Dear Market Participant,

Following a pricing event on 24 January 2019 when the Imbalance Settlement Price rose to levels above the strike price in a number of Trading Periods, a dispute was raised by a market participant under the SEM Trading and Settlement Code (TSC) and its Framework Agreement.  The substantive issue of the dispute related to the fact that on 24 January 2019 the North-South tie-line was flagged as a binding constraint and was constrained in a south to north direction, with the effect that RoI plants were unable to solve marginal increases in system load in SEM.  Accordingly difference charges applied in the market for non-delivery of capacity pursuant to the capacity market rules. 

Pursuant to a decision of a Dispute Resolution Board  (DRB) in July 2019, a rebate of monies from the capacity market Socialisation Fund was made to this previously disputing market participant. 

SEMO now informs market participants pursuant to Section B.19.1.2 of the Code of a similar dispute requesting a rebate of capacity market Difference Payments paid with respect to 24 January 2019.  This dispute was received by SEMO within the timelines provided in the TSC and is set for hearing by a constituted DRB on 17 December 2019.

Kind regards,
