一 | (ECNS) -- Installed distributed photovoltaic (PV) capacity in Ningbo, Zhejiang Province, surpassed 10 gigawatts (10,000 MW) on Wednesday, making it the first city in China to reach the 10-GW milestone for distributed PV. As a major industrial and power-consuming city, Ningbo is accelerating its transition toward greener, low-carbon energy. Most of the city’s distributed PV systems are installed on rooftops, with industrial parks accounting for 84% of the total capacity. Mi Haiting, an official with the Ningbo Energy Big Data Management Center, said that based on an annual equivalent full-load generation time of 1,000 hours, the city’s distributed PV facilities can generate 10 billion kWh of clean electricity each year, reducing carbon dioxide emissions by around 5 million metric tons — equivalent to planting roughly 120 million trees. Mi noted that solar power generation can fluctuate sharply over short periods, creating new challenges such as reverse power flows and overloads in distribution networks, mismatches between power supply and demand during peak and off-peak hours, and more complex energy settlement within industrial parks. Feng Yibin, head of the Technical Innovation Office of State Grid Zhejiang Electric Power Co., Ltd., said the city has developed a county-level, multi-factor grid planning and simulation platform, supported by Ningbo’s Digital-Physical Hybrid Simulation Laboratory for the new-type power system, to address these challenges. A distributed PV operation monitoring application has also been launched locally.

This could raise the risk of a vehicle striking a pedestrian, which could result in severe injury or death, according to the NHTSA. The NHTSA's Office of Defects Investigation said that it's received two reports involving pedestrian injuries from Cruise vehicles. It's also identified two additional incidents from videos posted to public websites. The office said the total number of relevant pedestrian incidents is unknown. It opened an investigation on Monday. “Cruise’s safety record over 5 million miles continues to outperform comparable human drivers at a time when pedestrian injuries and deaths are at an all-time high," Cruise spokesperson Hannah Lindow said in a prepared statement. “Cruise communicates regularly with NHTSA and has consistently cooperated with each of NHTSA’s requests for information –– whether associated with an investigation or not –– and we plan to continue doing so.”The ODI said its investigation is being opened to help determine the scope and severity of the potential problem, including causal factors that may relate to ADS driving policies and performance around pedestrians, and to fully assess the potential safety risks. In August General Motors' Cruise unit agreed to cut its fleet of San Francisco robotaxis in half as authorities investigated two crashes in the city.The state Department of Motor Vehicles asked for the reduction at the time after a Cruise vehicle without a human driver collided with an unspecified emergency vehicle.。
