2017-10-18 ¦ COP Meeting in Malmö, Sweden

The second Community of Practice workshop, organized in the framework of the EU-funded Project ReFlex, took place from the 18th to 20th of October 2017 in Malmö in Sweden. This event brought together up to 25 participants: Swedish, German, Austrian and Swiss project partners, stakeholders and experts of the seven running demo sites participating in the ReFlex project.


The main objectives of this event were to learn from the field-testing experiments carried out in Malmö, to identify and to discuss crosscutting issues (marketplace, stakeholders, and technology) encountered in the demo regions, to present first results of ReFlex (replicability concept and simulation studies), and finally to agree on the structure, content and target groups of the ReFlex guidebook.

The first part of the event was dedicated to the demo site Hyllie, a city-district of Malmö. The participants got first insights into the objectives and key success factors of the Hyllie project, a test bed for innovative smart grid and smart energy solutions.

Some of the key questions which arised from the site visit were:

  • Which role will “local energy communities” and aggregators play in the future?
  • How will the role of the DSO evolve?
  • How will the tariff structure of storage systems change after the introduction of new regulation? Will the grid fees charged when storage systems draw power from the grid or discharge energy be abolished or reduced (to acknowledge their role in providing flexibility to the grid)?

The second part of the event was the Community of Practice. Discussion tables were organized around the following topics:

  1. Integration of renewable energy sources in multi energy grid systems from the perspective of Municipalities
  2. What are the most relevant short-term (day/night) and long-term (seasonal storage) flexibilities when coupling various sectors? 
  3. Blockchain: risks and opportunities of the peer-to-peer transaction platform in the energy sector 
  4. Microgrid: main characteristics and benefits of operating such a grid 


Technical solutions and good practices

  • The building energy manager is a functional solution but there are no viable use case yet
  • Hyllie goes beyond smart grids towards integrated energy systems. The focus is on coupling and interactions between energy systems (heating and gas networks, electrical grid).
  • Successful cooperation between E.ON and the city of Malmö

Results relevant for the Guidelines/Research questions to be followed up

  • How could we use existing devices in a “smarter” way? What interoperability issues should be addressed? Which standards should be adopted and used?
  • What are the flexibilities that will be on the market in the future? Will the need of flexibility increase or rather decrease if assumed that the free capacity of existing assets are fully exploited?
  • What type of storage for which purpose? Could seasonal storage be an option in the future to stabilize the grid when power imbalances occur?
  • Group discussions highlighted that the regulation is the main issue to address, especially when considering replication.
  • Blockchain is still in its early phases of development. There are 2 main applications in the energy sector: automated buildings and self-consumption communities
  • How blockchain and peer to peer market may transform the energy sector? How will the energy market look like in the future? Will the day ahead market become obsolete? What will be the different role (aggregators?) and responsibilities of people involved?
  • What are the preconditions for the scaling-up or replication of smart grid/smart energy projects? Which best practices identified in Malmö should be followed and implemented (choosing the right partner, avoiding competition between stakeholders)?
  • What are the difference in cultural values and planning culture between EU member states? How is people’s perception of utilities and public services?
