Description

n the EU electricity market, prices may be influenced by some specific factors. Those factors must in certain regulatory circumstances be duly communicated and published. In particular, article 9.6 of the ACER methodology for harmonized imbalance settlement (available here: https://www.acer.europa.eu/en/Electricity/MARKET-CODES/ELECTRICITY-BALANCING/_layouts/15/DocIdRedir.aspx?ID=ACER-2021-99246) introduces the possibility of applying up to three specific components in the imbalance price calculation (scarcity, incentive and financial neutrality). Article 9.7 of the same methodology requires the TSO to publish the values of such components.


Proposed Solution

WG16 advised to use the Price descriptor class in Market Operations Package instead of adding a new price component attribute to the Price class in Market Management Package. Due to this, I request the following list of changes
As this class is going to be used by both American and European sides, it is proposed to move this class to the Market Common Package.
It is proposed to include a new optional String attribute called type. Reason to have this attribute is to allow the usage of ENTSO-E enumerations at ESMP level. Description for this new attribute could be copied from the existing priceType attribute.
Finally, it is proposed to associate the PriceDescriptor class to Price class in Market Management Package with cardinality 0..1 at priceDescriptor side and 0..* at Price side..


Decision

Move class to MarketCommon
Add new attribute "type" of datatype String
Add new association to Price class as 0..1 -> 0..many Price.
