Antwerp Dock-water Cooling Project
The current cooling system at our facilities in Polderdijkweg, Antwerp site is 16 years old and is due for replacement.
Two out of the four compressors are no longer functioning effectively and the third is running on half power. Furthermore, the cooling gas used in this system is R22, a powerful greenhouse gas that can no longer be purchased. We have considered two options for replacing the existing system:
- The first is a straight replacement of the current installation, which would reduce energy consumption by around 7% (equivalent to 61 MWh/year, 43 tC02e) and provide a sustainable, long-term solution
- The second involves the installation of a new cooling system involving the re-use of water from the nearby dock. This has the potential to save 55% energy consumption (equivalent to 462 MW/h per year, 323 tC02e). The project would also be eligible for a one-time regional government subsidy, and a one-time subsidy from the energy supplier. Based on this, we have calculated that our return on investment of around Euro 347,000 would be achieved within 7.7 years, or 6.1 years taking into account energy price increases of 5% per year
SGS approached energy contractor, GDF Suez-Fabricom-Cofely (now trading as Engie) which is prepared to sign an Energy Performance Contract, a contractual guarantee, for the calculated savings. As such, any underperformance of this solution in comparison to the expected level of savings would be refunded. While the project proposal is subject to further discussion with external partners, we expect to be able to progress with plans in 2016.
