The Group of International Comparison

of Transmission System Operation Practice

Since 1995 the international TSO comparison group is a group of electrical transmission system operators spanning Asia, Europe, South-Africa, South and North America. Its mission is to exchange information on their current and future operating practices for the purpose of benchmarking. An annual survey is undertaken to ascertain equivalent staffing requirements, best practices and/or performance measures in areas such as transmission system operations including generation scheduling and dispatching, electricity market operation, operations planning, settlements, information technology, training et cetera.

The results of the annual survey are an important basis for performance comparison and for improvement of operating practices. In some countries regulatory authorities would require this kind of information. Information is kept strictly confidential between members, but members are allowed to disclose agreed non attributable and market data for their own purpose.

Members of the Group discuss their experiences each year in one or two Workshops upon invitation of one of the participating companies. Membership of TSO is presently restricted to up to 30 companies/departments that qualify as an operator of a bulk transmission system.

TSO is managed by a Steering Committee consisting of 6 elected members and supported by KEMA.
