Carnegie Clean Energy Limited (ASX:CCE) shares were down 10.00% at $0.135 during the Trading session on 22 October 2026, at the time of the data. During the trading session on 22 October 2026, the S&P/ASX 200 stood at 8,792.20, down 0.44%, while the All Ordinaries stood at 8,916.20, down 0.45%. Carnegie is an ocean energy technology developer and owns the CETO and MoorPower technologies, which capture energy from ocean waves and convert it into electricity. In an ASX announcement dated 22 September 2026, the company provided an update on fabrication, assembly and deployment preparation under its ACHIEVE Programme at the Biscay Marine Energy Platform in Spain.

About the Company

Carnegie Clean Energy is listed on the Australian Securities Exchange under the ticker CCE. The company describes itself as a technology developer focused on delivering ocean energy technologies. Carnegie Technologies Spain and CETO Wave Energy Ireland are wholly owned subsidiaries of the group, and the latest project activity is centred on the Biscay Marine Energy Platform, known as BiMEP, in the Basque Country, Spain.

Business Overview

Carnegie is the owner and developer of the CETO and MoorPower technologies. According to the company, these systems capture energy from ocean waves and convert it into electricity. It states that it applies artificial intelligence and electric machines to control the technologies.

The ACHIEVE Programme is the vehicle for CETO's grid-connected build and installation at BiMEP. Carnegie will deploy and operate a CETO prototype at the open ocean site, and the data collected will be used to validate the performance of the CETO technology as it moves along its commercialisation pathway.

Foundations and Buoyant Actuator Progress

In its announcement dated 22 September 2026, Carnegie reported that the finishing touches had been completed on the foundation structures in preparation for deployment.

The modular Buoyant Actuator was reported as nearing completion in the Basque Country. Its modular configuration was designed to make fabrication and transport easier, so that moving the structure to the port does not require significant traffic management. Once complete, the Buoyant Actuator will be transported to the port and prepared for the first stage of ACHIEVE deployment at BiMEP, due to begin in October 2026.

Power Take-Off Module Assembly

The same announcement said fabrication and assembly of the power take-off modules had continued with Supply chain partners. Carnegie noted that interface challenges between suppliers had been addressed by its technical team, producing learnings from the first CETO rotary electric power take-off system built.

The modules integrate all the power generating equipment. Testing of the modules will be undertaken near the deployment site to commission the assembly ahead of its offshore deployment in the second stage of ACHIEVE. The company said deployment and onshore testing would validate three years of project-specific design and construction of the CETO technology.

Funding Behind the ACHIEVE Programme

Carnegie outlined that the programme is delivered through its subsidiaries. CETO Wave Energy Ireland works under contract to the EuropeWave Buyers Group, while Carnegie Technologies Spain is supported by funding from the Spanish Government through the RENMARINAS Demos Programme and by a grant from the Basque Government through the Ente Vasco de la Energia.

Related Sector Context

Wave energy sits within the wider ocean and marine renewables field, where developers test devices in open water before any commercial deployment. The announcement referred to European Commission targets of 100MW of ocean energy by 2027 and at least 1GW by 2030. With the S&P/ASX 200 down 0.44% and the All Ordinaries down 0.45%, the broader market also traded lower during the session.

Risks to Weigh In

The company's update itself points to several uncertainties. Interface challenges between suppliers were encountered during assembly of the power take-off modules, which Carnegie described as a first-of-kind system. The prototype will operate in an open ocean environment, where performance data has yet to be collected, and the staged deployment depends on sequencing between the Buoyant Actuator, onshore testing and the second offshore stage.

Timing is another factor, since the schedule relies on fabrication, transport and port preparation being completed as planned. The programme also depends on funding arrangements involving European, Spanish and Basque public bodies.

Catalysts on Watch

Milestones stated in the announcement include the completion of the Buoyant Actuator, its transport to the port, and the start of deployment at BiMEP in October 2026. Further steps are the nearby testing and commissioning of the power take-off modules and their later offshore deployment in the second stage of ACHIEVE. Onshore testing and deployment are expected to provide data that validates the CETO design.

Putting It Together

Carnegie Clean Energy traded lower during the 22 October 2026 session, at $0.135, while its most recent update is dated 22 September 2026. That update set out completed foundations, a Buoyant Actuator nearing completion and power take-off modules in assembly, with staged deployment at BiMEP to begin in October 2026.
