Grid-Scale Energy Storage
VAULTTEC engineers bespoke grid-scale battery and compressed-air storage systems that turn intermittent renewable generation into reliable, dispatchable power.
Our Principles
Every VAULTTEC system is engineered to 98% uptime SLA with redundant battery management systems, real-time thermal monitoring, and instant failover capability across all grid configurations.
We integrate the optimal chemistry for each application — lithium iron phosphate for daily cycling, vanadium flow for long-duration storage, compressed air for multi-day resilience. Performance over ideology.
Our lifecycle analysis considers 25-year total cost of ownership, degradation curves, second-life repurposing, and responsible decommissioning. We engineer for the full arc of the asset.
Storage Systems
Intelligent Management
Every VAULTTEC installation runs our proprietary VAULT OS — an AI-driven energy management platform that forecasts demand, optimises charge/discharge cycles, and participates autonomously in wholesale electricity markets.
VAULT OS integrates with all major SCADA systems and provides real-time telemetry, predictive maintenance alerts, and revenue optimisation analytics through a single dashboard.
Development Process
Modelling of grid constraints, renewable penetration, and ancillary service opportunities to define storage capacity and dispatch profile.
Matching storage chemistry and configuration to the site's operational requirements, land footprint, and 25-year economic model.
Detailed electrical, civil, and control system engineering with safety analysis and grid interconnection studies.
Factory acceptance testing, site installation, system integration, and full capacity testing before grid connection.
24/7 remote monitoring, scheduled maintenance, performance reporting, and market participation optimisation via VAULT OS.
