Transmission System Operator Electricity Market Management IT System for Balancing

The procurement object is the Finnish Transmission System Operator Fingrid's Market Management System for Balancing. The system is used for managing several different electricity reserve market products as well as balancing and managing transfer capacity. Further details of the system to be procured can be found in the Procurement Object document attached. The product will operate the following markets: - Fast Frequency Reserve (FFR) - Frequency Containment Reserve for Disturbances (FCR-D) - Frequency Containment Reserve for Normal operation (FCR-N) - Automatic Frequency Restoration Reserve (aFRR) - manual Frequency Restoration Reserves (mFRR) Some of the markets are primarily operated in joint Nordic or European market places. For these, the procured system acts as a national fallback system. The system will handle standard market functionality such as bid submission, bid processing, bid selection and market clearing. Fingrid utilizes the products in the markets for balancing and transmission management activities. The procured system serves a significant portion of the Fingrid's balancing process functionality. This includes for example calculating the energy activation need as well as determining the required energy bid selections. Also determining the cross-zonal capacity for Day-ahead, Intraday and mFRR is a part of the system's functionality. Transmission management in the procured system consists mainly of control scheduling of the interconnector links as well as transmission line fault handling. It also includes transmission management within the price area for handling congestions. The system will be installed locally on Fingrid's IT premises. As it is a business critical solution, there will be heavy technical requirements for security and architecture.
