EnOS™ Storage turns every MWh of battery capacity into a safer, smarter digital power plant, transforming raw telemetry into reliable, real-world decisions.

 

Driving Growth in Clean Energy

Founded in 2010, Harmony Energy is one of the UK’s leading developers, owners, and operators of grid scale energy storage projects. With a portfolio spanning the UK, France, New Zealand, Poland, Germany, and Italy, the company is dedicated to enabling a sustainable future powered by renewables.

As their portfolio of battery energy storage systems (BESS) expanded, Harmony Energy faced growing complexity in managing diverse OEM stacks, contracts, and performance data. To keep pace, Harmony Energy partnered with Univers to help unify operations and streamline performance management.

 

The Challenge of Scaling Storage Fleets

What was once manageable on a site-by-site basis soon required a centralised approach to ensure reliability and efficiency across the entire fleet. The Harmony Energy team needed a unified and scalable Energy Management System (EMS) to coordinate operations end-to-end.

Key challenges included:

  • Limited visibility into real-time performance for effective battery storage monitoring.
  • Difficulty integrating multiple OEMs, vendors, and BESS controllers into a single framework.
  • Manual tracking of round-trip efficiency, OEM compliance, and battery management system (BMS) performance.
  • Challenges pinpointing issues in supporting infrastructure, from PCS and HVAC to transformers and fire protection.

 

One Platform, Many Answers

To overcome these challenges, Harmony Energy turned to EnOS™ Storage, Univers’ modular, AI-powered energy storage solution. Already deployed across three of Harmony’s priority sites (with a fourth underway), EnOS™ Storage has become a trusted EMS for their portfolio.

  • The solution delivers the capabilities needed to operate grid-scale BESS with confidence :
  • Unified Asset Monitoring – Consistent KPIs across mixed OEMs, role-based dashboards, and drill-down views from fleet level to racks or cells.
  • Battery Storage Control with Guardrails – A dedicated Control Cockpit ensures safe dispatch, SoC validation, and warranty protection.
  • Audit-Grade Reporting – Automated insights turn raw data into concise reports for boards, lenders, and insurers, strengthening trust in asset performance.

 

Turning Complexity into Confidence

For Harmony Energy, EnOS™ Storage has transformed operations by delivering enhanced energy management across its fleet of storage assets:

  • Faster investigations – Root causes are isolated in seconds.
  • Reduced false alarms – Smarter analytics cut noise and focus attention on real issues.
  • Warranty assurance – Live dashboards and one-click evidence packs simplify discussions with OEMs and insurers.
  • Higher availability – Blind spots are eliminated, downtime is reduced, and output from renewable energy storage is more reliable.

“EnOS™ Storage is a core system in our software portfolio. It is live on three priority assets with a fourth in rollout. The clarity and consistency of data across different suppliers, and the ability to drill from site-level KPIs down to rack and cell data, are vital to our day-to-day operation, especially when diagnosing technical issues and validating available MW/MWh in real time.” – Ked Shayer, Engineering Director, Harmony Energy

 

Why It Matters for the Future

The rapid rise of advanced battery energy storage systems is outpacing traditional operating models. Owners, traders, and operators now need solutions that unify operations, optimise trading opportunities, and manage risk.

With IoT energy storage connectivity, AI-driven analytics, and governance built in, EnOS™ Storage provides the clarity, control, and credibility needed to make every decision smarter and safer. For Harmony Energy, it means unlocking the full value of battery storage assets at scale while ensuring resilience and reliability across markets.
