Supplying hydrology information to NZ's hydroelectricity generators
17 August 2010
Ever wondered where hydroelectricity generators get their information on lake levels and river in-flows? Some of it is provided by NIWA, thanks to our comprehensive hydrology monitoring networks around the country.
About 70% of New Zealand's electricity is generated by hydropower, so it is essential for generators to have accurate information about lake levels and river in-flows associated with power-generation facilities.
NIWA maintains a comprehensive network of high-tech monitoring instruments at all major hydro-power sites. This enables complex real-time data to be delivered, via the internet, to energy generators.
Summarised information is also freely available to the public.
