Teaming up with Chinachem Group to drive towards carbon neutrality goal

Riding on the successful collaboration with Chinachem Group (Chinachem) in 2019 to promote energy efficiency and decarbonisation, CLP Power continues to support Chinachem on its journey in pursuing carbon neutrality.

Chinachem Group set their sustainability goals for 2030 to further reduce their Scope 1 and 2 operational greenhouse gas (GHG) emissions by 51.8% by 2030. Chinachem collaborated with CLP Power in 2019 to transform the landmark Nina Tower into an operational and energy-efficient twin-towers complex by adopting smart and green technology.

In early 2023, CLPe signed a Build-Own-Operate-Transfer (BOOT) agreement with Chinachem to build Hong Kong’s first zero-carbon chiller system at Nina Tower. Under the 20-year agreement, CLPe will provide funding, design and engineering work to convert the existing air conditioning system into an energy-efficient water-cooled system. PlantPro, an intelligent AI management system, is used to control the chiller plants to collect and analyse data, performing real-time monitoring and adjustments to provide Nina Tower with the most energy-efficient air conditioning. The system is expected to reduce electricity consumption by over 50% compared with the existing system, equivalent to a reduction of 7,000 tonnes of carbon emission a year. The electricity consumed by the chiller plants will be matched by an equal amount of Green Electricity Certificates (GECs) linked to CLP Group's renewable energy projects in Mainland China.

Further, to make revolutionary change in the Hong Kong construction industry, CLP Power together with Chinachem, Gammon Construction Limited and Ampd Energy Limited promoted the use of Battery Energy Storage System (BESS) to the construction industry in Hong Kong. The pitch aims to replace traditional diesel generators operated on construction sites with BESS, and promote industry collaboration toward emission-free construction sites. BESS reduces carbon emissions by up to 85% annually as compared with traditional diesel generators. This successful collaboration on the application of BESS won the Association of Energy Engineers's prestigious Innovative Energy Project of the Year International Award 2022, a highly respected and prestigious competition in the construction industry.
