In late 2013 Contact Energy announced its proposed $400 million Waitahora windfarm east of Dannevirke was unlikely to be started before resource consent expired at the end of last year, but Mr Brown said the decision to allow the consent to lapse was "very unexpected".
"Late last year Meridian's Taihape project was extended and so we fully expected Contact to apply for an extension here," he said. "We were talking to Contact up until November last year and they said they hadn't made up their minds."
Mr Brown said his Guardians group were glad the consent for the Waitahora windfarm had been restricted to five years, but it fully expected it to be rolled over for a further five.
"Meridian's Puketoi windfarm 40km south of Dannevirke was consented for 10 years, but it seems Contact's Waitahora project was uneconomic.
The company has built a geothermal plant and with the reduction in electricity use and demand not rising like it was 10 years ago and the surge in LED lighting, even for street lighting, it means we retain our pristine landscape out here," he said.
"Throughout the process the Guardians were supported by people who understood our view and we're very grateful."
