Don’t Lower Lakes

October 13, 2008

Re-bottlenecks push up power prices (Oct 4), the reason the power has to return to the South Island in winter is that the lakes have been lowered in February, March and April to supply cheap power to he North Island. Normally this is a low rainfall period, and therefore the storage should be left in the lakes to generate power over winter. Depletion of the storage results in the South Island being unable to generate sufficient for its needs in winter, hence the need for the north to return it to us.

The simple solution is to stop sending power north in this critical period, so there is sufficient capacity left for the south in winter.

Therefore, it is inappropriate for southern power consumers to subsidise for the North Island supply.
