Power Stations

The Electricity Authority of Cyprus relies basically on imported fuels, mainly heavy fuel oil, for the production of electric energy. The Electricity Authority of Cyprus owns and operates three Power Stations with a total nominal capacity of 1118 MW as follows:

 Vasilikos Power Station  3 x 130 MW Steam units 390 MW
 Vasilikos Power Station  1 x 38 MW Gas Turbine 38 MW
 Dhekelia Power Station  6 x 60 MW Steam Units 360 MW
 Moni Power Station  6 x 30 MW Steam Units 180 MW
 Moni Power Station  4 x 37,5 MW Gas Turbines 150 MW
 Total Installed Capacity 1118 MW  

 

The Electricity Authority of Cyprus owns and operates three Power Stations with a total nominal capacity of 1118 MW as follows:

Dekelia Power Station: This Power Station is located on the south east coast of the island. Dhekelia Power Station consists of 6 x 60 MW conventional steam units burning heavy fuel oil. The first unit was commissioned in 1982 and the last one in 1993.

Dhekelia Power Station generated in 2006, 1.860.781 MWh which corresponds to 40,29% of the total electricity generated from the Authority’s Power Stations. During the same period, Dhekelia Power Station exported, 1.768.290 MWh which corresponds to 40,53% of the total electricity exported from the Authority’s Power Stations.

The thermal coefficient of efficiency of the Power Station for units generated reached 31,26% whereas the respective coefficient of efficiency for units exported reached 29,70%.

Moni Power Station: This Power Station is located on the eastern side of Limassol on the southern coast of the island. It consists of 6 x 30 MW conventional steam units burning heavy fuel oil and 4 x 37,5 MW diesel oil fired gas turbines. The first two steam units were commissioned in 1966 and the sixth in 1976. The first two gas turbines were installed in 1992 and the other two in 1995. The gas turbines are mainly used during system peak loading as well as emergency and stand-by plants.

Moni Power Station generated in 2006, 463.888 MWh which corresponds to 10,05% of the total electricity generated from the EAC’s Power Stations. During the same period the Station exported 434.180 MWh, which corresponds to 9,95% of the total electricity exported from the Authority’s Power Stations.

The thermal coefficient of efficiency of the Steam Units for units generated reached 25,04% whereas the corresponding thermal coefficient of efficiency for the Gas Turbines reached 23,42%.

Moreover, the thermal coefficient of efficiency of the Steam Units for units exported reached 23,42% whereas the corresponding thermal coefficient of efficiency for the Gas Turbines reached 21,39%.

Vasilikos Power Station: This Power Station is situated around 25 km east of Limassol on the southern coast of Cyprus. The first phase of the Station was commissioned in 2000 and consists of 2 x 130 MW heavy fuel oil/steam units and 1 x 38 MW diesel oil fired gas turbine which was commissioned back in 1999 and mainly serves as a black start unit. The second phase consists of 1 X 130 MW heavy fuel oil steam unit. This unit is also equipped with a Flue Gas Desulphurization Unit (FGD) for reducing the dioxide emissions below the limits set by the European Large Combustion Plants Directive.  

Vasilikos Power Station generated in 2006, 2.293.410 MWh, which corresponds to 49,66% of the total electricity generated from the Authority’s Power Stations. During the same period the Station exported, 2.160.237 MWh, which corresponds to 49,52% of the total electricity exported from the Authority’s Power Stations.

The thermal coefficient of efficiency of the Steam Units for units generated reached 39,22% whereas the corresponding thermal coefficient of efficiency for the Gas Turbines reached 23,45%.

Moreover, the thermal coefficient of efficiency of the Steam Units, for units exported, reached 36,95% whereas the corresponding thermal coefficient of efficiency for the Gas Turbine reached 20,49%. 

On July 11th 2011, due to an explosion at the adjacent Mari Naval Military Base, Vasilikos Power Station suffered extensive damage which has caused the complete interruption of its operation.   

Immediately after the incident a series of decisions and actions were taken to install and operate temporary generating units. The installation and operation of existing standby generators was mandated by the Energy Regulator.  To that extend the Electricity Authority of Cyprus has collaborated closely with the generator owners, offering technical support and planning.

The Israel Government offered standby generators, totaling 15MW, which were installed on the distribution networks within the 2nd week after the incident.

An agreement was reached for the supply of up to 120 ΜW from a Power Company operating in the Turkish Occupied Areas.  This supply was made possible under the green line trade collaboration between the two communities.  Initial connection took place on the 16th July 2011 and the current agreement expires on the 29th February 2012.

The Greek Government, through the Public Power Company (PPC), has mobilized 71,6 ΜW of temporary generating units.  These units were installed in the Vasilikos Power Station Area, and have been operating since 14th August.  The lease contract has since been extended by EAC for an additional 6 month period.

The Vasilikos Power Station Black Start Gas Turbine (38 MW) was restored and put in operation by August 17th.

The Electricity Authority of Cyprus has contracted, in accordance with the Cyprus Energy Regulating Authority Decision, temporary generating units with a total capacity of 95 ΜW, for a six month period.  The initial request for proposal was issued on July 13th and contract award was on July 30th.  These generators have been in operation in Dhekelia and Moni Power Stations since late August.

The combination of the above measures has ensured that the electricity system has enough, albeit marginal, capacity to meet the electricity demand, and the rotating power cuts have effectively stopped since mid August.

The Electricity Authority of Cyprus is proceeding with the restoration of the Vasilikos Power Station, and to that effect a large Restoration Project Team has been established.  The mission of the Project Team is the speedy, safe and cost effective return of the station to full operation.

Though the final restoration schedule is still being developed, as the detailed damage assessment is still ongoing, the targets of the restoration are set with an aim to reduce the economic effects, mainly by reducing the electricity cost to its prior level, the soonest possible.
