No more data quality problems in the energy industry
Energy companies lose hours to manual data errors, market communication bottlenecks, and fragmented systems. Tvimenning gives each type of data its own register, and makes them work together - from metering point to market.
All products speak the same language - from Elhub to market data.
Every module works on its own. Use ours, or keep the one you have.

How we build
We build in two stages. First a prototype we can demonstrate, then a version run against simulated market interfaces in STUBBMock services that simulate external systems with realistic behaviour and real data formats., our own test rigA setup that simulates the counterparty in an integration, so that behaviour can be exercised, failure cases included, before anything goes into production.. The label “Ready for the platform” is not a promise, it is a test result.
We show the modules long before they are finished, while there is still time to change them. Early input from people in the industry matters more to us than a polished launch.
The developers are our own, we have built together before, and the partners are hand-picked. We are a new company staffed with experienced people. Modern tooling makes writing the code faster, so our time goes into specification, testing and quality assurance. That is also why a rewrite is no longer the large project it used to be: we rewrite the code whenever that makes it safer and cheaper to run, most recently in July 2026, which leaves it no time to accumulate technical debtAccumulated costs of quick, short-term technological decisions - makes future development slower and more expensive..
The value therefore sits in the specification and the tests. The test rig we use for that is STUBBTvimenning's simulator platform for integration testing - we build mock environments of the counterparties your systems talk to, so they can be tested without touching production., and we sell it as a product: a customer can verify integrations and market processes before going into production. Our experience spans several parts of the energy sector, which is why the portfolio is broad: we know what an energy company needs.
The core is already standing. The integration layer SAMTYGDA shared integration layer to the modules, the surrounding systems and market hubs such as Elhub. has been in continuous customer operation for several years, and the management system is ISO 27001The international standard for information security management systems. It sets requirements for how security is governed, not for which products are used. certified. The registers SPIRAOne consolidated register for metering points, installations and assets - the source of truth the rest of the chain builds on. and RUNAOne register for the physical components - the whole lifetime, with traceable history and standardised designation., and the meter data engine SEFTAValidation, estimation, and editing with versioned time series, traceability, and export-ready data., are verified against simulated market interfaces. What gets finished after that, we would rather decide together with those who want to be part of it.
Why choose Tvimenning?
Deep domain expertise
Over 76 years of combined experience from the renewables and power sector, and we have worked on the customer side ourselves. We know Elhub and the NVE regulations, but also the working day of the people who use the systems. That is what we want to improve.
We write the industry glossary ourselves - 379 terms in four languages
Modules you can replace
The grid we work against stands for 50 to 200 years. Software does not, so the products are built as modules you can swap along the way without tearing out the core. No consultancy projects, no vendor lock-in.
Long-term partner
We operate what we deliver. The Røkte services are being shaped now, one at a time, and three of the four we have done before without setting them up as a service. If one of them is critical for you, this is the moment to say so.

The energy industry deserves better tools
We have worked in the Norwegian energy sector for over two decades. We know the frustration of systems that don't talk to each other, data that doesn't match, and integrations that are never finished.
Tvimenning was created because we knew there were better ways to do this - and we had the domain expertise to build them. Not generic platforms adapted after the fact, but software designed from the ground up for the Norwegian power sector.
“We build what we ourselves missed when we were on the customer side.”
