Balancing services
Reactive power services are how we make sure voltage levels on the system remain within a given range, above or below nominal voltage levels. We instruct generators or other asset owners to either…
Balancing services
The Obligatory Reactive Power Service (ORPS) is the provision of varying reactive power output. At any given output generators may be requested to produce or absorb reactive power to help manage…

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…
Networks
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…

A 36-bus equivalent network representing the National Electricity Transmission System of Great Britain was modelled in DIgSILENT PowerFactory. The entire system was split into 36 zones for which the…

Every year, the ESO assesses and manages outages on the National Electricity Transmission System across the Scotland, England and Wales.
Balancing services
The Enhanced Reactive Power Service (ERPS) is suitable for generators who can provide reactive power over and above the Grid Code and Obligatory Reactive Power Service (ORPS) requirements. On this…
Strategic Energy Planning
The Holistic Network Design (HND) is a first of its kind, integrated approach for connecting 23GW of offshore wind to Great Britain.By considering future offshore generation out to 2030,…
Balancing services
Reactive power services are how we ensure voltage levels on the system remain within a given range, as mandated in the SQSS (Security and Quality of Supply Standard). We instruct generators or other…
