This tender concerns Vattenfall`s project to realize a Heat Pump Station that will extract waste heat from a datacenter, increase the temperature of the waste heat with a Heat Pump System and inject the produced heat in the existing district heating grid of Westpoort Warmte. The scope of Lot 1 Heat pump is the development, realization and maintenance of a Heat Pump Installation. It concerns an industrial heat pump solution that should be able to heat up district heating water of 55-65°C (condenser inlet) to 95-120°C (condenser outlet, 120°C must be reached at times!), utilizing a 35-25°C waste heat source (evaporator in- and outlet), with a total heat output of 25 MWth.

The cancelled procedure may be relaunched over time.
