Glossary

Adaptive Case Management - approach for handling complex, unpredictable processes where knowledge workers direct the flow rather than following a predefined process diagram.

An infrastructure layer sitting between applications and AI models, handling authentication, logging, rate limiting and model selection.

Component that acts as entry point for API traffic - handles authentication, rate limiting, and routing to backend services.

Practice of managing API changes without breaking existing integrations - typically through URL versioning (/v1/, /v2/).

Linking of separate IT systems to exchange data and processes across organizational boundaries.

Open OASIS standard for secure message exchange over HTTP - the transport protocol required by Peppol, increasingly seen in European power-market messaging too.

Process where the difference between planned and actual power exchange is reconciled - essential for the power market to function.

Messages travel directly between two parties, without passing through a shared hub. The opposite of the centralised model Elhub is built on. Also called point-to-point.

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.

Software built specifically for one organisation - gives full control, but costs more to maintain than off-the-shelf solutions.

A continuous, ordered sequence of events the recipient subscribes to, rather than asking for them at fixed intervals.

Development practice where security is integrated throughout the CI/CD process from the start rather than added at the end.

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.

Energy Communication Platform - EU-standardised interface for secure data exchange between actors in the European power market.

Electronic Data Interchange - standardised electronic exchange of business documents between systems.

Nordic profile of the EDI EDIFACT standard - used for electronic message exchange in the Nordic power market via Elhub.

Electronic Data Interchange For Administration, Commerce and Transport - UN standard for electronic data exchange.

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.

Denmark's system operator for electricity and gas - operates the transmission network and runs DataHub Denmark for market data exchange.

Energy Trading and Risk Management - system for trading, portfolio management and risk analysis in the energy market.

Architecture principle where system components communicate via events rather than direct calls - increases loose coupling and scalability.

System for planning, assigning and following up work carried out in the field - meter changes, component installation and inspections.

Ability to change power consumption or production in response to price signals or system operator needs.

Metering data used to operate and plan the grid rather than to settle consumption.

A text-based Norwegian file format for exchanging metering values, in use in the power sector since long before Elhub.

Home Area Network - communication port on smart meters enabling end users to extract their own electricity data in real time.

Tvimenning’s EDI server for bilateral message exchange: receives, translates, routes and acknowledges messages between companies and marketplaces.

Property of operations where repeated execution yields the same result - critical for reliable message handling in distributed systems.

Management of IT infrastructure through machine-readable configuration files rather than manual processes.

JavaScript Object Notation - lightweight data format for data exchange between systems, standard in REST APIs.

Structured process for transferring know-how from one person, team or organisation to another - important in system handovers and new partnerships.

The nine roles Elhub divides the market into. The role says what a party does in a message exchange, not who the party is, and approval is granted per role.

Volue's newer, object-oriented data-handling system underpinning the Smart Power suite - the successor to SMG.

Management of metering point data in Elhub - covers registration, changes and deregistration of metering points.

Architecture or design principle where systems are built from independent, interchangeable components.

EDIFACT message format for exchange of metering data in the electricity market - used in Elhub to transmit hourly, daily and monthly values between market participants.

Nordic electricity exchange where power is traded in the wholesale market - the basis for electricity prices in Norway and the Nordic region.

Wind turbines located at sea - provides higher and more stable production than land-based wind power, but with higher installation costs.

Where our thinking comes from, with the sources named rather than presented as our own.

Simplified scheme for households and small businesses with solar panels up to 100 kW - the grid company handles settlement for surplus production.

An Elhub market role for suppliers sending BRS-NO-611 from a setup other than their DDQ role.

Mechanism that limits the number of API calls a client can make per time unit - protects services against overload and misuse.

Resource Description Framework - W3C standard for describing resources and their relationships as triples, the foundation for semantic web and CIM data exchange in the energy sector.

Pattern for handling temporary failures in distributed systems - automatic retry with exponential backoff.

The Ediel message family covering metering data and settlement. Where the E-messages handle customer and grid processes, the RSM messages carry the actual meter values.

Tvimenning platform for Elhub integration - handles all message types and processes to Elhub.

American audit standard (AICPA) for how a vendor handles customer data - the SOC 2 report is often what US and international enterprise buyers ask for instead of, or alongside, ISO 27001.

Single Sign-On - authentication mechanism allowing users to authenticate once and access multiple systems.

A change in how things relate, not merely in a value - a metering point moves, a plant is split, a customer changes grid area.

Process where an electricity customer changes their power supplier - handled through standardised messages via Elhub.

When the cost of switching supplier is so high that you stay for reasons other than the product being the best one. Not all lock-in is deliberate, but all lock-in must be known.

Norwegian EDI and message exchange platform, formerly Compello, which carried Ediel messages between energy market actors long before Elhub existed.
