SAMTYGD
One integration layer between the modules, the systems and the market - in production since 2019
What is SAMTYGD?
SAMTYGDTvimenning platform for Elhub integration - handles all message types and processes to Elhub. is Tvimenning's shared integration layer. It is the glue between our modules - they do not read each other's databases, but talk to one another over unpublished APIs through SAMTYGD - and it is how customers reach the products, over published APIs. SAMTYGD can be bought on its own, and stands on its own in production today for ElhubNational hub for metering data and market processes in the Norwegian electricity market. metering data. Towards Elhub the platform covers all nine market rolesThe 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., and Tvimenning holds system approval in five of them - DDEThe Elhub market role that collects metering values from metering points and submits them to Elhub. Tvimenning is approved in this role., AG, DDMThe Elhub market role a grid company holds for submitting market messages to Elhub. Tvimenning is approved in this role., SLRThe Elhub market role for the supplier obliged to sell power to end users without a contract of their own. Tvimenning is approved in this role. and MDRThe Elhub market role a grid company holds for establishing and validating meter values. Tvimenning is approved in this role. - where all 71 message types are covered and tested. The core has been in active production since 2019. The integrations are written by people who have done this before at energy companies, with more than 99 years of integration experience between them. Experience from that side of the table is a requirement to become an integration developer here.
Built on a proven foundation
SAMTYGD is not built from scratch. The core is software that has been in active production since 2019 - Elhub-approved in 2020, further developed and modernised, and now launched as part of the Tvimenning platform.
- First service in production: 2019
- Elhub-approved: 2020
- Further developed and migrated to cloud-native architecture

Key features
Elhub gateway
Direct, system-approved integration with Elhub in five of nine market roles - DDE, AG, DDM, SLR and MDR - with all 71 message types in those roles covered and tested, and DDE and AG in production.
Message routing
Intelligent routing and formatting of messages based on type, recipient, and Elhub specifications - automated, with no manual follow-up.
Format handling
Automatic conversion between internal and BRSElhub’s process specifications. Each BRS describes one market process step by step - who sends what, when, and what happens when something fails.-compliant message formats. The right protocol - always.
Delivery tracking
Full traceability for all sent and received messages with acknowledgements, error handling, and audit log.
The glue between the modules
SPIRAOne consolidated register for metering points, installations and assets - the source of truth the rest of the chain builds on., SEFTAValidation, estimation, and editing with versioned time series, traceability, and export-ready data. and RUNAOne register for the physical components - the whole lifetime, with traceable history and standardised designation. do not read each other's databases. They talk to one another over unpublished APIs through SAMTYGD, and customers reach them over published APIs the same way. That is why one module can be replaced without the others noticing.
Connectors to the surrounding systems
The connectors to Elhub, Nord PoolNordic electricity exchange where power is traded in the wholesale market - the basis for electricity prices in Norway and the Nordic region. and the Norwegian Mapping Authority are in production. Volue ElsmartNorwegian AMI platform for collecting, validating and distributing metering data from smart electricity meters for grid companies. and Link Mobility are under development. Towards the NISThe system holding the grid's electrical topology - which components connect to which, and how. Not to be confused with the NIS2 directive, which is something else entirely. systems, RUNATvimenning's component register for electrical installations - providing structure and traceability for the components installations are built from. has a tested receiving APIApplication Programming Interface - standardised interface that allows two systems to communicate with each other. for network data, but for incoming messages only, and it has not been verified against Volue Netbas, openNIS or Trimble. The connector in SAMTYGD has not been started. If you need one of them first, the order can be influenced, at this stage customer needs drive the prioritisation.
End-user consent
A solar operator who needs to see a customer's consumption today needs an agreement, an integration and a project. Elhub has solved the trust part itself: the end user signs in with BankIDAn electronic ID issued through the banks, used both for signing in and for signatures with legal effect. at Elhub, picks which metering points the operator may see, and grants access there - no power-of-attorney forms, and no access routed through the operator's own system. We are building this flow into SAMTYGD. The aim is that the entry ticket should be a GLNA Global Location Number from GS1 - thirteen digits that uniquely identify a legal entity or a place. In the power market the GLN is a participant's identity. number and a return URL whitelisted at Elhub, and that the rest is the end user's own choices: how much is shared, which metering points, and for how long - consentThe end user's expressed permission for someone else to see or process information about them. In the power market it is the consent that gives a third party access to metering data. is time-bounded from day one, with three years as the default. The flow runs on the third-party role (AG), one of the five roles we hold system approval in. The functionality is under development, not in operation.
Stop asking
Most integrations with Elhub end up with a system that asks: has anything new arrived? Has anything arrived now? Each query costs nothing on its own, but it has to be written, operated and monitored, and it sits between the metering valueOne measurement from one metering point for one period of time. The building block all settlement rests on. and whoever needs it. We turn it around. SAMTYGD fetches from Elhub, and what is being developed now passes the values on to your system the moment they are fetched. You no longer ask, you receive. The functionality is under development, not in operation.
Messages you can read
Our customer deals with SAMTYGD, not with Elhub. So we do not pass the messages on as they arrive: the code values are translated into readable text, and what is not needed is stripped out. What remains is a Tvimenning standard with the same content - without anyone having to look up what a code means in order to understand what happened.
Results you can expect
- ✓7 years in active production at Norwegian energy companies
- ✓Monitored message delivery with acknowledgementThe receipt that says the message arrived. Its counterpart NACK says it was not accepted. Without one of them the sender knows nothing. tracking
- ✓Zero production deviations at launch - certification is already complete
- ✓Full traceability across all nine Elhub market roles
- ✓We take you through the actor approval towards Elhub - you do not face it alone
