2025 - a transformational year
The 2025 results mark a truly transformational year for the Company. The financial close and commencement of construction of the AW1 Battery Storage project provide a firm platform for significant growth. With construction nearing completion the AW1 project remains on track for operations in Q1 2027, delivering a significant revenue stream as the Company continues its transition from developer to owner and operator of its assets.
The AW1 project demonstrates the value of our project pipeline and our ability to deliver complex battery storage projects. Our portfolio of consented battery storage projects under construction and development is now 2.9GWh and are now actively exploring securing new projects and entering new markets.
Ampeak's team, working closely with its project partners and other development organisations, has been actively identifying and progressing new battery storage projects capable of reaching financial close in the near term. A number of these opportunities, over which Ampeak holds exclusivity, will further expand the portfolio and support delivery against the Company's 2030 target of 2 GWh of battery storage projects in operation, a more than eight times increase over the current AW1 project, and 10 GWh by 2035.
We were delighted to welcome Mr Patrick Hughes as our new 29.6% shareholder, replacing the SIMEC Group. Mr Hughes is the owner of Valencia Waste Management, one of the UK's largest landfill operators. Mr Hughes is supportive of the Company's vision for growth, and we continue to discuss opportunities to partner with Mr Hughes and his other businesses.
These achievements reflect the journey we are on, the milestones we have achieved, and, most importantly, where we are heading as a leading developer, owner, and operator of sustainable energy projects.
None of this would be possible without a world-class team, a strong track record of delivery, and the continued support of the Company's shareholders.
Duncan Black, Chairman of Ampeak, commented:
"I have been privileged to chair the Board through one of the most extraordinary years in the Company's history. We have progressed from promise to delivery; from planning to construction; from SAE to Ampeak Energy. The pipeline we possess, the relationships we have established, and the team we have built give me great confidence that the years ahead will be at least as momentous as the one just concluded. The Uskmouth Sustainable Energy Park is on track to become one of the largest battery storage sites in the UK, and Ampeak Energy is on its way to establishing itself as a leading Independent Power Producer in sustainable energy."
Graham Reid, Chief Executive Officer of Ampeak, commented:
"We enter 2026 in the strongest position in our Company's history. AW1 is under construction. AW2 is consented and development is progressing. The Mey BESS project has full consent and is progressing. Our supply chain partnerships are in place, with Canadian Solar SES committed to supplying batteries for our future pipeline. Our optimisation partnership with EDF provides commercial certainty for AW1 operations. And our name - Ampeak Energy - signals clearly who we are and what we stand for."
