Last week National Grid ESO announced that it has begun to use a novel new tool for measuring grid inertia. One of the challenges of managing an electricity system with a large amount of intermittent generation is maintaining grid frequency within operational tolerances. If [...]
Current high gas prices combined with a period of low wind output in September have re-awakened concern about security of supply, including among the general public – today my doctor asked me if he was going to be able to charge his car when [...]
From 1 April 2023 the way that Balancing Services Use of System (“BSUoS”) costs are recovered could change - Ofgem is proposing to exempt generators from the charges and to recover the costs solely from end consumers. This would likely prompt a reduction in [...]
Yesterday, National grid ESO published a preliminary Winter Outlook for next winter (2021/22), deciding to come out with an early view following last winter’s market tightness, which I discussed in a series of posts last month: With tight margins and high prices, was Winter [...]
This morning, National Grid has announced the acquisition of Western Power Distribution (“WPD”), the largest of Britain’s distribution network operators (“DNOs”), in a move that signals a transformation for the company and for the GB electricity system more broadly. At the same time, National [...]
The 1 GW BritNed interconnector linking GB with the Netherlands has suffered another fault and is expected to be out of service until late April, meaning it has spent much of this winter out of action. In addition to contributing to a tight GB [...]
When people talk about digitisation in energy the things that spring to mind are often use of sensors to gather more granular consumption information, and more sophisticated market and system data platforms, allowing new forms of trading and optimisation. Another interesting area is the [...]
The importance of security of supply has been underlined this week by events in the US state of Texas which has been hit by extensive power outages as unprecedented cold weather saw temperatures fall as low as -22 oC, leaving millions of homes without [...]
This month, Statkraft and ABB announced the construction of two synchronous condensers on Lister Driver in Liverpool. The Lister Drive project will provide a range of grid stabilisation services to National Grid ESO, including inertia, short circuit current and voltage control. Grid stability in [...]
On 1 January 2021, the UK left the EU's internal energy market (“IEM”), meaning that trading over the interconnectors between GB and the EU us no longer be managed through market coupling (except for Northern Ireland which remains part of the Single Electricity Market [...]
