Power Stations
Cyprus does not have primary sources, so the Electricity Authority of Cyprus (EAC) is based on the generation of electricity exclusively on imported fuels, mainly crude oil. Currently, the EAC has three power stations with a total installed capacity of 1598 MW as below (in parentheses the expected date of recovery):

The Electricity Authority of Cyprus owns and operates three Power Stations:
Dhekelia Power Station: The station is located on the southeastern coast of Cyprus. The Dhekelia Power Station, with an installed capacity of 460 MW (6 x 60MW Steam turbines and 100 MW Units Internal Combustion) produced during the 2011 54,17% (2 560 819 MWh) of total electricity generated by the power stations of the Authority, while during the same period, export the 54,38% (2 451 879 MWh) of total electricity exported from the Generating Stations Authority.
The thermal efficiency of the steam units stood at 30.70% and the thermal efficiency of the Internal Combustion Units stood at 42.16%. The thermal efficiency of the steam units in unit export stood at 29.15% and the thermal efficiency of the Internal Combustion Units stood at 41.30%.
Moni Power Station: The station consists of four (4) steam units of 30 MW capacity each, fueled by heavy fuel oil and four (4) of 37,5 MW gas turbines fueled with gas oil (diesel). The first two steam units operated in 1966 and the last in 1976. The two turbines were added to the system in 1992 and two in 1995, mainly used for addressing peak loads and for emergencies.
The Moni Power Station in 2011 produced 10,91% (515 518 MWh) of the total electricity generated by all power stations of the Authority, while during the same period, exported 10,89% (490 822 MWh) of the total electricity exported from the Generating Stations of the Authority.
The thermal efficiency of the steam units stood at 25.47% and the thermal efficiency of gas turbines stood at 26.09%. Also, the thermal efficiency of the steam units export stood at 23.98% and the thermal efficiency of gas turbines stood at 25.84%. The turbines of Moni Power Station have been set to ‘standby’and will only operate, if needed, to cover unforeseen incidents.
Vasilikos Power Station: The Vasilikos Power Station is the largest infrastructure project ever built in Cyprus. The importance of this key infrastructure project is closely intertwined with the wider economic development of Cyprus.
This ‘state of the art’ power station consists of:
· Three steam units 130 MW each fueled by heavy fuel oil. In one of the units a flue gas desulphurisation system has been installed in order to reduce the emissions of sulfur dioxide below the emission limits set by the European Directive for Large Combustion Plants.
· A 38 MW gas turbine powered with gas oil (diesel).
· Two combined cycle units 220 MW each, fueled withgas oil (diesel) that can be converted to be fueled by natural gas.
On July 11, 2011 due to an explosion at the naval base in Mari, the nearby Vasilikos power station suffered heavy losses which had resulted in the complete suspension of its operations.
The EAC personnel, along with the developers of the projects, have successfully repaired most of the station. Remaining inoperative are the three conventional units with a total capacity of 390 MW, due to ongoing repairs of the damages suffered after the explosion of July 11, 2011. The restoration works of the combined cycle unit No. 4 are in the final stage and is expected to be in operation before the end of December 2012. It is expected that the unit No. 3 will be operational in early 2013 and the units No. 1 and No. 2 will be operational in June 2013.
The Vasilikos Power Station produced during 2011 34,92% (1 650 547 MWh) of the total electricity generated by the power stations of the Authority, while during the same period, exported 34,73% (1 565 802 MWh) of the total electricity exported from the power station of the Authority. It should also be noted that the Combined Cycle Unit No. 5 overall capacity of 220 MW operated from July 1, 2011 in open cycle (with a capacity of 145 MW) until July 11 that the explosion happened.
The thermal efficiency of the steam units stood at 38.63% and that of the Combined Cycle Unit No. 4 at 45.15% while the thermal efficiency of the gas turbine stood at 18.77%. Also, the thermal efficiency of the steam units, export amounted to 36.27%, that of the combined cycle unit No. 4 at 43.77% and the thermal efficiency export of the gas turbine stood at 17.84%.
