Abstract:
Electricity network investment is essential for the energy transition, with annual investments of tens of billions of euros required across Europe. Network companies are already investing such amounts and delivering efficient grid investments requires more than additional money. Assessing infrastructure needs is the first step in grid investment. At local, national and European Union levels, network development planning is determined by policy choices and can greatly affect the efficiency of investments. Coordinated grid planning is crucial to set the right incentives for the efficient development of the European electricity system. An EU independent system operator could assume responsibility for network planning by providing regular, independent assessment of efficient network investment needs from a holistic European perspective. Although significant capital expenditure is undoubtedly necessary, network regulation should encourage network companies to invest in the most-efficient solutions. Current regulatory approaches may favour traditional capital expenditure, leading to system inefficiencies and higher-than-necessary consumer costs. Cross-border electricity transmission infrastructure is critical to integrate renewables into the electricity system at scale and reduce costs for European consumers. But such projects are often not built or are delayed because those that decide on and pay for the infrastructure are not necessarily those that benefit from it. A European fund could smooth negotiations between parties and accelerate the physical interconnection of the European electricity system. Fairly recovering the costs of grid investments from consumers is vital to maintain public support for the energy transition. National funds could smooth out cost impacts over time, keeping electricity affordable throughout the energy transition.
