The driving force behind the project is ELECTRABEL, the Belgian electricity production and distribution company.
During the execution of the project and especially after the obtained test results of the prototype One, it became clear by the partners that further completion of the contractual work programme had no techno economic justification.
The project therefore concludes with only 70% usage of the foreseen budget.
- A storage simulation tool has been developed that enables quarter-hourly daily curves to be processed while taking into account the problems of a number of customers (synchronous curve). This tool also makes it possible to monitor loading/unloading strategies. The display of results in graphic form is also an undeniable asset.

- To identify customers for which storage offers the most possibilities (micro and macro approach), two selection criteria were studied. The probabilistic criterion yielded the best result. Moreover, this probabilistic approach has demonstrated that high daily consumption does not necessarily generate high storage efficiency.
- The tariff signals emitted by the three-rate time-of-day tariff have proved to be an incentive for the development of products such as electricity storage with a view to demand-side management in a regulated market. This experimental tariff applied and the load management and storage concept have shown that it is possible to reduce strongly the customer available gridpower as well as the power demand at critical hours during winter. This equipment and its use have been tested within a DSM scope. Independently from the thermal insulation level, electrical loads like storage devices (heaters, hot water...) remain essential elements in load management and still present future possibilities.
