Data Communications
The settlement data needs to be reported to eSett either by using electronic communications as specified in the Communication Guideline or by using the graphical user interface of the Online Service.
All reporting in the Nordic Imbalance Settlement Model is performed in accordance to the NBS Handbook and specifications are laid down in the market model and data format for data exchange can be found on www.ediel.org .
Communication principles
- A market party is expected to report NBS data according to their own role as specified in the Handbook and using the message structures defined in the NBS Business Requirement Specification Documents .
- eSett provides acknowledgements and settlement results to market parties as Data packages.
- On top of this there are several other possibilities for market parties to receive data regarding their own business and the whole market (please see the Market data available for customers section).
Market data available for customers
Open Data
Open data is a free and open service available for everyone (market participants, researchers, etc.) that contains imbalance settlement data and market participant structures related to the Nordic Imbalance Settlement.
Data packages
Market participants are able to order data packages of interest via Online Service.
Information of the available data packages and a full list divided into generic and specific data packages can be found below.
Furthermore, XML User Guide and XML examples for both generic and specific data packages are available here.
Online Service and Email notifications
eSett offers Online Service and Email notifications to help the customers to manage their settlement data and settlement results. Notifications are a way to notify Online Service users when certain business events occur. Users will receive notifications according to their assigned access rights. Notifications are delivered to users through email and/or via the Notifications views in Online service.
The following presentation provides fundamental information about notifications, including a comprehensive list of available notifications along with accompanying explanations.
Information Service
eSett Information Service (INFS) is a web service that provides settlement data for market participants and operates with request-response principle. INFS is a SOAP API where the requests and responses are enclosed in a SOAP envelope, and the data is in XML format.
Market participants that can use INFS data flows include: BRP, BSP, Datahub, DSO, PX Market Operator, Retailer and TSO. Generally, the provided data is market party specific that only the associated market participants are entitled to see.
INFS has been included in services provided by eSett since the go-live of eSett’s operations, and it will be upgraded to a modern RESTful web API in near future. The modernised eSett API will provide, but is not limited to, the same data flows that INFS currently provides.
The following document provides information needed to integrate with this interface.
