Grid asset and outage data

Reliable power depends on knowing the network and its failures. This guide covers grid asset and outage data and how to source it for operations and resilience.

Why asset and outage data matters

Operators and analysts need to understand network assets, their condition, and where and why outages occur, to maintain reliability, plan investment and assess resilience.

The data landscape

• Assets: network components and topology.
• Condition: age, health and maintenance.
• Outages: events, causes and duration.
• Reliability: indices such as SAIDI and SAIFI.

Common use cases

Reliability and resilience analysis, asset-investment planning, outage prediction and response, and benchmarking.

Sourcing considerations

Asset and outage data sits largely with operators and regulators, with varying access and definitions, so harmonisation matters. Reliability indices follow standards but differ in scope.

Delivery and governance

Operations want timely outage feeds; planning uses batches. Most data is non-personal, but critical-infrastructure security applies, and provenance matters for regulated reporting.

In a managed model

A managed partner can combine asset, condition and outage data into a coherent reliability dataset.

Operators and regulators

Reliability depends on knowing assets, condition and outages, which sit largely with operators and regulators with varying access and definitions, so harmonisation matters. Reliability indices (SAIDI, SAIFI) follow standards but differ in scope.

Cadence and security

Operations want timely outage feeds while planning uses batches; critical-infrastructure security applies, and provenance matters for regulated reporting.
