CIGRE > Grids and Flexibility

Knowledge Programme > Grids and Flexibility

CIGRE is a world leader, we offer a scope of work covering the end to end power system. With over 4000 experts collaborating in our knowledge development programme, our electricity work on the energy transition is as global as it is comprehensive.

A key part of this work is around grids and microgrids integration and is enabled by our international study committees and working groups.

These groups involve experts from all over the world and the work they produce is renowned as a practical, world class, technical resource.
