What This Article Covers

1.Canal-Top Photovoltaics (CTPV) use elevated structures over canals to generate solar power without additional land, saving nearly 100 acres per 20 MW in Punjab.

2.India's first CTPV installation was in Mehsana, Gujarat (2012); a 1 MW system saves 9 million litres of water annually and generates 1.6 million units of electricity.

3.MNRE's 2014 pilot-cum-demonstration scheme targeted 50 MW each for CTPV and canal bank projects, with financial assistance of Rs 3 crore/MW for CTPV.

The Big Picture
Prelims · HighMains · Medium

India's vast canal network offers a land-free path to solar power via Canal-Top Photovoltaics (CTPV). With land acquisition for solar projects becoming expensive, CTPV saves land, reduces water evaporation, and improves panel efficiency. A 2024 assessment estimates 131 GW potential, but high costs and structural challenges limit deployment. The PM Surya Sarovar Yojana (floating solar) signals growing policy interest in land-neutral solar.

21 GW Renewable Energy Faces Curtailment Due to Transmission Bottlenecks in India

India's renewable energy boom is hitting a critical bottleneck: lack of transmission infrastructure. Nearly 21 GW of capacity operates on temporary grid access, facing severe curtailment (up to 90-95% in some cases), threatening project viability, debt repayment, and potentially creating NPAs for banks that have deployed ₹5.08 lakh crore in the sector.

India Crosses 300 GW Non-Fossil Capacity, Targets 500 GW by 2030; Solar Leads at 164.59 GW

India has crossed 300 GW non-fossil fuel capacity (300.50 GW as of July 31, 2026), accounting for over 54% of total installed capacity. Solar power leads at 164.59 GW. The country is on track for 500 GW by 2030. Key schemes like PM Surya Ghar have benefited 19 lakh households with zero electricity bills. This milestone is crucial for exams on energy transition, climate policy, and government schemes.
