Pakistan's solar boom leads to falling power demand

Pakistan's growing shift toward solar energy is emerging as a major challenge for the national electricity grid, with power demand and electricity sales declining significantly compared with last year. The trend is increasing pressure from capacity payments on consumers as distribution companies sell less electricity while fixed generation costs remain a burden on the system. According to the document, national electricity demand declined by 8.66% year-on-year, while electricity sales by various distribution companies (DISCOs) fell by around 10% during the April-June quarter. The decline in electricity purchases has increased the burden of capacity payments on consumers, as lower electricity sales mean fixed power-generation costs are spread across a smaller volume of electricity consumed. The shift of a large number of domestic and commercial consumers toward solar power has been identified as the main reason behind the decline in electricity demand. IESCO electricity sales drop by more than 10% The Islamabad-based distribution company, IESCO, recorded a 10.77% decline in electricity sales in April compared with the same month last year. Its electricity sales also declined by 3.55% in May and 6.29% in June compared with the corresponding months of the previous year. Overall, ISCO recorded a 16% decline in electricity demand during the April-June quarter, according to the document. Demand declines throughout quarter The document shows that electricity demand fell significantly in each month of the April-June period. In April, electricity demand was 16% lower than the same month last year. The decline stood at 8% in May and narrowed to 2% in June. The figures indicate that although the year-on-year gap became smaller toward June, electricity demand remained below last year's levels. Domestic consumers shift toward solar Domestic electricity purchases recorded a notable decline throughout the quarter. According to the document, household consumers purchased 19.69% less electricity in April, followed by declines of 7.92% in May and 5.72% in June compared with the corresponding periods last year. The figures highlight the growing impact of rooftop and other solar installations on conventional grid electricity consumption. Commercial electricity purchases also decline Commercial consumers also reduced their electricity purchases during the quarter. The document shows that commercial electricity consumption declined by 6.85% in April, 3.80% in May and 1.85% in June compared with the same months last year. The continued decline among both household and commercial consumers points to a broader shift away from grid-supplied electricity. The rapid adoption of solar power is changing Pakistan's electricity consumption pattern, particularly during periods when households and businesses can generate a significant portion of their own power. While the shift can reduce consumers' dependence on expensive grid electricity, declining sales create a financial challenge for the power sector because capacity payments and other fixed costs continue to be recovered from consumers.
