C1 Liaison Meeting

About this Event

The purpose of the meeting is to provide a high-level overview of the ongoing activities in CIGRE related to Study Committees C1 (Power Systems Development & Economics) led by UK Regular Member Charlotte Higgins. Technical Brochures published in the last year will be highlighted, along with a status update on all of the active Working Groups where the UK has an interest. You will also hear about the latest new work items approved by the Study Committees during the Paris e-session, and to provide feedback on possible future work items that could be proposed in the future.

Joining the meeting

Simply register from via the link below and you will be sent an email confirmation that will include the details of the CISCO WebEx login. Please keep this safe as you will need this on the day of the meeting.

C1 Study Committee Mission, Technology & Scope


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 synthesizing state-of-the-art practices and developing recommendations.


The scope of Study Committee C1 is to study Economics and system analysis methods for the development of power systems: methods and tools for steady state and dynamic analysis, planning issues and methods in various contexts, asset management strategies, in order to support electricity system planners worldwide to anticipate and successfully manage system changes to address the arising needs, opportunities and uncertainties while respecting multiple constraints.


Areas of attention include:-

System planning

  • Utilization of methods and tools for power system steady state and dynamic analysis in system planning and economic analyses.
  • Planning predicaments and methods in competitive and regulatory structures and with stakeholder involvement for public acceptance. Progress and new approaches in application of power system planning criteria and reliability (security, adequacy, resilience) 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 (grid codes).
  • System planning issues in newly industrialised and developing countries including metropolitan areas.

Asset management

  • Asset management strategies applied across a range of power system assets for the definition of optimal policies using e.g. total life cycle cost of ownership.

Business management

    • Impact on system development of new solutions and technologies in fields such as generation, demand side management (DSM), energy storage, “smart” and evolving distribution systems.
    • The impact of pricing and tariff methods for transmission services on system development and project priorities in the context of market design and grid ownership structures.

Interconnections – horizontal, vertical

  • Planning issues related to long distance transmission and international interconnections.
  • Interface and allocation issues in transmission and distribution planning, and delivery of multi-party/cross-jurisdiction projects.
