Power Sector Inside Out (Part-4)

Top Tens

In this section statistics are provided for projects which made their place in top and bottom tens. Major categories which were used to prepare these lists include Capacity, Generation and Capacity Factor. In every category 10 projects are selected which topped in their respective lists.

Installed Capacity:

Eight projects from top 10, have installed capacity in four figures. This group has cumulative capacity of 13,973 MW which is equivalent to 57.33% of total installed capacity of country. The remaining 78 projects in the country jointly represent both capacity and generation less than these 10 projects.

Collectively these ten projects generated 57,902 GWh, which make 54.58% of total generation made by all the projects during year 2013-14. These projects were able to utilize 47.42% of their nameplate capacity, however with a standard deviation of 13.54%.

Interestingly 70.01% of the capacity of this top ten list belongs to public sector summing up to 9,783 MW. They also generated 40,571 GWh i.e. 70.07% of the total generation of this group, utilizing 47.31% of their theoretical capacity. Out of these 7 projects, 4 are thermal power projects and three are hydel power projects. Thermal power projects have 3,855 MW of installed capacity making 15.82% of total installed capacity of the country and 27.59% of the total capacity of this group. However they could utilize only 37.03% of their nameplate capacity and generated 12,513 GWh during year, which is 11.85% of total generation of the country and 21.61% of total generation by projects in this group.

Hydropower projects in this list have total installed capacity of 5,929 MW, 24.32% of total installed capacity in the country and 42.42% of the cumulative capacity of the projects in this group. Tarbela Dam Hydropower Project is the largest project in the country with respect to both capacity and annual generation. It alone makes 14.27% of total installed capacity in the country and 14.38% of the total generation during year 2013-14. Together these 3 hydropower projects generated 28,058 GWh during year 2013-14 utilizing 53.99% of the theoretical capacity, which resulted their generation to be 26.58% of total generation in the country and 48.46% of the total generation of this group pf power plants.

Three projects from this list belong to private sector, two of them being the IPPs and one is owned and operated by K-Electric. Together these three projects have total installed capacity of 4,190 MW, making 17.19% of total installed capacity of the country and 29.99% of the total capacity of the projects which could make place in this group. These projects were able to achieve an average capacity factor of 47.19% and thus generated 17,331 GWh of energy during year 2013-14 which is equivalent to 16.42% of total generation of the country and 29.93% of the total generation of all the project in this group during the same year.

Annual Generation:

Installed capacity is good measure to understand the ability of a state to fulfil its energy needs, however what matters most is the energy generated by these power projects. As shown in Table 6 above, there are 14 projects (15.91% of total projects in country), with aggregate capacity of 636 MW did not produced a single kilowatt hour during the year. Therefore the actual champions of all the projects are the ones which contributed most to the generation quantities.

The projects in this group are mostly the same which topped the list of installed capacity, however couple of them could not meet the competition of annual generation and left their place for better ones. TPS Guddu (Units 1-4) and TPS Jamshoro could not meet the competition of power generation and were dropped out of this list. Uch Power and Bin Qasim TPS-II were unable to make their place in top ten list of installed capacity but made their place in this list proving being small in size never mean being small in performance.

Projects in this list have total installed capacity of 13,629 MW which is 55.91% of total installed capacity of the country, while together they generated 61,589 GWh, which is 58.34% of total generation of the country. Average capacity factor of all the projects in this group is 51.55% which is above than the average capacity factor of all the projects in the country.

Seven projects from the public sector topped the previous list, however only five could maintain their place in this list as well. All the three hydropower projects included in the previous group also made their place in this group as well. The combined capacity of these five projects remained 8,293 MW which is 34.02% of the total installed capacity of the country and 60.85% of total capacity of all the projects in this group. This quinary generated 36,305 MW which commensurate 34.39% of all the generation in the country and 58.95% of all the generation in this group during year 2013-14. The average capacity utilization factor of these public sector projects concluded as 49.94% which is almost equal to the average capacity factor of all the projects in the country.

From the remaining five projects in this list, three are IPPs with cumulative capacity of 3,516 MW, which correspond to 14.42% of total installed capacity of the country and 25.80% of the total capacity of all the projects in this group. These IPPs were able to generate 17,879 GWh during the year, which is 16.93% of total generation in the country and 29.03% of the total generation of all the projects in this group. These IPPs were able to utilize on average 58.01% of their theoretical capacity which is well above the average capacity factor of all the projects in country during year 2013-14.

K-electric own, operate and maintain 8 projects in total, but only 2 could make their place in this list.

Capacity Factor:

The true measure of the performance of any project is its ability to utilize its nameplate capacity. Projects can top both capacity and generation list but this performance criteria is entirely different and can prove a tough competition among projects. Big projects can generate more but small projects can be more efficient if capacity factor is used as criteria.

Same happened when we shortlisted the projects for this list. Only one project from the previous group could make its place in this list. There is not a single project which topped all three lists in our analysis. Eight projects could make place in first two groups but only one from the previous lists could become part of this final list.

Sadly none of public sector projects won the capacity factor top ten list. Total installed capacity of the projects in this group is 2,337 MW, which is 9.75% of the total installed capacity of the country, however they remarkably generated 17,222 GWh during the year which is 16.31% of the total generation of all the power projects during the same time. Average capacity factor of this group is 82.65% which is 167.27% higher than the average capacity factor of all the projects in the country.

Interestingly 9 projects which topped this list are thermal IPPs, while one nuclear power project also made its place on last number.
