'''Egglfing-Obernberg Hydropower Plant''' ({{langx|de|Kraftwerk Egglfing-Obernberg|links=no}}) is a [[Run-of-the-river hydroelectricity|run-of-the-river]] [[Hydroelectricity|hydroelectric]] power plant on the [[Inn (river)|Inn]], where the river forms the border between [[Germany]] and [[Austria]]. The municipality of [[Egglfing am Inn|Egglfing]], [[Bavaria]] is located on the left side of the Inn and the municipality of [[Obernberg am Inn|Obernberg]], [[Upper Austria]] on the right side.
==History==
In order to supply an aluminium smelter near [[Braunau am Inn|Braunau]] with power, two hydropower plants were to be constructed on the Inn: [[Ering-Frauenstein Hydropower Plant|Ering-Frauenstein]] and Egglfing-Obernberg. Work on the Ering-Frauenstein plant began in February 1939. In January 1943 all 3 machines were operational.<ref name="vb1"/>
Work on the Egglfing-Obernberg hydropower plant began in July 1941. The first turbine went on line in October 1944, the second in January 1946. The 6th machine went on line in September 1950. Last construction works were finished in July 1951.<ref name="vb3"/>
==Dam==
The dam is a [[concrete]] [[gravity dam]]. The powerhouse with the 6 generators is on the left side of the Inn. The [[spillway]] is on the right side and has five gates, each with a length of 23 m. Upstream of the powerhouse the dam features an additional concrete wall as a protection against bombs.<ref name="vb3"/>
==Reservoir==
At full reservoir level of 325.90 m the reservoir of the dam has a length of 12.7 km. On both sides of the reservoir are embankment dams.<ref name="vb3"/> The reservoir is part of the [[Ramsar site]] ''Unterer Inn''.<ref name="eu"/>
==Power plant ==
The power plant has a [[nameplate capacity]] of 84 [[Megawatt|MW]] and contains 6 [[Kaplan turbine]]-generators. The annual generation is about 485 mio. kwh.<ref name="vb2"/> The turbines were supplied by [[Escher Wyss & Cie.|Escher-Wyss]] and the generators by [[Siemens]]. Beginning in 1983 the original turbines with 4 blades were replaced with turbines with 5 blades. The average [[hydraulic head]] is 10.5 m.<ref name="vb3"/>
