As per IGCEP, current installed capacity (December 2019) is 35,344 MW while derated capacity is 32,240 MW. IGCEP Table B-1 has some calculation errors as shown in figure below.
After rectification of these errors, total installed capacity of the country stands at 34,668 MW out of which 58.96% belongs to private sector projects and 41.04% is owned by public sector. There are no calculation mistakes in derated capacity as presented in Table B-1 of the IGCEP.
Public Sector Projects:
Public sector projects are maintained & operated by four major organisations of country i.e. Genco-I, Genco-II, Genco-III and Wapda (responsible for public sector hydropower development in the country).
Public Sector projects have cumulative installed capacity of 14,228 MW out of which approximately 66% i.e. 9,389 MW are hydel projects. Majority of hydropower share in the total installed capacity of the country is due to public sector hydropower projects. It is interesting to note that Tarbela Dam and its extension (04) weighs more than 52% of total hydel capacity and ~34% of the total installed capacity of public sector.
Public sector projects operate mostly on furnace oil, gas, RLNG and hydropower. Following table demonstrates the proportions of different fuel sources used for installed capacity of public sector projects.
Private Sector Projects:
Private sector contributes 20,439 MW i.e. 59% of total installed capacity in the country. Although private sector contributes through both renewable and non-renewable generation technologies, majority of installed capacity (more than 82%) in private sector is still thermal based.
First private sector hydropower policy was introduced in year 1995, however this is unfortunate that during last 26 years only 522 MW i.e. 2.55% of total private sector projects could be implemented. During the same time thermal power projects were promoted to such an extent that today they weigh more than 80% of all installed capacity in private sector.
Renewable technologies like wind and solar have shown considerable improvement during the last couple of years and their cumulative share in the total installed capacity of private sector have risen above 7.25%. IGCEP has emphasised the development of these technologies targeting their share in total installed capacity of the country between 20% & 30% during next decade. However its also important to consider the intermittent nature of energy generation by these technologies.
