A new electricity provider currently in Wgton and Hamilton https://www.flickelectric.co.nz/hello/
Has anyone tried them yet? ( You need to have a smart meter in place ).
They charge a premium on the spot price, and the spot price is always available for you to see to decide whether or not to use power ( I presume that this means dish washers, dryers, and washing machines ) where you are able to control the use.
So, they charge 40c a day for connection and an additional 1.5c a kWh on top of the spot price.
Nothing on their site about buy back from your PV panels.
