The short version is that electricity delivery forecast is managed by a financial optimization process. Market participants (generators, line owners, and consumers) basically buy and sell their electricity in advance. Sometimes as far ahead as 2 years, all the way up to the day before (at which time the real time market takes over IIRC).
So in addition to the primary stakeholders you have financial participants that buy/sell electricity without having access to any apparatus for the generation/transmission/consumption. These participants sometimes have very manual processes for buying their contracts.
My guess would be some poor fresh grad was under supervised and transposed the source and sink address. Instead of buying at 203.40 they sold at 203.40 by reversing the source and sink.

(AFAIK the bidding resolver is a proprietary black box provided by a contractor.)

This is after the national grid operator planned to intervene as necessary and imposed some restrictions on trading [1], but those seem to have been lifted and the intra-day market is working (at 10× normal volumes).
