'Peaker' plants are typically powered by hydrocarbons such as gas, oil and coal and are used to satisfy peak demand such as after dawn and early evening which is when demand that can be deferred such as EV charging and HWC heating so some type of consumer incentivisation is required to prevent this avoidable demand. EECA is presently inviting input on a green paper that addresses just this issue.(23-08-2022, 10:15 AM)harm_less Wrote: You're living in the past with that comment. Our two EVs mostly run on sunshine, or when the sun doesn't do the job we charge off peak when grid generation is in surplus and prices cheaper.Of course you would charge off peak power when the price is cheaper, but the power still has to be generated doesnt it?
New Zealand burned more coal for electricity production in the first quarter of this year than any quarter in nearly a decade. The revelation comes the day after a "transformational" climate change report that slated successive governments for its inaction on reducing greenhouse gas emissions that continue to rise.

If you're that concerned about the demands put on NZ's grid capacity you would be advised to submit on this.
Also of interest is the real time breakdown of our electricity generation. I note that "Battery" is a recent addition to this and will be interested to see how soon it begins to show outputs, and also the arrival of solar generation in those stat's.
