Grid & Controls

Your building has flexibility. The grid pays for it.

BoltOS, ThresholdStack's OEM-agnostic energy controller, coordinates solar, storage, EV charging, and HVAC against real-time grid signals. Enrollment, dispatch, and settlement handled on the platform.

From insight to operation

The model that found your savings can also run your building.

BuiltLedger's twin feeds a controller at the edge that acts: shave the demand peak, shift the battery, pre-cool ahead of a grid event. Policy set in software, decisions executed locally in real time on NVIDIA Jetson.

Demand response

Enroll in utility and PJM grid programs. The controller responds to events automatically, inside limits you set.

Storage dispatch

Battery arbitrage against your tariff. Charge cheap, discharge at peak, keep resilience reserve intact.

DER coordination

Solar, storage, EV chargers, and flexible HVAC managed as one portfolio asset, whatever the OEM.

Verified performance

Every dispatch metered and logged. Grid revenue that stands up to settlement.

BoltOS Controller

One building, 24 hours.

The controller running a full day on a time-of-use tariff. It charges the battery when power is cheap, discharges through the peak, and holds site import under the meter's demand cap. Every command in this run cleared the safety kernel.

$0.09

Off-peak $/kWh. Hours 20 to 11, the charge window.

$0.42

Peak $/kWh. Hours 12 to 19, 4.7× off-peak.

50 kW

Peak discharge. Battery, eight hours out.

51 kW

Cap held. Import pinned to the demand cap.

Commands, all safety-gated. 2 relinquished.

Power in kW. Bars are the battery: below the line it charges, above it discharges. Hours in UTC.

How we stage it: grid services are delivered in stages: observe, model, advise, then close the loop within guardrails you approve. We tell you which stage your site is in. The BoltOS run above is a simulator run against contract v1.1.0. It has not touched a live building yet, and live-BAS commissioning is the gate to shipped.
