Renewable Energy and Improved Cooling Technologies Key to Reduce Water Use in India’s Power Sector
New IRENA-WRI analysis finds that urgent action can significantly lower intensities of water withdrawal and consumption, while substantially reducing carbon emissions intensity by 2030
Abu Dhabi, UAE, 16 January 2018 — A new policy brief co-authored by the International Renewable Energy Agency (IRENA) and the World Resources Institute (WRI) finds that increasing the share of renewables, in particular solar photovoltaic (PV) and wind, in India’s power mix, and implementing changes in cooling technologies mandated for thermal power plants would not only lower carbon emissions intensity, but also substantially reduce water withdrawal and consumption intensity of power generation.
The brief, Water Use in India’s Power Generation – Impact of Renewables and Improved Cooling Technologies to 2030, finds that depending on the future energy pathways (IRENA’s REmap 2030 and the Central Electricity Authority of India), a power sector (excluding hydroelectricity) transformation driven by solar PV and wind, coupled with improved cooling technologies in thermal and other renewable power plants, could yield as much as an 84% decrease in water withdrawal intensity by 2030, lower annual water consumption intensity by 25% and reduce carbon emissions intensity by 43%, compared to 2014 levels. It builds off of the findings of Parched Power: Water Demands, Risks, and Opportunities for India’s Power Sector, also launched today by WRI.
“India has emerged as a global leader in renewable energy achieving record-level growth in deployment, rapid cost reductions and many socio-economic benefits of the energy transformation.” said Dr Henning Wuester, IRENA Director of the Knowledge, Policy and Finance Centre (KPFC). “Scaling up the use of renewables, especially solar PV and wind, will yield further benefits, in particular long-term reductions in the dependency of the power sector on freshwater.”
More than four-fifths of India’s electricity is generated from coal, gas and nuclear power plants which rely significantly on freshwater for cooling purposes. Moreover, the power sector’s share in national water consumption is projected to grow from 1.4% to 9% between 2025 and 2050, placing further stress on water resources. Renewable energy, with the added potential to reduce both water demand and carbon emissions, must hence be at the core of India’s energy future.
“India’s move towards renewable energy is essential, especially as water stress puts increasing pressure on India’s thermal power plants,” said Dr O.P. Agarwal, CEO, WRI India. “Water risks to thermal power plants cannot be ignored when considering the cost of thermal energy. Renewables, especially solar PV and wind energy, present a win-win solution for both water and climate.”
About the International Renewable Energy Agency (IRENA)
IRENA is mandated to be the global hub for renewable energy cooperation and information exchange by 150 Members (149 States and the European Union). Roughly 27 additional countries are in the accession process and actively engaged. IRENA promotes the widespread adoption and sustainable use of all forms of renewable energy, in the pursuit of sustainable development, energy access, energy security and low-carbon economic growth and prosperity. www.irena.org
