- Some blame labour for cutting gas exploration permits. Labour responded by saying any permits that would have been issued would not yet be in production. I am against gas but also i think that is hiding another fact - if this happens again, those exploratory permits could be in production by the time that the next event occurs. They are just getting delayed further.
I think this event reinforces our need for the Lake Onslow scheme.
It would add 1200MW to the grid available within minutes and could run at that rate for 4,000 hours though if combined with a home-solar subsidy, could be recharged using solar panels during the day.
We have to stop burning gas. No excuses.
A better way to increase power would be to provide incentives for people to install solar or wind and some battery storage. They pay for most of it....but get some help.
There are already over 30,000 grid-tied residential solar installs. More than 5000 of those were installed in the last 18 months. (EMA) The newer installs have higher capacities because solar is steadily declining in price. If we assume and average of 15kWh / day across the 30,000 installs (based on 141 samples around NZ with the median average output being 14kWh - pvoutput.org) then existing solar capacity would be - average - about 450MWh per day. Much more in the summer and a bit less in the winter. But with battery backup, these same sites can charge up off-peak and reduce the load at peak.....and even help support it.
Far cheaper than any hydro scheme and much faster to implement. The technology is moving along rapidly. The grid is the first thing to fail in earthquake, fire, storm or flood. Spread generation around.
