Abstract

Around 60% of Switzerland’s power production is provided by hydropower. Despite its numerous advantages, the high fluctuations in turbined discharges cause hydropeaking at downstream rivers. Due to the environmental impacts of hydropeaking on fauna and flora, the Swiss Federal Act on the Protection of Waters requires dam operators to put in place remediation measures for hydropeaking effects before the end of 2030. At the same time, the Energy Strategy 2050 and the decision on the progressive withdrawal from nuclear energy production leads to the need of increasing energy shares from other sources of energy, among which, hydropower. In this context, the aim of this project is to come up with solutions that would allow for hydropeaking mitigation without hindering hydropower production.

Energy transition

An energy transition (or energy system transformation) is a significant structural change in an energy system regarding supply and consumption. Currently, a transition to sustainable energy (mostly renewable energy) is underway to limit climate change. It is also called renewable energy transition. The current transition is driven by a recognition that global greenhouse-gas emissions must be drastically reduced. This process involves phasing-down fossil fuels and re-developing whole systems to operate on low carbon electricity.

Hydroelectricity

Hydroelectricity, or hydroelectric power, is electricity generated from hydropower (water power). Hydropower supplies one sixth of the world's electricity, almost 4500 TWh in 2020, which is more than all other renewable sources combined and also more than nuclear power. Hydropower can provide large amounts of low-carbon electricity on demand, making it a key element for creating secure and clean electricity supply systems.

Energy development

Energy development is the field of activities focused on obtaining sources of energy from natural resources. These activities include the production of renewable, nuclear, and fossil fuel derived sources of energy, and for the recovery and reuse of energy that would otherwise be wasted. Energy conservation and efficiency measures reduce the demand for energy development, and can have benefits to society with improvements to environmental issues.
