Dutch grid operators are investing billions of euros to expand the electricity network. This includes: However, grid reinforcement takes time: typically 5 to 7 years for major upgrades. 2. Congestion management In the meantime, congestion management offers a solution. Grid operators work with companies to:
Will Noord-Holland have to wait 10 years to switch to electricity?
Companies in large parts of Noord-Holland may have to wait 10 years before they can be connected to the electricity network, grid operators Tennet and Liander have warned. New companies will miss out and existing companies wanting to become more sustainable will have to wait to make the switch from gas to electricity, they said.
Will Noord Holland postpone the switch to gas?
However, so far companies major consumers of electricity have not heeded the call. Tennet is calling on companies Noord Holland to postpone the switch to gas for the time being. The greenhouses in the province have their own generation plants which the operators can call on to provide extra electricity.
