Question 4.1.18 [NEW]

In the framework of the obligation to report inside information related to the unavailability of capacity engaged in balancing markets, which schema of Urgent Market Messages is applicable to electricity Virtual Power Plants (which can aggregate several technologies such as DER, storage, demand response, etc.)?

Answer: In case of disclosure of inside information, the assets in VPPs usually have low capacity but (combined) in an aggregated way, the VPP can exert influence on the wholesale energy market and its prices.

Provided that the event is a reportable UMM, depending on the VPP arrangements the UMMs may be disclosed using schema III for UMMs. Data Field 13 Remarks should be used to provide all the relevant information. In particular, it should contain the name of the affected product, e.g. the name of the balancing product impacted by the unavailability.
