In reply to Alan Sim of Mt Roskill (Central Leader, August 13), just exactly where is the country supposed to get its power when North Island thermal generation is taken out for maintenance, if not from the Waitaki system?
In the lead-up to winter several of the large North Island coal or gas-fired gener- ation units were shut down for maintenance.
Despite record low inflows into the Waitaki storage lakes, Meridian was forced to draw on those reservoirs to ensure security of electricity supply over that period.
The Waitaki power stations are the cornerstone of the country’s electricity supply system, and readers can be assured that Meridian takes a cautious and responsible approach to managing them.
The fact that we are coming through the winter without major disruption to supplies is more due to the superb management of those assets by Meridian production staff than to the meagre rainfall in the Waitaki catchment over most of the last year.
