Cooling Water
If the temperature of the cooling water used by power plants is too high during a period of warm weather and/or if the supply of cooling water is insufficient, power plants may have to limit their production of electricity because they no longer meet the relevant standards and regulations laid down by the Department of Public Works and Water Management. In such situations, TenneT’s role is to monitor the situation and issue signals to the (market) parties involved in case of (impending) shortages on the electricity market.
