Larsen & Toubro announced today its renewables business vertical has secured the engineering, procurement and construction (EPC) contract for the development of a grid-connected 116 MW AC solar PV plant integrated with a 241 MWh battery energy storage system (BESS). The project is located at Kajra in the Lakhisarai district of Bihar.

L&T said the EPC order marks an extension of the earlier phase, taking the total co-located storage capacity of the renewable generation site at Lakhisarai to 495 MWh, the largest such project awarded by a state utility in India.

The deployment of a 4-hour BESS alongside intermittent solar generation will enable energy time-shifting, allowing surplus clean energy to be stored and despatched during peak demand periods. The advanced BESS solution will feature liquid cooling technology, ensuring higher power density, improved safety, and extended operational life.

L&T’s renewables business vertical had earlier secured an EPC order for a 275 MW solar PV project in Gujarat, strengthening its portfolio of flexible, efficient and cost-effective clean energy systems.

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.

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.
