ISLAMABAD: India may claim the world’s biggest blackout, but in Pakistan an endemic energy crisis blamed on years of mismanagement cripples the economy and makes millions of lives a daily misery.

Six weeks after the new prime minister in Islamabad promised the shortage would be his top priority, blackouts have reached a peak – reportedly up to 16 hours a day in urban areas and as much as 22 hours a day in the rural parts of the country.

But with political posturing becoming more acute as the weak coalition stutters towards general elections, there is no quick end in sight.

Unprecedented power failures blacked out over half of India for two days last week, affecting more than 600 million people when three national grids collapsed.

In Pakistan, however, shortages day in, day out highlight chronic underinvestment in infrastructure, long-term planning sacrificed to short-term expediency, lack of leadership, cronyism and corruption.

For ordinary people it is almost unbearable, particularly during the holy month of Ramazan when Muslims fast from dawn to dusk, coinciding this year with temperatures over 50 degrees Celsius.

Peak demand for electricity in the summer is around 18,000 megawatts, with a third of that coming from air-conditioning, but power companies only manage to supply 13,000 to 14,000 MW.

Angry protests and riots erupt every few days and the central bank has warned the energy shortages have effectively put a ceiling on economic growth.

The government’s Planning Commission says power cuts shaved three to four per cent off GDP in the financial year 2010-11, with industry bearing the brunt.

At the heart of the problem is so-called “circular debt”, which the commission says stood at $4.4 billion in 2011-12.

The dual effect of the government setting low electricity prices and customers failing to pay for it means state utilities lose money, and cannot pay private power generating companies, which in turn cannot pay the oil and gas suppliers, who cut off the supply.

“It’s a crisis of management, a crisis which has been born out of indecisiveness, born out of procrastination, not taking the decisions required at the right time,” said Shahid Sattar, the Planning Commission’s member for energy.

He dates the problem to the rule of military ruler Pervez Musharraf, when a massive boom in demand was not matched by investment in new power stations.

Raja Pervez Ashraf, burdened by corruption allegations from his time as water and energy minister but sworn in as prime minister on June 22 after the Supreme Court sacked his predecessor, promised to fix it.

In mid-July, a 12-billion-rupee ($127 million) bailout led to a noticeable let-up in the blackouts, but since then cuts have been as bad as ever.

Opposition leaders have sought to make hay, with Punjab Chief Minister Shahbaz Sharif of the Pakistan Muslim League-N (PML-N) backing protests and complaining vociferously that his province is suffering an unfair share of the power cuts.

He has been photographed working in a tent, without fans or air-conditioning, as a gesture of solidarity with the sweltering masses.

With polls expected by April and rivalry fierce between the PPP and the PML-N, led by Sharif’s brother Nawaz, there is little appetite for cooperation even on what analysts agree is a “genuine national crisis”.

But neither is there a quick solution for whoever wins. The government needs to pay its bills, but the country also needs to generate more power.

Major projects such as the $12 billion Diamer Bhasha dam, which is expected to generate 4,500 MW, will not come online for another five or six years.

The rivers and valleys of the mountainous north may offer more than 50,000 MW of untapped hydroelectric potential, but Sattar says power generated from it could be unreliable and cannot guarantee year-round supply.

Coal reserves have been found in the Thar desert, but the quality is uncertain and international donors are unwilling to pump money into such an environmentally damaging form of energy.

The government is keen to develop nuclear power as it tries to wean itself off expensive imported hydrocarbons – the country spends 7.5 per cent of GDP on buying fuel, according to the Planning Commission.

There are currently three nuclear plants generating a total of 740 MW of power and there are plans to expand this to 8,800 MW, but only by 2030.

Saeed Alam Siddiqui from the Pakistan Atomic Energy Commission said two new reactors to be built by the end of 2017 would generate an extra 680 MW.

But as Pakistan is not party to the Nuclear Non-Proliferation Treaty it is excluded from trade in nuclear materials and technology, and can rely only on its neighbour China for help.

Parallel efforts to reform publicly-owned generating and distribution companies have met fierce resistance – an attempt to replace the CEOs of power companies last year ended in failure after industrial action.With Pakistan’s 180 million population growing rapidly and demand rising by around 1,500 MW every year, a daunting battle lies ahead.

If no solution is found and violent protests continue, political analyst Hasan Askari warns Pakistan’s ability to function as a state could be under threat. “If these people can challenge one government they can challenge any government,” he said. “Violence and agitation become the normal political style and you never have stability.”
