Ampeak Energy Reports Transformational 2025 Results as Battery Storage Projects Advance

That matters because AW1 has now moved beyond planning and promise. Ampeak says construction is nearing completion and the project remains on track for operations in Q1 2027.

For a smaller listed energy company, that is a serious milestone. It gives investors something more tangible to work with, because once AW1 is operating, management expects it to deliver a significant revenue stream.

My read is simple: this is the strongest part of the announcement. Companies in the energy infrastructure space often get valued on whether they can turn concepts into funded, buildable assets. On that test, Ampeak has made real progress.

AW2 and MeyBESS planning permissions expand the battery storage pipeline to 2.9GWh

Ampeak did not stop at AW1. It also received planning permission for AW2, a 1,250MWh battery storage project, and for MeyBESS, a 1,200MWh project.

Together with AW1, the company says its portfolio of consented battery storage projects under construction and development is now 2.9GWh. That is a large step up in scale and gives the group a much bigger project base than it had before.

This is the strategic attraction in the story. If AW1 proves the delivery model, AW2 and MeyBESS provide the next possible legs of growth.

There is also ambition beyond that. Ampeak says it is actively exploring new projects and new markets, with some opportunities under exclusivity, and is targeting 2GWh of battery storage projects in operation by 2030 and 10GWh by 2035.

Those are long-term goals, not current output. Investors should treat them as targets rather than bankable numbers, but they do show the intended scale.

MeyGen tidal energy output adds substance, but battery storage is still the main market focus

The company’s MeyGen tidal stream project generated more than 87GWh of predictable tidal energy in 2025. That gives Ampeak a second operational leg and supports its wider sustainable energy credentials.

Management also says work continues to bring an additional 59MW of tidal capacity to financial close. Again, that phrase is important because it signals a push to move projects from development to funded execution.

Still, if you are trying to work out what is likely to drive the equity story in the near term, battery storage looks more central than tidal. That is where most of the milestone news sits in this RNS.

Debt, cash burn and shrinking net assets: the weaker side of the Ampeak results

Now for the part investors should not gloss over. Yes, debt excluding non-recourse debt fell to £12.7 million from £13.7 million, which is a positive.

Non-recourse debt means borrowing tied to a specific project rather than being fully backed by the wider group. Excluding it can be useful, but it also means you need to pay attention to what is and is not included in the debt figure.

The bigger issue is that cash burn rose to £6.8 million and net assets fell to £6.8 million. That is a steep reduction from £17.2 million a year earlier and tells you the company has far less balance sheet cushion than before.

That does not cancel out the operational progress, but it does raise the stakes. When a business is building aggressively, delivery needs to stay on schedule because the room for error can narrow quite quickly.

Patrick Hughes becomes a 29.6% shareholder and replaces SIMEC Group

Another notable development is the arrival of Mr Patrick Hughes as a new 29.6% shareholder, replacing the SIMEC Group. The company says he owns Valencia Waste Management, one of the UK’s largest landfill operators.

Management says Mr Hughes is supportive of the growth vision and that discussions are ongoing about partnering with him and his other businesses. No financial details of any potential partnership are disclosed, so investors should not assume too much yet.

Still, a supportive near-30% shareholder can matter. It can help with strategic backing and market confidence, particularly for a company in a capital-intensive stage of growth.

What Ampeak Energy’s 2025 final results mean for investors in 2026

This RNS is positive on operations and more cautious on finances. That is the honest takeaway.

The bull case is easy enough to see: AW1 has reached financial close, is under construction, and is targeted to start operating in Q1 2027. AW2 and MeyBESS are consented, the battery pipeline is now 2.9GWh, and the company has supply chain and optimisation partnerships in place with Canadian Solar SES and EDF respectively.

The bear case is also straightforward: EBITDA has fallen hard, cash burn has increased, and net assets have dropped materially. The business may be transforming, but it is doing so while carrying a tighter financial position.

On balance, I think this was a good operational update wrapped inside a still-stretched set of financial results. If Ampeak can bring AW1 into operation on time and keep converting the wider pipeline, 2025 may indeed prove transformational. If execution slips, the weaker balance sheet metrics will start to matter a lot more.

For now, this is a progress story, not a finished one. And for retail investors, that distinction is the bit that really matters.
