Industry review (Power sector)
The Power Sector of Pakistan comes under the ambit of Ministry of Water and Power, which is mainly responsible for formulating Pakistani Energy Policy and to ensure that the country’s energy needs are met. The constituent entities involved in the regulation and supervision of the sector include NEPRA, PEPCO, PPIB, AEDB, PAEC and the Provincial / AJK I&P departments. All of these entities are working under the umbrella of the Ministry, and each has been designated a specific role. Apart from the entities identified, the Power Sector also constitutes of certain power generation entities, such as WAPDA, GENCOs, Nuclear Power Plants and IPPs and other entities which are involved in the transmission and distribution of electricity across Pakistan, and include NTDC, KESC and the DISCOs. A graphical depiction of the overall structure of the power sector has been provided in the following illustration.
Current Installed capacity (will update it later on and compare it with 2017 report)
Installed power generation capacity of Pakistan as of 30th June, 2017 stands at 28,399 MW of which 26,186 MW is connected with NTDC system whereas 2,213 MW is connected with K-Electric Limited (KEL) system. Since 2013 till date, more than 7,000 MW has been added to the generation facilities connected to NTDC system. Based on recent information by NTDC, and analysis by NEPRA, generation capacity additions in NTDC system over a period up to the FY 2024-25 are as shown in the following table. However, the final installed capacity of more than 62,000 MW may not be achieved timely as some of the power projects including hydro-based projects indicated to be inducted from 2022 to 2025 requires extensive technical and financial prerequisites to commence operation.
Generation capacity and demand:
The generation capability of generation facilities connected with NTDC system will be less than the installed capacity as shown in the above table due to various factors like auxiliary consumption, impact of site reference conditions and seasonality effects on the renewables and large hydropower plants. The generation capability is effectively the capacity for meeting the electricity demand in NTDC system. The data about generation capability and future demand as reported by NTDC is shown in the following table.
Capacity mix:
The Government of Pakistan has been pursuing broad objectives for the power generation development including, renewable energy, moving to environmental friendly fuels and reduced dependence on imported fuels. Also diversification of fuel resources and security of fuel supply were among its priorities. The addition of different new generation technologies shown above will change the power mix of the sector from Furnace Oil-based to Coal, RLNG and Renewables as no major addition has been planned on Furnace Oil. The following table shows changes in installed capacity mix over three representative periods.
Clear trends may be noted in respect of different fuels. In the FY 2016-17 about 9,000 MW is based on Gas/RLNG, which will increase to 12,626 MW by the FY 2020-21, however no further addition is foreseen till the FY 2024-25. Oil based power generation plants have not been planned throughout the period and share of oil based generation capacity declines from 25.91% in the FY 2016-17 to 10.91% in the FY 2024-25. Share of coal-based generation increases from 3.09% in the FY 2016- 17 to 19.56% in the FY 2024-25 mainly on Thar Coal based projects. Hydro-based generation capacity also increases from about 7,000 MW in the FY 2016-17 to 20,676 MW in the FY 2024-25 representing a share of more than 33% in the overall installed generation capacity.
Fuel consumption in Power sector:
The share of installed capacity of thermal power plants using oil, natural gas and coal to the total installed capacity in the country, during 2016-17, was about 63.40% while the electricity produced by the thermal power plants, during 2015-16, to the total electricity generated in the country during same period was about 64.57%. The statistics of different fuel used and their percentage share to the total fuel used for thermal electricity generation of the country from 2011-12 to 2015-16 are as follows:
IPP review:
The IPP is an entity, which is not a public utility, but that owns facilities to generate electric power for sale to utilities end users. The electricity market was opened to IPPs in 1990. Subsequently around 40 IPPs have been awarded tariff by NEPRA.
For several years afterwards, the IPP program remained stagnant, only to be revived as a huge power shortage hit the country in 2006-07. In a regional context, Pakistan offers a relatively sophisticated operational and regulatory framework for the IPPs.
Independent Power producers contribute significantly in electricity generation in Pakistan but unfortunately, IPPs are producing below capacity as a result of working capital shortage caused due to outstanding amount of receivables from PEPCO/NTDC.
Like most other countries, here, IPPs face single buyer market. Water and Power Development Authority is the key buyer of IPP power. IPPs negotiate a tariff with the regulatory authority, NEPRA, under a transparent competitive bidding process. Investors are generally insulated from underlying economic risks through tightly written, long-term PPAs with underlying take-or-pay contracts, supported by explicit government guarantees and credit enhancements.
The fundamental principle underlying the contractual framework is to limit, as far as possible, the risks borne by the Project Company. A fundamental assumption is that all parties abide by the terms of their contracts.
The IPP Electricity Tariff:
The tariff charged to WAPDA by IPPs is not a number, rather it is computed from a formula. The formula includes in it the components of the fixed and variable costs. The total tariff is the sum of the Capacity Purchase Price (CPP) which is the fixed component and the Energy Purchase Price (EPP) which is the variable cost.
The CPP comprises:
- Project Debt payments (inclusive of interest principal).
- Return on Equity (Real Rate of Return over the project life)
- Fixed element of the operating and maintenance cost.
- Insurance cost for the plant.
- Foreign Exchange Differential cost in order to cover FX variation during foreign loan payment.
The EPP comprises:
- Fuel Cost which is set by the Government and above the world oil prices by an amount of a surcharge.
- Variable element of the operating and maintenance cost.
The tariff paid also depends on the total hours purchased or the Installed capacity utilized.
The government has to pay CPP i.e fixed cost even if they don't purchase electricity from the IPP. This is one of the reasons of mounting revenue expense gap resulting in circular debt.
Issues prevalent in the Power Sector
The overall power sector can be classified into 3 categories namely (i) generation, (ii) transmission & distribution and (iii) collection.
Generation
- Poor energy mix (dependence on oil for electricity generation)
- Delay in receivables leading to reduction in generation of Independent Power Producers (“IPPs”) owing to lower ability to purchase fuel stock
Transmission & Distribution (“
T&D”)
- T&D losses due to obsolete infrastructure.
- Tariff subsidies/delay in capacity payments.
Collections
- Low collections due to pilferage/theft/law & order. In FY 2016-2017 the collection rate was 92.65% for all the DISCOS in the country. The collection rates vary significantly across geography.
Corrective Measures for resolution of prevalent issues:
- Aggressive Fuel price adjustment in the consumer tariff allowing for robust pricing and reduction in subsidies.
- Provision of new explorations licenses and induction of indigenous fuel in order to reduce dependence on imported fuel.
- Investment in small hydropower plants for long term sustainability.
- Floating of utility bonds for upgradation of transmission lines and grid infrastructure.
- Special focus by DISCOs on high loss feeders for reduction in revenue loss.
- Encouragement of capex in order to enhance local manufacturing of major equipment in generation, transmission and distribution sector (Hint Turbines e.t.c)
