Cyprus Power Generation

System(data from year 2010)

• Electricity production is the responsibility of the

Electricity Authority of Cyprus (EAC), which is

an independent semi-government corporation.• EAC operates three power stations:

1. Moni Power Station : 330 MW2. Dhekelia Power Station : 462 MW

3. Vasilikos Power Station : 648 MW



• Total installed capacity before the

explosion was 1440 MW within Cyprus.

• Annual Generation: 5205GWh

• Peak Demand: 1148MW

• Power generation system is small and

isolated with no interconnections.



EAC Power Stations



Vasilikos Power Station Before

the Explosion

• Capacity: 788MW (approximately 60% of the country’senergy)

• Units operating to generate the above capacity:

• UNIT 1, 2 & 3 3x130MW = 390 MW

• UNIT 4 1x220MW = 220 MW

• Gas turbine Unit 5* 2x70MW = 140 MW

• Gas turbine Black Start 1x38MW = 38 MW

--------------788 MW

========• * Unit 5 under test period. Excluded from installed capacity



• Vasilikos Power station employs 152 membersof staff covering operational, administrational

and maintenance aspects.

• In view of the frequent extended dry seasons in

Cyprus, EAC was granted permission for theconstruction of a SW-RO Desalination Plant60000 m3/day at Vasilikos Power Station takingadvantage of the co-location synergies betweenthe Power Station and the Desalination Plant.

• The Plant was planned to be completed inFebruary 2013.



Vasilikos Power Station

as a Seveso Establishment

JUST AFTER THE EXPLOSION INCIDENT

AT THE ADJACENT

EVANGELOS FLORAKIS NAVAL BASE

(11TH JULY 2011)













VASILIKOS POWER PLANT

(after the explosions)

• On July 11th 2011, a series of explosions took place

soon after 03:00 and a severe shock wave occurred at

5:48 am.

• It has been estimated that the explosion was of a

magnitude equivalent to ~ 400 tones of TNT.• This was due to explosives and other material(gun

powder, propellants and metal parts for the

manufacturing of ammunition) stored in a pile of 98

containers at the naval base. These containers wereconfiscated by the Government of Cyprus at Limassol

Port on its way to Syria (February 2009), in compliance

with a UN Security Council resolution enforcing an arms

embargo against Syria.




(after the explosions)

• Thirteen (13) people were killed and 65 were

injured, including twelve (12) members of the

Power Station Night Shift personnel

• The neighboring Vasilikos Power Plant (500 m)

was severely damaged. A hill about 30 meters

high was a barrier and prevented a complete

destruction of the Plant.



VASILIKOS POWER PLANT (after the explosions)

• The blasts resulted in an uncontrolled shutdown

of the generating Units of the Station.

• Fires broke out in the Administration building,

Turbine hall, contractor’s area and the trees onthe hill west of the Station due to hot molten

metal pieces, landing on them. Fortunately the

metal pieces did not ignite the HFO or DFO

tanks.

• The affected area around the explosion site, was

around 8km2 where about 4.200 people are

living.



• The fires were brought under control by theCyprus Fire Brigade. Twelve (12) fire

appliances and thirty (30) fire fighters wereinvolved.

• The environment impact of the accident waslow as no major releases were experienced.Small scale spillages of substances like

lubricants and fuel occurred inside buildings,but were effectively collected and stored bythe station’s personnel



Serious threat to personnel/visitors/contractors

• The main Fire System was not operative.

• Transfer fuel oil from damaged Tanks• Falling objects (cladding) from heights.

• Dust in the atmosphere from insulation materials

• Openings all over the plant

• Major structures were critical for collapsing

• Munitions fragments scattered all over in the Plant

• Hazardous substances:

- fuels (flammable)

- H2SO4 (corrosive)

-Hydrazine (toxic)

-dust



IMMEDIATE MEASURES TAKEN TO COPE

WITH THE CRISIS ON SITE

• Survey of all buildings by civil engineers team

• All buildings were secured with suitable fencing andaccess restricted.

• All personnel, visitors and contractors received SafetyInduction Course on arrival. This Induction Course

provided information and details of the hazards on siteand what to do in case of an emergency.

8. Main target: to maintain all economic activity

giving priority to:-Tourist Industry

-Industrial zones

-Basic services

Interruption measures removed: August 14th 2011




Restoration Project • For the restoration of the station, the

largest team in the history of EAC was

assembled.• The main aim was the safe, quick and

cost effective restoration of the Power

Station.





Restoration Program




CURRENT SITUATION

C t Sit ti



Current Situation

• The organizational structure at the site iscurrently the existing operational Power Stationstructure, supplemented by contractors who areworking on the restoration sites.

• Most of the main Fire System is operative.

• Chemical substances have been transferred toMoni and Dhekelia Power Stations.

• A Temporary Emergency Plan was developed

and implemented.



• All main contractors have a Health & Safety Plan in

place and a Safety Coordinator, written riskassessments and method statements adapted at anyrisks of work that will be executed at the constructionsite.

• Smoking is strictly prohibited at all areas of VasilikosPower Station with the exception of designated areas.

• Induction course is given to the Contractors Safety

Coordinators by the EAC Safety Officer prior to workscommencing. The contractors give induction courses totheir personnel. Newcomers are inducted by thecontractor Safety Coordinator. A list of those inducted isissued against their signature.







SUGGESTIONS FOR MEASURES

IS SEVESO II & III “STRONG” ENOUGH?

FULFIL IT’S “SUBJECT MATTER”?

MILITARY INSTALLATIONS ARE EXCLUDED BY THE SEVESO

DIRECTIVE AND THIS IS SOMETHING THAT NEEDS, IN MY OPINION,

TO CHANGE.

Include military establisments in the Seveso regulation for:

• Land Use planning (SEVESO III, Reg. 13)

• Domino effect (SEVESO III, Reg. 9)
