Lakes Tekapo and Pukaki represent almost 60% of New Zealand’s total storage capacity for hydro-electric generation. At week’s end, national storage was at 2,020 GW/h, 68% of the average for this time of the year. National inflows for the last seven days were 50% of the average.

Changes to the M-co EPI
Currently the M-co EPI is calculated for each region using the average price from four regionally representative points (or ‘nodes’[*]). It is calculated using information from every period of the seven days up to and including the index date. This calculation is weighted by the demand at all nodes in the region.
To further enhance the accuracy of the index, from Sunday 13 May 2001, M-co will calculate the EPI using price and demand information at all nodes within the region (as opposed to prices from the regionally representative points and demand at all nodes in the region).
The new calculations will mean prices from 1 March 2001 alter very slightly from those originally released. If you use previously released EPI information, please ensure you replace the indices from 1 March onwards with the attached figures.

[*] A ‘node’ is a designated point of connection to the National Grid. It can be either a grid injection point, where generators input electricity, or a grid exit point, where retailers or direct consumers are supplied with electricity. The New Zealand Electricity Market records prices at around 250 nodes.
