Being in Balance: Economic Efficiency in the Dutch Power Market

In this paper, we examine economic efficiency in the Dutch power market, an important pillar for successful creation of a competitive and non-discriminatory free power market. We examine historical time series of prices and volumes on the Dutch balancing market where energy companies are obliged to offer reserve capacity in order to offset power surpluses and deficits on the grid. We argue that these balancing prices and volumes are indicators for the level of economic efficiency. We find evidence that the level of economic efficiency has increased in the Dutch power market while the level of security of supply has maintained.
