With the “Clean Energy for all Europeans” package (in the following “Clean Energy Package”), the European Union (EU) introduced new provisions on the energy market design and frameworks for new energy initiatives. Specifically, the recasts of the renewable energy directive (REDII) and the electricity market directive (EMDII) provide basic definitions and requirements for the activities of individual and collective self-consumption as well as for two types of energy communities. Specifically, “renewable energy communities” (defined in the REDII) and “citizen energy communities” (defined in the EMDII), allow citizens to collectively organise their participation in the energy system.
The idea of Sunshare is to implement the concept of Renewable Energy Community for a subset of 20 residential customers: from the collection of metering information (consumption and production) to the issuing of the invoice for the participants.
Each participant to the Energy Community will receive a share of the locally produced energy (PV in this case).
As it is expected that the local production will not be sufficient to cover the need of all participants for every quarter, a “classical” energy supplier is needed to cover the balance consumption.
Hypotheses to be tested
1 | Information Flow
Test the robustness of the information flow between DSO and Sunshafre using the IO.E platform
2 | Optimisation of Metering Split
Identify the best way to split the local production between Sunshare participants. To that end 4 repartition keys will be used:
- Uniform Static: participants receive x% of the local production for every quarter;
- Proportional Static: The % participant will receive is based on his share on the total consumption for a specific month;
- Proportional Dynamic : same as the previous key but here the share in the consumption is computed for every 15 minutes;
- Dynamic optimized: use of an optimization algorithm developed by haulogy to maximise the use of local production for every 15 minutes;
3 | Management of Residual Profile
Identification of how should react (product type, pricing policy) an energy retailer to a highly variable profile of its customer.
4 | Impact on participant invoice
Assess the impact of the use of local production on the participant invoice. To that end, several network cost reductions will be tested.
haulogy is a software publisher for DSO’s and energy retailers active in the power and gas markets. The company is present in Belgium, France and in the Netherlands. haulogy has recently developed a portfolio of solutions to support Energy Communities: from metering collection and split to the issuing of partcipant invoice.
