Can New Zealand survive repeating tight electricity events?

New Zealand survived a tight electricity supply situation on Friday morning - the 12th so far this year.  It happened after Transpower warned the residual quantum of electricity available for use was sinking towards the 200 megawatt danger mark between 7 am and 9 am. In the end, the 200 megawatt level was not breached, and even if it reached zero, unused reserves would still be available.But it is a predicament that keeps Transpower on constant alert, which it warned about in May and again a month later. This subject and other energy problems are the subject of the latest interest.co.nz Of Interest podcast.  *You can find all episodes of the Of Interest podcast here.
