Danske Commodities A/S

Sells into the markets for 2 units at 2 sites, 56 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 1 of the 2; 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.

Whose batteries it sells

None of the book is its own. The one owner behind it is established from control filings, on the owner pages. A battery that re-registered under a new code is counted once.

What the documents say

The register names who sells; these are the arrangements behind that, from owner and optimiser announcements, each with its kind, because an optimisation agreement, a route to market, a toll, a floor and self-trading are different products with different risk.

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.
