Following James’ comment, and knowing my full schedule for next week means that I (hopefully!) should not get distracted with more analysis, I’ve added this chart from NEM-Review to highlight how reduced exports from Queensland to NSW (because of constraint limitations, due to the outage mentioned) coincided with the price drop in Queensland:
Paul was one of the founders of Global-Roam in February 2000. He is currently the CEO of the company and the principal author of WattClarity. Writing for WattClarity has become a natural extension of his work in understanding the electricity market, enabling him to lead the team in developing better software for clients.
Before co-founding the company, Paul worked as a Mechanical Engineer for the Queensland Electricity Commission in the early 1990s. He also gained international experience in Japan, the United States, Canada, the UK, and Argentina as part of his ES Cornwall Memorial Scholarship.
Following from an alert to the situation provided by NEM-Watch, Duncan Hughes published an article “Power Price Jump in Eye of the Storm” that mentioned the extremely low levels of NEM-Wide Instantaneous Reserve Plant Margin (IRPM) that had occurred for a 60-minute period over both days.
Coincidentally this week it seems to me that we’re facing storm warnings on two different fronts – one literal (and much easier to prepare for), whilst the other one is metaphorical and operates at several different levels (and is much, much more difficult to manage).
Alerted to a price spike at 09:45 this morning in the QLD region, we discovered some reduction in load (spot-exposed Demand Response probably) and also a large collective trip in Solar Farm output (reasons unclear).
