plant is expected to be
auctioned shortly. These auctions are not property sales, but a transfer of operating rights for the next 30-49 years.
In privatization, new owners are expected to conduct fast and
reasonable rehabilitations to upgrade availability, achieve better efficiency, and meet EU
environmental emission standards in former public power plants, most of
which were neglected for a long time due to a lack of public funds. Most of them have low
availabilities, low
operation efficiencies, and are without environmental filters to meet the latest EU stack emission norms.
our political opinion may be against any
privatization, and you may prefer to operate the
plants under the public administration. But local legislation has fully and irreversibly been changed, hence there is almost no possibility of operating them under public
ownership due to no funds being available for
upgrades. It is a fact that energy investments are to be made via private funds
under private ownership investment, and
privatization was inevitable. We do not know in the end if this initiative will create
positive outcomes for the best interests of our
nation. Anyhow, we are energy professionals and we are to work in our business environment with the newly created
financial investment environment. These new investment opportunities should be considered in accordance with the new situation.
On the other hand, the Turkish Coal Board (TKI short) has local lignite mine fields but the Board has almost no budget or funds to build new
thermal power plants to operate and generate electricity. So the ruling government decided to initiate an auction for royalty transfer leasing tenders to operate the existing coalfields under private management for 30 to 49 years.
Earlier, the Adana Tufanbeyli coalfield royalty transfer leasing tender to build a 600
MWe thermal power plant for the long term (30
years) was completed. The winning price was 2.57
or 1.42 U.S. cents per kw-hr. Then, the Manisa
Soma Deniş coalfields for a 450 MWe thermal power plant construction was tendered. The final price was 4.69 Turkish kuruş
per kw-hour or 2.60 U.S. cents per kw-hr. Last but not least, the Bursa Keles coalfield for >270 MWe TPP has been completed. The last price was 5.61 Turkish kuruş per kw -hr or 3.11 U.S. cents per kw-hr. We expect that new tenders for operating the Konya Karapınar,
Eskişehir, and Tekirdağ Saray coalfields will follow.
It is a logical and
economical solution to lease the coal basin to an experienced private group under the condition that they build a thermal power plant nearby,
operate the coalfields, feed the thermal power plant with the nearby coal,
generate electricity, sell the electricity to the local market, earn money and pay rent to the Treasury per kw-hr sold. This is called a “long-term royalty transfer leasing” tender. It is rational, economical, and feasible, at least on the paper upfront. We do not know the outcome yet
since it has not been
enforced or implemented. We shall all see the
outcome later in time if all is true.
With some of our existing plants, the authorities decided to install the new power plant on the
coalfields in order to get close to the existing HV transmission lines and to avoid extra expenses. But they cannot exploit the coalfields underneath the thermal power plant. It is like a joke, but this is a reality in public
investments. So try to avoid any location on coalfields, choose a site nearby without coal mines underneath.
We expect that the new owners of the existing thermal power plants being privatized will have
new rehabilitation
programs to upgrade the plant availability, overall plant efficiency and
installations of the new and biggest electrostatic precipitators (ESPs) and flue-gas desulphurization (FGD) units to meet EU environmental norms. Currently, Soma-B
thermal power plant Units 1-2 have new bigger ESPs, but no FGDs. We expect
that the Seyitömer, Kangal and Soma thermal power plants will have new FGD units. New owners will have reasonable grace periods for investment in the installation of FGD units.
Now let us ask our
questions. If we were the investors, which thermal power plant should we buy? Which one is the best buy option? How much is
each worth? What is the expected payback period for each project?
We recall the recent
tender for royalty sales of the Formula One racing course. The winning group decided to turn down the order, since they felt that the project was not
feasible for reasonable payback and had made their earlier calculations incorrectly. They decided to cancel the tender, and leave the project. This is not acceptable. The
investor has no such luxury. Investors are to take their calculations seriously prior to tender participation. This is serious business. We talk about millions. It is
incorrect to act on the idea of “First let us get the
order no matter what the price is, then we shall find
a way to make a profit.” In a tender for the
privatization of an existing thermal power plant or royalty transfer of a coal basin for new thermal
power plant construction, there is no cancelation right for the winning party. There is no such luxury. You cannot say “Our estimations for an overburden on the coal stream is more than we expected, so we are
loosing money, there is no payback in the short term, so we want to turn over the contract and leave the project.” It is too late. However, there are such unacceptable instances in the local environment. We notice the price
escalation in tenders for the transfer of royalty in coalfields. Each new tender is higher than before. The last tender
price gives us an expected payback period of more than 10 years. That is not feasible. A project with a more than 10-year
payback period is not feasible. Simple bank accounts give you the
same return. Why are you wasting your time and
money?
estimation methodology of the price structure in a new power plant royalty transfer scheme or in the privatization of an existing thermal power plant. How can we figure out the
price? What payback is reasonable? Which one to choose?
First, there are some essential rules and assumptions prior to estimations. You should prepare “due diligence” reports. In order to prepare “due diligence” reports, you should visit the site (the plant site or the coalfields). Tender documents are not enough. Tender
documents do not clarify everything. There are many details at the site. The devil is in the details.
ou should spend time at the site with your project group. Not one day, maybe one week, or even one
month would be much better. The investors’
project development group should spend time at the site and speak with everyone, take notes, check and inspect every item, the equipment and machinery. The investors should hire experienced experts, preferably those who worked at the plant or
coal basin earlier.
Then your expected group should prepare a
pre-feasibility study to match the financial details,
availabilities, and assumptions of the decision-makers of the investment group, to finalize the feasibility prior to the declaration of the tender price.
In the sale of an existing plant tender, you take the rehab cost first. Your
group should calculate the unit coal price per kw-hr, before and after
rehabilitation. You should estimate the current and future O&M costs per kw-hr. You should calculate the expected personnel cost per kw-hr again. You should conduct
restructuring in personnel numbers for a better and more qualified workforce.
ou should estimate the electricity sales price for the available electricity markets.
In a royalty transfer tender, you should
consider completely new thermal power plant costs in unit kw-hr in lieu of the rehab cost above. Now you have the best availability and best efficiency, since the plant is new.
Now, we need to have assumptions for the
necessary financing. You develop a certain figure for the reasonable payback period of your money invested. Cash flow is important. We should keep in mind that in a coalfield utilization
scheme, we have at least a 4-5 year construction
period for a new thermal power plant, where we shall have no cash-in. On the other hand, in the privatization of the
existing thermal power plant, cash-in starts overnight. You get more since the plant is in
operation. However, the plant needs overhaul for higher availability, higher efficiency, and new
equipment to meet EU environmental norms.
That is rehabilitation. That needs interruptions in the operation. These rehab expenses are to be
calculated and taken into account in the price
structure.
In estimation of the
buying price of a thermal power plant, there are many methodologies. I will try to explain a
simple, easy method below. When the other
completed and presented for your final decision, please double check them with this method.
In our methodology, we need to calculate the
overall unit cost of the kw-hr we generate in our
plant. First, we need to calculate the share of coal costs in our unit kw-hr electricity generation. That figure could easily be calculated from the
MMBTU price of the coal available at the coal basin. Then we should calculate the unit costs of rehab expenses, Operation & maintenance (O&M), and unit personnel cost. Add up all these shares to find the final cost of kw-hr electricity generation. Then, we should assume a reasonable payback period for our investment in our environment. That is normally between 3-10 years. It is preferable for
periods to be close to 3 years, but not preferable if
more than 10-years. We should also estimate tax and the cost of business on our unit kw-hr. The
electricity price prevailing in the national markets for our expected payback
period should also be predicted. The difference between the predicted
electricity sale price and our final cost is our net profit per unit kw-hr. Then multiply the net profit by the annual plant availability, normally 6500 to 7500 hours per year, and average the
plant output capacity, which is to be calculated
from site statistics. Normally you will take over an existing plant at 6500 hours per year
availability, then conduct necessary rehab work to upgrade that figure to 7500-800 hours of
operation. The final figure is your annual net income. That figure is to be
multiplied by your
payback period, in order to come to your best tender price to quote.
In how many years do you expect to get your
investment back? It is between 3-10 years. If you
presume 3 years and declare a price based on that short payback period, your price could be too
low. You may loose the tender. If you presume a long payback period, you may receive the order but never get your investment back in that long period.
That is the investor
With that final price, will you be able to receive the
order? I do not know. That is why you are the
investor. Anyhow, you got the feeling of how much you should be spending
for a particular project. During open tendering, do pay close attention to your competitors. This is a real application of the “Game Theory” of John Nash, in practice. Some companies may increase their final prices for some irrational reasons, some do the same for some other rational reasons. You never know. All you have know is
where to stop and execute your game strategy
