About Tvimenning
Tvimenning is a digital partner for the energy sector's digital transition. Our name captures something universal: the toughest challenges are solved by pairs - domain expertise and engineering craft, working as one. Proven in one of the world's most demanding energy markets. Applicable wherever the grid flows.
Why the renewable energy sector needs Tvimenning
The green transition demands more than technology.
Energy sector projects are long-term, capital-intensive and tightly coupled to critical societal infrastructure.
Digitalisation in this landscape demands more than off-the-shelf solutions.
It requires understanding of the domain, the regulatory framework, and the responsibility that comes with it.
We work with clients who need solutions that last. Solutions that hold up against time, change and reality.
More than a vendor
Power that endures
Norwegian grid operators have zero tolerance for errors in market communication. We built our tools to that standard. Many of the protocols we work with are international - AS4Open OASIS standard for secure message exchange over HTTP - the transport protocol required by Peppol, increasingly seen in European power-market messaging too., CIMCommon Information Model - IEC standard for semantic modeling of the electricity system, the basis for data exchange between TSOs across Europe., ECPEnergy Communication Platform - EU-standardised interface for secure data exchange between actors in the European power market. - others are national. The approach is the same. The domain expertise is always local.
Deep roots
The word tvimenning comes from a time when collaboration was a necessity, not a choice. To be tvimenning meant solving a task together - whether riding in company or sharing the same drinking bowl. For us, this is an image of professional integrity, craftsmanship and fellowship.
A tvimenning is kin - not only through blood, but through shared origin. We see our relationship with clients in the same light.
We share values, responsibility and ambitions. When we enter a project, we tie our own success to the outcomes created.
We build something together.
Trust is built over time. That is why we value long-term relationships, not short-term deliveries.
Tvimenning is about standing together when the horizon is far.
Be like water
"Empty your mind, be formless - like water. Pour water into a cup, it becomes the cup. Pour it into a pitcher, it becomes the pitcher. Pour it into a bowl, it becomes the bowl. Water can flow, or it can crash. Be like water, my friend."
- Bruce Lee, Pierre Berton Show, 1971
The energy sector has its own primal force. Data, integrations and power flow through critical infrastructure. We build the systems that harnessThe framework that wraps, drives, tests and constrains an AI agent. The model supplies the power; the harness decides where it goes. these forces - flexible enough to adapt, strong enough to hold.
Our values
Customer day first
We are here so our customers have peace of mind and control in their daily work. Every feature, every decision starts with one question: does this make the customer's day easier?
Depth over breadth
We specialise in one sector and know it inside out - the rules, the systems, the players. That understanding of the regulatory framework cannot be bought. It is built over time.
Simple solutions
The industry is complex enough already. Message flows and 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. cause headaches, and we are here to make sure it simply works. Clarity is not a bonus, it is part of the delivery.
Long-term partnerships
We do not want customers - we want partners. Relationships that last, where we come to know each other's strengths and weaknesses over time.
What makes us different
Nordic energy expertise
Years of combined energy experience from Nordic markets, regulation and operations. We know ElhubNational hub for metering data and market processes in the Norwegian electricity market. and the NVENorway's Directorate of Water Resources and Energy - regulates the electricity and water resources sectors. regulatory framework from the inside.
Software craftsmanship
Craft that works from day one, built on cloud-native architecture - scalable, maintainable and without shortcuts.
Customer-centric
We work closely with clients to understand the real challenges, and iterate based on feedback - not market assumptions.
Our story
How we grew from a single project to a Nordic supplier.
Code in production
The core of what is today SAMTYGDA shared integration layer to the modules, the surrounding systems and market hubs such as Elhub. enters active production at a Norwegian energy company. ElhubNational hub for metering data and market processes in the Norwegian electricity market. integration and message flow that actually works - not just on paper.
Elhub approval
SAMTYGDTvimenning platform for Elhub integration - handles all message types and processes to Elhub. holds Elhub system approval in five of 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. - Metered Data CollectorThe Elhub market role that collects metering values from metering points and submits them to Elhub. Tvimenning is approved in this role. (DDE), Third Party (AG), Grid Access Provider (DDMThe Elhub market role a grid company holds for submitting market messages to Elhub. Tvimenning is approved in this role.), Supplier of Last Resort (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 Metered Data Responsible (MDRThe Elhub market role a grid company holds for establishing and validating meter values. Tvimenning is approved in this role.) - with all 71 message types in those roles covered and tested. DDE and AG run in production.
Platform unified - four products launch
The products are unified under the Tvimenning platform. SAMTYGD is re-approved by Elhub under the new brand name. Four products launch - including STUBBMock services that simulate external systems with realistic behaviour and real data formats., which began as an internal testing tool for our own Elhub integrations and is now delivered as a product. From internal infrastructure to external delivery.
Growth and partnerships
We will operate critical energy data infrastructure for Norwegian energy companies, and build long-term partnerships with organisations that want more than just a product - they want a partner.
Based in Norway
Norwegian energy expertise does not sit in Oslo - it sits where power is produced. Just as our clients are spread across Norway, so are we. From Oslo to Mosjøen, and we grow deliberately in the regions.
Nordic focus
We have deep local knowledge of Nordic energy markets - an understanding of clients' daily reality that cannot be replaced by generic industry experience.
Built for long-term stewardship
Nordic heritage is about stewardship. We build solutions that last, with responsibility for what we deliver and respect for what we manage.
