Highlights

  • All 20 South Erregulla generating units were commissioned on gas by late June.
  • Grid commissioning began in July, with commercial operations targeted for 1 October 2026.
  • West Erregulla 2P reserves increased 19% to 251 PJ.
  • Walyering West-1 flowed at stabilised rates of 11 MMscf/d from the C1 sand.

Strike Energy (ASX:STX) is within reach of adding a second Revenue stream to its Perth Basin business. The South Erregulla power station has completed mechanical and gas commissioning and is waiting on grid connection ahead of targeted commercial operations on 1 October 2026. At the same time, Strike has reported higher West Erregulla reserves and a successful flow test at Walyering West-1. The combination creates a clearer integrated gas-and-power model, but the company is also navigating Leadership changes, Debt obligations and a grid timetable controlled by external parties.

Recent Developments

Strike took a final Investment decision on the South Erregulla peaking station in November 2024 at an estimated construction cost of AUD 137 million, supported by a AUD 217 million financing package from Macquarie Bank. Mechanical completion came on 11 June 2026, and on 28 June the company reported all 20 reciprocating engines commissioned on gas. Strike then shut the plant into preservation and care and maintenance while it waits on the grid.

Why It Matters

The investment case is that Strike is about to stop being a single-field gas producer with a long list of projects and start being an integrated energy Business with two revenue streams. Capacity payments are contracted, largely insulated from Commodity price swings, and rising. Because South Erregulla's fuel comes from Strike's own licence, the generation Margin is not exposed to third-party gas contracts.

Cash Flow remains central to funding flexibility and balance-sheet strength.

Free Cash Flow will determine how much operating progress reaches the balance sheet.

Capital Expenditure remains a key consideration through the next growth phase.

Earnings growth will determine whether the current operating momentum proves durable.

Supply conditions remain relevant to pricing and project economics.

Company Overview

Strike Energy is a Perth-based gas producer moving into electricity generation, with everything of consequence in Western Australia's Perth Basin. Its producing asset is the Walyering field, which supplies the WA domestic market. Its development Assets are the Greater Erregulla complex — South Erregulla in licence L24, and West Erregulla, where Strike holds a 50% operated interest — plus the Ocean Hill discovery and exploration acreage.

Financial Snapshot

For the half year to 31 December 2025, Strike reported sales revenue of AUD 36 million, underlying EBITDA of AUD 14 million and a post-tax loss of AUD 12.3 million, on production of 3.8 petajoules equivalent. Trailing twelve-month revenue is around AUD 73 million. Power Economics rest on the Reserve Capacity Mechanism. The reserve capacity price for 2027-28 has been set at AUD 360,700 per megawatt; the Economic Regulation Authority's draft determination for 2028-29 is AUD 491,700, a 36% increase driven by a shift in benchmark technology towards battery storage.

What to Watch

The nearest date is 1 October 2026. Confirmation that South Erregulla has been energised, connected and dispatched into the South West Interconnected System would be the clearest proof point Strike has offered in years — and Western Power and AEMO control that timetable, not the company.

Risks

Grid connection is the live risk. The plant is built and idle, carrying fixed costs while it waits on a schedule set by Western Power's maintenance windows. Any slip past the start of the capacity year pushes back the revenue start date. The Balance Sheet is the second.

What Could Turn South Erregulla Into a Second Revenue Stream

The next eight weeks decide whether the market's scepticism has been warranted. Strike has spent AUD 137 million on a power station it cannot yet run, funded partly with debt that begins amortising around the same time.
