Pumpspeicherkraftwerk Jochberg was in Jachenau planned in the Bavarian Alps pumped storage plant . To stabilize the power grid, it should store the power peaks from renewable energy sources such as wind or solar energy for a short time and feed them back to the grid when there is increased demand. The Walchensee was to serve as the lower basin, and the upper basin was planned in a hollow east of the Jocheralm below the Jochberg .
On September 6, 2014, it became known that the Bavarian State Government would not pursue the project for economic reasons. According to a joint declaration between the Austrian Vice Chancellor Reinhold Mitterlehner and the Bavarian Minister of Economic Affairs Ilse Aigner , Austrian pumped storage capacities, such as in Kaprun , are to be used instead.
On September 30, 2014, Minister of Economic Affairs Ilse Aigner presented the potential study for pumped storage plants in Bavaria. The Jochberg project was named twice among the top 16 options - with the Walchensee and Kochelsee sub-basins . At the same time, the report of the Bavarian Ministry of Economic Affairs on the profitability of pumped storage power plants was published, which came to the conclusion that under the current market conditions "no investments in PSP are to be expected". On the other hand, it is emphasized that “Pumped storage power plants will remain the cheapest large-scale storage option for the foreseeable future. It is therefore important for this technology to maintain a place in the market, even under today's less favorable energy industry framework conditions (low price margins and revenues for control reserve) ”.
General
The construction time was planned from 2018 to 2023, the construction costs were stated at € 600 million. The operator was the Bavarian Energy Alliance , an amalgamation of 32 companies, mostly Bavarian municipal municipal utilities. At the end of September 2013, the Bavarian Energy Alliance announced a planning freeze for the project due to difficult land negotiations and pending a clear statement from the state government.
Planned technical equipment
The chosen location allows a great fall height (577 m) with a short distance between the two basins. The power plant with three Francis-type pump turbines with a total output of 700 MW was to be built in an underground cavern . With a flow rate of 139 m³ / s, the turbines could have worked for six hours at full load. The storage capacity of the upper basin would have been sufficient for a work capacity of 4200 M Wh . The planned upper basin would have had a storage area of approx. 22 ha and a storage capacity of 3 million m³ of water. The dam would have been up to 30 m high and was intended as a fill dam to be greened. The water level of the Walchensee would have fluctuated by about 18 cm due to the pumped storage operation. The operation of the already existing Walchensee power plant can cause water level fluctuations of up to 6 m.
criticism
In the course of 2013, the public was more likely to see the opponents of the project. Nature and homeland protection as well as doubts about the usefulness of a pumped storage plant were the predominant counter-arguments presented. It was also feared that the warm surface water and cold deep water could mix, making the Walchensee too cold for swimming in summer. Ilse Aigner , the Bavarian State Minister for Economic Affairs and Media, Energy and Technology, on the other hand, initially said that the energy transition would not succeed without pumped storage power plants, and that she could fundamentally imagine a pumped storage power plant on the Jochberg.
During her visit to Jachenau on November 29, 2013, Aigner declared that shaping the energy transition was a big task. Before statements about an individual project like the PSW am Jochberg, an overall concept is needed, which - like the resolutions on changes to the Renewable Energy Sources Act - will not be available before mid-2014. Without these framework conditions, no investor can decide whether a project like the one at Jochberg makes sense.
Ludwig Hartmann , leader of the Greens in the state parliament , criticized the government decision to say goodbye to the Jochberg pumped storage plant. “The more energy stored in Austria comes to Germany, the more power lines would have to be built in Bavaria.” When the project became known, the Greens did not fundamentally reject the construction.

And does not want to be put off by protests by local environmentalists. They are running storm against the plans. And they fight hard: two ornithologists from the Naturschutzbund even offered the Jochberg dairyman Hans Oswald to spread bird droppings from rare bat species on the Jocheralm. "
