EU's energy regulator - coordinates national regulators and sets common rules for the power market.
The encryption algorithm protecting data at rest - on disk, in databases and in backups. Where TLS secures data in transit, AES secures data that is stored.
Actor that pools flexibility resources from end users and trades them in the energy market.
Advanced Metering Infrastructure - comprehensive system for two-way communication between smart meters and power suppliers' systems.
Stationary battery installations (BESS) that store electrical energy to balance production and consumption in the power system.
The structured list of what something is made of - which parts, how many, and how they fit together.
Balance Responsible Party - actor responsible for balancing production and consumption in its portfolio against the system operator.
EU directive on resilience of critical entities - sets requirements for protecting critical infrastructure against physical threats.
The common grid model - the assembled data set European TSOs agree on, built from each area's own model and used as the basis for capacity calculation and operational security analysis across borders.
ENTSO-E's European profile of CIM - the narrowed format TSOs actually use to exchange grid models across borders.
Common Information Model - IEC standard for semantic modeling of the electricity system, the basis for data exchange between TSOs across Europe.
The collection point that pulls metering values from many smart meters and passes them on to the collection system in batches.
Corporate Sustainability Reporting Directive - EU directive requiring detailed sustainability reporting from large companies starting 2024.
Reduction or shifting of electricity consumption in response to price signals or the system operator's request - an important flexibility resource.
The data processing agreement GDPR Article 28 requires between a controller and a processor - regulates what the vendor is allowed to do with personal data.
Distribution System Operator - grid company that operates the distribution network and is responsible for electricity supply to end users.
Energy Communication Platform - EU-standardised interface for secure data exchange between actors in the European power market.
The third step in VEE - manual correction of metering values that cannot be resolved automatically, with full audit trail for all changes.
Energy Data Exchange - ENTSO-E's platform for structured exchange of power system data between European TSOs, primarily network models and capacity data.
Company that sells electricity to end users - purchases power in the wholesale market and sells it to consumers.
Household or business connected to the electricity grid and consuming electrical power.
European Network of Transmission System Operators for Electricity - collaborative body for European TSOs coordinating joint grid operations and regulations.
The second step in VEE - calculation of missing or rejected metering values based on historical patterns, neighbouring meters or statistical models.
EU's classification system for sustainable economic activities - determines which investments can be labeled 'green'.
Factory Acceptance Test - testing of equipment at the supplier before it ships to site.
Actor that collects and activates flexibility resources from end users for participation in the balancing market.
Market where end users and aggregators can sell flexibility to grid operators and the system operator.
Three different file transfer protocols that are often confused. FTPS is FTP with security added; SFTP is something else entirely that inherited the name.
General Data Protection Regulation - EU's data protection regulation, applicable in Norway via the EEA Agreement.
Company that owns and operates electricity grids and is responsible for power supply to end users.
Global standards organisation known for barcodes, GTIN and GSRN - the standard behind unique metering point IDs in the electricity market.
Electronic certificate proving that one MWh of electricity was produced from renewable energy sources.
Head-End System - central system for collecting and managing data from smart meters in AMI networks.
Energy carrier produced by water electrolysis - "green" when electricity comes from renewable power. Key technology for zero-emission heavy transport and industrial decarbonisation.
The standard giving every part of a plant an unambiguous designation by function, location and product. The basis RDS builds on.
The individual grid model - one TSO's description of its own area, and the building block that is merged with the others into a common grid model.
The international standard for information security management systems. It sets requirements for how security is governed, not for which products are used.
Customer Information System - the core system at power suppliers and grid companies for customer management and billing.
Rules and framework that govern the functioning of the electricity market - covers pricing, settlement and competition.
Nominated electricity market operator - the European role that runs the day-ahead and intraday markets within the single market coupling. Nord Pool and EPEX SPOT are examples.
EU regulatory framework harmonising the operation and access to electricity grids across European countries.
EU directive on network and information security - imposes strict security requirements on critical infrastructure.
Nordic electricity exchange where power is traded in the wholesale market - the basis for electricity prices in Norway and the Nordic region.
Electricity generated by nuclear fission of uranium or plutonium - emission-free during operation, stable baseload, and an increasingly prominent part of the European energy debate.
Wind turbines located at sea - provides higher and more stable production than land-based wind power, but with higher installation costs.
Wind turbines located on land - the fastest-growing renewable source in the Nordics, subject to NVE licensing and Elhub reporting.
European network for e-invoicing and e-procurement - uses AS4 as its transport protocol. Norway is among the countries with mandatory e-invoicing via Peppol for the public sector.
Industries with high electricity consumption per product unit - such as aluminum, silicon and fertilizer production - which receive special grid and market terms in Norway.
Combined producer and consumer - typically a household or business with solar panels that both consumes and feeds electricity into the grid.
Balance settlement and metering values at 15-minute resolution instead of hourly. Introduced in Elhub on 22 January 2024.
Reference designation system per ISO/IEC 81346. Gives every component in a facility one unambiguous designation that holds for its whole life.
EU renewable energy directive (third revision) with a target of 42.5% renewable energy by 2030.
Site Acceptance Test - testing of the equipment where it actually stands, after installation.
The document listing which of ISO 27001's security controls an organisation actually applies - and justifying every one that has been excluded.
Measurements of the same quantity repeated over time. The order and the timestamp are part of the data, not decoration.
Transmission System Operator - responsible for operation and balance of the transmission grid at national level.
The first step in VEE - automated checks of metering data against technical and logical limits to detect obviously erroneous values.
Validation, Estimation, Editing - systematic process to ensure quality of raw metering data from electricity meters.
