Chennai, July 20: A weaker-than-expected monsoon has impacted hydropower generation in Tamil Nadu, leading to a sharp decline in electricity output from hydroelectric stations and increasing the state’s dependence on costlier power purchases.
Lower rainfall has resulted in reduced water inflows into reservoirs, affecting the availability of hydel power that plays an important role in meeting the state’s energy requirements. To bridge the gap between demand and supply, power authorities have increased procurement from other sources.
The rise in power purchases is expected to put additional pressure on electricity costs, as market-based procurement can be more expensive compared with locally generated hydroelectric power. Officials are closely tracking rainfall patterns and reservoir levels to manage the situation effectively.
Despite the short-term challenges, Tamil Nadu continues to focus on strengthening its energy mix through renewable sources and improving power infrastructure. Authorities remain committed to ensuring a reliable electricity supply for households, industries, and businesses across the state.
The situation also highlights the need for greater energy diversification and sustainable resource management to address weather-related fluctuations in power generation.
