Planned 5 GW Ladakh solar plant will be ‘the world’s largest’

India has resumed its contest with China to host the world’s biggest solar park and the projected Ladakh solar project could bring the crown back to south Asia.

According to U.S.-based insurance provider SolarInsure, as of June 2017, China’s Datong Solar Power Project – with a projected capacity of 3 GW – had the potential to become the world’s biggest single-location solar PV project, once completed.

The Ladakh project is expected to be complete by 2023, with abundant sunlight and clear air making Ladakh unusually suitable for solar technologies.

The power generated from the 5 GW PV plant in Leh district will be transmitted, via a 900 km line along the Leh-Manali road, for consumption by Kaithal district in the state of Haryana. It will be supplemented by another 2.5 GW solar project in the Kargil district, to provide electricity to light up the plains and reduce dependence on diesel generators for a population that remains cut off for around half the year.

Storage element

Besides enabling developers to set up the power transmission and evacuation infrastructure, the 7.5 GW Jammu & Kashmir tender encourages them to add storage. Developers are encouraged to explore different forms of storage technology, including battery, molten salts, pumped storage or a combination thereof, for innovative and efficient utilization of the transmission evacuation infrastructure.

A report in the Times of India quoted SK Mishra, director of power systems for the Solar Energy Corporation of India (SECI), as saying: “We have addressed issues faced in previous tenders and taken into account the challenging geography.

“Another positive is the Leh and Kargil administrations have designated 25,000 and 12,500 acres of non-grazing land, respectively, at prices remunerative for the hill councils, which will also earn rental of around Rs1,200 per hectare, per annum, with 3% annual escalation,” he added.
