Power T&D Industry Pack

Power Transmission & Distribution Forecasting

T&D programmes are governed by outage windows, consents and connection dates — dependencies largely outside your control. The forecast has to model that dependency risk explicitly rather than assume it away.

How the engine works

What breaks forecasts in power t&d

The maths is the same everywhere. These are the sector-specific conditions that make a generic forecast wrong.

Outage windows are granted, not chosen

System operator outages are scheduled far ahead and are hard to move. Missing one usually means waiting for the next planning cycle.

A missed outage can cost two quarters

Consents and wayleaves run long and unpredictably

Easements, planning consent and landowner negotiation have durations set by other parties and routinely exceed the construction they enable.

The longest activity is often paperwork

Connection dates carry contractual liability

Missing a customer or generator connection date has liquidated damages attached. The date is a liability, not just a milestone.

Late connection has a price per day

Long-lead plant dominates the programme

Transformers, GIS and cable carry lead times of a year or more. Order dates, not construction dates, set the achievable programme.

The order date is the real milestone

Energisation testing is late and unforgiving

Commissioning and energisation sit at the very end, where there is no float left, and any defect found is discovered at the worst moment.

Zero float at the highest-risk phase

What's in the Power T&D pack

The engine is identical across industries. The pack is the content that makes it speak your sector's language from the first time you open it.

Worked example

132kV reinforcement, month 14 of 26

BAC $58M. EV $27.9M, AC $30.4M, PV $29.6M. One wayleave is unresolved and the next suitable outage window is 11 weeks away.

CPI
0.92
EAC
$63.1M
LD exposure
$2.4M
P80 energisation
+14 weeks
Cost performance is unremarkable. The forecast that matters is $2.4M of liquidated damages exposure created by a single unresolved wayleave — a legal problem, not a construction one, and no amount of site resource will touch it.

Illustrative figures, shown to demonstrate the method. Your numbers replace them.

Power T&D questions

Yes, each with its own date, duration and the scope allocated to it, so a missed window shows its knock-on immediately.
LD exposure is calculated from the P80 connection date against the contractual date, so it moves as the forecast moves.
As external dependencies with their own duration distributions, since they are not resource-driven and cannot be accelerated.
Yes. Voltage levels and cost codes are configurable; the dependency structure is identical.
