Future Development
Internal Combustion Units of Dhekelia Power Station
· On the 3rd of August 2007, during a meeting carried out under the Minister of Commerce, Industry & Tourism and participated by CERA and the Electricity Authority, the subject of electrical generation reserve for the summer 2008 was studied on the basis of the increased demand which prevailed during the summer period of 2007. CERA commissioned EAC to find out generation units of 50-60 MW capacity. The Electricity Authority undertook to proceed with the requisite procedures so that by June 1st 2008 would be in a position to offer the increased reserve requested of it during the said meeting.
· Following an urgent tendering procedure the contact was awarded to the company Burmeister & Wain Scandinavian contractor A/S of Denmark for the installation of a temporary power station for increasing the system reserve during the summer 2008 and after that for the installation of the permanent power station using internal combustion engines by the 1st of June 2009. The temporary installation which has already been installed consists of 60 small units with a generation capacity of 50 MW whereas the permanent installation will comprise three units of 17,48 MW capacity each with an expected total capacity of 52,44 MW.
· The engines of the temporary installation use Eurodiesel as fuel with maximum sulphur content 0.1%. The engines will be used as a reserve with a very low probability of operation. The engines of the permanent installation will use heavy fuel oil as fuel.
· The Authority has carried out an Environmental Study for both the temporary as well as the permanent installation of the internal combustion engines in order to assess any environment impacts. The results of the model indicate that the operation of both the temporary as well as the permanent installation will not exceed the values set in the E.U. Directives regarding ground level concentrations of emissions. As regards the levels of gas emissions these have been specified by the Competent Authority and it is expected that they will be adhered to fully. Also the environmental impacts from the installation in connection with water quality are not considered important.
Third Phase of Vasilikos Power Station :
- Phase III consists of one combined cycle Unit with a capacity of 220 MW, (Unit No. 4), which is expected to be put in commercial operation at the beginning of 2009. In the Contract there is a provision for the operation of two open cycle gas turbines in May 2008. During the first years of operation of the unit, it will use as fuel diesel oil until liquefied natural gas (LNG) is imported in Cyprus. Thereafter it will use liquefied natural gas as the main fuel.
- For this Project, the method of a completed contract (Turn Key) will be followed that will include the planning, the supply, the manufacture, the construction, the tests, the delivery and the maintenance of the Unit for a specified time period. This is the usual practice that is applied internationally for Combined Cycle Units.
- The Contract for the construction of Phase III has been awarded to the joint venture Hitachi Power Europe/Itochu Corporation & J&P Avax.
- For the maintenance of the two gas turbines a Contract has been awarded to General Electric International Inc. The Contract provides for the maintenance of the gas turbines for a period of 9 years.
Fourth Phase of Vasilikos Power Station :
- Phase IV consists of two dual firing (liquefied natural gas and diesel) combined cycle Units with a capacity of 170-220 MW each (Units No. 5 and 6).
- For this Project, as in the case of Phase III, the method of a completed contract (Turn Key) will be followed.
- The Consultants of the project, Lahmeyer International GmbH of Germany,
have submitted to the Electricity Authority of Cyprus their final report which refers to the total review of the Generation Development Program and its formation so that it will be successfully implemented in the liberalized electricity market.
The report was submitted in November 2006 and thereafter, the Business Unit Generation, after considering the best applicable scenario as well as other parameters analyzed in the report, prepared and submitted a specific proposal to the Board of Directors which was eventually approved on the 6th of December 2006. According to the approved proposal, Unit No. 5 will be regarded as a definite Unit and will be delivered for commercial operation in April 2011 whereas Unit. No. 6 in 2012.
Summarized Development program*
(1) COMMISSIONING OF DIESEL POWER PLANT 50 MW (June 2008)
(2) COMMISSIONING 1 x 220 MW (COMBINED CYCLE UNIT, VASILIKOS)- 2009(beginning)
(3) COMMISSIONING 1 x 220 MW (COMBINED CYCLE UNIT, VASILIKOS) - 2011 (beginning)
(4) COMMISSIONING 1 x 220 MW (COMBINED CYCLE UNIT) – 2012 (beginning)
(5) DE-COMMISSIONING 6 x 30MW = 180MW (STEAM UNITS, MONI) - 2012 (end)
It is estimated that the steam units at Moni P/S will be taken out of service at the end of 2012. Thereafter, the land will be suitably prepared for the installation of new combined cycle units (2016).
