About the team

Our Power Systems Engineering team, along with both Power Systems Development and Engineering Assurance teams in the System Operator, work closely with electricity industry participants to understand how their assets perform against their obligations, as well as studying and understanding existing and future power system risks and technologies.

In doing so the teams ensure our National Coordination Centre (balancing power supply and demand in real time), and the wider System Operator teams have access to the right information, models and engineering support for operating the electricity market and power system.

Our Power Systems Engineering team are experts in power system modelling and analysis and support the Engineering Assurance (Commissioning) Team, by reviewing power system connection studies provided by Asset Owners and Generators.

They review risks and impacts to the System Operator as a result of connection, to ensure compliance to the electricity industry participation code.

They also produce industry information including the following
