The package includes what the Commission calls a “gap filling process” where the Commission can identify and address gaps in cross-border electricity transmission that have not yet been plugged by “suitable project proposals”. This is particularly important for the Commission as, according to the body, national regulators “do not have the power to deal with cross-border infrastructure planning”.
The Commission also noted a “substantial gap” between the current state of cross-border transmission infrastructure and the pace of future developments to ensure energy security across the bloc. The Commission notes that Europe is currently on pace to have 41GW of cross-border electricity transmission capacity in place by 2030, less than half of an 88GW tarobtain put in place; this tarobtain increases to 108GW by the finish of 2040.
The Grids Package will also emphasise public participation in project planning, another area that the EU is uniquely positioned to oversee, as these grid projects will affect people across national borders. The Commission has proposed that new renewable energy projects larger than 10MW would “share benefits with the local population”, and it would work to ensure “fair cost-sharing” between groups involved in energy generation and transmission projects, but did not provide further details on these processes.
Similarly, the Commission announced plans to “provide more transparency and predictability in the way costs and benefits are assessed and shared” for these cross-border projects, but did not provide further details on how it would go about doing this beyond a general commitment to establish “EU-wide principles for a fair and predictable cross-border cost-allocation process”.
Tackling interconnection inefficiencies
The Commission acknowledged that developing a robust cross-border grid, and one that emphasises renewable energy and battery energy storage systems (BESS), is integral to ensuring Europe’s energy security following considerable criticism of its existing grid infrastructure.
The EU has already set a 15% interconnection tarobtain by 2030 for its member states, but noted this week that “several” countries are not on track to meet this tarobtain. The Commission described the potential cost of inaction, and thus reliance on imported fuels, particularly oil and gas, as “staggering”; in 2022, 98% of all oil and gas utilized by EU member states was imported from outside the bloc.
The Commission also noted that industrial electricity prices in Europe in 2024 were more than double that of China and the US – €0.199/kWh (US$0.23/kWh) compared to €0.082/kWh and €0.075/kWh, respectively -, while the average electricity price for EU consumers was as high as €0.3835/kWh in Germany. The theory is that improving transmission infrastructure within the bloc would assist reduce reliance on electricity imports from farther afield, and minimise some of the power price discrepancy between individual member states.
However, the Commission noted that upgrading Europe’s cross-border energy infrastructure would require a mammoth €1.2 trillion investment until 2040, creating clear the scale of the challenge. However, it argued that greater cross-border energy resilience would lead to long-term financial benefits for the bloc. It noted that grid investment of €5 billion would reduce system costs by €8 billion, while “enhanced market integration” could generate annual cost savings of as much as €40 billion.
Commission proposes eight ‘energy highways’
The Commission also estimates that boosting cross-border electricity trade by 50% could increase annual GDP growth in the EU by around €18 billion by the finish of the decade, and facilitating more cross-border transmission and trade is a key component of the ‘energy highways’ component of the Commission’s proposal.
The second part of the Commission’s proposal, and one that aims to expand cross-border transmission capacity in particular, takes the form of eight ‘energy highways’, in the following areas:
- The Iberian Peninsula, connecting Spain and Portugal to central Europe via the Pyrenees mountains.
- The Great Sea Interconnector, connecting Cyprus and continental Europe.
- The Harmony Link, connecting the Baltic States to one another.
- The TransBalkan Pipeline (TBP), a reverse gas flow to improve energy resiliency in the Balkans.
- Bornhold Energy Island, a structure to turn the Baltic Sea into an “offshore interconnector hub”.
- South-East Europe, which will aim to improve price stability and energy security in southeastern Europe through grid investments and storage.
- The SouthH2 Corridor, which will deliver hydrogen between Tunisia, Italy, Austria and Germany.
- The Southwest hydrogen corridor, which will deliver hydrogen between Portugal and Germany.
These eight highways are all considered Projects of Common Interest (PCIs) and Projects of Mutual Interest (PMIs) under the TEN-E framework, and will assist shore up energy supply, and the transmission of green hydrogen, in parts of the bloc where such investments have been lacking or, in the case of the Baltic States, require additional urgency considering the recent actions of Russia and the decoupling of the Baltic grid from Russia’s in February.
Both the grids package and the eight highways were introduced by President Ursula von der Leyen yesterday, in her 2025 State of the Union address, and the proposal will now pass to the European Parliament and Council to consider the terms, but the Commission has not yet published a timeline for the next steps.
SolarPower Europe states the proposal ‘hits the nail on the head’
“The European Grids Package is more than just a policy,” declared Teresa Ribera, EU executive vice president for clean, just and competitive transition. “It’s our commitment for an inclusive future, where every part of Europe reaps the benefits of the energy revolution: cheaper clean energy, reduced depfinishence on imported fossil fuels, secure supply and protection against price shocks.”
“A truly interconnected and integrated energy system is the foundation of a strong and indepfinishent Europe,” added Dan Jørgensen, EU commissioner for energy and houtilizing. “This is exactly what we are proposing today: a common European energy project that supports affordable living, economic competitiveness, security and decarbonisation.”
The proposal also drew support from outside of the Commission itself; leading trade body SolarPower Europe declared that the proposed “grid connection guidance” would assist solar and storage project developers, in particular, connect projects to Europe’s growing grids.
“The Grid Connection Guidance is the highlight of the package, it hits the nail on the head,” declared SolarPower Europe CEO Walburga Hemetsberger. “This publication will assist Europe to build better utilize of the grid hardware that we have.”
However, Hemetsberger noted that the proposals lack a “vital spotlight on distribution system operators”, and that these stakeholders will required to be better compensated for integrating flexible generation technologies, such as solar, into their operations, rather than having to rely on expensive and time-consuming grid expansion work.
Other criticism includes the suggestion that the proposals see to ensure the position of “indusattempt incumbents” rather than deliver benefits for European citizens.
“The Grids Package takes some welcome steps to address lengthy connection queues; but does not address deeper governance challenges over the planning and operation of electricity grids in the EU,” declared Juliet Philipps, an energy campaigner at German non-profit Beyond Fossil Fuels. “Without tackling these issues, we risk investing in a system designed to favour indusattempt incumbents—rather than serve the public interest.”
“Europe risks trapping itself in a self-fulfilling prophecy, where fossil gas appears ‘necessary’ simply becautilize clean alternatives were never properly planned for,” Philipps continued. “We urge member states and MEPs to support stronger oversight measures to ensure national grid planning and investments are designed to secure homegrown renewable energy and storage projects that can rapidly displace risky and expensive fossil gas imports.”
