Energy Management SoftwareStowgenLive EMS

StowgenLive — 100% Indigenous EMS

India's own Energy Management Software, built entirely in-house by Stowgen Renewables.

Real-Time Monitoring

Live telemetry of voltage, current, SOC, SOH, temperature and power flow across every cell and module.

Trend History

Trend history, alarms, and maintenance scheduling so operators can see how the asset is changing.

Grid Compliance

Automated dispatch, frequency response and grid code compliance for CERC and SERC regulations.

Made in India

100% indigenously developed — no third-party EMS dependency, full IP ownership, customisable for any project.

What the platform covers

  • Offline HMI

    Monitoring and control on site, with no internet connection.

  • Fleet view

    More than one site, from a browser.

  • Dispatch

    Charge and discharge strategies set by the operator.

Why Stowgen

One Partner. Full Lifecycle.

Stowgen Renewables brings a rare combination of in-house software capability and field-proven hardware expertise to every BESS project. Our indigenous StowgenLive EMS eliminates third-party software dependency, giving clients full visibility and control from day one. The same team takes a project from a residential LFP pack to a multi-MWh utility installation, with one point of responsibility from design through commissioning.

  • One contract from design through commissioning
  • In-house commissioning and operations support
  • Hardware and EMS software from the same team
  • LFP chemistry, with air cooling and liquid cooling
  • A named engineering team you can meet
  • Specification packs issued with the proposal
