Both regular maintenance as well as grid expansion are important to having a reliable transmission network. Careful planning is necessary for this. Does the grid still fit with the amount of electricity that has to be transported through it? What possibilities does transpower have for grid optimisation? In what sections are renewals needed for the technical components, and much more. The extensive approval processes for the construction of new lines are also conscientiously accompanied by our grid planning. Currently, around 500 kilometres of new maximum voltage lines are in the planning stage at transpower.
