Greenko group, which is constructing the world’s leading pumped hydro storage facility (1,680 MW) near Kurnool, Andhra Pradesh, is expending above billion dollars in devices to three more such facilities in the upcoming three years. Among these, two will be the same size and the third one-and-half times as immense, having a storage volume of 50 GWhr.

The Kurnool plant is likely to be commissioned by December 2023. A third of the power will be provided to Greenko’s green hydrogen and green ammonia capability at the Kakinada port, where the green ammonia will be exported. In all, Greenko will capitalise $6 billion, the Chief Operating Officer said. Senior Advisor at Greenko noted that the group would produce 3 million tons of green hydrogen annually. The first shipment will conduct in December 2025.

The world’s principal is the impelled storage talent coming up at the Pinnapuram village of the Kurnool district. It is an “off-stream”, a locked loop, where water transfers from a lower reservoir to the upper and back, as obligatory. The electricity for water pumping to the higher reservoir comes from Greenko’s 1,000 MW of solar and 550 MW of wind plants.

The facility can source peak-time electricity for 6 hours. A power has slender to be sold at a tariff of Rs 4.23 a kWhr—inexpensive than the price of electricity from new coal ventures, totalling that the company had transported in many innovations in the project design.
