AYA

The Brussels public transport company wants an all-electric bus fleet by 2035, so its power needs will keep growing. Its energy was already 100% renewable through guarantees of origin and rooftop solar, but it wanted local green power at a price less exposed to the market. AYA developed the procurement strategy, found the producer, Aspiravi, and guided the contract as an independent advisor between buyer and producer. Since April 2023, MIVB buys 100% of the power from new wind farms in Pelt, Ruddervoorde and Wervik. The deal was closed within a few months, despite the constraints of a public tender.

As a member of RE100, Decathlon is committed to 100% renewable electricity. In Belgium, about 35% of the capacity it needs already came from solar panels on its stores, but energy kept getting more complex. AYA drew up the strategy, looked at off-site renewable options and negotiated an off-site PPA: five years of solar power from a site in Belgium, at a fixed price that does not follow the market. AYA also runs Decathlon's click strategy for its traditional supply, handles contract negotiations and invoice follow-up, and consolidates the energy data, with one Energy Manager as the permanent contact.

Shurgard runs self-storage sites in the UK, the Netherlands, France, Germany, Sweden, Belgium and Denmark. It had clear climate targets but needed a plan that worked across different energy markets with limited internal resources. AYA built an energy roadmap that ranks measures by impact and return: efficiency, gas heating replaced by heat pumps, on-site solar, batteries where the business case holds, then PPAs and guarantees of origin for the remaining grid power. AYA then moved to execution in the UK: technical specifications, competitive bidding among installers, follow-up of the works and on-site inspections before approval.

The energy crisis doubled A.S.Z.'s energy costs. The hospital already had projects running (relighting, internal monitoring, solar panels, new windows) but wanted a partner from A to Z, not a one-off audit. AYA audited its three campuses in Aalst, Geraardsbergen and Wetteren, which gave quick wins such as replacing circulation pumps as well as long-term plans. It supports the EPC obligation for non-residential buildings, studies how many PV panels the sites can take and, on that basis, the right external PPA for the whole group, all fitted into the existing energy contract.

OPZ Geel, a public psychiatric care centre with 250 residential beds and 75 beds in psychiatric care homes, has anchored sustainability in its master plan 'OPZ Geel wordt OPZ Groen'. Faced with a volatile energy market, it asked AYA for a strategy that combines on-site renewable production, PPAs and better traditional energy contracts. The AYA platform gives it a view of energy flows, the actual cost per MWh and the savings made. The next steps are electrifying heating with heat pumps, covering that demand with green electricity and possibly using the heat pumps on the flexibility market.

An intermunicipal utility that buys energy for several public partners had to secure new electricity and gas contracts for 2027–2029. It had to follow a transparent public procedure, its existing contract structure limited price competition, and it needed more room to use market opportunities without unmanaged risk. AYA supported the whole public tender: technical specifications, price formulas and market timing, all within defined risk limits.

An operator of several event and exhibition venues had an electricity contract indexed to spot prices, which made budgeting hard and put pressure on internal decisions. The goal: less price risk without giving up its sustainability commitments. AYA organised a structured tender, used scenario-based market timing and redesigned the contract to balance price and budget certainty. Supply stays fully covered by European guarantees of origin, and the organisation now has a clear decision framework shared by finance and operations.

A transport company was extending its PV and adding battery storage while its electricity contract was about to end. Prices were no longer competitive, there was no clear hedging strategy and too little time to run a tender alone. AYA managed the tender, optimised market timing with scenario modelling and restructured the contract to fit the upcoming assets, with hedging advice matched to the company's risk profile.
