Weiher Coal Power Plant | Saarland, Germany | 655.6 MW Capacity

Weiher is a coal-fired power plant located in Saarland, Germany, with a capacity of 655.6 MW. Operated by STEAG Power Saar GmbH, the facility is currently operational and plays a role in the regional energy supply. As a coal plant, it is part of Germany's conventional power generation fleet, which is undergoing a transition towards renewable energy sources. The plant operates under the European Union's Industrial Emissions Directive (2010/75/EU), which sets stringent emission limits for large combustion plants. Best Available Techniques (BAT) conclusions for large combustion plants apply, requiring modern pollution control technologies. The 655.6 MW capacity places Weiher in the medium-to-large scale category for coal plants in Germany, where typical units range from 300 MW to over 1000 MW. Environmental considerations for coal power plants include CO2 emissions, as well as SOx and NOx pollutants. The plant's location in Saarland, a region with a history of coal mining and heavy industry, means it operates within a regulatory framework that has progressively tightened emission standards. The facility's role in the grid is to provide baseload power, though Germany's Energiewende policy aims to reduce coal's share in electricity generation.

Coal power plants like Weiher are significant sources of CO2 emissions, contributing to climate change. They also emit sulfur dioxide (SOx) and nitrogen oxides (NOx), which can affect local air quality. The plant's location in Saarland, a region with moderate population density, means emissions may impact nearby communities. Regulatory compliance with the EU Industrial Emissions Directive and German national standards requires the use of flue gas desulfurization and selective catalytic reduction to mitigate these pollutants.
