EU Underground and Submarine Power Cables Cartel
1999–2009 · power cables, grid infrastructure, offshore wind
High-voltage power cables linking countries and offshore wind farms are multi-million euro projects. EU regulators said cable giants rigged bids for a decade—inflating costs for electricity grids consumers depend on.
The story
Europe invests heavily in underground and submarine cables to connect national grids and bring offshore wind ashore. Few suppliers can execute turnkey projects, creating oligopoly conditions.
The Commission found Prysmian, Nexans, NKT, and formerly ABB (immunity recipient) colluded on project allocation and pricing rather than competing head-to-head.
Cartel conduct allegedly included knowing who would 'win' each tender and submitting complementary cover bids to simulate competition for grid operators.
Raids in 2009 followed whistleblower cooperation; investigators reconstructed bid patterns across Scandinavia, the Baltic, and Mediterranean projects.
2014 fines totaled €302 million—smaller than trucks or CRT but critical for energy infrastructure economics.
Higher cable project costs feed into network tariffs and renewable transition budgets—socialized through electricity bills.
The case underscores EU vigilance on green-transition inputs, not only legacy industries.
Why it matters
Energy transition infrastructure can be cartelized too.
Bid rigging on public grid projects taxes ratepayers.
Immunity tools unlock submarine-project secrets.
What was claimed
Bid rigging on high-voltage cable projects.
Market sharing among top European suppliers.
Harm to TSOs and offshore wind developers.
The other side
Firms appealed fine calculations.
Complex project pricing defended as independent in damages suits.
What it means for you
Electricity network costs reflect competitive—or collusive—cable bidding.
Renewable expansion depends on honest procurement.
Bottom line
The power cables cartel rigged bids on projects wiring Europe's grids and offshore wind—fined €302 million for a decade of collusion.

Formal snapshot
Summary: The Commission fined major cable makers €302 million for colluding on high-voltage underground and submarine power cable projects critical to grid infrastructure and offshore wind.
Regulator / plaintiff argument: Prysmian, Nexans, NKT and others rigged bids for turnkey cable projects, sharing contract opportunities and prices across Europe.
Outcome: 2014 fines; leniency applicant received reduction; grid operators pursued damages.
Remedies: Fines; compliance training; damages litigation.
