HIGHLIGHT – In Belgium, three nuclear reactors have
been stopped and thus may jeopardize power supply in upcoming winter. An
interesting case observed with attention in France, where power shortage may
happen as soon as winter 2015.
To know if you will get light this winter, please click here.
In
Brussels in early September, the Interior minister published a wide map of the
country allowing people to see if they may experience power shortage during
winter, town by town and even street by street. The reason of this situation
lies in the stop of two on seven Belgian nuclear reactors, Doel 3 and Tihange 2
namely, since spring, because of the presence of micro-cracks in their tanks. Electrabel,
GDF Suez’ subsidiary, has been operating these facilities since thirty two
years. But also there has been a third reactor out of power, Doel 4, following
a mysterious sabotage, this summer. For an overall 20,600 megawatts (MW) of
power production capacity (among which 4,400 coming from solar and wind), 3,200
are unavailable, thus rising the risk of a power shortage on a wide scale for
next winter.
Elia, the manager of the power transport network, has calculated the
risk very precisely: it would
amount to 49 up to 116 interruption hours, depending on winter
temperatures, thus corresponding to a possible few daily hours of load-shedding
during several ten or so days for a significant part of the Belgian population.
Suddenly, everybody has become aware of the extent our lives depend from power:
thus what would happen for trains circulation, money withdrawals, winding up
shutters, cows milking or freezer unfreezing?
Cutting supply
Chaussée of Waterloo, in the middle of the Uccle quartier, in Brussels
chic surburb, the manager of Jaco’s brasserie heard of the risk of power cut-off
in the local press. But Théo Athanas became really aware of it when he received
the visit of a generators dealer, who offered him an equipment of … € 20,000 to
enable him to make his lunchtime and dinner services without any power
shortage. His small business would be badly hit by load-sheddings, which would
take place during peak load periods, namely between 5 and 8 pm and between
11,30 am to 1pm. “I have fifteen
employees and I can’t wait the end of power cut-off to start the service!”,
sighs the manager. His power supplier, Electrabel, sent him to his power
distributor, namely Sibelga. “That’s the
politics of fait accompli, whereas we pay quite a large amount for gas and power”,
he fulminated: a monthly € 4,000.
If
Théo Athanas is affected by possible power cut-offs, it’s because of an history
meander:in
order to limit disruption, Belgian towns counting more than 50,000 inhabitants
won’t experience load-shedding, and particularly the 19 towns composing
Brussels-Capital, save this Uccle quartier
of several thousands of power meters, known of every local French as it
shelters the Jean-Monnet French secondary school.This part of the town is supplied by a high
voltage post located out of Brussels area, and thus, composing a part of the
plan of power cut-off. That’s impossible to escape it by arguing about the
location in Brussels or raising the issue of population density: the operator
shall cut power supply from a high voltage post, or a “cabine” in Belgian
officialese, supplying a large area. In Uccle, the avenue where there is the
French secondary school and its adjacent streets may be in black in case of peak
load.
Foreseeing problems
The country has been
break down in five zones, each one being break down in six parts: The operator
of the network will cut-off power a first part of each zone during several
hours, amounting thus to 500 MW of power, then a second one if it’s not enough,
and so on. Zones will change from one day to another, to break down efforts. the shortage in order to avoid the collapse of the network – the black-out –which would entail
consequences going far beyond Belgian borders and which would be really long to
be tackled with. Moreover, the crisis has sparked dissensions between the
Flemish and Walloons, as they accused each other to be privileged in case of
power shortage….
All the economic partners have been involved to anticipate problems,
from the Belgian National Bank, to Comeos, the Belgian distribution federation,
which is responsible to control the cold chain integrity by supermarkets. In
case of programmed power cut-off, inhabitants will be warned 24h in advance by
radio and television, and a leaflet will be distributed in the streets affected
by this shortage. The public authorities are now making recommendations: don’t
open the frigo for nothing, make everything cook in a single pall, and use
preferably SMS to communicate. Elia is concerned that, in case consumer are
warned of an imminent shortage, they reload their devices during the preceding
hours at maximum, thus catching the network unawares…
For other sectors, Sibelga, the Brussels distributor, warned that people
must prepare themselves. “If you need
power for your health, please use the emergency services calling 112”, it
points. And “if your company’s management
is threatened by a power cut-off, you’ll do better in implementing a
second-hand solution at any moment”. “In normal conditions, a power shortage
may always happen”, says the operator.
“ Imbalance tariffs”
From the side of power production, Elia has yet mobilized all the
available resources to minimize a possible power cut-off. A tender has been
launched to constitute “a strategic
reserve”, composed of two gas power plants which announced their closure, namely
Vilvorde, owned by Germany’s E. ON, and Saraing, owned by EDF Luminus. Some
major industrials accounts have accepted to postpone their consumption in case
of need, with a cash compensation. All these measures will add 850 MW of
production capacity. Moreover Electrabel has divided the duration of the
maintenance of Tihange 1 reactor, to make it available this winter.
Belgium, which is located in the core of the European grid and which is
a structurally power importer (whose two thirds came from France last year),
has thus requested the help of its neighbors. But there are technical limits: the
number and the size of the very high voltage lines between Belgium and its
neighburs, namely limited to 3,500MG of import capacity at best. As each power
supplier is responsible of its customers’ supply, the kilowatt/hour on the
wholesale market may experience a sharp increase during highly tensed periods.
“ The market partners shall pay an imbalance
tariffs set at €4,500/megawatt/hour ( thus around 100 times the normal tariff,
author’s note), for each megawatt/hour consumed by their clients which would
not have been produced, imported or avoided thank to the flexible management of
the demand in their portfolios”’, warned Elia.
The worst may not happen. It would heavily depend on the weather, which
has been fair so far, whereas the government hopes that Doel 4 will be brought
in line again in January. This episode may have some positive effects. First,
consumers are more aware about the need of moderation. On November, 3rd,
Elia launched its “power indicator”: green,
orange, red or black. This indicator shall be presented daily at the
television, to warn about the tension or the need to control one’s consumption,
or not. Perex, the circulation centre
for Walloon area, has also been requested to study a possible extinction of a
part of highway. Then Coreso, which groups several European networks operators,
will make some experiments, such as circulate more power, at a given
temperature, on some lines, “to see if it comes through”. Thus it
will be possible to maximize trans-border exchanges.
Facing the same problem elsewhere
Neighbouring countries are observing the Belgian case with much
interest. That’s a natural experience for France, whereas RTE, the transport
network operator, has announced that winter 2015-2016, and above all, the next
one, will be tense in case of very cold winter. “The Belgium situation is the example we find almost everywhere in
Europe”. And everybody starts to ask
the relevant questions in the relevant sense. Now, it’s high time to get the
relevant answers”, said Stéphane Brimont deputy CEO of GDF Suez
European energy branch. In 2012, Electrabel, its subsidiary, has already
closed two gas power plants, with a kind of arm-wrestle with the authorities
about an insufficient profitability of production means, whereas the drop of
price market has freezed new investments for all operators. “ We were pressed to make the most possible
interconnexions instead of being able to maintain our own production
capacities. But that’s a kind of
illusion: if France faces shortages, we may open the taps, nothing will flow”, highlights Luc Hujoel, Sibelga CEO. “Intuitively,
I am less concerned than the Belgian government, since the country is well
interconnected with powerful neighbors. But the Belgian situation illustrates heavily
the use of the capacity market”, said Dominique Maillard, president of
RTE’s Supervisory Board . Instead of strategic reserves and of tenders
for new production means, France through RTE will “build a capacity mechanism”, intending thus to provide supply
security.
A possible power shortage in Belgium already modifies the power
balances. Some Belgian towns have signed a peace agreement with Elia to end the
judicial cases which were blocking projects to modernize the network. That’s
the case of Bruges or Maldegem, where a 380,000 volt line shall be built
between Zeebrugge and Zomergem. According to Elia,a “compromise” has been drafted to “improve the landscape integration” of the new line. In addition, a new tender has
been issued to build a new power plant.
Following a government change and the arrival to a more nuke-friendly
coalition to power last month, the choice of a progressive coming out of
nuclear made in 2012 is also questioned. The Doel 1 and Doel 2 reactors (each one
producing 450 MW), which should have closed definitely in 2015 after forty
years of operations, may thus benefit from a ten years operating extension, if
the State and GDF Suez find an agreement about their profitability.
