Advancing Energy Security And The Green Transition
In a decisive move towards enhancing energy security and accelerating the green transition in Cyprus, the Electricity Authority of Cyprus (EAC/AHK) is modernizing its Dekeleia Power Station. With a substantial investment of €180 million, the authority is spearheading the installation of new generation units and advanced energy storage systems, marking a pivotal step away from aging, high-emission steam turbines.
Comprehensive Investment And Environmental Oversight
The project, which integrates state-of-the-art Open Cycle Gas Turbines (OCGT) capable of operating on diesel initially and transitioning to natural gas as it becomes available, showcases both flexibility and a clear path toward cleaner energy solutions. The initiative is currently subject to an Environmental Impact Assessment (EIA), with formal public consultations scheduled to conclude on February 28, 2026. This transparent process ensures that all stakeholders are informed as AHK modernizes its infrastructure.

Enhancing Production Capacity And System Reliability
The proposed expansion involves deploying a new OCGT unit with a capacity between 60 and 115 MWe. Designed to boost production capability and system stability, this unit is expected to significantly reduce the carbon footprint of the Dekeleia facility. Ultimately, the project aims to gradually retire the outdated steam turbines, thereby curtailing emissions and aligning with broader environmental goals.
Integration Of Advanced Battery Energy Storage
A central element of the project is a 160 MWh Battery Energy Storage System (BESS). The system is intended to stabilize the grid and enable greater use of renewable energy. It will consist of modular battery units, likely based on lithium iron phosphate or similar technology, housed in prefabricated enclosures with cooling, flame detection and fire-suppression systems.
Robust Operational And Safety Measures
The new OCGT unit and planned natural gas supply system will be located within the existing Dekeleia site, primarily on the western side of the plant. The facility operates under SEVESO safety regulations, which are designed to limit the impact of potential industrial incidents. Additional safeguards include selective catalytic reduction (SCR) systems to reduce NOx emissions and leak-prevention measures.
Financial Strategy And Broader Impacts
The modernization project is financed through the authority’s reserve resources, with significant backing from the European Investment Bank (EIB) via grants. This strategic financing not only upgrades critical infrastructure without adding to public debt, but it is also projected to yield lower electricity prices for both households and businesses. Currently, the Dekeleia Power Station contributes approximately 34.5% of AHK’s total electricity production, emphasizing its central role in Cyprus’s energy framework.
A Legacy in Transition
The Dekeleia facility, operational since 1953, has evolved from the pioneering Dekeleia A, with its early 84 MW capacity, to the larger Dekeleia B complex consisting of six conventional steam turbine units with a combined capacity of 360 MW. Supplementary internal combustion units (MEC 1 and MEC 2) further bolster production, ensuring the facility’s adaptability to rising energy demands. As the transition to modern OCGT and cleaner fuels gathers momentum, the legacy infrastructure that once defined Cyprus’s energy production is being reimagined for a sustainable future.
Looking Ahead
This transformative project underscores AHK’s commitment to a robust, reliable, and environmentally responsible energy system. With technologically advanced generation units, integrated battery storage, and rigorous safety measures, the Dekeleia Power Station stands at the forefront of Cyprus’s journey towards a cleaner and more efficient energy landscape. The strategic modernization not only meets current demands but also paves the way for the future integration of renewable sources, ensuring long-term stability and reduced environmental impact.
