CIGRE develops technical knowledge using two methods: conferences and meetings, where papers are produced and discussed, and continuous work on technical subjects, conducted by its permanent Study Committees.

• The Biennial Session held in Paris every even numbered year is the most important CIGRE event: It brings together more than 2000 delegates from all the parts of the world and more than 300 papers covering all the fields of CIGRE are discussed.

• Symposia are usually held in odd numbered years, in different countries: attendance is smaller and these events focus on a limited number of topics.

• Other meetings are held at country level or at Region level.

• Presently 16 Study committees are active, each dealing with a technical field of the Power Industry. The work, carried out by Working groups and Task Forces, is coordinated by the Technical Committee of CIGRE. Altogether more than 1000 experts from all parts of the world are involved in these working bodies.
