Elia buys some 500 GWh each year to offset grid losses with voltages of between 26 kV and 70 kV.
The purchases are made using a European call for tenders which is open to all suppliers (generators, traders,...). Holding an ARP contract is the only prerequisite for taking part in the selection procedure.
At the start of the year, Elia publishes a Contract Notice indicating the required volume and inviting interested suppliers to apply. The procedure to follow and the list of documents that must be provided are detailed in this Contract Notice.
Candidates are selected on the basis of the following criteria:
- economic criteria (main business activity in recent years, experience of supplying similar services, main contracts, supplied volumes, etc.);
- financial criteria (balance sheets, liquidity ratios, solvency, profitability, etc.);
- technical criteria (quality system, suitably qualified staff, knowledge of languages, etc.).
Then the call for tenders is passed to the selected candidates. Tenders are submitted in online reverse auctions organised by Elia throughout the year with a view to supplying energy. The selected candidates are in most cases notified 24 hours before an auction takes place.
