The answer is blowing in the wind?
Genesis Energy currently produces almost a third of its electricity using renewable sources. These include the Hau Nui wind farm in the Wairarapa and the Waikaremoana, Tongariro and Tekapo hydroelectric schemes. And in November last year it embarked on what must be its most ambitious renewable energy project yet: the Castle Hill Wind Farm on rural land in northern Wairarapa. The initial survey area covered 30,000 hectares, honed down to a total site footprint of 2,000 hectares. This will host up to 286 wind turbines with a potential nominal capacity of up to 860 megawatts of renewable electricity generation. The electricity produced is potentially equivalent to that consumed each year by up to 370,000 average New Zealand households. Consent was granted on 11 June, and Genesis Energy is now looking at the best way to proceed. But whether they begin work in a few months or a few years, forward planning like this is a vital part of creating future renewable energy generating capacity for the country.
