In​‍​‌‍​‍‌​‍​‌‍​‍‌ Ladakh’s remote valleys, a region where life has depended on the seasonal melting of snow and ice for a long time, melting glaciers in Ladakh cut power supply to remote villages, disturbing the daily lives of people. As glaciers that have been around for ages are getting smaller due to increasing temperatures, the streams coming from the glaciers that were used for micro-hydro plants are drying up, thus communities are becoming less and less secure.

Hydropower Fades with Glacial Run‑off

Small hydropower stations located in the upper parts of the Zanskar Valley used to provide electricity to the villages that were far apart by using the meltwater flow. However, as the Sheila Kumik glacier is retreating and its meltwater is diverting from the already established channels, the number of streams has reduced in several places.

Due to irregular water flows, micro-hydro units like Haftal Sani have been closed for years, and that is the reason they cannot be repaired, while the rest also have difficulty in producing enough power. What happens for a short time in run-off can drastically change generation capacity, which may even become zero in the winter months when the streams stay frozen due to low temperatures.

Life Without Reliable Electricity

Low-powered families annually experience a decrease in their power supply, which results in the use of generators running on diesel and firewood mainly for heating during the long winter months when temperature falls to minus 30 °C.

The local businesses, such as small hotels and tea stalls, are also victims of electricity shortage, which prevents them from developing tourism, a source of income that is very important for the region, which is already isolated. Attempts to put in place off-grid solar solutions have had some positive results: a few community solar plants provide limited lighting, while others were damaged by the harsh snowfall conditions, leading to complete darkness in some households.

Seeking Sustainable Solutions

Experts and local officials agree that the cause of the erratic water supply is climate change, which is the main reason for faster glacier melt, and that is why precipitation is changing in the high Himalayas.

Besides the possibilities of large hydro projects on major rivers like the Suru and Indus that are being considered, local agencies are also encouraging renewable energy sources. Solar panels on the roof and community off-grid systems are two such solutions, but they must be strong enough to endure the extreme weather and the seasonal variations.

Devices such as artificial ice reservoirs meant to store winter water for use in warmer months are being tested to prepare for the shortage of natural meltwater. In the end, it can be said that melting glaciers in Ladakh cut power supply to remote villages, thus pointing out the need for energy adaptive planning that is capable of supporting both climate resilience and sustainable livelihoods in one of the most vulnerable regions of ​‍​‌‍​‍‌​‍​‌‍​‍‌India.
