Europe does not lack ambition in the energy transition.

Renewable capacity is growing. Investments are accelerating. Infrastructure is moving higher on the policy agenda.

But the question is becoming less about how much we build and more about how well we coordinate what we build.

In February, we looked at a Bruegel policy brief on the efficiency of the European energy system. Its main point is direct: as electrification advances, Europe’s energy efficiency will depend increasingly on open data, integrated grid planning and better alignment between national plans.

This matters because energy systems no longer function as isolated national structures. Power flows across borders. Grid constraints in one area can influence prices and balancing needs elsewhere. Investment decisions made nationally can create regional consequences.

The real challenge is integration.

Networks planned mainly through national logic need to support regional flows. Renewable projects need grid capacity. Flexibility mechanisms need better coordination. Market signals need to reflect system realities, not only individual project economics.

When coordination is weak, the same symptoms appear repeatedly: congestion, redispatching, higher balancing costs, evacuation limits, volatile price signals and greater exposure to system imbalances.

These are no longer occasional episodes. They are becoming part of day-to-day energy system management.

Bruegel’s policy brief points to three clear directions: more open and comparable data, genuinely cross-border network planning and stronger alignment between national plans and policies.

For Romania and the wider region, this is immediately relevant.

When renewable capacity develops faster than grid reinforcement and flexibility mechanisms, bottlenecks appear. Energy that could support the system becomes harder to evacuate. Prices can shift abruptly. Forecasting, balancing and trading strategies become more exposed to uncertainty.

For trading, this means that good information and good coordination are practical risk management tools.

They are the difference between a strategy that can withstand volatility and one that breaks at the first shock.

That is why digitalisation, data quality and modelling discipline matter. They sit alongside infrastructure and clear rules as essential tools for managing an increasingly complex energy market.

A better coordinated energy system is not only a policy objective. It is a condition for efficiency, resilience and lower transition risk.

As Europe continues to build renewable capacity, the next stage will depend on the quality of the system around it: grids, data, planning, flexibility and the ability to make decisions across borders.
