Stuart Grid — SCADA & Power Plant Control
Telemetry, setpoints, curtailment and compliance in one supervisory layer — the system your DSO, your operator and your auditor all expect to see.
The layer between your plant and the grid operator
SCADA reads every inverter, battery rack, meter and breaker on site and presents them as one plant. Power Plant Control takes the operator's setpoint and splits it across the assets that can actually deliver it.
Grid-code compliance, provable
Active and reactive power control, frequency and voltage response, ramp-rate limits and curtailment — executed on site and logged, so a compliance request is a query rather than a project.
Historian and alarms
Every tag recorded at sub-second resolution and kept. Alarms are ranked, acknowledged and traceable, so a fault has a timeline instead of a story.
Why sites over 1 MW need it
Below a megawatt an EMS is usually enough. Above it, the grid operator starts asking questions only SCADA can answer.
One setpoint, many assets
The operator sends one number. PPC decides which inverter and which battery string delivers it.
Curtailment without downtime
Ramp down to the ordered limit in seconds and back up again, without tripping the plant.
Audit-ready records
Historian data with timestamps that stand up in a grid-code or insurance review.
Vendor-neutral
Modbus, IEC 61850, IEC 60870-5-104 and DNP3 — mixed-vendor plants run as one.
Priced per site, by plant size
Commissioning and grid-code testing are included. Licence covers the site, not the number of tags.
Questions? We’ve got answers.
Most systems are installed and commissioned within 1–2 weeks, depending on site conditions and grid requirements.
Yes. All Stuart ESS units support modular expansion through parallel connection. Start with one unit and add capacity as your needs grow.
Every unit includes advanced protection such as liquid or air cooling, fire suppression, and IP-rated enclosures for reliable operation indoors or outdoors.
Our team assists with installation, grid integration, and ongoing technical support to keep your system running smoothly.
Stuart ESS units are ideal for self-use, peak shaving, backup power, EV charging integration, and utility-scale grid support.
