Went for a walk for lunch and the temperature was very pleasant (a great time of year to be in Brisbane). On returning to the office, however, I glanced at NEM-Watch and saw the at the regional demand had not yet budged out of the blue-zone:
[in NEM-Watch each region is colour-coded on a sliding scale between dark blue (being minimum demand experienced in recent years, generally around 04:00) and red (being all-time maximum demand, which for QLD is experienced on hot summer days]
Powering up NEM-Review I produced this intriguing trend of the average demand between 12:00-14:00 each day this year to date:
We can see that the lunchtime demand peaked this calendar year late in January, and has been trending downwards ever since. To compare across several years, we run the Chronological Comparison and generate time-of-day demand shapes for June/July months over the past couple years (and colour-code for ease of reference):
The monthly average demand shape for July 2013 (to date) is the lowest of the lot, across all hours.
Undoubtedly, the rush of people (several in our office included) getting their 5kW solar PV systems installed prior to the 30 June 2013 cut-off for eligibility for the 44c/kW net feed-in tariff has had some effect. We wonder how many of these other factors are also at work here (keeping in mind that the demand at 4am is also lower)?
