India concludes world’s largest renewables-plus-storage tender at $0.0566595/kWh
Pumped hydro and battery projects, coupled with renewables, offer the world’s lowest peak clean electricity tariff. The tender, which received bids for for 1.62 GW of capacity against the 1.2 GW sought, saw Greenko secure 900 MW of pumped storage capacity and Renew Power 300 MW of battery storage.
The procurement exercise was held to contract 1.2 GW of capacity in the form of assured supply of 600 MW of clean power for six hours daily during peak demand hours – 5.30-9.30am and 5.30pm-12.30am – on a day-ahead, on-demand basis. The successful bids comprised at least 3 GWh of energy storage capacity – pumped hydro or battery storage – plus associated clean energy generation assets.

Hi there, Thanks for your comment, could you please explain to our readers why pumped energy storage and battery storage is “against science”
I understand that Tamil Nadu Generation and Distribution Corp. is currently developing a 2000 MW pumped storage project in India. There are existing pumped storage projects in excess of 3000 MW worldwide, so 900 MW is not unreasonable and certainly not “against science.”
There are several 300+ MW battery storage projects under contract right now and one 100 MW battery operating in Australia. Again, not against science.
Hi Fenki, I cannot be absolutely certain but, under those tender terms stated I understood it to mean bidders would have to offer six hours per day at any point during those two peak windows.
Hey Fenki,
“for six hours daily during peak demand hours – 5.30-9.30am and 5.30pm-12.30am”?? can anyone clarify? should it be ‘off-peak’?”
In India, the demand peaks between 0600-0900 and 1800-2200 hours (give or take a half hour or so). In this tender, the peak hours have been defined as those hours you’ve mentioned and they include the grid peaks we see in India. The tender is structured with a 2 part tariff. A flat predetermined rate for off peak hours and a price discovered (for the peak hours) via a reverse auction (where the lowest bidder for the per kwh tariff wins) So, getting to your point – it is correctly mentioned here
@Max, partly correct. 1. Bidders have to offer power during 24 hours at different flat tariffs (details in response to Fenki) 2. They have to commit to a CUF AND a capacity for this supply. 3. For peaks – Greenko would have to supply 450MW for 6 hours (out of the listed 11) 4. For the rest of the day – they have to calculate and supply an ‘X’ MW so that their commitments on CUF are met (they can exceed their committed CUF of course)

900Mw pumped energy storage, and 300Mw battery storage are very fool and against science !
This large scale energy storage must be hydrogen.

This is awesome
VERY Informative.

Thanks for clearing that up for us Kadu.
