RVUNL To Bring 1,000 MWh Battery Storage Online By September

Rajasthan Rajya Vidyut Utpadan Nigam Ltd will bring 1,000 megawatt-hour (MWh) of its planned 6,000 MWh battery energy storage capacity online by September, with the remaining capacity expected to be completed by September 2027. The move is intended to strengthen the state renewable power ecosystem and reduce curtailment of surplus solar generation. The first tranche will focus on integrating variable renewable output into the grid.

Rajasthan Renewable Energy Corporation Ltd has proposed an additional 6,000 MWh of storage paired with 2,450 megawatt (MW) of solar capacity at the under construction Pugal Solar Park, although tendering has yet to begin pending approval from the regulatory commission. The pairing is designed to co?locate storage with generation to maximise utilisation. Project development timelines will depend on regulatory clearances and procurement schedules.

The Rajasthan Electricity Regulatory Commission has notified Battery Energy Storage System regulations to provide a framework for planning, procurement, ownership and operation of storage assets across the power sector. Under the rules, distribution companies and the State Transmission Utility will periodically assess storage needs and identify substations suitable for battery deployment. The regulations permit multiple ownership models including utility owned, developer owned and consumer owned systems.

Battery systems are expected to store excess daytime solar power and release energy during the evening demand peak, helping to improve grid efficiency and to stabilise voltage and frequency. Competitive bidding will be required for large utility scale projects to ensure cost competitiveness and transparency. Deployment is expected to reduce renewable energy wastage and to defer some conventional capacity investment.

When complete, the combined plans would add around 12,000 MWh of storage across the state, enhancing grid reliability and enabling higher renewable penetration. Officials say the developments aim to reduce curtailment losses and to optimise use of solar resource at lower overall system cost. The staggered rollout through to September 2027 is intended to align storage build out with evolving grid requirements.

Vande Bharat Express To Start From Tripura Soon

Tripura Chief Minister Manik Saha said the Vande Bharat Express will commence operations from Tripura in the coming days after he flagged off the Agartala–Karimganj MEMU service at Agartala Railway Station. He recalled the rail history of the state, noting that a metre-gauge service first arrived in 1964 and that broad gauge reached Agartala in 2008 following national projects and later upgrades under the Act East policy. The event was described as a milestone for regional connectivity and the MEMU was presented as the first electric passenger train to originate from Tripura.\n\nSaha said he..

MEMU Suspension Disrupts Commuters Between Vadodara And Dahod

The Vadodara–Dahod Mainline Electric Multiple Unit (MEMU) service has been temporarily suspended for 26 days after its rake was diverted to Odisha to manage the surge in passenger traffic during the annual Rath Yatra in Puri. Indian Railways redeployed several MEMU rakes from different zones to meet the additional travel demand for the festival scheduled from the seventh of July to the second of August. As a result, train numbers 69233 and 69234 operating between Vadodara and Dahod will remain cancelled for the duration. Railway authorities advised passengers to use alternative train service..
