Aggregated energy data of the control block Switzerland

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.

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. The data are reliable from 6 months onwards, until then the partners from the electricity sector who provide Swissgrid with the data can still claim changes.

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.

Content

  • Total energy production Swiss control block
    The total of the produced energy fed into the control block Switzerland
  • Total energy consumption Swiss control block
    The total of the consumed energy in the control block Switzerland
  • Total energy consumed by end users in the Swiss control block
    The total of the end- users energy consumption includes all aggregated energy consumed by end- users in the Swiss Control block
  • Vertical load Swiss transmission grid
    The amount of power flows out of the transmission system into distribution and large customer grids
  • Net outflow of the Swiss transmission grid
    The net outflow is the energy, which effectively (time synchronized netting of infeed and outflow) flows out of the transmission grid into the distribution grids, towards end-users and power plants
  • Grid feed-in Swiss transmission grid
    The total of the vertical in feed into the Swiss transmission grid is the sum of all time series in feeds over transformers and lines into the transmission grid
  • Production and consumption of secondary control energy
    The total of the sourced and fed in energy, which generating units have supplied and sourced with secondary control energy based on an ancillary services contract
  • Production and consumption of tertiary control energy
    The total of the sourced and fed in energy, which generating units have supplied and sourced with tertiary control energy based on an ancillary services contract
  • Cross border exchange
    The flow of energy over all transmission lines by each Swiss border
  • Import / export / transit
    Import/export: Summary of all transmission lines to a total energy flow in one direction. Transit: Export minus import as long as the export is bigger than the import.
  • Control energy prices
    Average prices of control energy per 15 minutes rounded to two decimal places for secondary and tertiary control energy products

Imbalance of the control area and activated balancing energy

Swissgrid publishes data to indicate the position of the Swiss Contol Area. The data originates from real-time systems and are published in Excel and CSV formats. The subsequently determined and verified data can differ from the values published below.

  • Abgedeckte Bedarf der aFRR+
    Activated positive secondary control energy for the swiss control area per 15 minutes
  • Abgedeckte Bedarf der aFRR-
    Activated negative secondary control energy for the swiss control area per 15 minutes
  • Abgedeckte Bedarf der SA mFRR+
    Activated positive tertiary control energy (scheduled activations) for the swiss control area per 15 minutes
  • Abgedeckte Bedarf der SA mFRR-
    Activated negative tertiary control energy (scheduled activations) for the swiss control area per 15 minutes
  • Abgedeckte Bedarf der DA mFRR+
    Activated positive tertiary control reserve (direct activations) for the swiss control area per 15 minutes
  • Abgedeckte Bedarf der DA mFRR-
    Activated negative tertiary control reserve (direct activations) for the swiss control area 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

Swissgrid participates in the international cooperation «Trans European Replacement Reserve Exchange» (TERRE) for the realisation of a common market for slow tertiary control energy.

  • Abgedeckte Bedarf der RR+
    Activated positive tertiary control energy from TERRE for the swiss control area per 15 minutes
  • Abgedeckte Bedarf der RR-
    Activated negative tertiary control energy from TERRE for the swiss control area per 15 minutes
  • FRCE+ (Import)
    Imported energy based on imbalance and frequency deviation of the swiss control area
  • FRCE- (Export)
    Exported energy based on imbalance and frequency deviation of the swiss 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.
