Surplus generation capacity, high fixed costs permanent source of high consumer-end power tariffs: Nepra report

ISLAMABAD: Ill-planned surplus generation capacity, low plant utilisation, high fixed costs and inefficient generation dispatch have become a permanent source of high consumer-end power tariffs, as well as a financial drain on the power sector and the federal budget, says the power regulator’s annual report.

The National Electric Power Regulatory Authority’s (Nepra) Annual Report on the Performance of Power Plants in Pakistan FY2024-25 said: “Overall, the [power] sector’s high fixed costs, low utilisation, and inefficient dispatch of generation resources collectively resulted in higher electricity tariffs and financial stress on the power system.”

It further said, “In summary, achieving an economically sustainable power sector requires thorough evaluation of the financial and economic consequences before adding new generation capacity. Simply expanding capacity without assessing its cost-effectiveness and expected utilisation can result in inefficiencies such as under-used assets and increased electricity costs for consumers.”

It added that a balanced strategy that considered long-term financial factors — including capacity purchase price (CPP), energy purchase price (EPP), and overall grid stability — was crucial to ensuring generation capacity matched actual demand, optimising the use of available resources and incorporating flexible solutions, such as renewable energy, alongside more cost-efficient technologies.

By carefully analysing the economic impact of each new capacity addition, the power sector could minimise unnecessary financial strain, improve efficiency, and help reduce electricity tariffs for consumers, the report said.

During FY2024-25, the overall utilisation of thermal power plants stood at 42.5 per cent of capacity while renewable energy plants operated at an average utilisation of 36.6pc.

“This underutilisation, coupled with excess installed capacity, led to a significant rise in per-unit electricity costs, primarily due to higher capacity payments”.

The total power purchase cost during the fiscal year — excluding electricity imported from Iran — was recorded at Rs2.943 trillion, of which 61pc comprised CPP and 39pc EPP. The per-unit CPP averaged Rs14.3/kWh and the EPP Rs9/kWh.

“The elevated CPP stemmed mainly........
