Eskişehir Alpu Coal Fields and
1080 MWe New Thermal Power Plant,
to the MTA 2011 report (by İlker Şengüler) and Eskişehir Anadolu
University 2014 Academic Article (by Korhan Usta, Hatice Kutluk),
there are two horizontal local lignite coal layers extending
underground at depth from 250 to 450 meters in the Eskişehir-Alpu
coal basin in the southwest-northeast direction with layer
thicknesses range from 0.55 to 31.60 meters.
amount of proven reserves is about 1.5 billion metric tons. The upper
layer had an average ash content of 36%, sulfur content of 1.87%,
moisture content of 36% and an average lower calorific value of 1950
kcal / kg.
the lower horizontal layer, average ash content is 28%, sulfur
content is 1.13%, humidity is 32% and average lower calorific value
is 2150 kcal / kg.
is apparent that Eskisehir-Alpu lignite which is the third biggest
lignite basin of Turkey has very important economic value.
Alpu coal fields, currently belonging to Electricity Generation Inc.
(EUAS) were covered in the scope of new privatization. With the
provision of a 1080 MW power plant, the project will be handed over
to the private group which will give the lowest electricity sales
price in terms of UD cents per unit kw-hour.
to the news of the local Dünya (World) newspaper on 28 September
2017 (by reporter Mehmet Kara), the tenderers who will participate in
the tender by means of negotiations will compete with the commitment
to sell electricity to the EUAŞ at the lowest price. The
negotiation procedure shall be implemented by subtracting from the
initial sale price and shall be concluded by an open auction to be
made by the participation of the prequalified bidders whose bidding
negotiation is continued, if deemed necessary by the tender
deadline for qualification for the privatization of the Eskişehir
Alpu coalfields, with the condition of establishing a new 1080 MWe
thermal power plant and the transfer of operating rights, was set as
January 26, 2018.
coal deposits will be mined, 1080 MWe capacity thermal power plant
will be constructed nearby at mine mouth, coal will be enriched here,
then electricity will be produced, then will be sold to
national grid, and treasury will give a purchase guarantee. At the
privatization administration, the minimum sale price is expected to
be around 5-6 US cents / kWh.
Alpu Coal fields privatization tender required TL 25 million in
temporary bid bold for the interested parties for the transfer of
to the pre-investment project as developed by EÜAŞ earlier,
approximately 116.8 hectares of 1,125 hectares of coal production
area are planned, and about 30 hectares of coal stock areas are to be
allocated. The thermal power plant will be constructed within the
scope of the project with estimated value of US $ 1.8 billion. The
total installed capacity is 3 X 360 MWe and the thermal power is 900
X 3 MWt. As the main fuel is the local coal of Eskişehir Alpu
underground coal fields for the 1080 MWe Alpu Thermal Power Plant.
Approximately 6.3 million tons of domestic coal (lignite) will be
burned in the plant annually. When the plant goes into operation, a
total of 1 million 950 thousand tons of coal waste will be generated,
including 1.6 million tons of base ash and 350,000 tons of gypsum per
year. The new plant will be supplied with coal from sector B,
covering 1,787 hectares.
Turkey, with low calorific value of domestic coal, there are thermal
power plants with proven designs in long term operation, let us name
them. Soma-B # 5-6, Seyitömer # 4, Kangal # 3, Afşin-B.
are all very good at burning domestic coal, they all proved
themselves in 20-30 years long operation. They solved the problem of
domestic coal burning, but there may still be in need of new dust
filters, and new FGD desulfurization.
investors investing in domestic coal have not told us about the
results of their investments in China- Korea- Far East designs,
plants where most of them bought from Far Eastern companies. We do
not have details of their operations as explained in exhibitions in
panels at conferences. There are no success stories told. There are
no high efficiency, no high availability information. The leaked news
are not good. Once a project is realized, the project operation
results are generally shared with everyone in public.
is nothing publicly disclosed about CFB (circulating fluidized bed)
domestic coal investments in the last 10 years. There is a deep
silence in new plants with most of the domestic coal-burning CFB
technology. Nobody explains anything, on thermal power plant
operations where billions of dollars are invested. There is no news
made public, no information made available. Operation results are not
explained, information is not given.
explanation is as follows, we have very wet, almost 50-55% water
content- domestic coal containing moisture which can not be burned
properly without preheating, dehumidification, dewatering systems. In
extreme amounts, available wet lignite fuel can not be operated
without using high amount of supplementary fuel oil, which means
there is a hidden non-operation or failure problem.
plants have continuous failure in coal feed and ash/ slug removal
systems. Continuous rehabilitation is being done. The systems are
completely renewed. ESP Dust filters, FGD flue gas desulfurization
systems are not working properly, they are often shut down. However,
the plants still continue to work, and hence they pollute the
Eastern companies are proposing ready-made (off the shelf) CFB
designs, all-in-one solutions, with the cheapest financial packages
of their exim banks. Domestic investors, who are influenced by very
cheap prices, are convinced. China-Korea-Far East design CFB
technology are not suitable for our indigenous coal reserves. Senior
management decision makers who make this investment decision are
aware of the situation. They keep silent until they retire, they do
not make a sound.
thermal power plant, which will be located at a distance of 40 km
from the city center of Eskişehir, may become a real disaster for
the Eskisehir city if the environmental equipment would be
inadequate, if the project is not carried out under proper
international strict tender conditions, if the contractor firm is not
strictly regulated by international norms, standards, rules and
regulations. An uncontrolled project that has left at the mercy of a
Far Eastern contractor who will leave after 2-3 years from the
installation of the plant is wrong. The main contractor of this
project must be a competent local company that has been tested in the
past with proven past references at the same or higher output
