What Council Does
About 440 consumers are connected to Stewart Island's electricity supply, which is owned and managed by Stewart Island Electrical Supply Authority (SIESA).
SIESA's network is powered by five diesel generators at a central power station and the power is delivered by 30km of overhead lines, 10km of underground cables and 35 distribution transformers.
SIESA is also investigating the possibility of alternative power generation through renewable resources such as wind and solar, with wind turbines and solar panels installed on the island last year in a trial. Right House, a subsidiary of Meridian Energy, and SIESA are partners in this trial.
The Rakiura Resource Recovery Centre and waste collection on the island are also managed by SIESA.
The SIESA website is www.siesa.co.nz
