flagship power turbines

ISLAMABAD/SINGAPORE (Reuters) - General
Electric's flagship gas turbines ran into problems in Pakistan earlier
this year, leading to delays and lengthy outages at three newly built
power stations, according to several senior Pakistani officials and
power executives.
GE has said they were teething problems. But the questions over one of
its most important products suggest another setback for the company in a
year in which its shares have plunged and third-quarter results were
called "horrible" by new Chief Executive John Flannery. GE is now
undergoing major restructuring.
There is no evidence that GE's 9HA-Class turbines have fundamental
design flaws.
But so far the Pakistani plants, which began running this year, are
producing power at levels well below their capacity and the problem was
acute in the crucial summer months, when temperatures in the country
frequently exceed 40 degrees Celsius (104°F).
Data from Pakistan's Central Power Purchasing Agency, seen by Reuters,
showed the Bhikki, Haveli and Balloki plants jointly generated only a
half of their current maximum capacity in August.
A month later all three plants showed improved output but remained well
below capacity. Reuters was unable to review more recent data.
"It had terrible consequences because we lost a lot of power which would
have come to the grid during the peak summer," Yousaf Naseem Khokhar,
the top civil servant in the Energy Ministry's power division, told
Reuters. "It is now up to General Electric to rise to the challenge and
to take care of these issues... before next summer starts," he said.
In a statement sent to Reuters, GE said "every commercial HA site today
is demonstrating exceptional performance levels for both output and
efficiency". On the issues in Pakistan, GE said: "We've encountered and
communicated openly about launch challenges and readily resolved issues
during this time. It's important to note that challenges are common with
power plants of this size and complexity during the commissioning and
early operations phase."
GE also said in a separate statement that the three plants are expected
to deliver enough power to supply the equivalent of 7.3 million
Pakistani homes over their 30-plus-year life cycle, and that will make a
"meaningful difference in the everyday lives of the people of Pakistan."
The 9HA-class gas turbines, the GE power division's newest and most
prestigious product, entered the Guinness World Records last year for
efficiency, based on the amount of electricity generated from natural
gas at the power plant in Bouchain, France, where it was first put into
commercial operation in June last year.
Both the 9HA and the 7HA turbines - the A stands for air-cooled - are in
tough competition with similar products made by Germany's Siemens
<SIEGn.DE>, Japan's Mitsubishi Hitachi Power Systems - a joint venture
between Mitsubishi Heavy Industries <7011.T> and Hitachi <6501.T> - and
Italy's state-controlled Ansaldo Energia.
Flannery said in a GE investor presentation in November that "resolving
initial launch issues" with HA class gas turbines would be a future
priority.
TOUGH YEAR
GE's shares have fallen more than 40 percent this year, and the
125-year-old company announced this month it was cutting 12,000 jobs in
its power division, about a fifth of the workforce, to cut costs.
Operating profit of the power division, once the strongest part of GE's
operations, fell 51 percent in the third quarter against the year-ago
period. Flannery said the division, which brought in 28 percent of GE's
revenue last year, was "challenged" but could be turned around in one or
two years.
Pakistan, desperate for additional electricity to avoid crippling
blackouts, teamed up with GE to build the power stations at Bhikki,
Haveli and Balloki, all in the most populous province Punjab, at
breakneck speed.
GE won the contracts to supply Pakistan with six turbines for the three
power plants in 2015, based on the lowest priced deal per megawatt of
capacity.
The first problem was the deliveries were delayed by up to three months
and missed some of the summer months this year, several Pakistani
officials said. They said they were told the delays happened because a
part of the turbine needed further testing.
The plan was to fire up the turbines in simple cycle mode - delivering
around 800 MW per power plant - in the spring of 2017 and then to
upgrade to 1,200 MW combined cycle output after the summer.
The delays infuriated Islamabad, because getting additional power during
the summer was a crucial factor ahead of 2018 parliamentary elections.

One of the two turbines at the Bhikki power plant was delayed by
about a month. At the Balloki and Haveli plants, the turbines were
delayed by about three months, two senior Pakistani officials aware
of the situation said. Then, in early May, a combustion seal leak
was detected at one of the turbines at the Bhikki plant.
To fix this, and to apply the same remedy to the five other
turbines, GE airlifted all the units to France for repairs.
Pakistan's Prime Minister Shahid Khaqan Abbasi, who was then the
petroleum minister, told Reuters in July that GE spared no expense
to fix the problems. "They found the problem, they took out the
part, they went back to the vendor, they re-machined them, they came
back – all on dedicated transport flights," Abbasi said.
TURBINE DAMAGE
But that meant one Bhikki turbine was offline for about 40 days and
the other for about 50 days. The other two plants had not begun
operations at the time, but came online in July and August.
In a third setback, one of the turbines at the Haveli plant was
badly damaged during a power outage three weeks after it was
inaugurated in July, the Pakistani officials said.
At such times, batteries and a generator act as back-ups to ensure a
pump continues to push lube oil into the turbine.
"Both didn't work," said one of the Pakistani officials, adding the
diesel generator had no fuel. The turbine crashed, with damage
estimated at $33 million, and although it was refitted with a new
rotor by GE, it is still to resume operations.
The power station is being built by China's SEPCOIII Electric Power
Construction Corporation. SEPCOIII did not return queries for
comment.
"GE and SEPCOIII are working together to determine the cause behind
the loss of functionality of the planned backup power system," GE
said in a statement.
A senior Pakistani official in Islamabad said the delays and outages
had cast GE in a bad light.
"Frankly speaking, they have lost a lot of credibility here in the
government because of these plants," the official said.
In September, Pakistan awarded its most recent power contract to
Siemens, after bidding by several companies, including GE.
Stephen Tusa, an analyst at JPMorgan in New York, wrote in a recent
note that although GE has assured investors that the Pakistan
problems have been resolved, they could re-emerge in other plants
around the world.
"The risk is that if these issues are not remedied, GE has already
'sold' another around 30 units (around 10 plus of which are in
operation), some of which are at higher output ratings," he wrote.
"Remedies would have to be applied up the curve, something we view
as a challenge, especially as senior management tries to cut costs
aggressively. Stay tuned."
FORCED OUTAGES
Not everyone is complaining, even when performance isn't perfect.
In France, the Bouchain plant suffered 26 forced outages in the 15
months ending November, according to data published by operator
Electricite de France (EDF) <EDF.PA>.
Despite these unplanned outages, GE and operator EDF, with whom GE
has a long-standing alliance, say they are satisfied.
"The cause of these events varies, and in certain cases a single
event has been interpreted as multiple events. It would not be
accurate to link this number to HA technology as fewer than 10 of
these events were related to the gas turbine," GE and EDF said in a
joint statement.
In a another joint statement, the two said "the Bouchain facility is
an example of our HA technology at its very best". They added:
"During the commissioning and early operations phase, we encountered
minor issues that are very typical of what you'd expect with a
project of this size, but we worked together to quickly resolve
them."
