Swiss Energy Perspectives
Under the leadership of Prognos, TEP Energy will work with other renowned partners to develop the Swiss Energy Perspectives on behalf of the Swiss Federal Office of Energy.
The new Energy Perspectives 2060 is a key instrument for the Swiss government's long-term energy and climate policy. To develop them, the well-established Energy Perspectives 2050+ team consisting of Prognos, TEP Energy, and Infras has been reinforced with Meteotest, PSI, OST, and GWS. Together, we are a strong team of technical, climate, and economic experts who are developing scientifically sound and practical foundations for shaping Switzerland's energy future. The results of Energy Perspectives 2060 are used by the federal government, cantons, municipalities, regulators, grid operators, energy suppliers, and environmental organizations to update their goals and strategies.
TEP Energy simulates the energy demand of residential and non-residential buildings. It takes into account the energy efficiency of numerous electricity applications such as lighting, information and communication (ICT) including data centers, commercial refrigeration, large medical equipment, and ventilation, as well as the thermal demand for cooling and heating. The fossil fuels still in use today are to be gradually replaced by renewable energy sources and suitable technologies for heat pumps or thermal networks.
Using the building stock model (BSM) employed for this purpose, we also model gray emissions (“emissions from production” according to SIA terminology or “embodied emissions”) and material flows, thereby creating a link to demand in the industrial model. In terms of heat supply, we use the Spatial Energy Analysis Toolbox (REAT) to examine the supply-side potential of renewable energies from water, geothermal energy, and infrastructure facilities such as wastewater treatment plants and waste incineration plants. On the other hand, we use the REAT to determine the potential of thermal networks as a function of economic efficiency. In this context, we are working with the Institute for Solar Technology (SPF) at OST to investigate the role of thermal storage in load balancing and seasonal shifting.
