CASE STUDY: Nordic Market Management System (NMMS)
Unicorn Systems successfully delivered several versions of the Damas MMS platform for the capacity markets in the Nordic countries.
Project Goal
In 2017, Unicorn Systems a.s. together with Optimeering, were selected as a supplier for the common Nordic Market Management System with the aFRR (automatic Frequency Restoration Reserve) services. Later was decided to extend the scope to mFRR (manual Frequency Restoration Reserve) services. The project is named NMMS - Nordic Market Management System.
The purpose of creating a common Nordic market for aFRR and mFRR (manual frequency restoration) services is to increase socio-economic benefits at a regional level. This is achieved by enabling market participants to purchase aFRR and mFRR services across the entire Nordic synchronous area while respecting transmission system constraints.
- A capacity market is an essential tool for four TSOs (Statnett, Svenska kraftnät, Fingrid, Energinet) to secure a sufficient amount of balancing reserves.
- The purchase of a larger share of reserves at a lower price reduces the costs for transmission system operators.
- Improved frequency stability in the network.
- The efficient functioning of the market for aFRR/mFRR services allows transmission system operators in the region to have access to a sufficiently wide range of balancing services.
- Creating an overall framework for a shared market for aFRR/mFRR services for other countries in the future.
Who is our customer
Fifty AS is a joint venture of Svenska kraftnät and Statnett with the main goal to develop new market management systems and support systems for balancing of the Nordic power system.
Statnett and Svenska Kraftnät have cooperated on the development of a joint balancing and market system since 2015. There is a close cooperation with Fingrid and Energinet.

Damas MMS:E
Damas MMS:E is a comprehensive energy market management information system primarily designed and developed for the needs of transmission system operators, HVDC interconnectors and market operators operating in an open energy market environment.
Damas MMS:E fully supports market-related processes of transmission system operators and market operators in the following areas:
- System Services – Maintain the system balance using ancillary services efficiently and with minimum costs.
- Transmission Services – Gain income from congestion management and manage cross-border flows.
- Settlement Services – Evaluate and settle energy market transactions and make and receive payments.
NMMS Delivery
Each delivery of Damas MMS consists of three main activities: configuration, customization and integration into surrounding systems.
Configuration and Customization
One of the standout features of Damas MMS is its high configurability. Most system functions can be configured by analysts,
which shortens the information-sharing cycle and simplifies the overall delivery process. This flexibility allows us to quickly
adapt to sprint-based delivery for the customer, making it easy to prototype and demonstrate solutions, thereby facilitating feedback
and iterative improvements.
Integrations
Nordic MMS is integrated with numerous surrounding systems and solutions. This is achieved mainly through the ECP/EDX network, a standardized energy data exchange platform developed also by Unicorn Systems.
Damas MMS platform supports a wide range of data formats, mainly based on ENTSO-E EDI IEC/CIM standards, ensuring seamless integration.
Basic supported business processes:
• Master data management
• System configuration
• Administration of regulatory capacity requirements from four TSOs
• Administration of cross-zonal capacities (CZCs) and their valuation (inputs from RSC and NEMO)
• Receive bids for balancing capacity from BSPs
• Clearing (calling an external service provided by Optimeering)
• Post-clearing operations and distribution of results
• Settlement
• Cost-benefit analysis
• Basic reporting
• Comprehensive backup solution on the MS SharePoint platform
Product support:
• aFRR - automatic Frequency Restoration Reserve
• mFRR - manual Frequency Restoration Reserve
• FCR - Frequency Containment Reserve
Data interfaces:
• 4x TSOs: receiving requirements, providing results
• BSP: receiving bids, providing results
• RSC: receiving available CZCs, providing used CZCs
• NEMO: receiving spot market prices
• ENTSO-E transparency platform + Nordic transparency platform: providing results
Results of Nordic MMS Project
The project was successfully launched and already achieved several go-lives with different settings for different markets. The project meets the customer's needs and brings a lot of benefits to the Nordic region, such as a reduction of the cost for the Transmission System Operators.
A common aFRR CM corresponds to an economic surplus of 11.2 mills. EUR from December 8th, 2022, to March 24th, 2023, which means the average daily surplus only for the smaller aFRR Capacity Market is around 100,000 EUR.
