A brief look at peak NEM-Wide Demand over recent winters

This weekend, we have prepared this analysis of the entries we received for our “Peak Demand Forecaster” competition for winter 2009.

In conjunction with this analysis, we thought it would be of interest to also incorporate this chart (generated from a BETA version of the NEM-Review v6 software package) to highlight how the peak NEM-Wide demand unfolded over the previous winters…
