Utility Scale Storage

Japan Credit Rating Agency (JCR), Japan’s leading rating agency, has assigned Adani Green Energy Ltd (AGEL) a long-term foreign currency credit rating of BBB+ with a Stable outlook, at par with India’s sovereign credit rating of BBB+.

Luminous Power Technologies has inaugurated its first lithium-ion battery assembly line at Baddi, Himachal Pradesh. This new line is designed to produce standalone lithium-ion battery packs, stationary battery energy storage systems (BESS), and automotive battery packs for e-rickshaw applications.

The European Union added 27.1 GWh of battery energy storage capacity in 2025, with utility-scale systems accounting for the majority of new installations as residential storage declined amid lower electricity prices and reduced support schemes, according to a new report from SolarPower Europe.

India must mobilise around $145 billion in annual energy investment to sustain economic growth while pushing its net-zero ambitions. The bulk of this capital will be directed toward scaling up renewable power generation, grid infrastructure modernization, and energy storage, according to Wood Mackenzie.

New 2.4 GWh adiabatic compressed air energy storage (CAES) plant now operational in in Jiangsu province. The large-scale CAES uses molten salt and pressurized thermal water storage to achieve high efficiency, with power generated through two 300 MW units.

The upcoming budget must prioritize in-house technology and equipment development, provide clarity on delayed power purchase agreements (PPAs) and power sale agreements (PSAs), increase budgetary allocation and policy support for Green Energy Corridors, introduce production-linked incentives for battery energy storage system (BESS) manufacturing, establish an Approved List of BESS Integrators (ALBI), lower the cost of capital through priority sector lending, extend ALMM for solar cells, and continue the ISTS waiver, among other measures.

Conceived for stationary energy storage, the proposed sodium-ion battery configuration relies on an P2-type cathode material and an hard carbon anode material that reportedly ensure full-cell performance. Electrochemical testing revealed initial capacities of 200 mAh/g for the cathode and 360 mAh/g for the anode with capacity retentions of 42% and 67.4% after 100 cycles.

The system operator regularly had to curtail solar generation as an emergency measure to maintain grid security, as other resources were already flexing to their maximum capabilities. Lost solar generation highlights the need for flexibility to grow at pace with solar capacity.

Ahead of the presentation of the Union Budget 2026–27, stakeholders across India’s solar and energy storage ecosystem have urged the government to focus on tax reforms, expansion of production-linked incentive (PLI) schemes with targeted allocations, faster viability gap funding (VGF) disbursements, additional funding for residential rooftop solar, improved access to long-term and affordable green finance, and a stronger push for circular economy initiatives and grid modernisation.

Of the 100 MWh battery energy storage system (BESS), 60 MWh was commissioned in Dec. 2025 and the remaining 40 MWh on Jan. 23, 2026.
