Enguri hydropower plant... |

...covers 40 per cent of Georgia's power needs. |

No more power cuts in Tbilisi. |
Power cuts were the daily routine in post-Soviet Georgia, with blackouts
lasting for as long as two weeks. They became emblematic of the country’s
precipitous economic decline, played out in degraded living standards in what
was once one of the USSR’s most prosperous republics.
Households, businesses, hospitals and schools had to make do, or die. On the
home front they substituted with often-faulty gas heaters (one of which killed
Prime Minister Zurab Zhvania in 2005). Or they financed their own private
generators, or paid bribes, in the case of some bigger industrial concerns, to
ensure scarce power from the central system was diverted to them.
Since 1998 the EBRD and the European Commission (EC) have been helping to
unpick the knots in Georgia’s energy supply, in part by investing in the
Enguri hydropower station, the country’s main power source. It has been a long
and torturous road and the job isn’t finished yet, but residents can now flick
on their light switches in Tbilisi at any time of day and find the electricity
is working. Improvements at Enguri will help Georgia to reduce imports of
expensive natural gas used for power generation and improve security of supply
by replacing it with renewable domestic hydropower.
Geopolitical power play
Enguri was built in 1978 to provide peak electricity to the then Soviet Union.
By the time the Soviet Union disintegrated in 1991, the plant urgently needed
rehabilitation following years of zero maintenance. The plant’s unit three
shut down completely in 1993, robbing the country of 10 per cent of its power
supply; other units operated below capacity.
Rehabilitation seemed impossible. The state argued it had no funds. And the
plant straddles a disputed internal frontier with Abkhazia, a territory that
has long fought for independence from Georgia.
Merab Daritaia is the Chief Engineer of Sakhydroenergomsteri, the state
company that built the hydropower plant. He was just 22 years old when he
moved to Sokhumi city – in what is now the Abkhazian-controlled zone – to
build the Enguri power house.
He remembers that 21,000 people were employed to build the plant. “There I met
my wife,” says Mr Daritaia. In Sokhumi, his son, Temur, was born.
The plant became his life. He has spent 25 years in the settlement. The memory
of watching it decay brings tears to the eyes of a now grey-haired Mr Daritaia.
In 1998, the EBRD agreed to lend the Georgian government $38.75 million to
rehabilitate Enguri; the EC offered a grant of €9.4 million. “This was a brave
decision as the plant was in a conflict zone,” says Mr Daritaia.
The project floundered for a number of years for many reasons including the
Abkhazia conflict and difficulties in tendering the project contracts in
accordance with EBRD’s stringent anti-corruption procurement rules.
At last, Georgian technicians were allowed to enter Abkhazia to repair the
power house; in return, the Abkhazians would receive free energy.
Towards the power house
Driving towards the power house, Mr Daritaia feels uncomfortable going through
an unofficial checkpoint manned by young Abkhazians. “There have been times
when our workers have been kept at gunpoint,” he says, “but I believe that the
rehabilitation helped to build a working relationship with the Abkhazians.”
In March 2006, armed guards from elsewhere in the Commonwealth of Independent
States were brought to guard the plant on the Abkhazian side. One of them,
aged 23, comments that “guards like me are essential to safeguard peace and
normal life.”
In the power house, all the equipment is new and carries English rather than
Russian trademarks. “Three out of five energy generating units have been
restored thanks to the EBRD loan and together they now produce enough to
supply a quarter of the country’s needs,” says Malkhaz Tskvitishvili, the
Project Manager.
He leads the way into the galleries within the 271-metre-high dam, the world’s
highest arch dam, and discusses with Laurent Chabrier, the EBRD banker
involved in Enguri, how this loan has changed the plant.
The plant was shut down completely in March 2006 so that rehabilitation could
start. Beneath the dam reservoir is a series of huge galleries, one atop the
other, containing equipment essential to plant operations. “About 5.3
kilometres of galleries were rehabilitated,” says Mr Tskvitishvili. “They were
flooded in water.”
The pressure gallery, 100 metres under the water reservoirs and the riskiest
point of the dam site, was rehabilitated. So were the valve chamber, the
pressure tunnel and the equipment to monitor geophysical movement that could
weaken the dam.
A safer, more dependable dam
“It is now safer to work in the plant,” observes Mr Chabrier. “This project
has improved safety in terms of the dam, the workers and the region. Above
all, it has brought reliable electricity to Georgia.”
And that is not all. About 140 staff were trained thanks to a Swiss government
grant, a road linking the power house with the dam was rebuilt and the
workers’ settlements were refurbished in Potskho, the ‘village of the dam’.
Five hundred people live there, of whom 300 are rehabilitating the dam.
Jimi Akubardia, one of them, disappears inside the dam every morning at 7am.
He is too busy cleaning and dismantling equipment to have time for talk. His
parents and grandparents depend on his $380 per month salary.
No power cuts in Tbilisi
“The three power units came back on stream on 14 July 2006,” says Mr
Tskvitishvili. The EBRD is now considering extending the loan to cover
rehabilitation of the remaining two energy generating units.
“The Enguri hydropower plant is essential to Georgia. It covers 40 per cent of
Georgia’s total energy consumption. The state was not strong enough alone to
rehabilitate this plant,” says Archil Mamatelashvili, Deputy Minister of
Energy. “We needed the EBRD and the EC to raise finance.”
Much has changed since the blackout days. A former Minister of Energy is now
in prison, charged with corruption. And the power company will be able to fund
its own maintenance programme: 70 per cent of customers now pay for
electricity compared to only 30 per cent in 2002.
“Drive around the Georgian capital, Tbilisi, in the evening and you feel you
are in a city as brightly lit as Las Vegas,” says Malkhaz Tskvitishvili.
