The commencement of drilling for India’s first geothermal power project in the Puga Valley of Leh marks a historic milestone in the country’s journey towards sustainable energy. Managed by the ONGC, this one-megawatt pilot initiative not only represents a significant leap in harnessing renewable energy but also underscores India’s commitment to addressing environmental concerns and climate change. Located at a staggering altitude of over 14,000 feet, the geo-thermally active Puga Valley presents both a unique opportunity and a formidable challenge. The project had faced delays due to technical issues and environmental concerns raised by local activists. However, these concerns have been addressed. The foundation work, known as the Celler Pit, is complete, paving the way for the drilling of a 1,000-meter well. Beyond electricity generation, it promises to aid in space heating for the local populace during the harsh winters, support aquaculture and agriculture, and even boost tourism through attractions like lagoon spas. Such holistic utilisation of geothermal energy aligns perfectly with sustainable development goals, fostering economic growth while preserving environmental integrity.
The partnership of the UT Administration of Ladakh, the Ladakh Autonomous Hill Development Council-Leh, and ONGC envisions a phased development approach. Phase 1 will focus on generating one megawatt of power with a free supply to the public, demonstrating immediate community benefits. Subsequent phases aim for deeper exploration and higher-capacity plants, potentially unlocking commercial opportunities. The involvement of international experts, particularly consultants from Iceland known for their geothermal prowess, adds a layer of confidence in the project’s success. The potential of the Puga Valley, spanning five square kilometers, along with nearby promising sites like Chumathang, could lead to a cumulative capacity exceeding 200 megawatts. This not only augurs well for Ladakh’s energy independence but also sets a precedent for geothermal projects across India. No environmentally hazardous chemicals will be used, as the project’s adherence to eco-friendly practices will be crucial in maintaining the delicate balance of the region’s ecosystem. The development of Ladakh has been a top priority of the Government, and this project will be a big leap in that direction.
