SEMINAR: Results from energy technology innovation projects - the perspective of a Swiss utility

Seminar Abstract 

EKZ is one of Switzerland's biggest energy suppliers, providing around one million people with electricity. EKZ’s distribution grid stretches over 15,000 km with an availability of 99.997 percent. As an integrated utility EKZ offers a wide range of energy services ranging from medium voltage services to solar rooftop solutions. EKZ aims to shape the energy transition towards power generation based entirely on renewable resources and the decarbonization of the sectors mobility and heating.
In the talk a summary of the hands on experiences gathered in the last five years with two MW-scale battery storage projects in different applications will be given. After a description of the Swiss electricity tariff structure and incentives, a technical description of EKZ’s solar PV activities and offering will be presented including residential batteries and self-consumption communities in multi-family homes. The talk will describe a bird eye view on flexibility and EKZ’s current flexibility usage, namely residential electric water heaters for distribution grid purposes and aggregation of industrial loads in a virtual power plant for energy market services. In the context of the full smart metering rollout new technical possibilities for demand response emerge. The talk will present the latest results from a two year pilot project using a model predictive control approach to improve the integration of solar PV into the distribution grid based on the smart metering infrastructure.
