Major power projects are won in the early years.
Prometheon originates energy projects in Western Australia.
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 →
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.
Origination & site identification
Finding and shaping generation opportunities others overlook — reading the grid, the resource and the market to locate developments worth pursuing.
Grid & network access strategy
Establishing viable connection pathways into the SWIS and quantifying Network Access to underpin a project's capacity and revenue position.
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.
Market modelling & transaction
Modelling Reserve Capacity Mechanism revenue, building the financial case, and structuring the eventual transaction that realises the value created.
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.
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.
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.
Confirmed the development was permissible
Engaged with local government on land-use and planning to establish that generation development could proceed on the site.
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.
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.
Built the investment case
Developed detailed financial models that confirmed the project's commercial viability and translated the development work into a defensible return.
Divested the development
The development was divested in 2025, realising the value created across origination, grid, planning and commercial development.
A project carried from first opportunity to an investible development — and a successful outcome that validated every stage of the work.
Let's talk early-stage development.
Whether you're a landowner, a counterparty in the WA energy market, or an investor looking at origination, Prometheon is open to the right opportunities and partnerships.
