Energy infrastructure development — Western Australia

Major power projects are won in the early years.

Prometheon originates energy projects in Western Australia.

About

A Western Australian energy infrastructure developer.

Prometheon is an energy project development company based in Perth, Western Australia. We work at the origination end of major power projects — identifying and verifying opportunities, and shaping them into credible, investible developments.

In the state's Mid West, Prometheon originated a gas-fired generation project and progressed it through grid, planning and commercial development into an investible position. See the project →

Capabilities

How value is created before construction

Each capability is part of how Prometheon originates and shapes a project — from first opportunity through to an investible development.

01 — Origination

Origination & site identification

Finding and shaping generation opportunities others overlook — reading the grid, the resource and the market to locate developments worth pursuing.

02 — Network

Grid & network access strategy

Establishing viable connection pathways into the SWIS and quantifying Network Access to underpin a project's capacity and revenue position.

03 — Approvals

Planning, land use & approvals

Working with local government and planning frameworks to confirm a development is permissible and clear the path to a buildable site.

04 — Commercial

Market modelling & transaction

Modelling Reserve Capacity Mechanism revenue, building the financial case, and structuring the eventual transaction that realises the value created.

Track record — flagship project

Mid West Power Station

A gas-fired generation project in the Mid West of Western Australia — originated by Prometheon and progressed through grid, planning and commercial development into an investible position.

The Eneabba project site in the Mid West of Western Australia: a high-voltage steel lattice transmission tower and line crossing cleared farmland under a clear blue sky.
The site — Mid West, WA The high-voltage transmission line crossing the site is the project's connection point into the South West Interconnected System (SWIS) — the grid access that anchored the development.

01Origination

Identified and shaped the opportunity

Originated a gas-fired generation development in the Mid West, recognising the site's strategic position within the South West Interconnected System.

02Grid access

Proved a connection pathway into the SWIS

Undertook preliminary work to confirm the project could connect into the South West Interconnected System — the foundational technical hurdle for any new generation asset.

03Planning & land use

Confirmed the development was permissible

Engaged with local government on land-use and planning to establish that generation development could proceed on the site.

04Stakeholder engagement

Engaged the people around the project

Worked with landowners, the local community and relevant authorities to build the support a development like this depends on.

05Revenue certainty

Modelled the reserve capacity revenue

Calculated the project's Network Access Quantity to size its Capacity Credits and forecast Reserve Capacity Payment revenue under the Wholesale Electricity Market.

06Commercial validation

Built the investment case

Developed detailed financial models that confirmed the project's commercial viability and translated the development work into a defensible return.

07Realisation

Divested the development

The development was divested in 2025, realising the value created across origination, grid, planning and commercial development.

Outcome

A project carried from first opportunity to an investible development — and a successful outcome that validated every stage of the work.
