Overview
Goldisthal is a 1,052 MW hydroelectric power plant in Germany, operated by Vattenfall Europe Generation AG. It is one of the largest pumped-storage facilities in Europe.
Goldisthal is a hydroelectric power plant located in the Thuringian Forest region of Germany, with a capacity of 1,052 MW. Operated by Vattenfall Europe Generation AG, it is a pumped-storage facility that plays a key role in grid stability and renewable energy integration. The plant utilizes pumped-storage technology, pumping water to an upper reservoir during low demand and releasing it through turbines during peak demand. This technology provides rapid response to grid fluctuations, supporting Germany's energy transition (Energiewende) by balancing intermittent renewable sources like wind and solar. Goldisthal's environmental significance lies in its ability to store excess renewable energy and reduce reliance on fossil fuel peaker plants. Its location in a forested area requires careful environmental management, but the plant's operational flexibility contributes to lower overall CO2 emissions in the German power grid.
Environmental context
Goldisthal's pumped-storage operation helps integrate variable renewable energy, reducing the need for fossil fuel backup. The plant's location in a forested region necessitates adherence to German environmental regulations, including water management and biodiversity protection. While hydroelectric power has low direct emissions, the construction of reservoirs can impact local ecosystems. Goldisthal's design minimizes ecological disruption through controlled water cycles and fish protection measures.
Frequently asked questions
Goldisthal is located in the Thuringian Forest region of Germany, near the town of Goldisthal in the district of Sonneberg, Thuringia.
Goldisthal has a total installed capacity of 1,052 megawatts (MW), making it one of the largest pumped-storage hydroelectric plants in Europe.
The plant is owned and operated by Vattenfall Europe Generation AG, a subsidiary of the Swedish state-owned energy company Vattenfall.
Pumped-storage plants like Goldisthal pump water from a lower reservoir to an upper reservoir during low electricity demand. During peak demand, water is released back down through turbines to generate electricity, providing rapid grid balancing.
Hydroelectric plants in Germany must comply with the Federal Water Act (WHG), the Renewable Energy Sources Act (EEG), and EU Water Framework Directive. These regulations cover water usage, ecological flow, fish passage, and habitat protection.
