Karnataka Achieves Historic Milestone in Hydroelectric Power Generation
From pioneering India's first hydroelectric power generation in 1902 at Shivanasamudra to emerging as the nation's leading hydel powerhouse today, Karnataka's journey in harnessing water for energy has come full circle. At a time when India is accelerating its transition towards clean energy, the state has reaffirmed its historic leadership with a record-breaking performance in hydroelectric power generation during the 2025-26 fiscal year.
Record-Breaking Output and National Leadership
Blending its century-old legacy infrastructure with improved operational efficiency, the state-owned Karnataka Power Corporation Ltd (KPCL) has achieved an all-time high in hydel power. Powered by bounteous monsoon rains in 2025 and enhanced maintenance practices, the major hydel reservoirs of Karnataka generated a whopping 15,509 million units (MU) in the just concluded fiscal period.
This record output marks a sharp rise from the previous high of 13,853 MU recorded in 2024-25, a year often dubbed as drought-affected. A recent report by the Ministry of Statistics and Programme Implementation highlights Karnataka's enduring leadership in the sector, revealing that the state leads the country in hydroelectric power production with an installed hydel capacity of 3.63 gigawatts. This positions Karnataka well ahead of several northern states that traditionally draw credit due to perennial rivers originating in the Himalayan ranges.
Strategic Infrastructure and Operational Excellence
According to senior engineers at KPCL, this feat was accomplished through a network of strategically located hydel stations. These include four in the Sharavathi Valley, four in the Kali Valley, two each in the Varahi and Kaveri valleys, and one each on the Krishna and Tungabhadra river systems.
The state's achievement is particularly noteworthy considering that nearly half of these hydel generating stations—such as Shivanasamudra, Shimsha, and Sharavathi—are among the oldest hydroelectric facilities in India. A senior engineer from KPTCL explained, "The state could achieve this feat due to sustained operational efficiency and improved maintenance practices in the face of ageing infrastructure."
Gaurav Gupta, additional chief secretary of the Energy Department, emphasized KPCL's efforts, stating, "KPCL has strived to meet the state's power demand. Despite some units at Shivanasamudra, Shimsha, Sharavathi, and Mahatma Gandhi hydroelectric centres being among the oldest in the state, their efficiency is noteworthy. Better maintenance has enabled higher power generation."
Key Contributors and Performance Highlights
A lion's share of the 15,509 million units has come from the Sharavathi and Varahi valleys, which together produced 8,696 MU—the highest ever for these regions. The Sharavathi Valley alone exceeded expectations, generating 5,642 MU against a target of 4,800 MU. Similarly, the Mahatma Gandhi hydroelectric station surpassed its target by producing 643 MU against 549 MU.
Other stations also demonstrated exceptional performance:
- The Gerusoppa station generated 1,644 MU compared to its target of 1,060 MU.
- The Varahi project recorded a substantial jump with 1,599 MU against a target of 1,060 MU.
- Stations including Bhadra, Shimsha, and Mani exceeded their generation targets by significant margins, underlining a statewide trend of enhanced productivity.
Three hydroelectric stations set new all-time records during the year:
- The Mahatma Gandhi power station recorded 643 MU, surpassing its earlier peak of 550 MU in 2021-22.
- Gerusoppa marginally improved upon its long-standing record set in 2007-08.
- The Varahi project posted a strong gain over its previous best, also recorded in 2007-08.
Factors Behind the Success
Energy Minister KJ George attributed the record surge in generation to favourable monsoon conditions and improved reservoir levels, coupled with better asset management and operational efficiency across projects. He pointed out, "Due to significant rainfall last year and excellent maintenance of power stations, the state's hydroelectric stations have achieved record power production."
This achievement not only underscores Karnataka's pivotal role in India's clean energy transition but also showcases how legacy infrastructure, when managed with modern efficiency, can drive sustainable growth. As the nation continues to prioritize renewable energy sources, Karnataka's model of blending historical assets with contemporary practices sets a benchmark for other states to follow.
