2017-06-26 ¦ Visit in Salzburg, Austria

The site visit of Salzburg took place from 26 to 27 of June 2017. On the first day, the participants from the ReFlex project went to Köstendorf by electric car, a small village in the district of Salzburg, to learn from the experiments carried out in the frame of the Smart Grid community Köstendorf. The detailed discussions continued during dinner. On the second day, a workshop was held at the headquarters of Salzburg Netz GmbH, the regional multi-utility system operator for the city and the district of Salzburg. The objectives of the workshop were to present first results of the ReFlex project and get insights from experts on Smart Grid and Smart Energy projects as well as identifying topics of interests for the next Community of Practice (COP) workshop that will be held in October 2017 in Malmö. 

Smart Grid community Köstendorf

The main objective of the Smart Grid community Köstendorf is to integrate distributed renewable energy sources (PV) and electric vehicles in an efficient way in order to increase the hosting capacity of low voltage distribution networks. Findings show that Smart Grid solutions are a way to reduce costs of the energy transition and can delay the need for grid reinforcement measures. The follow-up project Leaf will investigate how and to what extent storage systems and flexible loads can provide grid as well as energy services.

Current projects: 250 roofs program, PV Mieterstrommodell & DECAS

The scope of Smart Energy and Smart Grid projects carried out by Salzburg AG the regional multi-utility company and its subsidiary Salzburg Netz is very wide. It ranges from the provision of ancillary services through distributed resources over the implementation of new programs and services to make renewables sources easily accessible to all consumers.

The 250 roofs program aims at installing 250 PV systems (coupled with battery system if requested) to strengthen the relationships between the energy supplier and end-users. Customers engaged in the program will pay a monthly fee and benefit from a comprehensive service of Salzburg AG including energy consulting, installation, commissioning and maintenance. The property rights of the PV system are transferred to the customers after 12 years. The project started in January 2017 and the first PV systems will be deployed in July. 

The “PV Mieterstrommodell” (PV for tenants) takes into account the willingness of residents living in apartment buildings to freely use the energy that is produced on their roofs. This model gives them greater control of their energy bill. Salzburg AG is currently investigating what tariff is the most appropriate and which clearing technology should be used considering the transaction costs of the energy flows (blockchain ...). 

DECAS stands for Demonstration of Coordinated Ancillary Services. The main goal of this project is to explore how to best coordinate the provision of ancillary services such as, aggregated “prosumer” response control reserve, individual voltage control and reactive power management concepts over traditional boundaries from high voltage, medium voltage to low voltage. Such as ReFlex, the DECAS project is funded by ERA-Net Smart Grids Plus initiative. 

Specific requests to the second COP workshop in Malmö

The results obtained so far show that Smart Grid solutions are mature, cost efficient and contribute to the integration of renewable sources. However, Salzburg has an ambitious environmental agenda and wants to become carbon neutral and self-sufficient by 2050. Thus, Salzburg AG and Salzburg Netz will have to develop new solutions and strategies to support this transition. In view of the challenges ahead, the following topics are of particular interest to the experts of Salzburg: 

  1. What are the services that can be provided by domestic storage systems and which products are available on the market? (e.g. IT platform “SchwarmDirigent” developed by LichtBlick that  connects distributed energy sources like combined heat and power plants, electric cars, heat pumps, solar power and storage to the energy market)
  2. What are the most relevant short-term (day/night) and long-term (seasonal storage) flexibilities when coupling various sectors such as energy, transport and building? 
  3. Blockchain: risks and opportunities of the peer-to-peer transaction platform in the energy sector?

These 3 questions, among others, will be explored during the 2nd Community of Practice (COP) workshop in Malmö (18-20 October 2017). The event will provide a great opportunity for knowledge sharing and discussion around best practices that will further contribute to the creation of the ReFlex guidebook. We are looking forward to meeting you in Sweden!
