User Contribution Model


In consultation with the Norwegian Research Council (NRC), Sigma2 introduced a user contribution model in June 2018. This will align the policies for user contribution with other national research infrastructures and increase the funding base for national e-infrastructure.

HPC, Storage services and TSD services are subject to the contribution model. Cost for the resources will depend on the funding supporting the research project.


Four  price categories

The model introduces four different categories of contributors. 

  • Category A 
    Large projects with funding from the Norwegian Research Council of 15 MNOK or more or storage needs above 10 TiB, paying for operational expenses 
  • Category B
    Non-commercial projects needing Dedicated Resources, paying for capital and operational expenses
  • Category C
    Commercial research and industry which will pay the full cost price
  • Category 0
    Non-contributing projects which are smaller projects not in any of the above categories

 The principles setting the foundation for the contribution model are explained in detail in the user contribution model specifications listed in a table at the end.


Costs of the Services

The table reports the costs for the resources for the categories 0 and A. For these categories the allocation of the resources will be on a per period basis, and is subject to an evaluation of the Resource Allocation Committee

Prices and allocation mechanisms for the other categories can be found in the User Contribution model document listed in the table at the end.

Category Service Cost (NOK per unit)
CPU hours  0
A CPU hours 0.07 
0 and A Project Storage < 10TB 0
0 and A Project Storage > 10 TB 1090.0 per year
0 and A Sensitive Data CPU hours 0
0 and A  Sensitive Data Storage < 10 TB 0
0 and A Sensitive Data Storage > 10 TB 1000.0 per year
0 and A Sensitive Data Backup 400.0 per year


  • Only projects which applied for funding and got a grant after June 2018 will be subjected to the contribution model, except SSF and FORINFRA-projects for which the contribution model is applicable since January 2018

  • Invoicing for Storage (TB) and HPC (CPU hours) will be done yearly, covering the usage between the 1 October to the 30 September next year. Invoicing for TSD resources will be sent by the TSD administration.

  • Projects in Category A, such as SSF and FORINFRA-projects, can select one of the two  possible invoicing mechanism:

    • (i) contribute the total budgeted amount for e-infrastructure expenses in the budget (as specified in the approved budget with the RCN) 

    • (ii) contribute according to the resources spent every period (pay-as-you-go).
