Energy Efficiency Programme for Pakistan's Industry

PAKISTAN is suffering from the worst ever energy crisis that is adversely affecting almost all sectors of the economy, particularly the industrial sector.

The problem has been getting progressively worse throughout the year, with these pages reporting earlier how Pakistan’s government has been enforcing earlier closing times for offices and factories to try to conserve the energy they have from an under capacity generation system.

As the establishment of new projects for power generation will take some time, Pakistan’s Engineering Development Board (EDB) has embarked upon an energy efficiency and conservation programme in the industrial sector.

The problems can illustrated by the Pakistani steel sector, which is fragmented and plagued by old & obsolete technology, sub-standard products all very heavy energy wasters. The energy wastage in this sector, and much of the rest of Pakistan’s industry, are enormous and could be reduced considerably by taking some energy efficiency measures.

The EDB have arranged visits to some local re-rolling mills to point identify areas of energy wastages. It is then planned that these industrial units could be developed as pilot projects, which could then be replicated across the rest of the re-rolling sector of Pakistan.

The EDB is also looking at the furnace and melting industrial sectors to encourage installation of more energy efficient technologies.

The Pakistani melting-industry consumed 800 units of electricity in melting one ton of scrap, while the most efficient steel making technology available uses only 350-400 units of electricity to melt one tonne of scrap.

That calculates out to an energy wastage of about 400 units per ton. The estimated melting capacity in Pakistan is around four million tonnes, so this gives a staggering figure of about 1600 MW of wasted energy.

1600 MW is equivalent to one large hydroelectric power plant or a large power plant based on gas or fuel oil. It is expected that through this programme by EDB an enormous amount of electricity would be saved in just this industrial sector.
