Shared supplier qualification scheme for grid companies, TSOs and energy groups across the Nordics and Central Europe.
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.
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.
Balance Responsible Party - actor responsible for balancing production and consumption in its portfolio against the system operator.
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 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 third step in VEE - manual correction of metering values that cannot be resolved automatically, with full audit trail for all changes.
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.
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.
Finland's transmission system operator - owns and operates the Finnish high-voltage grid and runs the Finnish Datahub.
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.
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.
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.
The international standard for information security management systems. It sets requirements for how security is governed, not for which products are used.
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.
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.
Notice that something in operations deviates - planned maintenance, a fault or reduced availability. Should reach those affected before they notice it themselves.
Balance between power production and consumption in the grid at all times - system operator's core responsibility.
Predictions of future electricity production and consumption - essential for grid planning, balance settlement and market participation.
Industries with high electricity consumption per product unit - such as aluminum, silicon and fertilizer production - which receive special grid and market terms in Norway.
Geographic zone in the electricity market with a common spot price - Norway is divided into five price areas (NO1–NO5).
Settlement against an assumed consumption curve instead of actual hourly readings. The counterpart to hourly settlement.
Balance settlement and metering values at 15-minute resolution instead of hourly. Introduced in Elhub on 22 January 2024.
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.
Site Acceptance Test - testing of the equipment where it actually stands, after installation.
Turning metering data into money. Consumption and production per metering point become what each party owes or is owed.
Volue's established production-planning system for hydro, thermal and gas - being phased out in favour of Mesh.
The document listing which of ISO 27001's security controls an organisation actually applies - and justifying every one that has been excluded.
Hourly electricity price set in the Nordic power market the day before delivery - basis for variable electricity prices to end users.
A change in how things relate, not merely in a value - a metering point moves, a plant is split, a customer changes grid area.
Measurements of the same quantity repeated over time. The order and the timestamp are part of the data, not decoration.
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.
