Perception of barriers for expansion of electricity grids in the European Union

Many of the scenarios for decarbonising the European energy system involve the integration of large-scale and decentralised renewable energy sources, such as wind and solar power. However, such integration requires substantial and rapid improvements to the existing transmission grids. Using a mix of qualitative and quantitative methods, we analysed the opinions and views of stakeholders concerning the main barriers and solutions to this problem. The results suggest two conclusions. The first is that primary barrier to the currently needed level of grid expansion are not technical or financial, but the lack of appropriate regulatory frameworks and public acceptance. The second is that major changes are needed in the overall regulatory process, rather than simply minor modifications or improved implementation of existing regulations.
