EMILIA Gate solution profile · GRACE energy controls

A verifiable demand-response rail for AI compute.

When the grid asks an AI datacenter to reduce load, GRACE binds who authorized the exact event, what was allowed, which supplied actuator and meter claims were accepted, and the result computed under a pinned method. The bundle verifies offline without trusting the operator’s application logs. It does not prove physical meter truth or decide settlement.

COSA moves the megawatts. EMILIA binds the authorization, supplied observations, and deterministic result.

WHY NOW

Flexible compute is growing, but grid programs still need evidence they can evaluate.

Duke University’s Nicholas Institute finds the 22 largest U.S. balancing areas could absorb 76–126 GW of new load if it can be curtailed under ~1% of hours — ERCOT alone ≈ 10 GW at 0.5%. But that headroom is only bankable if the curtailment evidence is verifiable enough for a grid operator to evaluate. Today, operators may have to rely heavily on self-reported logs and supplied measurements. GRACE addresses one part of that gap: authorization and tamper-evident evidence over supplied inputs under a pinned method.

HOW IT WORKS

Authorize → verify → shed → measure → compute → package.

1

Authorize

A market-authorized party (ISO, utility, aggregator, or facility under the applicable tariff) signs a bounded grid.curtailment order — named human, or quorum for hard cuts.

2

Verify & gate

The facility controller verifies the order offline, fail-closed: posture changes only against a valid, in-scope, unexpired order. Spoofed or stale orders are refused.

3

Shed

The scheduler reduces compute — cache-first inference, deferred batch, capped GPU clocks — preserving life-safety lanes. Power falls. (COSA moves the megawatts.)

4

Measure

A separately keyed meter or smart PDU signs the supplied telemetry. The public reference simulates this source; its signature authenticates the supplied records but does not prove physical truth or a complete source population.

5

Compute

The reference computes the delivered-load result from accepted inputs under the program’s prescribed baseline method, pinned by hash. This proves deterministic computation from supplied inputs, not physical delivery.

6

Package

A Proof-of-Curtailment Bundle records the accepted order, acknowledgment, meter evidence, and computed result for offline verification. The program separately decides eligibility and settlement under its own rules.

WHO IT'S FOR

One evidence bundle, evaluated under each program’s rules.

AI / HPC datacenters & neoclouds

Present portable evidence of the authorized event, supplied observations, and result computed under the program’s pinned method.

Grid operators / ISOs / utilities

Evaluate supplied curtailment evidence without relying only on the operator’s application logs. Program rules still determine eligibility and settlement.

Demand-response aggregators

Carry a portable, tamper-evident M&V artifact for large, fast flexible loads into the program’s existing review and settlement process.

First mover: an AI/HPC datacenter or neocloud operator with a DR aggregator or utility sponsor — the party that holds the interconnection/payment incentive and a grid counterpart that can evaluate the bundle under its program rules.

DEMONSTRATION

Available now: the full reference circuit, visible end to end.

A runnable reference circuit is published and verifies under the current EMILIA verifier. It issues a grid.curtailment order, simulates a shed, signs separately keyed simulated meter evidence, computes the reference result, and emits the Proof-of-Curtailment Bundle. The adversarial paths refuse tampered telemetry, forged orders, and replay. The control-room view makes each transition inspectable without implying a physical deployment or complete source population. A hardware demonstration with a host-approved compute node and independent meter still requires a facility partner.

HONEST POSTURE

GRACE does not invent the baseline. It makes application of the pinned method tamper-evident.

The baseline methodology belongs to the ISO/program (CAISO ELAP, PJM CBL, ERCOT). GRACE pins its digest and binds the accepted authorization, supplied meter observations, and deterministic computation. The result is tamper-evident under the pinned method and supplied inputs. It does not establish that the readings are physically true or complete, that an event qualifies under a tariff, or what should be paid. Settlement remains a separate program decision.

A deployment may preserve an authenticated OT transport event digest as a distinct evidence leg. That digest does not grant authority or prove the physical outcome.
