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 MW
2.
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’s
energy)
• Units operating to generate the above capacity:
•
•
UNIT 1, 2 & 3
UNIT 4
Gas turbine Unit 5*
3x130MW = 390 MW
1x220MW = 220 MW
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 members
of staff covering operational, administrational
and maintenance aspects.
• In view of the frequent extended dry seasons in
Cyprus, EAC was granted permission for the
construction of a SW-RO Desalination Plant
60000 m3/day at Vasilikos Power Station taking
advantage of the co-location synergies between
the Power Station and the Desalination Plant.
• The Plant was planned to be completed in
February 2013.
Vasilikos Power Station
as a Seveso Establishment
The E.U. SEVESO II Directive
• Requires for establishments handling dangerous
substances, to take all measures necessary to prevent
major accidents and to limit their consequences for the
people and the environment.
•
Vasilikos Power Station has to implement the Seveso II
Regulations due to the storage of 69000 tones of diesel
oil and 1.9 tones of Hydrazine [35% concentration]
(upper Tier)
• Vasilikos Power Station Established:

IMPACT
ON VASILIKOS POWER
STATION
BEFORE THE INCIDENT
VASILIKOS POWER PLANT (before explosions)
•
Vasilikos Power Station is the newest of the 3 Power Stations
operated by EAC. It is located on the SE coast between
Larnaca and Limassol.
•
The Station is manned by about 152 persons and includes
Administration, Operation and Maintenance Departments.
Shift personnel man the Plant 24 hrs a day on a 5 cycle (3x8
hrs) shift roster.
•
The Station has been provided with a Health and Safety
Officer to support the development and implementation of Site
Health and Safety policies and procedures.

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 were
confiscated 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.
VASILIKOS POWER PLANT
(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 on
the 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 the
Cyprus Fire Brigade. Twelve (12) fire
appliances and thirty (30) fire fighters were
involved.
• The environment impact of the accident was
low as no major releases were experienced.
Small scale spillages of substances like
lubricants and fuel occurred inside buildings,
but were effectively collected and stored by
the 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 and
access restricted.
• All personnel, visitors and contractors received Safety
Induction Course on arrival. This Induction Course
provided information and details of the hazards on site
and what to do in case of an emergency.
• Basic sanitary facilities were established
• Removal of all Heavy Fuel Oil in the HFO Tanks
and exported to Dhekelia and Moni Power
Stations
• Transfer of chemicals to safer locations e.g.
Hydrazine
• EAC developed an overall Health and Safety Plan
for the site in conjunction with the main
contractors.
• A Cyprus Fire Brigade fire team was stationed at
the Power Station until the 15th November, 2011
when the Station Fire System was repaired.
• First Aid arrangements were made.
• EAC personnel Fire Assembly Points were
revised.
• EAC Emergency Plan Arrangements were
reviewed.
• Police Experts checked and cleared for explosive
Ordinance Disposal.
• Permit for Hot Work and Electrical Work were
issued.
• Health & Safety Officer supported by 2 more
officers.
• Removal of dangerous falling objects (e.g.
claddings), and cleaning of the main access road.
Immediate measures to cope with
electricity demand/supply problems
1. Dhekelia and Moni Power Stations
-All generating units made available
-All personnel summer annual leaves withdrawn
2. Black Start Gas Turbine (38MW) was employed
since it didn’t suffer severe damages.
3. Temporary Generators (total capacity 180MW)
were hired and installed.
4. 120MW made available from Turkish occupied
areas.
5. EU Civil Protection mechanism
• Mechanism activated on July 13th 2011
• 15 ECP experts arrived on the island on July 16th
2011
• Largest team ever deployed by the mechanism
within EU
• Mission Risk assessment
• Health & Safety Issues
• Damage assessment
• Evaluation of reconstruction costs
• The mechanism experts report was submitted on
July 27th 2011
6. Electricity consumption savings by appealing to
the consumers via the mass media.
7. Power interruption by rotation (consumers divided
to 22 groups with interruption time 2-2.5 hours)
8. Main target: to maintain all economic activity
giving priority to:
-Tourist Industry
-Industrial zones
-Basic services
Interruption measures removed: August 14th 2011
Vasilikos Power Station
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
VASILIKOS POWER PLANT
CURRENT SITUATION
Current Situation
• The organizational structure at the site is
currently the existing operational Power Station
structure, supplemented by contractors who are
working on the restoration sites.
• Most of the main Fire System is operative.
• Chemical substances have been transferred to
Moni 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 risk
assessments and method statements adapted at any
risks of work that will be executed at the construction
site.
• Smoking is strictly prohibited at all areas of Vasilikos
Power Station with the exception of designated areas.
• Induction course is given to the Contractors Safety
Coordinators by the EAC Safety Officer prior to works
commencing. The contractors give induction courses to
their personnel. Newcomers are inducted by the
contractor Safety Coordinator. A list of those inducted is
issued 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)
Dear guest
Thank you for your patience.
We wish you a pleasant visit at
