Strengthening grid planning and energy transition
Through this process, the National Energy Commission aims to reinforce long-term planning of Chile’s power system, supporting the efficient, secure and timely development of transmission and distribution infrastructure. The initiative is particularly relevant in the context of rising renewable energy deployment, grid integration of solar PV and wind power, and the growing need for network reinforcements to ensure system reliability and facilitate future investment in clean energy.
