Improving aggregator business models to speed up flexibility



The BestRES project investigates ways to improve business models of aggregators across Europe with focus on 9 target countries : the UK, Belgium, Germany, France, Austria, Spain, Portugal, Italy and Cyprus. In close cooperation with aggregators in each of those countries, improved aggregator Business Models were developed during 2017. As a key result, the following 7 improved Business Models were identified that are economically viable and do not face substantial barriers for implementation :


The project identified the following three major challenges for aggregators:

  • The acquisition of a sufficient number providers of flexibility
  • The identification and comprehension of the impact of key regulatory challenges
  • The understanding and ability to predict price and market evolutions

For investors and financial institutions, the main objectives are assessing the feasibility of new aggregator businesses and understanding the maturity of revenue streams of aggregators. In this context, 3E is focusing on various advisory services such as the following ones:

  • An analysis of the potential opportunities from grid charge modifications in Germany
  • An analysis of the evolution of support mechanisms and PPA structures in Belgium
  • The development of time-of-use price structures in Austria
  • An analysis of the probability and impact of negative prices in France up to 2020/2030
  • Load forecasting services in Portugal

As an example of the possible implementation of one of the Business Models a B2B level, BestRES project partner Next Kraftwerke recently announced a new contract with the Lake Constance Water Supply Association in Germany to implement the Business Model supplying “mid-scale” customers with time variable tariffs including grid charges optimization. For 6 water pumps (32 MW of flexibility), a variable price calculated every 15 minutes in combination with network feed optimization allow to realise significant savings (

The results of the assessment of the economics of and barriers for implementation of 13 improved aggregator Business Models in the 9 target countries will soon be available on:
