techno- commercial analysis of importing coal for ultra mega power plant - 4000 mw
DESCRIPTION
Technical Paper Published at BEE, IndiaTRANSCRIPT
In this paper, a techno-commercial analysis method based on comparing 3 coal exporting countries in
Asia–Pacific region has been done for a 6 x 660 MW imported coal based ultra mega power plant
employing supercritical technology from Shanghai Electric Corp., China located in Krishnapatnam (A.P,
India) to show “How much economic is importing coal for Krishnapatnam UMPP ”. Annual coal
requirement is 15.33 MTPA @ 4290 Kcal/Kg (GCV) on GAR basis from Indonesia. FOB for Indonesian is
$ 50 /T & landed cost is $ 70.4 /T on CIF basis at plant site. Coal is imported in CAPESIZE vessels of
1, 75,000 DWT (87,500 GRT) @ 15 Knots in 7.5 days from Indonesia. KUMMP was awarded to
RELIANCE POWER LTD, & PPA of levelised tariff of Rs. 2.33/Kwhr has been signed between the
beneficiary state (T.N, A.P, Maharashtra & Karnataka) for 25 years. Analysis for cost formation of the
landed cost of imported coal at power plant site as well as the effects of coal consumption , cycle time
of vessels, different routes, duration & delivery time and characteristics of Indonesian coal has been
discussed. Indonesian coal is most economical because of short distance and huge availability to meet
plant requirement. Thus coal consumption is reduced by employing supercritical technology in KUMPP
as heat energy produced by imported coal is more efficiently utilised for generating electricity.
Ultr a Mega Power Plant 6 x 660 MW
umpp is located near krishnapatnam village in muttukur mandal of Nellore distt of coastal Andhra Pradesh.
LATITUDE 140 – 18’ – 26” N & LONGITUDE 800 – 07’ – 11.81” E. It has 6 units of 660 MW each which is to be
commissioned by 1st April 2013. The has installed capacity of 3960 MW. Contracted capacity is of 3465
MW to 3762 MW, employing supercritical technology from Shanghai Electric Grp,China. .
Some parameters to be considered for each unit :-
• Pressure: 247 kg/sq.cm (abs)
• Main steam temp :535 ° C
• Reheat temp : 565 ° C
• Station heat rate : 2250 Kcal / Kwhr
• Availability :90 %
• PLF : 85%
Project Dynamics
• The most suitable location for importing coal are south Africa, Australia & Indonesia in Asia- Pacific
region.
• 15.33 MPTA is annual coal requirement , 2076 tph ,49824 tpd @ 4290 Kcal/Kg (gcv) on GAR basis.
• Coal is imported on AR & DB basis .
a. AR (as received)- includes total moisture
b. DB (dry basis) - excludes all moisture
• Sharing of power- 40 % to A.P & 20 % to Maharashtra, T.N, Karnataka each.
• The nearest port to plant site is Krishnapatnam port.
a. One of the India’s largest and fastest growing seaports, Krishnapatnam Port.
b. It is fast becoming a port of choice for all international cargo originating from and destined to the
Southern and Central India.
c. Can store 0.63 MT (15 days) of coal at port and 1.26 MT at plant site for (30 days)
d. Maximum handling loss of 0.2 % at port.

Landed Cost of Indonesian coal
Landed cost consist = FOB ($ 50) + freight rates + inland handling charges at Krishnapatnam port.
= CIF + inland handling charges at Krishnapatnam
Data for calculating landed cost :
a) Cost of coal at Indonesian coal = Rs. 2000 @$ 50 /T ($ 1= Rs. 40)
b) quantity of coal imported form Indonesia through 175000 DWT vessel
c) rail distance (in km) for carrying coal from Indonesian Mine end to Indonesian Port
d) transportation cost of coal/tonne/km
e) coal handling charges /tonne at Indonesian Port
f) Sea - route Distance (in Km.)
g) transportation cost of coal/tonne/km
h) coal handling charges /tonne at Krishnapatnam Port
Options for sourcing coal
There are 3 options for sourcing coal:
a. Port > conveyer> project site
b. Mid sea Anchorage >
c. Mid sea anchorage >
Landed Cost of Indonesian coal
+ freight rates + inland handling charges at Krishnapatnam port.
handling charges at Krishnapatnam port = $ 70.4
Cost of coal at Indonesian coal = Rs. 2000 @$ 50 /T ($ 1= Rs. 40)
quantity of coal imported form Indonesia through 175000 DWT vessel = 87,500 T
distance (in km) for carrying coal from Indonesian Mine end to Indonesian Port
portation cost of coal/tonne/km= Rs.1 /Km
coal handling charges /tonne at Indonesian Port = Rs. 320
route Distance (in Km.) = 3667 Km
rtation cost of coal/tonne/km (through sea)= Rs. .30
coal handling charges /tonne at Krishnapatnam Port = Rs. 259
There are 3 options for sourcing coal:
conveyer> project site
id sea Anchorage > canal system > project site
Mid sea anchorage > captive port > conveyer > project site
+ freight rates + inland handling charges at Krishnapatnam port.
= 87,500 T
distance (in km) for carrying coal from Indonesian Mine end to Indonesian Port =100 Km
PDCA Cycle
• Plan : To procure best quality coal at cheaper rates
