A Conceptual Case Study in Authority-Before-Action

This context illustrates a pre-existing authority pattern, not a sector-specific failure.

Why this exists

To show how trusted automation in critical infrastructure depends on authority, traceability, and governance before action — not after.

In the National Electricity Market, optimisation, forecasting, and system intelligence operate strictly within pre-defined authority boundaries; no model output constitutes permission to act.

What this is

A conceptual governance case study showing how authority-before-action, traceability, and auditability underpin trusted automation in the National Electricity Market. It documents an architectural pattern already present in critical infrastructure operations and maps it to SCIA as a formal governance overlay.

What this is not

Not a proposal to change market rules, dispatch authority, or AEMO operations.

Not an AI deployment plan or product implementation.

Not a critique of market outcomes or operational decisions.

Context

Australia’s National Electricity Market (NEM) already operates one of the world’s most mature real-time control environments. System security, dispatch integrity, and settlement stability are maintained under tight operating margins through explicit authority, defined procedures, and auditable operational artefacts.

AI-assisted capabilities are increasingly used across the NEM ecosystem, including:

demand and generation forecasting (e.g. ST PASA / PD PASA),
fault and contingency prediction,
distributed energy resource (DER) orchestration,
bidding and dispatch decision support.

Forecasts, constraint models, and optimisation engines in the NEM generate recommendations within a tightly governed field. Authority to act remains explicitly assigned to market operators and rule-defined processes. Structural intelligence supports decision-making but does not replace mandate. In this context, action is permitted only when authority is explicitly resolved at the point of execution.

As AI complexity increases, procedural controls alone become insufficient. Governance must be architectural, not retrospective.

Architectural Observation

The NEM demonstrates a critical principle:

Automation is trusted when authority is explicit, bounded, and recorded before action occurs.

Operational actions already occur within pre-defined authority boundaries and generate canonical, time-stamped records that support audit, review, and regulator assurance.

This reflects the broader principle of Authority Before Action as a Structural Constraint, which underpins trusted automation across regulated systems.

Conceptual SCIA Application

SCIA operates as a governance overlay above existing EMS, SCADA, and market systems. It does not replace dispatch authority or operational control.

Coherence Layer

AI recommendations are gated against codified system constraints (e.g. inertia floors, contingency limits, FCAS requirements) before operator consideration. Signals that violate operating limits are blocked upstream.

Meaning Layer

Inputs from multiple models are semantically aligned so recommendations remain consistent with operating definitions and procedures, preventing drift under pressure.

Governance Layer

Each hybrid decision is traceable to its data provenance, the generating model or rule, and the human authority that accepted or rejected it. This produces an Architecture of Record suitable for audit and assurance.

Generative systems increasingly participate in the creation of executive, investigative, and compliance artefacts. SCIA treats document genesis as an execution event requiring authority resolution, provenance clarity, and contextual integrity at the moment of formation. Governance cannot be assumed by escalation pathways; it must be structurally enforced at origin.

Why This Matters

Trusted automation already exists in the NEM. Its legitimacy comes from authority, traceability, and rollback — not algorithmic sophistication.

This pattern is explored more generally in Control-Plane Assurance in Automated Systems, which examines how authority, execution, and rollback must remain inspectable under automation.

SCIA makes this governance pattern explicit, portable, and inspectable across other high-consequence domains.

Status

This page documents a conceptual alignment between SCIA and existing NEM governance practice.

It does not propose changes to market rules, operational authority, or control-room responsibility.

Regulatory Context

Arqua's work in electricity systems includes regulatory input on execution authority and AI-mediated action, including submissions to Ofgem's AI Technical Sandbox consultation. This reflects the sensitivity of electricity markets and operations to unauthorised execution, where governance must operate at the point of action rather than through post-hoc review.
