Re­new­ables add Is­land power

Southern Telegraph - - News - Ar­ran Mor­ton

The world’s first grid-con­nected com­bined wave en­ergy and so­lar mi­cro­grid will be tri­alled at Gar­den Is­land, it was an­nounced last week.

The Gar­den Is­land Mi­cro­grid Project will con­sist of the re­verse os­mo­sis de­sali­na­tion plant op­er­at­ing at the is­land and new CETO 6 tech­nol­ogy — the pre­de­ces­sor of which, CETO 5, be­gan pro­vid­ing emis­sions-free power and fresh wa­ter to HMAS Stir­ling ear­lier this year.

Carnegie Wave En­ergy chief ex­ec­u­tive Michael Ot­ta­viano said CETO 6 would add an ad­di­tional 2MW peak of so­lar pho­to­voltaic power gen­er­a­tion and enough en­ergy stor­age to al­low safe, sta­ble and re­li­able in­terac- tion with the elec­tric­ity grid.

“Carnegie sees great po­ten­tial to in­te­grate its world-lead­ing CETO wave tech­nol­ogy into is­lands as well as fringe grid ap­pli­ca­tions wher­ever there is a strong wave re­source,” he said.

Western Power chief ex­ec­u­tive Paul Italiano, whose com­pany will pro­vide an engi­neer and ad­vice for the next six months, said the en­ergy provider saw sig­nif­i­cant po­ten­tial for long-term eco­nomic ben­e­fits in in­creas­ing de­cen­tralised en­ergy gen­er­a­tion near the edges of the grid.

“The pos­si­bil­ity of mi­cro­grids pro­vid­ing a lower-cost al­ter­na­tive to re­plac­ing ageing net­work in­fras­truc­ture is very ex­cit­ing,” he said.
