What and why
Elhub is a central IT system that from February 2019 made the Norwegian electricity market more efficient. The electric power industry has over time become more digital and, in this connection, NVE (Norwegian Water Resources and Energy Directorate) decided that Statnett should develop Elhub.
What is Elhub?
Elhub is a neutral datahub that handles all metering data and market processes in the Norwegian electricity market. Through standarized interfaces for message exchange, all market parties relate to one party. Elhub receives and processes incoming messages and generates messages in return to the submitter and relevant parties. In accordance with several validation rules, market parties receive information within a short time about, for example, completed supplier changes, updates in basic data and metering values for production and consumption in Norway.
What does Elhub do?
Elhub has two main functions.
Distribution of metering values and calculation of the basis for balance settlement:
In Norway smart metering has been rolled out to 97 % of all metering points. The grid companies have the task of submitting all metering values for electricity consumption electricity production and exchange to Elhub by 7:00 am, the following morning. Elhub forwards the metering values to relevant balance suppliers, third parties and end users by 9:00 am, the same morning. In this process Elhub also profiles the consumption for non-hourly metering values.
Elhub daily calculates the basis for the balance settlement, which is the financial settlement in the regulatory power market, and reports this to eSett. The individual grid company is responsible for the data quality of the metering values, but Elhub provides the necessary aggregations and reports values in accordance with deadlines in eSett.
Elhub does reconciliation settlement for all metering points and conducts financial clearing between the market parties.
Elhub has also been given the responsibility for reporting consumption and production to NECS, which is Statnett’s register for el certificates and guarantees of origin. Production is reported daily, while consumption subject to quotas is reported quarterly.
Processing of market processes:
Market processes, such as supplier changes, move-in and -out as well as updates of basic data are sent to Elhub by the parties in the electricity market. Elhub has the task of verifying and responding to the messages as well as forwarding correct information to affected market parties.
Efficient distribution of metering values, with higher quality. The introduction of Elhub has contributed to the efficient distribution and measuring of metering values with high quality and utilization of the technological potential that lies in AMS (Advanced Measurement and Management Systems), both for grid owners, balance suppliers and end users.
Efficient settlement. Elhub calculates the basis for balance settlement, in one place and in the same way, independently of the grid owners.
Efficient management of marketing processes. There has been both time and cost savings as a result of centralizing a number of tasks in Elhub, for which the market parties have previously been responsible for. Business processes, such as supplier changes, have become easier. Elhub is, among other things, responsible for reminders and follow-up of processes that have previously been performed by each balance supplier. Market processes are carried out faster and with higher quality as they are more automated.
Lower threshold for new parties. With Elhub, each party has one interface to interact with. Third parties have one place to retrieve data from.
Increased neutrality. All parties are treated equally and have access to data on the same terms
Easier further development of the electricity market. Changes are made in one place. Elhub is designed for a supplier-centric market model and Nordic harmonization of the retail market.
Increased privacy and security. Elhub has a high level of built-in security. All messages are encrypted and access to data is restricted.
