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.
The National Electricity Market (NEM) is designed to operate at 50 Hz. Frequency deviation occurs when generation and load are mismatched. It is important in a lightly meshed and long network such as the NEM to maintain tight frequency control and that frequency response is available throughout the network.
The Callide C4 unit tripped from 420MW in the 5 minutes to 18:36 (NEM time) on Sunday evening 26th October 2025, delivering a sharp drop in mainland frequency.
Some wobbles in System Frequency (NEM mainland) through the middle of the day on Thursday 31st October 2024 stick out, and will be progressively explored.
