The largest heat pump in the Netherlands for Eneco

Making an existing heating system more sustainable, that's what it's all about. As a permanent advisor to Eneco, we take care of the legal aspects of realising the largest heat pump in the Netherlands. A heat pump installation, which will be linked to an existing sewage treatment plant. The beauty of the heat pump is that it efficiently uses the residual heat produced by the treatment process as sustainable heat. Heat that would otherwise be lost is now used to heat approximately 20,000 homes via Utrecht's district heating network. With a view to the future, this project lays the foundation for similar projects to generate thermal energy from wastewater.

Legal Counsel at Halsten:

“Before this project, Eneco and Halsten already had a long relationship. Hence we were involved from the letter of intent to the final investment decision. The project started – like every project – with initial discussions on the conditions under which Eneco would be allowed to realise a heat pump installation on the Water Board’s plot. After these negotiations, the tendering and contracting phase started. In a small team, we successfully supervised this phase. Our broad knowledge and experience of procurement legislation and (inter)national contract forms such as FIDIC, UAV 2012 and UAV-GC 2005 was the strong basis for providing Eneco with concrete and pragmatic advice.

In the long duration of a project like this, changing circumstances along the way cannot be avoided. It is then up to us to adjust the course to this immediately. The project was a challenge because of its scale, among other things. While a heat pump installation is in itself proven technology, a heat pump installation on this scale has never been carried out before. With no manual, it was up to the team to reinvent the wheel.”
