C1 System Development and Economics


To facilitate and promote the progress of engineering and the international exchange of information and knowledge in the field of system development and economics.  To add value to this information and knowledge by means of synthesising state of the art prac­tices and developing recommendations.


The scope of Study Committee C1 is to study economic and system analysis methods important for the development of power systems and to assist utilities to find the best solutions in various evolving, competitive and unbundled conditions in the context of the overall en­ergy supply system and with social and environmental considerations.

The main areas of attention are:

  • Methods and tools for power system static and dynamic analysis;
  • Planning predicaments and methods in competitive and regulatory structures.  Pro­gress and new approaches in application of power system planning criteria and reli­ability (security and adequacy) assessment;
  • Capacity enhancement by use of risk-based security assessment and advanced in­formation, communication and power-electronics technology for improving system stability and dynamic performance;
  • Future dependence, requirements and economy of ancillary services for frequency and voltage control and other system needs;
  • The impact of pricing and tariff methods for transmission services on system devel­opment;
  • Asset management strategies in the definition of optimal policies;
  • Planning issues related to long distance transmission and international interconnec­tions;
  • System planning issues in newly industrialised and developing countries;  and
  • Impact on system development of new solutions and technologies in fields such as generation and demand side management (DSM).


Each Study Committee oversees a number of Working Groups.
