Proof

India's First Grid-Scale Battery Was Written Off. Ingro Brought It Back.

Battery racks at Tata Power-DDL's Rohini substation, run by Ingro EMS

Tata Power-DDL · Rohini, Delhi

10 MW / 10 MWh, India's first grid-scale BESS

  1. 2019

    Commissioned at Tata Power-DDL's Rohini substation in Delhi: India's first grid-scale battery, 10 MW / 10 MWh.

  2. 2023

    The original control system could not manage the uneven ageing of batteries and inverters. The recommendation was to replace the whole installation.

  3. 2024

    Ingro replaced the EMS, not the hardware: all 124 power conversion units integrated under one controller, and the plant run under Ingro O&M.

  4. 2026

    Tata Power-DDL issued performance certificates for two consecutive annual terms and renewed the mandate.

FAQ

Questions About Ingro, EMS and BESS

The questions buyers ask us first. All FAQs

5 questions

Ingro Energy is an Indian energy management and battery storage company. It makes Ingro EMS, an energy management system (EMS) for battery storage, solar, diesel generators and EV charging, and delivers battery energy storage end to end: sizing, engineering, installation, commissioning, and operation and maintenance for the life of the asset.

Yes. Ingro EMS works with any make of battery, BMS, PCS and inverter. At India's first grid-scale BESS, the 10 MW / 10 MWh plant at Tata Power-DDL's Rohini substation, Ingro replaced the original EMS instead of the hardware, integrated all 124 power conversion units and has run the plant since.

Start with your own data. Ingro SIMS turns twelve months of electricity bills into a costed solar and storage recommendation with the bill, the saving and the payback, in minutes. For larger or grid-connected projects, Ingro's engineers run a full BESS simulation and feasibility study.

Both. Ingro EMS is supplied to BESS integrators, EPC contractors and developers to go inside the systems they build. Ingro also delivers complete battery energy storage systems under one contract, from planning and procurement to commissioning and long-term O&M.

Yes. Ingro EMS runs rooftop or ground-mounted solar and a new battery as one plant, so on-site generation is used first and surplus is stored instead of exported. Ingro can size the battery from the site's bills, supply and integrate it with the existing inverters, and commission the system.
