrian bank. The movable elements of the dam are located near the Bavarian bank. The switchgear is also on the Austrian side.

Like the other power plants on the lower Inn , the Schärding-Neuhaus barrage does not have a lock . Upstream, the storage space that can be used for energy generation is limited by the Egglfing-Obernberg power plant , and downstream by the Passau-Ingling power plant , the last barrage before the confluence with the Danube.

Construction costs

The total costs of building the barrage amounted to DM 139.4 million, which, adjusted for inflation, corresponds to today's EUR 317 million. The costs are as follows:

	Million	%
Land acquisition	6.6	4.7
Project planning	2.8	2.0
Construction management	3.9	2.8
Construction costs in the step area	36.7	26.3
Construction costs in the backwater	40.1	28.8
Bank fuses undercurrent	2.6	1.9
Machine equipment	23.0	16.5
Electrical equipment	14.9	10.7
