Victoria's 2,000MWh BESS Gets Critical Approval

Australia's federal environmental approval process isn't known for moving fast. The fact that Alternate Path's Murchs Corner BESS entered the EPBC Act queue in late March 2026 and cleared it by May is notable — and indicates how deliberately this project was designed from the start.

The 500MW/2,000MWh Murchs Corner battery energy storage system, located in southwestern Victoria near Darlington-Terang Road, has received its Environment Protection and Biodiversity Conservation Act clearance, overcoming one of the more significant regulatory hurdles in Australia's infrastructure approvals process. For context, 2,000MWh is enough stored energy to power roughly 400,000 average Australian homes for several hours — a meaningful contribution to a grid that's absorbing wind and solar at an accelerating pace.

What Murchs Corner Actually Is — and Where It Sits

The project spans 169 hectares across two freehold parcels, though the actual construction disturbance footprint is projected at around 21 hectares. The BESS infrastructure itself occupies approximately 13 hectares, with a further four hectares allocated north of the existing transmission easement for a cut-in terminal station.

That terminal station connects directly to the existing 500kV Moorabool to Mortlake transmission line — a deliberate design choice that avoids the need for expensive new transmission buildout and, critically, positions the project inside an already-active energy corridor. Choosing an existing 500kV corridor rather than greenfielding new transmission infrastructure is exactly the kind of development logic that gets regulatory approvals moving.

Alternate Path, a Tasmania-based developer, is pursuing the project alongside local landowners Bobby and Clive Jamieson. This landowner partnership structure is worth noting — it's increasingly common in Australian utility-scale storage development and often simplifies both land access and community engagement.

How the EPBC Act Works, and Why This Clearance Matters

The EPBC Act is Australia's primary federal environmental law, and any project that could significantly impact matters of national environmental significance — threatened species, ecological communities, heritage sites — must be referred for assessment. The process can stall projects for months or longer when ecological sensitivities are high and mitigation planning is inadequate.

Murchs Corner cleared it quickly. The reason lies in how the project was sited.

Selecting disturbed agricultural land dominated by introduced species isn't just good environmental practice — it's strategic project design that eliminates the most common EPBC Act bottlenecks before they occur. The referral identified two listed flora species, three listed fauna species, and one potentially present threatened ecological community in the broader project area. The key phrase is "potentially present" — the highly disturbed, cleared nature of the site means that even where protected species could theoretically occur, the actual impact assessment found no significant impact expected.

The project also avoids direct impacts to nearby creeks, except in locations where existing infrastructure already crosses watercourses — meaning the hydrological disruption argument, another common point of regulatory friction, was effectively preempted by site selection.

What They're Actually Protecting (and How)

The environmental strategy here deserves more attention than it typically gets in project announcements. Murchs Corner's broader 65-hectare disturbance envelope — larger than the construction footprint — is designed to provide siting flexibility during detailed design phases. That's not bureaucratic padding; it's a buffer that allows engineers to make adjustments without triggering a new round of environmental assessments.

At decommissioning — projected 20 to 25 years from operation — the plan is to remove all above-ground components for repurposing where possible and return the land to agricultural use. That reversibility argument carries real weight in EPBC referrals, and increasingly with state-level planning authorities as well.

What the project won't generate is a significant local workforce. Six maintenance jobs are anticipated during operations, running intermittently. That's the honest reality of utility-scale battery storage: the construction phase creates employment, but modern BESS facilities are not labor-intensive to run. Framing these projects primarily as job creation engines overstates the case.

The Moorabool-Mortlake Corridor Is Becoming a Storage Hub

Murchs Corner doesn't exist in isolation. Origin Energy's 300MW/650MWh Mortlake BESS — located at the Mortlake Power Station adjacent to the Moorabool to Heywood 500kV line — commenced construction in 2024 and is expected to finish commissioning by late 2026. That project is already in the ground.

The clustering of battery storage projects along this transmission corridor reflects a straightforward infrastructure logic: the Moorabool-Mortlake line runs through Victoria's South-West Renewable Energy Zone, which spans two areas between Macarthur and Darlington, and between Casterton and Balmoral. Where wind generation concentrates, storage follows — because the grid needs somewhere to put the electrons when generation peaks and demand doesn't.

The South-West REZ corridor is shaping up as one of the most active utility-scale storage corridors in Australia, and the transmission infrastructure running through it is now a genuine competitive advantage for project developers.

The Murchs Corner approval follows a productive recent period for EPBC Act clearances nationally. Two battery storage projects totaling 2.15GWh cleared federal environmental assessment earlier in May 2026, and the 1.6GWh grid-forming Rutherglen battery received EPBC approval in March. These aren't isolated wins — they reflect an approvals environment that, for well-designed projects on appropriate sites, is functioning more efficiently than it did even three years ago.

Victoria's Storage Targets Put This in Perspective

Victoria has legislated specific energy storage targets: at least 2.6GW by 2030 and 6.3GW by 2035. The Murchs Corner BESS alone represents 500MW of that 2.6GW target — roughly 19% of the 2030 floor, from a single project.

That sounds significant, and it is. But the 2035 target of 6.3GW requires sustained project delivery at scale, which means the pipeline of projects currently in planning, approvals, and early construction phases matters as much as any individual approval. Getting Murchs Corner through EPBC Act assessment efficiently adds a credible, well-sited project to that pipeline — but the state still needs dozens more to reach its legislated goals.

The real test for projects like Murchs Corner comes next: state-level planning approvals, grid connection agreements, and ultimately financial close. Federal environmental clearance is necessary but not sufficient. What this approval signals to the broader market, though, is that Alternate Path has assembled a project with the site selection and environmental design discipline to move through regulatory processes at pace — and in Victoria's compressed storage build timeline, pace is everything.
