Svein Knudsen, ABB 26 th of August 2014 ONS Clean Energy Power from Shore Energy efficient solutions with proven technology © ABB Month DD, YYYY | Slide 1

ABB in Norway An innovative technology company through 130 years § Develops and manufactures technology for power solutions § Energy efficient solutions through control and automation systems § § Focus on: § Oil & Gas, Power from shore § Renewable energy § Upgrade of power distribution grid systems § © ABB | Slide 2 Production - distribution - consumption Charging system for EV § Shore to ship power connections § Building automation

Technologies for Power from Shore Three alternatives Alternating Current (HVAC) with compensation Direct Current (HVDC) © ABB Month DD, YYYY | Slide 3 Cables Power system Onshore Power distribution offshore Cables Power grid Onshore Compensation ~ Power grid Onshore Power distribution offshore Cables = Converter Cablesl = ~ Converterr Power distribution offshore

HVAC or HVDC? Elements to be considered: § Distance from connection-point to consumer § Power to be transferred § Cost, Available Space «Rule of thumbs» for choice of solution: © ABB Month DD, YYYY | Slide 4 § Less than 50 km – normally AC § Between 50 -150 km – dependent upon several factors § More than 150 km – Normally DC

Increased energy efficiency with Power from Shore § PFS efficiency Approx 90 % § § § Offshore gasturbine efficiency § 25 -30 % § 35 -40 % with heat recovery Result § © ABB Month DD, YYYY | Slide 5 Higher energy efficiency with PFS

Power from Shore How to increase availability and reduce cost § Increase availability § Ensure that all critical sub-systems are duplicated (full redundancy) § © ABB Month DD, YYYY | Slide 6 Cooling , protection etc § For DC ; 2 block system (4 cables) § Cost reduction elements § Utilize industrial standards § Let the contractor suggest solutions based upon proven solutions
