Should nations continue funding large-scale energy projects that experience repeated delays and rising budget costs?
The construction of the electricity interconnector between Cyprus and Greece is delayed, with the new completion date set for January 1, 2031. This timeline shift follows technical information provided by cable manufacturer Nexans and pending seabed surveys.
Why it matters
The project is critical for regional energy infrastructure and is projected to exceed a cost of 1.9 billion euros over its 50-year lifespan. Final costs remain subject to the completion of seabed surveys which currently account for 45 million euros in spending.
The project is slated to generate an 8.3 percent return for the first 17 years and 4.6 percent for the subsequent 17 years. Operators have already manufactured 170 km and 280 km sections of cable.
The players
IPTO
The independent power transmission operator is responsible for managing the electrical grid and implementing the interconnector project.
Nexans
The company is a global manufacturer of power cables and related systems that is supplying the specialized subsea infrastructure.
The details
The delay stems from technical data supplied by Nexans, which requires further seabed surveying to finalize construction requirements. Regulators from Cyprus and Greece continue to coordinate with project operator IPTO regarding ownership structures and market impact studies.
Timeline
August 2026: Cyprus and Greece regulators sent a joint letter to IPTO.
November 5, 2026: Scheduled meeting regarding the Israel investment request.
January 1, 2030: Original scheduled completion date.
January 1, 2031: New scheduled completion date.
Market Landscape
This project integrates isolated regional energy grids into the broader European electricity market to ensure long-term supply stability. It represents a significant expansion of cross-border infrastructure that aligns with the European Network of Transmission System Operators for Electricity's 10-year network development plan.
The delay postpones the expected stabilization of electricity markets in the region. Consumers and energy stakeholders must wait until 2031 for the full operational capacity of this cross-border power link.
The takeaway
Large-scale energy infrastructure projects often face significant timeline adjustments due to complex technical and surveying requirements. Stakeholders should anticipate that final budgets for such projects frequently evolve as foundational geological data is gathered.
What happens next
A meeting with representatives regarding the potential Israel investment request is scheduled for November 5, 2026.
