Statkraft Markets GmbH

Sells into the markets for 10 units at 10 sites, 316 MW together, over the 364 days to 27 September 2026. Everything here is measured from published settlement and auction results; wholesale trading is invisible for every optimiser, not just this one. Elexon's balancing mechanism register names it on 9 of the 10; the other 1 are auction registrations, where the name is NESO's and unchecked.

What the book is made of

Performance follows portfolio shape as much as skill: a Scottish, long duration book does a different job from an English one hour book, so the mix belongs beside the money, not in a footnote.

Duration, by megawatt

about 1 hour 186 MW · about 1.5 hours 12 MW · 2 hours and up 60 MW · not published 58 MW

Region, by megawatt

Scotland 50 MW · England and Wales 266 MW

Attribution. A unit belongs to whoever the market registers as its seller today, so a book that changed hands mid year credits the whole year to the current seller. The exception is a battery that re-registered under a new code: it is counted once, under the code it runs on today, and where the earlier code sold through somebody else that seller keeps what it earned. We have recorded optimiser switches since 27 August 2026 and the record deepens from here. Corporate families are not joined: a platform selling through several registered entities appears as several rows on the optimiser list.
