Transmission, distribution network not adequate to sustain new loads: Nepra

KARACHI: Power transmission and distribution networks are hardly adequate to meet the existing requirements and have little or no potential to absorb the planned generation, the regulator said.

“In view thereof, it is imperative that transmission and distribution systems may be strengthened and stabilized, besides completion of new transmission and distribution systems planned to transmit electricity generated by upcoming projects,” said the National Electric Power Regulatory Authority (Nepra) in its latest state of the industry report.

“Strengthening of existing transmission system requires large scale investment along with improved managerial performance by NTDC (National Transmission Despatch Company), in order to ensure availability of a reliable transmission system well before the completion of generation facilities,” the report said.

The Nepra said overloaded transmission and distribution networks not only hinder power transfer capability but also add to wastage of electricity through increased losses.

“The constraints on transmission networks have also led to severe power evacuation problems with the result that the capacities of some of the most efficient plants cannot be utilised to their optimum level,” it said. 

“In order to reduce losses, control theft and improve the service delivery to consumers and effective revenue recording, use of technology (smart meters, prepaid meters) may be immediately introduced in all distribution companies, while out-sourcing of inefficient service in distribution system may be explored and considered by the distribution companies.”

The regulator portrays a brighter outlook for the country’s power sector as federal and provincial governments have aligned their priorities for overcoming the energy crises.

“Government’s efforts for bringing new power generation plants through China-Pakistan Economic Corridor (CPEC) agreement reflects the realisation that the country is in dire need of energy resources to satisfy base load requirements,” it said.

Similarly, overall generation mix is also planned to have renewable energy projects, which will provide necessary diversification and increased energy security to the sector.

The introduction of re-gasified liquid natural gas (RLNG) projects is also a step towards adding relatively clean and cheaper energy generation resources.

The report said more than 17,200 MW are expected to be added to the system. In order to meet peak time demand, around 8,000 MW will be inducted by the end of June 2017.

“Although such a target by June, 2017 is quite ambitious this is achievable, as this planned capacity includes solar and wind Projects, 3,600MW RLNG-based projects, and under-construction hydropower projects at Tarbela and Neelum-Jhelum,” it said. “Sustained efforts are, however, required at all levels so that smooth and transparent implementation of these projects is achieved within the target dates.”

While it is satisfying to note that the generation sector has been drawing all the due attention, strengthening of the transmission and distribution sectors is equally critical.

The report said it is critical that timely completion of planned power generation projects, specifically through CPEC is ensured.

Infrastructure for coal transportation and RLNG are potential hotspots on which the operation of the mid country coal power plants and RLNG based power plants is dependent.

“In view thereof, it must be ensured that infrastructure for coal transportation and RLNG meet the timeline envisaged for respective projects,” it added.

Nepra said for the protection of environment from the emissions by coal power projects, the relevant agencies must adopt an aggressive monitoring regime before and during operation of such power plants.  —Javed Mirza
