Power from shore

All new developments on the Norwegian Continental Shelf need to conduct a power from shore assessment. This assessment include a technical feasibility assessment and abatement cost assessment. add energy has since 2002 assisted Norwegian Oil and Gas association, Norwegian Petroleum Directorate, individual operators and other stakeholders with power from shore assessments. We conduct studies for individual field developments and area evaluations. We estimate the emission reduction potential, CAPEX and OPEX and calculate the abatement cost (cost per CO2 mitigated). We also evaluate other impact effects of power from shore.

Methods for estimating direct hydrocarbon emissions from the NCS had not been updated for 20 years, and Norwegian Environment Agency needed to assess new methods to assure that correct numbers are reported.

What we did

add energy conducted the assessment in close co-operation with the industry by in-depth meetings with process and operational experts in the operating oil companies. The assessment included emission source mapping of 68 offshore installations operated by nine different companies.


  • 47 common sources were identified
  • BAT were proposed for all the sources
  • A basis for new improved estimation methods was proposed
