Leading distribution utility deploys…

01 · The challenge

Problem

Frequent unplanned outages on aging distribution assets. SAIDI was rising. The control room had no real-time visibility into asset health.

02 · How we delivered

Solution

Sensor fusion data fabric, anomaly detection, predictive maintenance dispatch. 280,000 assets instrumented; field workforce mobile-first.

03 · Outcome

Impact

Unplanned outages down 32%. SAIDI fell from 184 to 122 minutes. Maintenance cost down 19%. USD 11M of avoided commercial losses in year one.

How we delivered

Programme phases.

Five phases. One accountable team. Every phase had a named decision point and a measurable outcome.

Discovery & alignment

2–3 weeks

Workshops with the Leading Distribution Utility executive team, baseline metrics, target outcome tree, programme governance set up.

Design & architecture

4–6 weeks

Reference architecture, security blueprint, joint squad model agreed. Data model and integration contracts published.

Build & live-parallel

Q2 onwards

Vertical slice built and run live-parallel against the existing system. Continuous integration, daily deploys, weekly business demos.

Cutover & scale

Mid-programme

Phased cutover, audit-aligned reconciliation, scaling out of squads, capability transfer to Leading Distribution Utility teams.

Run & continuous improve

Steady state

Managed run with named SLOs, quarterly value reviews, and a 15% optimisation budget reserved for improvement work.

Engineering view

Architecture overview.

Foundations

Cloud landing zone, identity, network, security baseline. Data fabric with lineage-by-default. Audit-grade observability stack from day one.

Application & integration

Domain-aligned microservices behind a published API surface. Event-driven core with CDC into the data fabric. Live-parallel capability built in, not bolted on.

Trust & governance

RBAC, audit logs, lineage, policy-as-code. Model risk records for every production model. Compliance posture on the executive dashboard, not in a quarterly slide.

Built on

Technology stack.

Production-grade choices, defended by track record. The stack is one engineering decision among many — but a load-bearing one.

Trust by design

Governance & assurance.

01

Programme assurance

Independent assurance reviews at each phase gate. Findings tracked in a single risk register with named owners and remediation deadlines.

02

Security & data

ISO 27001, SOC 2 Type II controls applied throughout. Data lineage captured by default; sensitive data tokenised at the edge.

03

Audit-grade evidence

Every change tracked; every release reproducible. Audit packs assembled automatically for internal and external review.

04

Continuous compliance

Policy-as-code scans on every commit. Compliance posture surfaced on the executive dashboard, not in a quarterly report.

The fastest reduction in field incidents we have ever measured. Twelve months, end to end.

What we learnt

Three things we would do again.

01

12 months from kickoff to first regulated outcome — squad density and decision velocity matter more than headcount.
02

Joint squads with Leading Distribution Utility engineers stayed in place after go-live. Ownership did not transfer in a hand-off — it grew in place.
03

Live-parallel for a meaningful window before cutover bought us trust. The cutover itself was a flag flip, not a war room.
