Technology
Additive control, at protocol level, on the systems you already run.
This page is written for a BMS engineer or a technically literate evaluator. It states what GridAra reads, what it writes, how it signals the market, and where the security and registration work currently stands.
Architecture
One orchestration layer, four levels.
Site inputs feed the IPEOS engine. IPEOS, the Intelligent Precinct Energy Operating System, drives orchestration across the seven-day cycle and presents role-specific views. Every protocol boundary is a standard interface, not a bespoke one.
In detail
What connects, and how.
Integration method
BACnet/IP and Modbus TCP. Read-write access to zone temperatures, AHU supply air, chiller plant status and whole-building demand — using the points your BMS already exposes.
Non-invasive design
GridAra issues additive setpoint adjustments, not replacements of existing control logic. Your sequences, interlocks and safeties are untouched. If the gateway drops, the BMS runs as before.
Demand response signalling
OpenADR 2.0b is the standard GridAra uses to exchange demand response signals with the building and with programme operators.
Dispatch & optimisation
The engine evaluates live and forecast electricity prices and assigns the building's flexibility to its highest-value use each interval — energy cost avoidance, demand-charge reduction, or a demand response event. Forecasting uses machine-learning models trained on Australian market and weather data.
One model, three views
Every stakeholder reads the same reconciled data.
BMS, battery, metering and market data are reconciled once. Each stakeholder sees that single model shaped to the decision in front of them — so the numbers never disagree between the plant room and the boardroom.
Beyond a single building
Precinct coordination.
The same dispatch and optimisation engine that manages one building can manage several on one site as a single system. When one building generates more solar than it can use, IPEOS can direct that surplus to another building on the same connection instead of exporting it. The decision is made every dispatch interval, alongside the battery and load decisions already described.
Three conditions have to be met. The buildings share a single grid connection point. There is common ownership, or an agreement that lets energy move between them. And metering is in place that can attribute energy use and generation to each building accurately, which is what makes internal settlement and reporting possible.
Where those conditions are not met, for example between buildings that are separately owned and separately connected, the arrangement becomes a private distribution network rather than an orchestration layer, with different capital and regulatory requirements. GridAra treats precinct coordination as an extension to pursue site by site, after the building-level deployment is running.
Security posture
Encrypted, bounded, and built to a national framework.
- Encrypted communications between the on-site gateway, the building and GridAra's platform.
- Bounded authority. The gateway can only read its defined point list and write offsets inside the agreed envelope.
- Designed for the Australian Energy Sector Cyber Security Framework (AESCSF). Alignment work is in progress; certification is not yet complete.
