With the Swiss market liberalisation beginning of 2009, Swissgrid in the role as transmission system operator (TSO) and balancing group coordinator receives several energy data aggregations. In the manner of transparent information policy, Swissgrid publishes the following data aggregates which are based on 15 minutes resolution load profiles to the public. Since 2014 the energy overview contains price information of control energy.
The data will be initially published periodical every 15th working day after the end of the previous month. If there are any changes due to data corrections of the data distributors, the update will be done monthly. (Changes are usually within a band of one-tenth of a percent).
The Swiss control block is not covering the Swiss territory by 100%. Liechtenstein, smaller regions in Alsace (France) and around Schaffhausen (Germany) are in the control block, others which are belonging to Switzerland like distribution grids around Laufenburg are not included in the control block. The resulting deviation is smaller the 2 percent.
Imbalance of the control area and activated balancing energy
Swissgrid publishes data to indicate the position of the Swiss Contol Area. The data comes from real-time systems. The subsequently determined and verified data can differ from the values published below.
- SRE+
Activated positive secondary control energy per 15 minutes - SRE-
Activated negative eecondary control energy per 15 minutes
Swissgrid takes part in the International Cooperation IGCC (NRV) to avoid counterbalancing with Secondary Control Energy.
- NRV+ (Import)
Imported positive secondary control energy per 15 minutes - NRV- (Export)
Exported negative secondary control energy per 15 minutes - TRE+
Activated positive tertiary control energy per 15 minutes - TRE-
Activated negative tertiary control energy per 15 minutes
Swissgrid additionally publishes the Area Control Error (ACE) which is the international measurement for the quality of control. It is calculated as follows: ACE = (Pist – Psoll) + k (fist – fsoll) (Source: ENTSO-E Operation Handbook Policy).
- ACE+ (Import)
Imported energy based on imbalance and frequency deviation of the control area - ACE- (Export)
Exported energy based on imbalance and frequency deviation of the control area - Total System Imbalance (Positiv = long / Negativ = short)
Swissgrid publishes the calculated position of the control area per 15 minutes in consideration of the taken actions above
TSO report on balancing
The annual TSO report on balancing in Switzerland is prepared according to Article 60 of Commission Regulation (EU) 2017/2195 establishing a guideline on electricity balancing, referred to in short as «energy balancing guideline» (EB GL). The annual report aggregates data of the balancing market in Switzerland and provides detailed information on the mechanisms applied to maintain a well-functioning and economical balancing market in Switzerland. Additionally, it discusses future developments regarding the balancing sector and their benefits. In the following download section one can find the detailed report.
Total System Imbalance
The following values serve only as an indication of the position of the Swiss control area are not legally binding. The data originates from real-time systems and is published in CSV and/or XLSX format. The subsequently determined and verified billing data may deviate from the figures provided. Any liability of Swissgrid for actions based on the data published here is excluded.
