SUBSEA PUMPED HYDRO FOR UTILITY SCALE STORAGE AT

Cost of utility scale battery storage India
Currently, the cost of battery-based energy storage in India is INR 10.18/kWh, as discovered in a SECI auction for 500 MW/1000 MWh BESS.. Currently, the cost of battery-based energy storage in India is INR 10.18/kWh, as discovered in a SECI auction for 500 MW/1000 MWh BESS.. We estimate costs for utility-scale lithium-ion battery systems through 2030 in India based on recent U.S. power-purchase agreement (PPA) prices and bottom-up cost analyses of standalone batteries and solar PV-plus-storage systems.. For low storage hours (up to 6-8 hours or so), batteries are more cost-effective. As hours of storage increase, pumped hydro becomes more cost-effective. Over the next 10-15 years, 4-6 hour storage system is found to be cost-effective in India, if agricultural (or other) load could be shifted to solar hours 14. This groundbreaking initiative is supported by The Global Energy Alliance for People and Planet (GEAPP’s) concessional loan amounting to 70% of the total project cost and is in partnership with IndiGrid and BSES Rajdhani Power Limited (BRPL).. According to NITI Aayog and Rocky Mountain Institute estimates, India will account for 800 GW of battery demand per year by 2030. In another report, the Energy Transitions Commission (ETC) projects that the levelized cost of storage systems in India will reduce from $0.41 (~₹30.8)/kWh in 2018 to $0.17 (~₹12.8)/kWh in 2030.

How much does a battery storage system cost in India?
In another report, the Energy Transitions Commission (ETC) projects that the levelized cost of storage systems in India will reduce from $0.41 (~₹30.8)/kWh in 2018 to $0.17 (~₹12.8)/kWh in 2030. The report adopts a two-pronged approach to estimate the cost of Li-ion based MW scale battery storage systems in India.
How much does a battery cost in India?
The report further notes that capital costs for batteries co-located with storage projects in India would fall to $187 (~₹14,074))/kWh in 2020 and $92 (~₹6,924))/kWh in 2030. The levelized cost of storage (LCOS) of standalone BESS is estimated to be ₹7.12/kWh (~$0.095/kWh) by 2020, ₹5.06/kWh (~$0.07/kWh) by 2025, and ₹4.12/kWh (~$0.06/kWh) by 2030.
Could a battery energy storage system help India meet peak demands?
The report further adds that keeping this in mind, an alternative battery energy storage system (BESS) based on low-cost lithium-ion batteries may enable India to meet the morning and evening peak demands. The Ministry of New and Renewable Energy has been tasked with the implementation of the National Energy Storage Mission.
Could low battery storage prices disrupt India's energy needs?
Such low battery storage prices could disrupt how India plans to meet its growing energy needs. Energy, Environment and Water, the International Energy Agency, UC Davis, and the World Resources Institute (CEEW, IEA, UC-DAVIS and WRI 2023), focuses on the vulnerabilities associated with the supply chain of critical minerals used for batteries.
Is battery storage cost effective?
300-400 GWh of battery storage (~10-15% of average daily RE generation) is found to be cost effective by 2030. For low storage hours (up to 6-8 hours or so), batteries are more cost-effective. As hours of storage increase, pumped hydro becomes more cost-effective.
Are battery storage systems cost-effective?
As hours of storage increase, pumped hydro becomes more cost-effective. Co-located battery storage systems are cost-effective up to 10 hours of storage, when compared with adding pumped hydro to existing hydro projects. For new builds, battery storage is always cost-effective irrespective of the hours of storage.

Why did a 50 MW / 100 MWh Bouldercombe battery catch fire?
Genex Power, owner of the 50 MW / 100 MWh Bouldercombe battery which caught fire in Queensland on September 26, says its preliminary root cause analysis found the fault occurred at the grid side of the Tesla Megapack battery unit. The Bouldercombe battery uses Tesla's Megapack technology.
How many battery-related fires occur in Australia a year?
A battery explodes in an Australian recycling plant. A report from Pragmatic Research, funded by waste and recycling bodies, estimated there are between 10,000 and 12,000 battery-related fires in the sector per year. The ACT lost its recycling facility to a battery-related fire in 2022.
Did a Tesla battery burn in Queensland's first large-scale battery storage site?
A Tesla battery has burned within one of Queensland’s first large-scale battery storage sites at Bouldercombe near Rockhampton. (ABC News: Jasmine Hines. "Some of them are sort of quite cheap and might not have the full protections," Mr Parkinson said.
How many fires have lithium batteries caused this year?
So far this year, lithium batteries have caused at least 98 fires, according to data from the Queensland Fire and Emergency Service (QFES). Last year, the batteries caused 108 fires. An investigation is underway after a blaze at one of Queensland's first large-scale battery storage sites on Tuesday night.
Are lithium-ion batteries causing fires in Australia?
Lithium-ion batteries are responsible for thousands of fires in Australia per year. (ABC News: Emily Baker ) CSIRO principal research scientist Dr Adam Best said it was this property that meant they were more prone to a strong reaction when things went wrong.
