Western Australia awards $655m Clean Energy Link East contract

Built World

Acciona, GenusPlus and UGL to build 92km of 330kV lines connecting new renewable zones to the grid

Today: WA government awards A$655m contract for CEL-East Stage One

Overview

Updated 2 hours ago

Western Australia has awarded a A$655m ($455m) contract for the first stage of its Clean Energy Link – East transmission project. The work connects new renewable energy zones east of Collie to the state's main power grid.

The project is central to Western Australia's plan to retire its state-owned coal power stations by 2030. It will unlock about 2.3GW of renewable capacity, enough to power roughly one million homes.

Why it matters

If this transmission line is delayed, Western Australia's coal plants may run past 2030 and renewable developers lose their grid connection.

    Acciona, GenusPlus and UGL selected to build new transmission lines and terminals east of Collie.

  2. CEL-East Stage One added to National Renewable Energy Priority List

    Policy

    The project was added to the federal priority list, supporting faster environmental and planning approvals.

  3. WA government announces $1.4 billion Clean Energy Fund

    Funding

    The 2026-27 State Budget included the Clean Energy Fund to support transmission projects like CEL-East.

Scenarios

1

Clean Energy Link East delivers on schedule, coal retires by 2030

Likely Resolves by End of 2030

Discussed by: Western Australian government, Western Power

Stage One is completed by end of 2029 and operational by 2030. The 2.3GW of renewable capacity comes online as planned, enabling the retirement of state-owned coal plants.

2

Construction delays push back completion past 2030

Possible Resolves by End of 2030

Discussed by: Energy analysts, infrastructure observers

Delays in approvals, land access, or construction push Stage One completion past 2030. The coal retirement timeline slips, and renewable developers wait longer for grid connection.

3

Cost overruns require additional state funding

Possible Resolves by End of 2028

Discussed by: Western Australian Auditor General, budget analysts

The A$655m contract value proves insufficient as material and labor costs rise. The state government provides additional funding beyond the $1.4 billion Clean Energy Fund allocation.

Historical Context

2 moments from history that rhyme with this story — and how they unfolded.

2020s

EnergyConnect interconnector (2020s)

A major Australian transmission project connecting New South Wales and South Australia. It faced delays and cost overruns during construction.

Then

The project was delayed and costs rose above initial estimates.

Now

It showed the challenges of large transmission builds in Australia's fragmented energy market.

Why this matters now

CEL-East is a similar large-scale transmission project with comparable risks of delay and cost escalation.

20th century

Western Australia's SWIS grid build-out

The South West Interconnected System was built over decades to connect Perth and the South West region's power stations and population centers.

Then

The grid connected the region's major power sources to demand centers.

Now

It became the backbone of Western Australia's electricity network, now being extended by CEL-East.

Why this matters now

CEL-East extends this decades-old network to new renewable energy zones, continuing the grid's evolution.
