Social Impacts of Geothermal Utilisation in Puga, Ladakh, India


[United Nations University Geothermal Training Program, Iceland]

Access to energy is critical in development of any society in any corner of this planet. Puga is a rural area in Ladakh region of Jammu and Kashmir, India, situated 177 kms away from Leh town. People are heavily dependent on fossil fuels like kerosene, wood for their heating requirements due to absence of reliable electricity grid. Women of the area have to do most of the household chores and it’s the woman who suffers the most as they are not able to use any electrical appliances like washing machines, electric cookstoves etc. Most of their time is spent in collecting fuel and doing the daily chores manually. As a result they do not get opportunities to either earn or get education. Most of the people living in this area send their children to Nomadic Residential School (NRS). The paper focuses on providing 24 hours electricity by installing a Binary power plant to the Nomadic Residential School (NRS) at Puga. With the existing geothermal well and surface temperature of 80°C it is possible to generate more than 60 kW of electricity which is more than enough to electrify the building for 24 hours. It also discusses the design of heating system for the Nomadic Residential School, Puga using the available geothermal fluid. Calculation was made for heat load of the building without insulation (present scenario) and with building insulation. The results show that for long term energy saving it will be good to insulate the building which will reduce the heat load by more than half of the present heat load. This will be a clean energy solution providing comfortable indoor temperature of 20°C (even when outside temperature can go below -20°C). The utilization of Puga geothermal field will provide access to clean and affordable energy (Sustainable Development Goal, SDG-7) along with gender upliftment (SDG 5).
