Our Network Access Planning engineers are responsible for assessing, co-ordinating and sanctioning the planned release of assets from the National Electricity Transmission System, NETS, for maintenance and commissioning of new connections and equipment.

We use AC and DC transmission system analysis tools to optimise efficient and economic transmission system access and ensure that throughout all the outage scenarios, the transmission system continues to operate safely within the Security and Quality of Supply Standards.

When all outage planning activities are completed, a fully operable outage plan is handed over to the ENCC (Electricity Network Control Centre) to deliver in real-time time scales,

Day in the life of...

Our colleagues are at the heart of the ESO, working hard to operate a safe and reliable electricity system all whilst supporting the transition to a greener, and more efficient system for future generations.
eGAMA

eGAMA (electricity Generator Availability and Margin Analysis) is externally a tool provided to generators/interconnectors to meet their OC2 requirements for providing outage data to NGTE
What happens when there’s a request for an outage?

Every year, the ESO assesses and manages outages on the National Electricity Transmission System across the Scotland, England and Wales.
eNAMS

eNAMS (electricity Network Access Management System) is an NGESO developed tool created to effectively manage asset owners’ electricity system outage requests and to give visibility of those outages to affected users.
