Heat network Alkmaar

In order to make better use of the opportunities for sustainable energy supply, municipalities, housing corporations and waste and energy company HVC are expanding the Alkmaar heat network.

In Alkmaar, Broek op Langedijk, Heerhugowaard and Heiloo, consumers and companies can benefit from the expansion of the heat network. In February 2016, the first phase of the expansion began: the extension of the heat network from the Alkmaar hamlet of De Nollen to the new housing estate of Vroonermeer. A.Hak laid the transport pipeline with a diameter of 12".

Various drillings

Along the way we encountered a number of obstacles that were crossed by means of drilling. For example, the Alkmaar-Den Helder railway line, which was crossed between De Nollen and Vroonermeer with a closed-front borehole. This drill made the connection between the existing part of the network and the branch line that will lead to Broek op Langedijk and Heerhugowaard.

A small lake with both nature value and recreational destination, has also been crossed by means of a borehole. In order not to disturb the breeding season of the birds, we hurried here by drilling from both sides at the same time. In this way, almost one kilometer of the route could be constructed in less than eight weeks. This is an achievement of which chief executive Ron Glas is justifiably proud.


Ten thousand homes and businesses will be connected to the Alkmaar heat network.


The CO2 emission reduction equals that of 14,000 car kilometers that are NOT driven.
