NESO publishes Electricity Ten Year Statement
The National Energy System Operator (NESO) has published its Electricity Ten Year Statement (ETYS), providing an assessment of Great Britain (GB)'s future transmission requirements and the capabilities of the National Electricity Transmission System over the next decade. NESO’s ETYS is emphasises four key messages: the necessity for network reinforcement across GB, the importance of timely and coordinated reinforcements to reduce network constraints, a continued focus on voltage management, and the expansion of network planning through the Centralised Strategic Network Plan. The report highlights the need to enhance power transfer capacity between regions to avoid exceeding system capabilities, which could lead to constraint costs. It also identifies the need for increased voltage support, with regions such as Southern and Central Scotland, Northwest England, the East of England, the Midlands, and London requiring high levels of support.
