Answer: Challenges for power transmission include integrating new, often remote, renewable energy sources like wind and solar, as well as maintaining the stability and security of a vast, interconnected grid. For power distribution, the challenges are more localized, such as managing the increasing complexity of a decentralized grid with more rooftop solar and electric vehicle charging, and ensuring grid resilience against extreme weather events. Both sectors require continuous innovation and the use of advanced equipment for maintenance and construction, which is exactly where Ningbo Changshi provides comprehensive solutions.
