Cainiao Network, (Cainiao), the logistics arm of Alibaba Group, has begun to utilize electricity generated with photovoltaic (PV) power generation systems on its bonded warehouses, which span over 100,000 square meters.

In a statement, Cainiao said this is located in Hangzhou and Ningbo in Zhejiang Province — the first warehouses to adopt renewable energy sources within the local bonded zone.

Cainiao noted that these solar panels can store 7.862 megawatts of energy with an annual power output of over 8 million kilowatts hour (kWh), or approximately the energy consumption of 3,000 households a year.

This initiative is estimated to reduce carbon emissions by 5,535 tons a year, equivalent to the yearly carbon intake of 700,000 trees.

"The PV power system on these warehouses generates close to 2,400 tons of coal per year. Installed on unused spaces such as the warehouse roof, the solar power system enables Cainiao to produce its own electricity to support warehouse operations while contributing towards the State Grid, China’s electric utility corporation, for broader usage," the Chinese logistics company said, adding that this safeguards the energy supply for the warehouses, and helps to reduce the cost of energy consumption, save energy, and reduce carbon emissions.

In the warehouse in Xiasha, Cainiao said the electrical output is then used to power energy-efficient operating systems. Energy-saving conveyor belts will also be able to automatically start or stop the motor based on the real-time parcel volume.

"The successful launch of Cainiao's first warehouse zone with a photovoltaic power generation system is just the beginning of sustainable measures that we have planned. We aim to build an eco-friendly global logistics network for our merchants and brands across the globe to reduce carbon footprints together," commented Sun Beibei, general manager, global supply chain, import business, Cainiao.

By 2023, Cainiao and its partner ecosystem are expected to install rooftop PV generation systems on Cainiao's bonded warehouses that span a total of 500,000 square meters.
