The objective of FLEXICIENCY is to demonstrate that the deployment of novel services in the electricity retail markets (ranging from advanced monitoring to local energy control and flexibility services) can be accelerated thanks to an open European Market Place for standardized interactions among all the electricity stakeholders and opening up the energy market also to new players at EU level. Four major distributor system operators (DSOs) ENEL Distribuzione (Italy), Endesa Distribucion (Spain), ERDF (France) and Vattenfall Distribution (Sweden) with smart metering infrastructure in place, representing the majority of smart meters installed in Europe, are running a set of four complementary large-scale demonstrations with real customers, covering one or several new services related to advanced monitoring, local energy control and flexibility exploitation and valuation. Relevant meter data will be made available by the DSOs in a non-discriminatory way close to real time, in order to enable the emergence of new energy services. Advanced interoperable platforms for making available metering data to all the interested players, either new or existing ones, will be enhanced and run in the project building on open standards. The project is assessing economic models of these new services. Based on the five demonstrations, the dissemination activities will support the preparation of the market place exploitation strategies, as well as the promotion of the use cases tested during the demonstration activities.
