SC B2 is composed (October 2012) of 7 Advisory groups, 24 WG and 2 JWG.
The 3 first Advisory Groups are: Strategic (SAG), Customer (CAG) and Publication/Tutorial (PTAG) Advisory Groups who have in charge to Advise SC Chairman as far as Strategy, Customer satisfaction and publications are concerned.

The 4 Technical Advisory Groups (TAG) provides advice for assisting the Chairman in the definition of the directions to be followed by the SC:
  • Electrical performance (TAG04)
  • Tower/foundation/insulator (TAG05)
  • Mechanical behaviour (TAG06)
  • Asset management (TAG07)
Their responsibilities are:
  1. To coordinate WG within the scope of the Technical AG;
  2. To identify future direction of the technology in the technical area;
  3. To prepare new items of work and to submit them to CAG and SC Chairman;
  4. To coordinate TUTORIALS between different WG;
  5. To attract new Members and retain existing members;
