Consistent service: Tarbela Dam The gush of waters from the Himalayan glaciers to the low gradient Arabian Sea provide this part of the region with the unique opportunity to exploit a mammoth source of potential energy. In its early history, Pakistan managed to harness hydro potential and then depended heavily on that in the decades to come.
Completed in 1967 as a consequence of the Sindh Water Treaty, Mangla Dam was the first big step towards converting this opportunity into strength. The multipurpose reservoir had been built on River Jhelum, within the jurisdiction of Azad Jammu and Kashmir (AJ&K) with an installed power producing capacity of 1,000 MW.
Subsequently, Tarbela Dam had been constructed on the waters of the mighty Indus in Haripur District at the periphery of Khyber Pakhtunkhwa. The project started functioning in 1976; four tunnels had been carved out and fitted with generators with an installed capacity of 3,478 MW.
Mangla Dam is the ninth largest, while Tarbela is the largest earth-filled dam and the second largest overall in the world. It was a huge accomplishment; arguably the most significant infrastructure development to-date in our post-colonial heritage. This duo of dams has been a saviour for Pakistan’s energy needs, without whom the present day crisis would have been infinitely worse..
Afterwards, the only major contribution came in the shape of Ghazi-Barotha Hydropower Project, a run-of-the-river hydropower facility developed in 2002, again on the River Indus, but this time within the precincts of Punjab, near the town of Attock. The installed capacity of Ghazi Barotha is 1,450 MW.
With these three, our history of developing mega hydro projects ends and the sorry tale of political controversies, administrative ineptness and lack of politico-economic vision starts.
Although hydropower plants are considered to produce the cheapest electricity units, they are also the most capital intensive. For a country like Pakistan, it is not possible to undertake such big projects without the financial support of international development agencies — a fact which brings in its own share of peculiarities and challenges. The envisioning and abandoning of Kalabagh Dam, with the proposed installed capacity of 3,600 MW, exposed the underlying dissonances within our power-sharing structure and provided small provinces the chance to express their grievances about the allocation of resources.
On the upstream, the polity around KPK, regardless of their affiliations, had been anxious about the submerging of their cities as a consequence of building the dam. The huge outstanding amount due on the federal exchequer on account of Tarbela royalties also added to their scepticism.
In the downstream, the people of Sindh felt their consent was not being taken in the matter nor were apprehensions of the potential desertification of their lands being allayed. The bitterness reached such levels that some pro-Kalabagh dam elements did not shy from dubbing the challengers as traitors. In Sindh, meanwhile, the nationalists went so far as to advise masses that their water may become infertile because its ‘power’ would have already been drawn during the process of electricity generation! The result was that Kalabagh remains a non-starter.
Despite the noise, there has been consensus among stakeholders that hydro power is the most important tool for Pakistan to achieve a sustainable energy future. Since no fuel is needed as such, the variable cost of production remains significantly on the lower side when compared to other sources, and therefore acts as a shock absorber to keep burgeoning consumer bills in control.
This is probably also one of the reasons why Pakistan enjoys the highest electricity penetration in the region: 93.6pc as compared to 88.7pc in Sri Lanka, 78.7pc in India, 76.3pc in Nepal, and 59.6pc in Bangladesh.
All of Pakistan’s hydropower projects, with an installed capacity of 6,720 MW, are understandably located in upcountry: 3,849 in Khyber Pakhtunkhwa, 1,699 in Punjab, 1,039 in AJ&K, and 133 in Gilgit-Baltistan. The hydel electricity pie in Pakistan’s total power generation capacity is around 30pc, which is pretty impressive and almost double the world’s average. If the untapped potential could be harnessed, this share can be improved further, or at least, should be maintained for decades to come.
Although hydropower plants are considered to produce the cheapest electricity units, they are also the most capital intensive. For a country like Pakistan, it is not possible to undertake such big projects without the financial support of international development agencies — a fact which brings in its own share of peculiarities and challenges. The other major challenge in the successful implementation of hydro projects is the (lack of) cohesion within various official entities involved — federal and provincial ministries, Nepra, Wapda, PPIB, etc. — which often find themselves trying to achieve conflicting goals.
The Neelum-Jhelum Hydropower Plant — 969 MW; Tarbela Extension IV — 1,410 MW; Tarbela Extension V — 1,320 MW; and Karot Hydropower Project — 720 MW are some of the mega projects which are already into the implementation phase and should be completed within the next two to three years. If not, the PML-N will find itself in the deepest of waters in the next general elections scheduled in 2018. In addition, Diamer-Bhasha Dam — 4,500 MW; Dasu Dam — 4,320 MW; and Kohala Hydropower Project — 1,100 MW are in the early completion phase and need policy continuation to be completed within the stipulated timeframe.
Oil
Source: Pakistan Economic Survey 2013-14 Unlike hydropower and indigenous natural gas, oil is our major handicap as it is mostly imported both in the shape of crude oil and finished petroleum products. In 2014-15, Pakistan imported $11.7 billion worth of petroleum which accounted for around a quarter of country’s total trade bill.
Among key petroleum products, which are produced by refining the crude oil, diesel is mainly used for mass transportation and to run tube-wells, petrol is primarily used as auto fuel, and furnace oil is chiefly consumed in power plants. In the past, High Speed Diesel (HSD) — or simply diesel — enjoyed budgetary subsidies which were taken off gradually to make way for an open market regime. With the arrival of CNG, petrol — which is called Motor Gasoline in the industry jargon — witnessed subdued demand growth for a brief period before bouncing back as a result of robust growth in the automobile sales and CNG shortages.
It is furnace oil — or fuel oil (FO) — which needs special mention in the context of Pakistan’s energy landscape. The use of furnace oil substantially increased in our later history due to the propping up of thermal power plants at the turn of the century.
Installing an FO-based power plant is arguably the most tested, cheapest, and quickest methods of producing electricity in mass quantities. Also, furnace oil is considered cheaper as it usually sells at a ‘discount’, rather than at a ‘premium’ as in the case of diesel and petrol, over its input, i.e. crude.
In addition to the setting-up of thermal power projects under the traditional WAPDA establishment, the concept of Independent Power Plants (IPPs) also arrived in Pakistan in the ’90s with all its accomplishments and controversies. On the one hand, the successful implementation of the public-private venture of that magnitude — with salient features like two-part tariff, non-recourse project financing, sovereign guarantee, etc — was touted as a success story by the international developmental agencies.
Lately, local production of condensate — a lighter mixture of hydrocarbons which can be refined to produce petroleum products — gained momentum and together with the crude oil surpassed the level of 100,000 barrels per day (bpd) as compared to around 67,000 in 2012.
On the flip side, dealings with IPPs took centre stage in the power show between PPP and PML-N during that era. Shouts of kickbacks also resonated till the mess was finally settled with the help of international arbitrage. Amidst that ruckus, the fact that the country had been exposed to a tremendous and an unprecedented financial risk, and needed an adequate cover, was downplayed by the policy makers and implementers.
After an extended period of sluggishness, international oil prices rose unabatedly during 2002 to 2008, witnessing around a fivefold increase. Consequently, price of furnace oil (FO) in Pakistan also showed an increasing trend which disturbed our energy equation.
The impact was so strong that even the military backed and financially shrewd administration of Shaukat Aziz could not pass the increase in power generation cost to consumers. Budgetary subsidies to cater for the difference in the cost and the consumer tariff were not enough either and got busted shortly. The FO experience was so bitter that even the word became an unwanted mention around the ‘power’ corridors and thus the subsequent new ventures were put on the backburner.
Lately, local production of condensate — a lighter mixture of hydrocarbons which can be refined to produce petroleum products — gained momentum and together with the crude oil surpassed the level of 100,000 barrels per day (bpd) as compared to around 67,000 in 2012.
Although the quantity is not enough to suggest that we can get rid of the imports, however, it can still narrow down some of our energy gap in addition to saving the foreign currency.
The present lack of local refining capacity to cater for the locally produced hydrocarbons is a challenge which needs to be overcome to capitalise fully on this development.
The recent decline in oil prices caused a substantial decrease in the cost of furnace oil which in turn brought down the average per unit cost of electricity. In the short run, consumers will benefit from lower bills, power sector will benefit from improved capacity utilisation, and the government will get a respite from the monstrous circular debt. To find a long-term and a sustainable solution, lessons learned from the last episode must be taken into account.
Almost all of our oil imports come from the single source, i.e. Middle East, which was further narrowed down after we stopped buying the commodity from the neighbouring Iran post sanctions.
Here, it would be interesting to note that Indo-Persian oil trade continued, on deferred payments, during the same period while we don’t even look prepared to cash in from the possible reopening of the Iranian market. Without denying that we enjoyed favourable terms from friendly suppliers in the past, diversification of the supply base shall be considered for a sustainable future.
The low oil price scenario presents an opportunity to find a sustainable energy solution. This has to be done with a sense of urgency because with the present energy mix the country is still exposed to the upside risks of the international oil prices.
