    Waiting to connect: the problems and solutions for network connection queues (Part 2)

    Network connection queues continue to be a notable topic of interest as many generators face significant delays to project development – an issue that is directly conflicting with net zero ambitions and recent focuses on strengthening domestic energy supplies. In Part 1 of our two-part series on connection queues we...

    Up north and down south – trends for generator TNUoS charging

    The topic of generator Transmission Network Use of System (TNUoS) is becoming a subject of increasing interest for stakeholders as regulation, policy, and the generation mix create potential volatility for future charging trends. The significant costs posed through TNUoS are an important consideration for generators, with high variability between regions...

    Turn it up – responding rapidly to manage the system

    In balancing the system, we used to talk mostly about narrowing capacity margins and the need to ensure ‘headroom’. But suddenly there’s a greater need for greater consumption and the provision of ‘footroom’ during COVID-19, and potentially and also in the future. The ESO will need to procure more and...
