011 - Earth hour's impact across the states and the years

Earth hour saw its tenth year - a popular event, but one that's been under increasing scrutiny since it's inception in 2007.

The chart below shows demand, either by total for the NEM or state-by-state, for each earth-hour day in those past ten years, compared to the average March Saturday for that year. In some instances, total demand during the day is lower than the average - but impact on demand during the designated hour is usually hard to detect - which reinforces the symbolic nature of the event. Data via NEM-Review.

How has demand changed in the Australian NEM over the past few years? The chart below splits that up by state, and includes minimum and maximum half-hourly demand for each year. Read the market operator's demand forecasting report here - data below via NEM-review, Demand is down, but the maximums haven't changed to quite the same degree.
