A severe heat wave is currently affecting Bangladesh, with temperatures reaching previously unheard-of levels across the nation. The need for electricity to power cooling appliances like air conditioners and fans has increased as temperatures rise, significantly impacting the availability of electricity as well as the cost of these necessities.
Recent data reveals a sharp rise in electricity consumption amid the current heat wave. Compared to the same period last year, the Bangladesh Power Development Board (BPDB) reports a 20 per cent increase in power demand in rural areas and over 15 per cent in urban areas. The national grid is under tremendous strain due to this surge in demand, leading to frequent power outages and load shedding across different regions of the country. The primary reason for the increased power demand is the necessity for cooling solutions to combat the unbearable heat. To maintain bearable indoor temperatures, homes and businesses heavily rely on fans and air conditioners, especially in locations where temperatures can soar well beyond 40 degrees Celsius. However, supply constraints have exacerbated the situation, with demand for electricity exceeding the infrastructure's capacity.
Concurrently, cooling appliances have become significantly more expensive due to the surge in demand. Prices for fans and air conditioners have notably increased as retailers and suppliers capitalise on the heightened demand. Market sources indicate that compared to the same period last year, fan prices have risen by about 20-25 per cent, while the average price of air conditioners has increased by 10 to 15 per cent. The residents of Dhaka, experiencing particularly intense heat, bear the brunt of these price hikes.
Beyond inconvenience, the heat wave and ensuing electrical supply issues have significant implications. Prolonged exposure to high temperatures poses severe health risks, especially for the elderly, small children, and individuals with underlying medical conditions. Heat waves elevate the incidence of heat-related disorders such as heatstroke and dehydration, underscoring the urgent need for effective mitigation strategies.
To ensure the affordability of cooling equipment, targeted subsidies or assistance programmes for low-income households should be implemented. Additionally, the power grid should be strengthened to accommodate rising demand, and energy-efficient measures should be adopted to alleviate pressure on the system. Public awareness campaigns on heat-related health concerns and heat wave preparedness are also crucial in empowering communities to protect themselves during extreme weather conditions. Through proactive measures and a coordinated approach, Bangladesh can mitigate the adverse effects of heat waves on public health and electrical supply, safeguarding the well-being of its population in the face of extreme weather events.
