Highlights

CETO Buoyant Actuator fabrication was completed ahead of planned November 2026 deployment.
The initial ocean stage at Spain’s BiMEP will test towing, flotation and local offshore operations.
Power take-off assembly and testing continue ahead of a planned spring 2027 grid connection.
The September-quarter update disclosed an increased AUD 3.5 million Loan facility.

Carnegie Clean Energy Limited (ASX:CCE) develops technology that converts ocean-wave motion into electricity, principally through its submerged CETO system and its MoorPower technology. The company's 2026 work has centred on preparing an 80 kW-rated, scaled CETO demonstrator for deployment at the Biscay Marine Energy Platform (BiMEP) in Spain. Its ACHIEVE programme is intended to generate evidence about engineering performance and maintenance requirements before decisions about larger-scale applications.

Fabrication Moves into Offshore Preparation

On 29 October 2026, Carnegie Clean Energy Limited (ASX:CCE) confirmed that fabrication of the CETO Buoyant Actuator had been completed. The structure comprises modular sections manufactured in the Basque Country. The deployment plan calls for transport to the Port of Bilbao, quayside reassembly and installation of finishing elements before the structure is lowered into the water and towed to BiMEP.

The first offshore stage, planned to begin in November, will examine hydrostatic characteristics, towing procedures and the performance of local installation arrangements. An initial mooring system is to be installed at the offshore berth in parallel. Such testing will not establish commercial viability.

Power Systems and the Second Deployment Stage

While the Buoyant Actuator is prepared for its initial deployment, the company is progressing assembly of power take-off modules at SKF. Carnegie Clean Energy Limited (ASX:CCE) reported that physical fit tests had already demonstrated the insertion and removal of the power take-off and electrical modules within the main structure. Its modular approach is designed to permit maintenance at port rather than require every repair to take place offshore.

The company plans an onshore testing programme for mechanical, electrical and control equipment before integrating the modules at the port. The second deployment stage, including a complete system and initial grid connection, is scheduled for spring 2027 following the Basque winter. That timing remains a company plan and depends on outstanding testing and offshore work.

Technical Objectives and Funding Arrangements

The 9 November 2026 ACHIEVE presentation identified six areas of evaluation: commercial design, energy capture, advanced controls, reliability, maintenance and technology development. The demonstrator is rated at 80 kW and approximately half physical scale.

Carnegie Clean Energy Limited (ASX:CCE) has modelled capacity factors of 30% to 50% for certain future commercial-scale installations; these figures are projections, not outcomes achieved by the Spanish demonstrator. The September-quarter report also disclosed that an existing borrowing Facility had been increased to AUD 3.5 million and its Maturity extended to June 2027, aligning financing arrangements with expected project milestones.

Schedule Changes and Commercialisation Risks

The company acknowledged on 29 October that ACHIEVE had progressed beyond its original schedule. First-of-a-kind Manufacturing issues, supply-chain delays, engineering validation and installation planning contributed to the change. Carnegie Clean Energy Limited (ASX:CCE) is undertaking a staged process to manage offshore complexity and obtain data separately on the main structure and the power conversion system.

Further risks involve adverse marine conditions, equipment integration, commissioning and the ability to translate demonstration results into commercially viable arrays. Technical testing may confirm some engineering assumptions while exposing issues requiring redesign. Future revenue-generating deployments would also require suitable projects, funding and contracts; the November programme should not be described as commercial electricity production.

Key Insights

Carnegie's most immediate operational milestones are the initial BiMEP mooring and Buoyant Actuator deployment, followed by power-system testing and planned grid integration in 2027. The scale-up case remains dependent on measured offshore performance, financing and satisfactory completion of an already delayed demonstration programme.
