Bidding error sees Finnish day-ahead power price tumble

Unless you have a strong familiarity with ISO&#x2F;FTR markets this article will be pretty opaque.<p>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).<p>So in addition to the primary stakeholders you have financial participants that buy&#x2F;sell electricity without having access to any apparatus for the generation&#x2F;transmission&#x2F;consumption. These participants sometimes have very manual processes for buying their contracts.<p>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.

Fingrid published two messages that sound like countermeasures to deal with the fallout: <a href="https:&#x2F;&#x2F;umm.nordpoolgroup.com&#x2F;#&#x2F;messages?publicationDate=all&amp;eventDate=nextweek&amp;companies=N01250" rel="nofollow noreferrer">https:&#x2F;&#x2F;umm.nordpoolgroup.com&#x2F;#&#x2F;messages?publicationDate=all...</a><p>&gt; Fingrid has closed intraday trade in directions FI&gt;SE1 and FI&gt;SE3 to ensure system security and balancing capacities concerning the non-matching situation in the Finland bidding zone after Day-ahead trades. Update: Intraday trade in direction FI&gt;EE closed<p>&gt; Fingrid is prepared to initiate Intraday purchases, if necessary, to ensure system security and balancing capacities concerning the non-matching situation in the Finland bidding zone after Day-ahead trades.

It&#x27;s only -€0.2&#x2F;kWh, not that bad at all. I&#x27;ve been seeing spot price predicted to be -A$1&#x2F;kWh in several states in Australia (which is the lowest possible bid allowed by regulation). Even in Europe, I recall seeing some post desperately trying to figure out how to curtail their solar export because the price was reaching -€0.34&#x2F;kWh. Not sure an error of -€0.2&#x2F;kWh is anything newsworthy TBH.

Sounds like someone at NordPool didn&#x27;t test their black box very well.<p>(AFAIK the bidding resolver is a proprietary black box provided by a contractor.)

This is a very terse note. Is there simply not more information available than &quot;some price went negative on the market because someone made a mistake&quot;, or am I missing something that&#x27;s implied here?

I understand put options and short selling, but how on earth can the price of a commodity sink below zero? How can you make a „sell“ order that is negative? Can someone explain please?

How much money was or will be lost as a result of this? Is this a Knight Capital -level error?

Very strange that no one noticed this error as it was ~60% of Finlands average daily electricity consumption
