Can mACE function without the Common Grid Model and flow based capacity calculation?

Yes it can. CGM and a new capacity calculation is not a precondition. The mACE function will optimize the activations depending on bid price, system need and availible capacity. The availible capacity will in the first step be based on the NTCs that are used in the energy markets. MFRR can use the leftover capacity after Intra-day.

How and when will the ramping restrictions be changed?

The change to 15 minutes ISP will impact the DC ramping of the DC interconncetors both within and out of the Nordic synchronous area. New ramping restrictions will be negotiated as part of an updated Nordic synchronous area operational agreement.

Do the TSO's have plans for integrating the FCR-N and FCR-D markets on a Nordic level?

At the moment there are no formalized plans for integrating the FCR market on a Nordic level. However, the current development of Nordic common technical requirements for market participation in each country can be seen as an important step in a future, possible integration of the markets.

Have the Nordic TSOs assessed the economic benefits of the NBM? What is the foreseen improvement in frequency quality?

The main drivers for the Nordic Balancing Model are not financial, but required to keep a functional, secure and market-based power system with significant exchange of energy and balancing between TSOs. Large postivie benefits are based on analysis and implementation to uphold current benefit from nordic cooperation. There are large changes being implemented both for improving security of supply and implementation of european regulation.
Frequency quality is expected to be significantly improved with more available aFRR.

How is the role of aggregators taken into account in the new NBM road map? Are they regarded as stakeholders?

All relevant parties, including third party aggregators and IT-vendors are regarded as important stakeholders for the NBM-program. The consultations are open to all stakeholders which are welcome to join webinars and take an active part in the dialogue. Examples of changes that could affect aggregators are separation of the roles for BSP and BRP and automation of the mFRR balancing process.

Why does the operation change for the TSO's when we go to 15 min ISP? The TSO's are already balancing the grid in real time independent on the settlement perod.

Today all balancing decisions are taken by the TSO control room operator, with limited decision support. This approach is challenging today, and it is expected that the challenges will continue to grow. 15-minute resolution in energy trade makes the time available for making manual assessments much shorter. At the same time, the amount of information that needs to be assessed is increased. Changes in area imbalances, production, cross-border flows and mFRR resources, which today happens once from one hour to the next, will in the future happen four times per hour. With the timeline for the current balancing model in mind, it is clear that the operators must deal with several market time units in parallel, drastically increasing the information that has to be processed at any given time. In addition, there will be no room for making corrections between market time units, so any mistakes must be merged into the prognosis for the next market time unit. As there will most likely be no stable period between market time units that can act as reference, improved operator support for determining mutually regulated areas, balancing need and balance activation for the mutually regulated areas becomes critical. 

What kind of IT system, file format will be used?

There are many different IT systems involved in NBM. The file formats for interfaces between BSPs/BRPs and TSOs can vary. We acknowledge that the various parties need information in due time about protocols and formats for communication. The implementation guides for interfaces are targeted to be published by each TSO minimum 6 months prior to go-live of the respective changes.

Could you elaborate what you mean by "roadmap aims to be both ambitious and realistic". What is the risk of delays? How do ensure that the market is timely informed? The market was surprised when the TSOs informed that the transition to 15 minutes ISP would be significantly delayed.

NBM and the transition to 15 minutes time resolution is an extensive change and modification of IT platforms, operational procedures and legal regulations for the Nordic TSOs. This great challenge brings uncertainties to the roadmap planning. We expect valuable input from stakeholder in the consultation, contributing to a realistic roadmap from both a TSO and stakeholder perspective. The road map is considered realistic with a moderate level of uncertainty. The need for additional contingency (risk reserve) in the roadmap will be assessed throughout the consultation period and will be reflected in the finalized roadmap report. The ambition is to have a transparent dialogue througout this program, especially on milestones and changes relevant to stakeholders.

Are you going to establish a common Nordic timeline regarding national issues, for instance datahub's and changes in metering?

To some extent we will include national issues that have clear dependencies to NBM, but there are no plans to present a common Nordic timeline with all ongoing changes. For example local changes in metering is not something that will be included in the NBM road-map.
