Otago wind power 'like eating your own veges'

Pioneer Generation's Mt Stuart wind farm is officially open and producing energy, despite a snowy start.

About 5cm of snow settled on the Mt Stuart wind farm yesterday, prompting Pioneer Generation to hold its official opening in the Waitahuna Hall instead of on-site. More than 100 people attended.

Pioneer Generation chief executive Fraser Jonker said the project was completed ahead of schedule, and the company was pleased with the support from the community during the project.

He said Pioneer Generation was looking at six sites for possible wind farms, with most of the testing stations in Clutha, with one on the Clutha-Gore border, and another in Southland.

The Mt Stuart wind farm uses nine 850kW wind-turbine generators, each with a three-bladed rotor 52m in diameter, and a tower height of 45m. They are expected to each produce 2845MWh of electricity a year.

They start producing power when the wind speed reaches 14.5kmh, gaining maximum power at wind speeds above 61kmh.

Resource consent was granted in 2010 for the 7.65MW wind farm on the southwestern side of the Manuka Gorge. It aimed to produce enough electricity to meet the annual energy needs of about 3350 homes.

Farmer Rob Hewett, who owns the Mt Stuart land, said the wind farm was great for everyone, especially the community. He said he floated the idea for a wind farm in 2004, and began measuring wind for a few years, before a larger testing station was created. Later, the site was considered to be viable for a wind farm.

"There's 3000 homes getting power from here - all used locally. It's great for the community, great for everyone really. It's a bit like eating your own veges."

Power generated at the site was used in Balclutha and Milton as well as the area surrounding Mt Stuart.

Mr Jonker said the energy generated by the wind farm was not fed in to the power grid.

Pioneer Generation, based in Alexandra, is 100% owned by the Central Lakes Trust. It owns and operates 13 hydro-electric power stations and one wind farm in Central Otago and Southland.

Mr Jonker said the company was still looking into hydro development, with a probable 50/50 split between hydro and wind interests.

The opening was held in conjunction with Global Wind Day, an annual international celebration of wind energy in 40 countries.

Energy and Resources Minister Phil Heatley yesterday welcomed two significant wind energy milestones - the opening of the Mt Stuart wind farm, and Meridian Energy's announcement work on the Mill Creek wind farm north of Wellington will start soon.

"New Zealand's wind resources are among the best in the world, and the role of wind energy for electricity generation is steadily increasing," Mr Heatley said.

Mt Stuart a great result...

It was a great priviledge to attend the opening of Pioneer Generation's Mt Stuart wind farm on Friday and see how a project like this can be put together to benefit a wide range of community stakeholders, and still succeed in a commercial context.

Congratulations to all those who have had the vision and skills to put in place this wonderful asset that will be contributing to our energy needs quietly, reliably and at very low environmental impact for decades to come.
