State utility Rajasthan Rajya Vidyut Utpadan Nigam Ltd (RRVUN) has invited bids to set up standalone battery energy storage systems (BESS), connected to the State Transmission Utility (STU), with an aggregate storage capacity of 2,000 MWh (500 MW x 4 hours). The systems will operate on a single-cycle charging/discharging basis.

The utility company seeks to utilize these energy storage systems on an “on-demand” basis to meet the state’s requirements during peak and off-peak hours.

The Rajasthan utility or RRVUN will enter into a battery energy storage purchase agreement (or BESPA) with the selected bidders for providing energy storage services. The selected BESS developers will be responsible for setting up the systems on a build-own-operate basis with a 12-year contract.

Projects awarded under this Request for Selection will be eligible for central financial assistance in the form of viability gap funding through the Power System Development Fund scheme, issued by the Ministry of Power.

The utility previously aimed for 2 GWh of storage via a tender in late 2024. The announced results of that tender were in June, with Solarworld Energy Solutions won 125 MW/250 MWh at a tariff of ₹221,000 ($2,561)/MW/month, while Oriana Power won 50 MW/100 MWh at ₹222,000 ($2,574)/MW/month. Rays Power Experts won 75 MW/150 MWh at ₹223,000 ($2,586)/MW/month, and JSW Neo Energy grabbed 250 MW/500 MWh at ₹224,000 ($2,597)/MW/month.

When will there be nationwide financing solutions for battery storage systems in Germany? The use of battery storage systems is essential for the success of the energy transition and the best possible use of renewable energies, but also for being able to temporarily store surplus energy from other sources. Technically, there are already solutions for all possible sizes of battery storage systems, from private home storage systems to large-scale storage systems with a capacity of more than 50 MWh. But what about the financing of battery storage systems, is it already offered as standard?

Voltwise: Extend German grid fee exemption for large batteries to 2034 Germany's Federal Network Agency is consulting on a proposed overhaul of its grid fees to introduce a General Grid-Fee System (AgNES). Battery energy storage systems (BESS) are currently exempt from the charges and Voltwise's head of German operations, Thorsten Klöpper, is suggesting a three-stage system which takes account of battery-related grid benefits.

Opinion & Analysis

Falling li-ion battery prices mirror solar photovoltaics trends: Is there a role for second-life batteries before recycling? Lithium-ion batteries are everywhere, powering everything from consumer electronics to electric vehicles, residential PV storage systems, and, more recently, mitigating curtailment in large-scale wind and solar power plants. EVs are driving large-scale demand for Li-ion batteries which will result in substantial volumes of spent batteries in the near future. This scenario highlights the potential for repurposing EV batteries for second-life stationary applications, which could maximise their value before recycling. However, to fully realise this opportunity, several economic, technical, and regulatory challenges must be addressed and resolved.
