Decisions measured in decades. The cost of testing them is trivial by comparison.

Generation, network and grid-transition decisions are irreversible, high-scrutiny, and measured in hundreds of millions — and, unlike public-sector work, they’re not waiting on an election. We model and forecast the scenarios around them, so you commit knowing where the risk sits and how it moves across the life of the asset.

The moment

When a decision outlasts everyone who made it, it has to be right.

The push toward a renewable system is driving large, irreversible capital and infrastructure decisions — generation, network, storage, grid transition — with regulatory scrutiny and public consequence attached. These are measured in decades, and the people who commit to them are rarely the ones who live with how they age.

The forces that decide whether the investment holds sit well beyond the business case: demand and technology shifts, regulation and consenting risk, the pace of the transition, connection and grid constraints, and the community and public consequence that can stall or reshape a project. A decision tested against today’s assumptions alone hasn’t been tested at all.

That’s the work: modelling how the risk and return move across the full life of the asset — not just at the point of sign-off.

What we model

The decisions worth testing before you commit.

The longer the horizon and the larger the capital, the more it pays to model it first. These are the calls we’re built for.

Generation investment

Committing to new generation — and whether the return holds across demand, price and technology scenarios over its life.

Network & capacity

Network, connection or capacity investment — and whether it stands up under load growth, constraint and regulatory scenarios.

Renewable go/no-go

A renewable project decision, where consenting, connection and offtake risk decide whether it’s genuinely a go.

Asset strategy

Asset-life, replacement or retirement strategy — and what different pathways do to risk, cost and resilience over decades.

Grid transition

A technology or grid-transition bet — storage, flexibility, new tech — where the ground is still shifting under the decision.

Public & community consequence

Decisions carrying community consent, environmental or public consequence that can stall, reshape or sink a project.

Worked example

Committing to a long-horizon generation investment.

How we’d approach a decision like this one. Illustrative of the method, not a specific client engagement.

The decision

Should we commit to the generation build?

A business is weighing an irreversible capital decision on new generation, with the renewable push behind it and a favourable current outlook. The payback runs decades, and the case assumes today’s demand, price and regulatory settings largely hold.

What the modelling surfaces
  • How the risk moves across the life of the asset — not just at the point of sign-off
  • The return under different demand, price, regulatory and technology scenarios over decades
  • The consenting, connection and community-consequence exposure that can stall or reshape the project
  • The alternatives — staging, different technology, or partnership — and what each does to risk and return

The output: a clear go / adjust / hold answer, with the evidence behind it — before the capital is committed.

What you get

The decision, modelled. In plain language.

Every engagement answers the same six questions — the ones that decide whether a move works — modelled across realistic scenarios and written so a board and a technical team can both act on it.

Result 01

Know if you can absorb it

Whether your operation has the capacity to take this on — or whether it stretches you past the point of return.

Result 02

See the real return

What it’s likely to cost, what it’s likely to make, and how much confidence you can put on those numbers.

Result 03

Know the risks in advance

What could go wrong, how likely it is, how it shifts over time, and who ends up carrying it if it does.

Result 04

Have alternatives ready

The other routes available, and the safeguards that improve your chances of success and protect your return.

Result 05

See who really decides

Where the decision-making power sits, who’s affected, and where the blind spots are — so it’s made with eyes open.

Result 06

Protect your people

The community, public and consumer consequence a long-horizon project carries — weighed in the analysis, because it can stall or reshape the asset as surely as the economics.

Why Pūtake Labs

Three things that rarely sit together.

You work directly with the two principals — no juniors, no subcontractors, no account managers.

Senior judgement

Decades of business and consulting experience directing the work — the judgement to know which questions actually decide the outcome.

Proprietary forecasting tools

Our own forecasting and scenario-analysis tools, built for this work, digest and quantify everything bearing on the decision and test multiple scenarios.

A wider view

Where the power sits, who’s affected, and what the change does to your people — the part spreadsheets miss and implementations trip over.

Start a conversation

Weighing a long-horizon commitment?

If you’re working through a generation build, a network investment, a renewable go/no-go or an asset strategy, the first conversation costs nothing and commits nothing. Tell us a little about the decision and we’ll be in touch.
