Western Australia leads the world in wave energy #auspol 

Wave energy possesses unique characteristics that offer an advantage over other renewables such as wind and solar energy:
Less variable and with the variability being more gradual and with notice; and

More predictable. Australia’s preeminent research organization, the CSIRO, estimates wave energy is at least three times more predictable than wind energy;

The proximity of favourable wave energy sites to ultimate end users, thereby minimising transmission issues. Notably, approximately 60% of the world’s population lives within 60 kilometres of a coast.


Carnegie’s Mauritian Wave and Microgrid Design Project is focused on the potential for high penetration renewable energy microgrids that incorporate wave energy.
The Project on Mauritius and the neighbouring island of Rodrigues will deliver three outcomes by the end 2016:
1. A renewable energy roadmap for Mauritius, including: technical, commercial and financial feasibility of high penetration renewable energy.
2. An assessment of the Mauritian wave energy resource and the identification of a preferred site for a commercial CETO wave energy project.
3. The design of a microgrid powered desalination plant on the Mauritian island of Rodrigues.
The Project is supported by $800,000 in funding from the Australian and Mauritian Governments.
Australian based Energy Made Clean (EMC), proven specialists in the delivery, construction and operation of microgrids, will assist Carnegie in the delivery of the Mauritian Wave and Microgrid Design Project. This follows the announcement by Carnegie of its Investment and Alliance Agreement with EMC in March 2016.

The CETO 6 Project, located offshore of Garden Island, Western Australia is supported by the Australian Federal Government through a $11m Australian Renewable Energy Agency (ARENA) grant as well as a debt facility from the Commonwealth Bank of Australia.
This next generation CETO unit has a targeted 1MW capacity, representing some four times the output of the previous generation CETO 5 unit (demonstrated as part of the Perth Wave Energy Project).
The concept design is the culmination of work that commenced in 2012 and incorporates lessons learnt from the Perth Wave Energy Project, wave tank testing in Scotland, as well as internal design and modelling studies undertaken with Carnegie’s supply chain.
The CETO 6 design is the CETO product platform that will be used in commercial CETO projects.

CETO 6 offers a higher rated capacity and increased efficiency than previous CETO generations which, when deployed in large commercial arrays, will deliver a levelised cost of energy (LCOE) competitive with offshore wind. Longer term development will continue to push costs lower below this benchmark. It is this technology that will be utilised, developed and adapted for deployment in Cornwall.

The Project will be delivered by Carnegie’s local subsidiary, CWE UK, based at the Hayle Marine Renewable Business Park, with commercial and technical support from its Australian parent company and developer of the CETO wave energy technology, Carnegie Wave Energy. Delivery of the Project will leverage Cornwall’s, and the UK’s, exceptional wave energy resource, marine energy revenue support, maritime industrial heritage, the world class Wave Hub infrastructure, and active and innovative marine engineering and research sectors. Carnegie also expects to utilise the marine energy feed in tariff available in the UK which equates to an estimated £305/MWh for the second stage of the Project.
Deployment and operation of the CETO device will be within a defined berth, awarded to Carnegie in 2014, at Wave Hub. Wave Hub is a facility for testing of wave energy device arrays. It provides a fully grid-connected and consented wave energy site, located approximately 10 nautical miles (16km) off the north coast of Cornwall. The Wave Hub Offshore Deployment Area, which covers 8 km² of seabed, is divided into four separate berths available to lease to wave energy device developers, with a 30MVA grid connection agreement.


Wave Hub unit being deployed 16km offshore from Hayle, Cornwall. The Wave Hub test facility is the world’s largest and most technologically advanced site for the development of offshore renewable energy technology.
The Project will also include engagement with and coordination of a suitable supply chain for the construction and operational phases. The successful demonstration of this Project will present a significant opportunity to commercialise wave energy in the UK through bridging the gap between technology readiness and commercialisation.
