Shared supplier qualification scheme for grid companies, TSOs and energy groups across the Nordics and Central Europe.
The receipt that says the message arrived. Its counterpart NACK says it was not accepted. Without one of them the sender knows nothing.
Organisational psychologist at Wharton. 'Give and Take' shows that the people who give most end up both at the top and at the bottom, and the difference between them is worth understanding.
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.
Services that keep the power system stable - frequency control, voltage regulation and short-circuit power - purchased by Statnett from producers and consumers.
Process where the difference between planned and actual power exchange is reconciled - essential for the power market to function.
Financial settlement between BRPs and the system operator for energy imbalances in a given period.
Power that Statnett buys and sells in real-time to maintain system frequency stability at 50 Hz.
An electronic ID issued through the banks, used both for signing in and for signatures with legal effect.
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.
The structured list of what something is made of - which parts, how many, and how they fit together.
Revenue arising when capacity limitations in power transmission between price areas exist - accrues to the system operator.
Business Process Outsourcing - a company takes over responsibility for running an entire business process for others, not merely the system it runs in.
Researcher at the University of Houston. Vulnerability is not weakness, but uncertainty, risk and exposure without a guaranteed outcome. Without it there is no trust.
Balance Responsible Party - actor responsible for balancing production and consumption in its portfolio against the system operator.
Martial artist and philosopher - "Be Water" as a metaphor for adaptability, precision and continuous improvement.
Digital certificate issued to a company for secure machine-to-machine authentication - required for access to Elhub's API in Norway.
A replaceable part inside a fixed asset. It has its own age, its own history and its own service life - independent of the asset it sits in.
The collection point that pulls metering values from many smart meters and passes them on to the collection system in batches.
Measures and processes for managing situations where demand for grid capacity exceeds supply - between bidding zones or within the distribution network.
The physical or logical point in the electricity network where responsibility for energy transfers from the grid company to the electricity supplier or end customer.
The 18-digit identifier that uniquely designates a metering point in the power market.
Nordic profile of the EDI EDIFACT standard - used for electronic message exchange in the Nordic power market via Elhub.
The six characters in UTILMD, INVOIC and CONTRL are not abbreviations someone invented locally. Each message type is its own standard in the UN EDIFACT directory, and the name is a six-character mnemonic.
The third step in VEE - manual correction of metering values that cannot be resolved automatically, with full audit trail for all changes.
Tradeable certificate proving that one MWh of renewable electricity has been produced and delivered to the grid.
Company that sells electricity to end users - purchases power in the wholesale market and sells it to consumers.
Sweden's planned central system for metering data and market processes. Legislated, but not in operation.
Household or business connected to the electricity grid and consuming electrical power.
Proactive role at DSOs (such as Lnett, Elvia and Tensio) acting as advisor and liaison between the grid company and customers - mapping future capacity needs and optimising grid capacity through dialogue with property developers and municipalities.
Collective term for all forms of digital data related to the production, distribution, and consumption of energy.
The company performing imbalance settlement for balance responsible parties across the Nordics, jointly owned by the four transmission system operators.
The second step in VEE - calculation of missing or rejected metering values based on historical patterns, neighbouring meters or statistical models.
Factory Acceptance Test - testing of equipment at the supplier before it ships to site.
Physical equipment owned and used over time - transformer, cable, breaker. It has both a technical and an accounting side, and the two rarely agree.
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.
A unique id that follows a component for its entire lifetime, across every system it appears in. The technical term for it is UUID.
Packet-switched mobile data standard (2.5G) used for remote reading of electricity meters.
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.
Global Service Relation Number - the unique 18-digit identifier for each metering point in Elhub, based on the GS1 standard.
Electronic certificate proving that one MWh of electricity was produced from renewable energy sources.
The framework that wraps, drives, tests and constrains an AI agent. The model supplies the power; the harness decides where it goes.
Energy carrier produced by water electrolysis - "green" when electricity comes from renewable power. Key technology for zero-emission heavy transport and industrial decarbonisation.
Electricity produced from the potential energy of falling water - Norway's dominant energy source (~90% of production) with a unique ability to ramp up and down quickly.
The standard giving every part of a plant an unambiguous designation by function, location and product. The basis RDS builds on.
Swedish software company, founded in Linköping in 1983. Known for ERP and maintenance solutions aimed at asset-heavy organisations, and widely used among Nordic energy and industrial companies.
The international standard for information security management systems. It sets requirements for how security is governed, not for which products are used.
American software developer, born 1961. Created Extreme Programming, popularised test-driven development and wrote JUnit. "Make it work, make it right, make it fast" is his, and that is the order we follow.
The authoritative source data in a System of Record (Master) - data owned, maintained and edited in one place, from which all other systems retrieve copies.
Volue's newer, object-oriented data-handling system underpinning the Smart Power suite - the successor to SMG.
The fundamental unit in Elhub - the unique point in the electricity network where energy is measured and settled, identified by an 18-digit GSRN number.
One measurement from one metering point for one period of time. The building block all settlement rests on.
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.
LPWAN communication standard optimised for low power consumption and good indoor coverage - replacing GPRS in new AMS infrastructure.
Nordic electricity exchange where power is traded in the wholesale market - the basis for electricity prices in Norway and the Nordic region.
Cooperation body for Nordic energy regulators - coordinates regulation of the shared Nordic electricity market.
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.
