"Do I read the article correctly to say the capital cost for the 63 turbines in the farm will be about $9 million? (That's around $143,000 per turbine - seems realistic.) Surely they do not mean $9 million for each of 20 years, $180 million in total?"

No.

Ok, I am involved with BnB and the 3MW turbines to be installed on my
farm will cost five million Dollars each.

EVERYONE SHOULD DO THEIR HOMEWORK ON WIND INDUSTRIAL SITES. THIS SITE OF NOW 69 TURBINES WILL COST OVER 300 MILLION DOLLARS. 3-4 MILLION DOLLARS EACH ENVIRONMENTALLY DAMAGING TURBINE. I SUGGEST PEOPLE WHO HAVE A BRAIN GO TO THE COUNTRY GUARDIAN WEBSITE AND FIND OUT FACTS AND NOT FICTION ABOUT WIND TURBINE SITES. THIS PARTICULAR ONE AT BUNGENDORE IS NOW IN THE PROCESS OF DESTROYING LISTED BIRD SANCTUARIES AND REMNANT BUSHLAND (SUPPOSEDLY PROTECTED). THIS IS A MONEY GRAB AND NOTHING TO DO WITH EMISSIONS. WHO IS PAYING WHO IN THE NSW GOVERNMENT. 12,000 TRUCKS WITH CONCRETE WILL BE USED TO DELIVER THE BASES OF THE INDIAN TURBINES; I HAVE WITNESSED MANY BIRD CASUALTIES FROM 125 TURBINE METRE HIGH BLADES TURNING AT 200KLM A HOUR. HOPEFULLY NOW THAT THE MOTHER COMPANY BABCOCK AND BROWN IS GOING BUST THERE MAY BE SOME HOPE FOR THE COLLAPSE OF THIS DISASTER ZONE. I AM NOT SUPRISED AT THE GUTTER PRESS APPROACH BY THE SYDNEY MORNING HERALD AS THEY CONSTANTLY GET THE FACTS WRONG ON THIS ISSUE JUST READ THE SO CALLED ENVIRONMENTAL REPORTER WENDY FREW. WHAT A JOKE.
OPEN YOUR MIND AND THINK READ ABOUT THE ISSUES SURROUNDING THIS TOPIC. WHAT ABOUT THE FIRES THAT ARE A REGULAR FEATURE OF TURBINES.THIS AREA IS THE MOST FIRE PRONE IN NSW AND VERY CLOSE TO CANBERRA I CAN JUST SEE ANOTHER 2003 FIRE HAPPENING.
