PPC Group is strengthening the adequacy and security of electricity supply on Rhodes and Kos by installing four new gas turbine units with a combined capacity of 58 MW at the power stations on the two islands.
Work to install the two units at Soroni on Rhodes is already under way, while work on the corresponding units at the Kos power station is expected to begin in October. On Rhodes, this is the third upgrade at the Soroni plant; the previous two were completed over the past two years. The new units on Rhodes and Kos are due to start operating in summer 2027. They are four Titan 130 units, each with a rated capacity of 14.5 MW and an efficiency of 33%-34%. The units are dual-fuel and incorporate technologies to limit emissions of gaseous pollutants and particulates.
A key feature of the new, flexible units is their ability to start up quickly. They take about 10 minutes to start up and reach their rated capacity, enabling them to respond immediately to changes in demand and the needs of the electricity system. The SoLoNOx technology they use limits emissions of nitrogen oxides (NOx) and carbon monoxide (CO), without requiring water injection.
At the same time, replacing heavy fuel oil (HFO) with diesel (LFO), combined with the emissions-control systems, is expected to help reduce the power stations’ environmental footprint. Noise levels from the new units will not exceed 65 dB at the boundaries of the stations.
The installation of the new units is expected to increase the generating capacity of the power stations on Rhodes and Kos, strengthening the energy supply adequacy of both islands. Their operation as flexible generating units will allow them to meet the system’s needs quickly and operate alongside renewable energy units.
At the same time, the increase in available generating capacity is expected to strengthen the energy supply adequacy of Rhodes and Kos and help reduce the cost of Public Service Obligations (PSOs).
The two new projects at Soroni on Rhodes (Phase III) and on Kos form part of PPC Group’s wider plan to upgrade power-generation infrastructure on the islands and make the electricity system more flexible. In 2025, similar modernisation projects were completed at PPC power stations on Santorini, Rhodes (Phase I) and Crete, while earlier this year work was completed on Rhodes (Phase II), Chios and Lesbos.
With its new Strategic Plan for 2026-2030, worth €24 billion, PPC Group continues to invest systematically in a new energy model based on flexibility, technological innovation and interconnections. Large-scale renewable energy development is being combined with investment in storage systems and flexible power generation, as well as energy management solutions using artificial intelligence tools to improve the stability and efficiency of the system.
