There's a new article here where Vector is complaining that the govt isn't moving on EV charging to get a smart charging setup. I think the idea is that the chargers should be controllable like some water heating, where the power controllers can disable them during peak times since many people charging cars plug them in when they get home (peak time) but don't care if it's charged then or some time overnight so long as it's charged by morning.
This is an opportunity to have smart chargers retrieve a spot price and change their charging schedule based on this. We should also have smart solar setups where they charge a battery, then feed into the grid at peak times.
The open data situation for electricity information in New Zealand is “pretty good”. The main problem is that people in charge see commercial value in up-to-date cost and usage information so the “free data” is delayed. This prevents people from using near real-time data to improve efficiency of their own power systems.
What's the barrier here? Data comes from the manager of the national grid, which is the government (Transpower), so what's the commercial barrier to releasing that info? Transpower have nothing to gain.
