Key task
1. Strengthen unified planning and improve the standard system
Distribution network overall planning action
Distribution network planning should be carried out in a unified manner, with a five-year cycle and a prospect of 10-15 years, or 20-30 years if necessary. It should be combined with near-thin and far-thick and far-far, and rolling revision should be made at the right time. We will make plans more transparent and release them by the people's governments at the same level after fully soliciting opinions from the public and relevant departments and units.
