Super grids that would cover whole continents are currently under serious discussion. Important rationale for building super grids would be to decrease the variability of wind power production in order to ease the integration of large scale wind power in power systems. However, there is a trade off between building new transmission lines to extend power systems and to face the costs of higher wind power variability within more local systems. In this analysis, long-term wind data was coupled with a wind power and transmission extension model to estimate the reduction in variability that continental scale power systems would bring. It is estimated that wind power production in a super grid across North America would be between 5-65 % of installed capacity for most of the time. In a more regional system similar variation is between 0-85 %. Results also include estimates on the ramping rates of wind power.
