It has its own age, its own history and its own service life - independent of the asset it sits in. - it is intended to give customers an incentive to avoid high demand peaks and thereby relieve pressure on the grid. The model is controversial: households with EVs and heat pumps can incur high demand peaks even with low total consumption. NVE regularly adjusts the model based on experience.
