30. Supervision Area • Composed mainly of electronic/electrical engineers and technicians.

31. Supervision Area • Composed mainly of electronic/electrical engineers and technicians. • Weak Computer knowledge among team members (no course graduation in the IT area).

32. Supervision Area • Composed mainly of electronic/electrical engineers and technicians. • Weak Computer knowledge among team members (no course graduation in the IT area). • Large gap between new and old employees, due to a large time without new hires.

33. Supervision Area • Composed mainly of electronic/electrical engineers and technicians. • Weak Computer knowledge among team members (no course graduation in the IT area) • Large gap between new and old employees, due to a large time without new hires. • Old concepts and techniques are very difficult to change.

34. Motivation • The amount of data has been growing exponentially.

35. Motivation • The amount of data has been growing exponentially. • Many of these data are not directly linked to real time.

36. Motivation • The amount of data has been growing exponentially. • Many of these data are not directly linked to real time. • Increasing number of data to be supervised versus selective users interest.

37. Motivation • The amount of data has been growing exponentially. • Many of these data are not directly linked to real time. • Increasing number of data to be supervised versus selective users interest. • Several of these data are alarmed for long time.

38. Motivation • The amount of data has been growing exponentially. • Many of these data are not directly linked to real time. • Increasing number of data to be supervised versus selective users interest. • Several of these data are alarmed for long time. • Disrupting the work of real time staff.

39. Motivation • The amount of data has been growing exponentially. • Many of these data are not directly linked to real time. • Increasing number of data to be supervised versus selective users interest. • Several of these data are alarmed for long time. • Disrupting the work of real time staff. • The maintenance staff is not informed of problems.

40. Motivation • The amount of data has been growing exponentially. • Many of these data are not directly linked to real time. • Increasing number of data to be supervised versus selective users interest. • Several of these data are alarmed for long time. • Disrupting the work of real time staff. • The maintenance staff is not informed of problems. • This leads the system to become discredited.

41. Motivation • Reduction of revenues led to reduction of employees on the long term (retirement and no new hires).

42. Motivation • Reduction of revenues led to reduction of employees on the long term (retirement and no new hires). • Telecontrol of substations became a priority in order to reduce Substations operators workforce.

43. Motivation • Reduction of revenues led to reduction of employees on the long term (retirement and no new hires). • Telecontrol of substations became a priority in order to reduce Substations operators workforce. • Higher availability of systems are required when telecontrol is used.
