Current power system operation is running a supply on demand system that is expected to be absolutely reliable. This has led to a power system based on highly controllable supply to match a largely uncontrolled demand. On the other hand, the main characteristic of renewable energy (solar and wind) is that the output varies accordingly to the available resource. Therefore, wind and solar energy cannot be scheduled like conventional power plants. This is commonly perceived as a challenge at high shares, since accommodating the renewable energy output can cause problems with the conventional system balancing methodologies. A way of reducing the net variability of renewable production is by the presence of balancing effect. Particularly, differential weather and climate conditions over certain areas may result in local or spatial balancing effects between different renewable energy resources. If the power system is large enough, the variability of the solar and wind energy generation can eventually be balanced, at least partially, and, therefore, the total output may be smoother than the output of individual renewable power plants. We present here an analysis of the spatial and temporal balancing between the solar and wind energy resources in the North Atlantic region based on the analysis of the Numerical Weather Prediction solar radiation and wind speed estimates. Results are promising, but a great effort regarding the development of interconnections of transmission lines across Europe are necessary to benefit from these balancing effects
