Europe's Next Energy Challenge Is Not Generation, But Consumption

Renewable energy demand is becoming one of the defining challenges of Europe’s energy transition. As Southeast Europe rapidly expands solar and wind capacity, the question is no longer only how to generate more clean electricity, but how to ensure there is enough demand to use it efficiently.

For much of the past decade, Europe’s energy transition has focused primarily on increasing renewable generation.

At Balkan Battery Day 2026, however, the discussion around battery storage revealed a broader challenge emerging beneath the surface. During the panel on integrating BESS with renewables and the wider energy system, speakers explored what happens if Europe succeeds in building vast amounts of clean electricity without creating sufficient demand to absorb it.

Moderated by Kostis Geropoulos, Co-founder and Director of Energy & Climate at NE Global, the panel brought together experts from across the renewable energy sector, including Athanasios Plainos (LONGi Solar), Efstathios Sideris (Econergy Group), Horia Grigorescu (Grigorescu Partners), Răzvan Copoiu (ENEVO Group) and Tasos Mantzaras (Rokas Renewables).

The discussion suggested that Europe’s next challenge may not be producing more renewable electricity, but redesigning demand around it.

Renewable Overproduction Is Becoming a Structural Challenge

Across Southeast Europe, solar deployment has accelerated rapidly.

The consequences are becoming increasingly familiar across regional electricity markets:

• midday oversupply
• negative electricity prices
• renewable curtailment
• transmission congestion
• balancing volatility

Battery storage is helping manage part of this imbalance, but several panellists argued that storage alone cannot fully resolve the long-term mismatch between renewable production and electricity consumption.

Athanasios Plainos, Key Accounts Sales Manager Greece & Cyprus, LONGi Solar, noted that today’s lithium-ion battery systems primarily solve short-duration flexibility challenges rather than seasonal differences between summer renewable generation and winter electricity demand.

The discussion therefore raised a broader question: how should renewable energy demand evolve alongside renewable generation?

Data Centres Could Become a Strategic Source of Renewable Energy Demand

One of the most interesting themes discussed was the growing importance of large electricity consumers.

Răzvan Copoiu, Deputy CEO, ENEVO Group, argued that Europe will increasingly require new energy-intensive industries capable of absorbing large volumes of renewable electricity.

The sectors highlighted during the discussion included:

• AI infrastructure
• hyperscale data centres
• hydrogen production
• desalination
• digital manufacturing

As artificial intelligence continues to expand globally, electricity demand from data centres is expected to become one of the fastest-growing sources of electricity consumption.

The panel also referenced examples such as Saudi Arabia, where renewable deployment is increasingly planned alongside anticipated demand from large digital infrastructure projects.

Rather than developing generation first and demand later, this approach aligns renewable investments with future industrial consumption.

Renewable Energy Demand Requires Industrial Strategy

The discussion also explored whether Europe’s industrial development is keeping pace with renewable deployment.

Several speakers suggested that renewable energy demand may become just as important as renewable generation itself.

Without sufficient industrial electricity consumption, Europe risks creating large volumes of renewable capacity that cannot be fully utilised.

This issue is particularly relevant across Southeast Europe, where renewable resources continue to expand while industrial demand remains uneven between markets.

Future competitiveness may therefore depend not only on producing clean electricity, but also on attracting industries capable of using it effectively.

Examples discussed included:

• green manufacturing
• hydrogen production
• energy-intensive industries
• digital infrastructure
• cross-border electricity exports

Energy Security Is Entering a New Phase

The discussion also highlighted how Europe’s understanding of energy security continues to evolve.

The acceleration of renewable deployment was driven partly by the need to reduce dependence on imported fossil fuels following Russia’s invasion of Ukraine.

However, several panellists noted that new forms of dependency are emerging.

Europe continues to rely heavily on imported clean energy technologies, particularly batteries, solar modules and related components manufactured outside the continent.

This creates a difficult balance between:

• accelerating renewable deployment
• reducing external dependency
• maintaining competitive costs
• strengthening European manufacturing

The discussion suggested that these objectives will increasingly shape future industrial policy.

Cybersecurity Is Becoming Part of Renewable Infrastructure

Towards the end of the discussion, another topic emerged that is becoming increasingly important for renewable energy systems: cybersecurity.

As battery storage systems, inverters and renewable assets become more digitally connected, protecting critical energy infrastructure is becoming an operational priority.

Several panellists referred to Europe’s evolving cybersecurity framework, including NIS2, as evidence that policymakers increasingly recognise renewable infrastructure as strategically important.

Future renewable deployment will therefore require expertise extending beyond engineering and finance to include cyber resilience and digital infrastructure protection.

The Next Phase of the Energy Transition Will Be Defined by Integration

Perhaps the strongest conclusion from the discussion was that Europe’s energy transition is becoming significantly more complex than replacing fossil fuels with renewable generation.

The next phase depends on successfully integrating:

• renewable generation
• battery storage
• industrial demand
• digital infrastructure
• transmission systems
• cybersecurity
• regional cooperation

The challenge is no longer simply deploying renewable capacity.

It is designing an electricity system where generation, storage and renewable energy demand evolve together.

As renewable penetration continues to increase, Europe’s success will depend not only on how much clean electricity it can produce, but also on how effectively it can consume it.
