ISLAMABAD – The global power sector is facing big challenges. As more people rely on electricity for daily tasks, the demand for a stable power supply is growing. Since the Paris Agreement, power companies are working hard to meet climate goals and reduce emissions. This means they need to upgrade their infrastructure, especially to accommodate renewable energy sources.
However, extreme weather due to climate change raises concerns about the reliability of power grids. Events like dust storms, hurricanes, and floods can disrupt supply. The World Meteorological Organization announced that 2024 was the hottest year on record, pushing energy systems that were designed for cooler climates to their limits. According to the International Energy Agency, adapting energy systems to deal with these issues is a pressing concern.
In the US, power outages have become more frequent, with many lasting over seven hours. A lot of these outages are caused by severe weather events. For instance, areas in the Middle East and Balkan States faced blackouts during extreme heat, while heavy rains caused disruptions in regions like Hawaii and New York.
In Pakistan, unique weather patterns pose even more challenges. The country frequently deals with heavy rains, intense heat, and dust storms, which can lead to system failures. For example, storms in Lahore in 2023 left many without power for hours, and similar incidents occurred during severe floods in Karachi in previous years.
Extreme heat also affects the efficiency of power systems. Higher temperatures can damage transformers, resulting in poorer performance. Energy systems were designed based on weather patterns from decades ago, making them ill-equipped to handle today’s extremes. Regular maintenance and upgrades are vital to ensure these systems can withstand harsh conditions.
Dust and humidity can also contribute to system failures. Dust settles on power lines, while humidity can cause electrical issues. This has led to notable outages in areas managed by the Sindh Transmission & Dispatch Company. Engineering solutions are available, but they require careful planning and investment to keep the grid reliable.
After the 2022 floods, the National Electric Power Regulatory Authority (NEPRA) highlighted the need for better weather monitoring and emergency planning. This includes working with experts on tower design and maintenance to improve stability against strong winds and other weather impacts.
Using Geographic Information Systems (GIS) and a solid asset management strategy can help ensure that the power infrastructure meets current needs. Plans like K-Electric’s Investment 2030 aim to improve reliability through proactive maintenance and smart interventions, like raising distribution infrastructure in flood-prone areas.
To prepare for future climate impacts, the Ministry of Energy and the Ministry of Climate Change in Pakistan need to integrate their efforts. This involves investing in energy efficiency and looking into financial mechanisms for additional support. Smart planning and collaboration with countries already facing these issues can help build resilience.
Ultimately, as climate change alters weather patterns, it’s essential to create a stable, dependable power grid for millions of consumers who rely on it every day. There’s a sustainable energy future within reach, but it will require commitment and coordinated action.
