The energy transition in Europe requires a profound transformation of its energy infrastructure. According to the European Commission report titled “Investment needs of European energy infrastructure to enable a decarbonized economy”, the region will need to invest over €1.3 trillion between 2024 and 2040 to ensure a decarbonized energy system.

48% of this amount must be allocated to the modernisation and expansion of the electricity grid, representing an investment of €730 billion in transmission and distribution. The report warns that without adequate infrastructure, the transition to renewable energy and large-scale electrification of the economy will face significant limitations.

The Electricity Grid: The Central Pillar of the Energy Transition

The report highlights that investment in transmission and distribution networks is the most critical factor in achieving decarbonization. The total expenditure on electricity infrastructure is expected to exceed €472 billion for transmission and €730 billion for distribution.

The growing electricity demand due to the adoption of electric vehicles, heat pumps, and intermittent renewable generation requires a significant reinforcement of distribution networks. Current systems are not designed to handle these volumes and must be urgently expanded and modernised. Without sufficient investment, the large-scale electrification of the economy could encounter operational constraints that hinder its development.

Transmission networks must also be transformed to integrate more wind and solar generation, improve resilience to extreme weather events, and enable greater interconnection between EU countries. The stability of the energy system will largely depend on these investments, as the growth of renewable energies requires a flexible and robust infrastructure.

The report also warns about the inequality in the distribution of electricity infrastructure investment within the EU. Germany, France, and the Netherlands account for more than 53% of the total financing up to 2040, while Central and Eastern Europe has only €12 billion in planned investments. This disparity could widen if equitable financing mechanisms are not implemented to accelerate the transition across all regions.

Public and Private Financing: The Great Challenge of the Transition

The European Commission identifies access to financing as a key factor in securing these investments. The scale of the required expenditure demands a strategic combination of public and private funds to bridge the investment gap.

EU funds will play a crucial role in financing strategic projects through programmes such as the Connecting Europe Facility for Energy (CEF-E), the Innovation Fund, the Cohesion Fund, and the European Investment Bank (EIB). These tools aim to reduce financial risk and facilitate access to the capital needed for energy system modernisation.

The private sector will also be instrumental in this process. A significant portion of projects is expected to be financed through mechanisms such as green bonds, investments from energy companies, and public-private partnerships. However, regulatory unpredictability and market conditions remain significant obstacles to attracting large-scale investment.

Regulatory differences and capital costs across member states create a fragmented investment environment. In some countries, returns on energy infrastructure investment are regulated by national agencies, which may limit their attractiveness to private investors. Nevertheless, the European Commission emphasises that the combination of EU funds with private investments will be essential to prevent delays in project implementation.

Hydrogen and CO₂ Storage as Pillars of the Future Energy System

Beyond the electricity grid, the report highlights the need for robust infrastructure for hydrogen and CO₂ storage, two key technologies for the decarbonization of hard-to-electrify industrial sectors. Hydrogen infrastructure investment is projected to reach €170 billion by 2040, with over 24,000 km of new pipelines and 14,000 km of repurposed networks for its transportation.

CO₂ storage will also require significant financial effort, with investments estimated between €13.6 billion and €19.3 billion. Although still in its early stages of development, the report states that this technology will be crucial for reducing emissions in carbon-intensive industries such as steel and cement production.

The growth of hydrogen and CO₂ infrastructure will face challenges similar to those of the electricity grid, including high investment costs, regulatory uncertainty, and the need to expand cross-border cooperation for the development of large-scale projects. The European Commission recommends accelerating incentives for these technologies to establish them as viable solutions within the European energy system.

Challenges That Could Delay Energy Infrastructure Investment

The European Commission report warns that several obstacles could compromise the execution of planned investments. The shortage of critical materials such as cables and transformers is causing supply chain issues and driving up project costs. This phenomenon, combined with a lack of skilled labour in the electricity sector, could result in significant delays in infrastructure construction.

The long approval processes for permits are also affecting the pace of project development. Bureaucracy and a lack of coordination between different levels of government have caused delays in several key initiatives, putting climate targets at risk. The European Commission stresses the need to reform administrative procedures to speed up energy investments.

Inequalities in investment between EU countries represent another critical challenge. While Germany and the Netherlands are moving forward with ambitious expansion plans, Eastern and Southern Europe face financial limitations that could slow their energy transition. To prevent an even greater gap, financing policies must be implemented to ensure equal access to resources across the region.

An Urge To Investment 

The European Commission report makes it clear that modernising energy infrastructure is an urgent priority for meeting the climate targets for 2040 and 2050. Without significant investments in the electricity grid, hydrogen, and CO₂ storage, the transition to a decarbonized system will face structural limitations that could undermine its success.

Access to financing, the reduction of regulatory barriers, and a fair distribution of investments will be determining factors in achieving an efficient and sustainable energy transformation. The European Union has the opportunity to consolidate its leadership in the green transition, but it must act swiftly and decisively in the implementation of strategic projects.
