Pakistan’s energy system strained by surge in solarization, battery tech

ISLAMABAD: The rapid solarization and advancements in battery technology are increasingly challenging Pakistan’s existing energy system.

The influx of over 7,000 megawatts of imported capacity, coupled with some industrialists and bulk consumers installing in-house plants of up to 1.5 megawatts, threatens to disrupt long-term agreements with Independent Power Producers (IPPs).

This situation is exacerbated by mounting frustration among power consumers, who are being burdened with substantial multi-billion-rupee capacity charges on their monthly bills.

The provincial governments, especially Punjab and Sindh’s distribution of solar panels to the public, will further pressurise the system, as they will now be drawing less from the grid and so the burden of capacity charges will increase and ultimately the tariff, which will further take away consumers from the grid power.

“Various bulk consumers have done aggressive solarization, even they installed capacity of up to 1.5 megawatts and have kept the grid at backup,” Chairman Nepra Waseem Mukhtar said while presiding over a public hearing on Wednesday adding, “It’s [solarization] a threat.”

The Nepra chairman said that this 7,000 MW imported solar capacity is not for only rooftops, bulk consumers are also installing their big capacities. He also tasked the CPPA with conducting a study on solar energy usage, mapping and submitting a report to Nepra.

Central Power Purchasing Agency (CPPA) while pleading the case on behalf of Discos reported that electricity consumption in June 2024 was 10 percent lower than the reference period consumption, while two percent less than last year.

Waseem Mukhtar said that the government has launched a study to determine if Pakistan requires additional power generation capacity. He emphasized the need for a logical approach to adding more electricity to the national grid. The study is also evaluating that Commercial Operating Dates (CoDs) for some plants may be postponed, he said, mentioning that the study will determine which plants can be retired early.

Discos sought permission to charge an additional Rs2.63/unit from power consumers in their August bills on account of fuel charges adjustment (FCA) for June 2024. The authority, however, reserved its decision. Nepra member Rafiq Sheikh has criticised the inconsistency in solarization policies between the federal and Punjab governments. He noted that “provincial and federal governments are inconsistent with each other,” pointing out that Sindh and Punjab have begun distributing solar panels and Khyber Pakhtunkhwa is preparing for similar initiatives.

He also questioned Power Division officials about the wisdom of entering into long-term contracts if battery technology continues to improve. Sheikh remarked that the introduction of batteries and solar panels has significantly disrupted the system, highlighting that technological advancements are inevitable and cannot be stopped.
