Yellow 2 Gen Energy Pvt. Ltd. Gurgaon URL: www.yellow.org.in
WHY? Our primary purpose is to optimally utilize under-utilized natural resources while addressing the paradox of ‘scarcity amidst plenty’ in context of renewable energy penetration.
Why go land-neutral?
Land has multiple uses – opportunity cost ¡ Land acquisition
URBAN INDUSTRY SETTLEMENTS AGRICULTURE PLANTATIONS PASTURES
Land requires preparation

Why go land-neutral?
Shadows Ambient temperature
Land is scarce
Wasteland available Might be suitable ?
Dust
Efficiency losses in land based plants
4
Land, wherever available, for power plants sub-optimally utilize energy available from the sun
W H Y ?
Why go land-neutral?
Land neutral – environmentally benign
Land neutral - Integrated with water based livelihoods
Impacts Ecology Enhances ecology
5
Floating Solar on water bodies while overcoming constraints can be well integrated with the context

At scale Floating Solar PV power plant can save evaporation of 12.5 BCM/annum
This is equivalent to annual water requirement of 43 million households
W H A T ?
WHERE? Floating Solar PV power plants are possible in a variety of abundant yet under-utilised settings, such as abandoned mining sites, lakes and ponds available in urban and rural settings, multi-purpose dams, water reservoirs within industries inter alia…
Development model – target group A. Large dams – targeted for utility scale power plants
B. Village ponds – targeted for energy access
C. Lakes in urban local bodies – targeted towards conservation
