Flexible consumption is the appropriate response to the volatile production of green electricity, and flexibility would be promoted if the electricity system were at least partially bidirectional. According to TSCNET shareholder Energinet, the Danish transmission system operator (TSO), this is where the customer comes into play. For example, electricity consumers should be able to sell power from the battery in their electric car to the grid. Of course, this requires data and new market models that actively use the flexibility of consumers.
“Consumers should be at the centre of the future energy system”, explains Søren Dupont Kristensen, Senior Vice President at Energinet. Already since June 2017, the Danish TSO has been operating a datahub collecting all consumption data for private consumers. That also applies to the Estonian TSO Elering. On this account, the two TSOs have recently signed an agreement on a joint pilot project in the Estonian capital of Talinn. The aim is to develop a new technology that gives market players access to consumer consumption data in a simple and secure way, as well as to establish a cros-border data exchange system.
The two TSOs have already begun the first tests of the blockchain-based authentication and authorisation system called “Sovrin”. Fail-safe identification of consumers or electrical devices, protected handling of consumer data, and secure communication between systems and plants are all overly important in this regard. Søren Dupont Kristensen emphasises that Energinet and Elering are working on “technical specifications, to allow anyone who wants to use it to develop similar solutions”. Thus, an open source solution is intended, so that the research could also be for the benefit of other TSOs.
