Automated demand response,
at scale.
Flexigrid implements the OpenADR 2.0 standard to receive utility dispatch signals and automatically coordinate response across every enrolled site—delivering grid flexibility without any manual intervention.
What is OpenADR?
OpenADR (Open Automated Demand Response) is an OASIS open standard that defines a machine-to-machine communication protocol for demand response signals. It eliminates manual phone calls and manual curtailment by letting utilities automatically broadcast events to enrolled participants who respond in seconds.
Flexigrid acts as both a Virtual Top Node (VTN)—receiving and relaying signals from utilities—and manages a fleet of Virtual End Nodes (VENs) embedded at each site, creating a fully automated demand response pipeline from grid signal to device action.
How a DR event flows
From utility signal to device response in under 5 minutes.
Issues OpenADR 2.0 event payloads via HTTPS/XMPP. Defines event type, signal level, intervals, and target VEN groups.
Receives VTN events, evaluates enrolled sites, calculates available flexibility, and dispatches optimized control commands to each VEN in the portfolio.
Embedded agent at each site that executes control actions—curtailing loads, discharging batteries, or shedding non-critical circuits—and reports back actual response.

DR program types
Flexigrid supports multiple OpenADR signal types, each mapped to a program category with different triggers, actions, and compensation structures.

What Flexigrid handles end-to-end so your team doesn't have to.
OpenADR 2.0b Compliant
Full support for the OASIS standard profile. Flexigrid operates as a certified VTN/VEN intermediary, compatible with any compliant utility system.
Event Lifecycle Management
Tracks every DR event from creation through active, completed, and cancelled states. Opt-in/opt-out is logged per site for audit and settlement.
Granular Signal Types
Supports SIMPLE, ELECTRICITY_PRICE, LOAD_DISPATCH, and LOAD_CONTROL signal payloads—mapping utility signals to device-level actions automatically.
Real-Time Telemetry Reports
VEN nodes stream interval meter data back to the VTN during events. Flexigrid aggregates and validates reported performance for settlement.
Baseline & M&V
Automated baseline calculation (CAISO, PJM, and custom methods) and measurement & verification reporting ensure accurate curtailment accounting.
Enrollment & Registration
Self-service site enrollment with capacity declaration, resource type tagging, and program-level opt-in managed through the Flexigrid dashboard.
Why aggregation matters
Small reductions. Big impact.
A single site responding to a DR event can deliver a few kilowatts of curtailment. Flexigrid aggregates hundreds of sites, turning those individual reductions into megawatt-scale grid resources that qualify for utility capacity markets and ancillary service programs that no single site could access alone.
Aggregation also means each site bears less curtailment burden. The platform distributes response obligations proportionally—so no single facility is over-curtailed, and customers barely notice an event is happening.
