GWP3 - Scalability and Replication

Main Deliverables

  • Definition of a common methodology for scaling-up and replication
  • Scaling-up rules for each demonstrator
  • Summary report from Demo 1 to 6 studies: scaling-up and replication of results
  • Summary report on replication potential in Benelux
  • Summary report from EU-wide impact assessment of the replication studies




Each of the six demonstrators addresses critical features of smart grids application within EU27: it uses real-life testing of technologies and network management options which are carried out under different technical, regulatory, environmental and social conditions as encountered in each of the demonstrator’s location.  This set of specific local conditions is called the demonstration “boundary conditions”.

Using the results from the experiments to measure their impacts at EU level requires rules to be applied which will assess that:

  • Solutions can be scaled up within the demonstration region where the same boundary conditions prevails: this means, for instance, that if the results have been obtained with 1000 customers connected to the new network solution, it is possible to infer the  performance of the system for a total  of one  million clients served in the same area by the same DSO, provided that a scaling factor  is used both in terms of performance and costs of the validated demonstrations
  • the replication of the scaled up results in other regions of Europe is possible, since the boundary conditions are sufficiently close to those of the demonstrator location, meaning comprised within a given spread around the referenced conditions which ensures the general validity of replication (this range of boundary conditions is called the “domain of validity” of the demonstrator’s results)


GWP3 Definitions


The proposed approach to keep scaling up and replication costs at minimal levels assumes that a specific scaling-up and replication method is designed and used for each of the six demonstrators.

The General Work Package GWP2:

  • Identifies the barriers to be overcome in order to ensure the implementation of the smart grids solutions as demonstrated in the project
  • Defines the Key Performance Indicators (KPIs) to be used to monitor each demonstrator performance (Demonstrator KPIs)
  • Sets up the methods for the  measurement of such KPIs

GWP3 will leverage the outputs of GWP2:

  • It aims first at identifying the rules and limits for the scaling up of the results of each demonstrator within the same network where the demonstrator has worked (i.e. under the same boundary conditions). Scaling up studies answer the question: can we expect the same KPI values when the successfully demonstrated solution is implemented throughout the whole network where it can be implemented? If no, what are the corrective factors for each of the measured KPIs which must be implemented to take care of scaling up barriers? When does scaling up rules stop working, for similar boundary conditions?
  • Next, GWP3 provides then:
    • the rules for the successful replication of the scaled up results in other regions of the remaining European Member States which have not supported the demonstrations  (i.e. within a certain domain of validity of the boundary conditions)
    • The specific boundary conditions which, when not met, prevent from replication (i.e. the value of the boundary conditions which lie partly or totally outside of the validity domain)

The General Work package GWP3 will work as follows:

  • Identify the local barriers encountered in the six regions which must be removed in order to use the demonstrator results
  • Assess the local impacts of each demonstrator taking into consideration the technical and economical results (quantified by the KPIs), as well as regulatory and stakeholder acceptance issues, based on the results obtained in the six regions;
  • Infer the rules for scaling-up of the results at regional and national level in the Member States having supported the demonstrations, provided that similar validity domains are kept at regional and national level (network configuration, geography, regulatory and customers environments);
  • Infer the replication rules of the scaled up demonstrator results to be used within the validity domains of the covered boundary conditions
  • Infer the remaining issues which must still be dealt with after scaling up and replication have occurred throughout EU 27, leading to new demonstrations that are needed to better address some of the EU27 issues as listed in the SET plan (other smart grids technology mixes and boundary conditions in European countries outside the range of validity of the results of the six demonstrators)

Main objectives

  • To assess the local impacts of each demonstration quantified by the KPIs and supported by the demonstrations carried out in the six regions
  • To model customer acceptance and market potentials of the generation/ retail business models in the relevant demonstrations
  • To infer  scaling up and replication rules  for the six demonstrations
  • To cross compare results in order to make replication robust at EU 27 level. 
  • To identify barriers to scaling up of the obtained results and operational solutions to remove them
  • To conclude on scaling up rules in support of the replication of the demonstration results at EU 27 level
