Coalition conversations – power supply

One of our local weaknesses under the Labour/Green Coalition is scant attention paid to security of supply. The NZ Climate Science Coalition has knowledgeable power engineers who keep in touch with it. — RT

Secondly with the large number of wind farms and solar panels the hydro stations are easily turned on and off to supply power at night and when the wind stops blowing . I have seen comments that hydro power stations only have a life of 30 years but Arapuni the oldest station was commissioned around 1930 and Karapiro was commissioned in the late 1940s . Now the latest is that dammed water has dammed dead vegetation that gives off dammed methane over time . If that is all people have against dams that is dam funny . We have seen two small hydro projects scuttled in the North King… Read more »
