The Business Times | Wednesday, June 19, 2024 | COMPANIES & MARKETS SP Group to design district cooling, heating system for Chengdu development By Hykel Quek hykelquek@sph.com.sg 5 SP GROUP announced on Tuesday (Jun 18) that it secured a bid to design, build, develop and operate a district cooling and heating system for the new International Sports Park City in Chengdu, China. The utilities group is expected to invest more than 200 million yuan (S$37.3 million) in the sustainable energy project under a 19- year service contract. The cooling and heating system, which will also be owned by SP Group, will begin its operations in 2025. International Sports Park City – an integrated development located in Chengdu’s Wuhou District – will benefit from greater energy efficiency of more than 30 per cent for cooling and more than 50 per cent for heating, SP Group said. This represents annual energy savings of 2,900 megawatt hours, and an abatement of 1,700 tonnes in carbon emissions. The project, with a cooling capacity of 9,800 refrigeration tonnes, will be SP Group’s largest district cooling system in Chengdu. “China’s commercial and industrial boom, coupled with greater sustainability ambitions, has resulted in a higher demand for clean energy and digital solutions that can contribute towards China’s urban transformation and decarbonisation goals,” said Michael Zhong, SP Group China managing director. The integrated development, International Sports Park City – an integrated development located in Chengdu’s Wuhou District – will benefit from greater energy efficiency of more than 30 per cent for cooling and more than 50 per cent for heating, says SP Group. PHOTO: SP GROUP which will span 278,000 square metres, is an addition to the utilities group’s expanding portfolio of district cooling and energy management projects in China. It already secured similar projects, including Raffles City Chongqing and Guangzhou Knowledge Tower, as well as “pioneered the concept of a cooling microgrid in China” at Chengdu’s Wuhou International Urban Design Centre, said the company. It also won the contract to upgrade the district cooling system in Shudu Center in Q3 2023. SP Group is the largest district cooling project operator in Southeast Asia and currently operates the world’s largest underground district cooling system located in Marina Bay, Singapore.

Shanghai-listed Jinko Power is one of the largest private solar players in China. It has two centralised control centres in Shanghai that operate 3.2GWp of solar installations across 20 provinces in China. Under the JV, Jinko Power and SP will commit to developing renewable energy projects in China with the aim of becoming a leading player in integrated sustainable energy solutions, and to meet the needs of customers and accelerate clean energy transformation in China. Last month, SP Group concluded two memoranda of understanding (MOUs) in China to explore collaboration opportunities in renewable energy, sustainable integrated energy solutions and combined cooling, heating and power projects. The MOUs were signed with Jiangsu Huadian Yizheng Gas Cogen Power, a subsidiary of state-owned China Huadian, and Chongqing Three Gorges Energy Investment, a wholly-owned unit of China Three Gorges Corporation. SP Group's China headquarters is in Shanghai; the group has three other o ces in Chengdu, Chongqing and Guangzhou. SP GROUP RENEWABLE ENERGY
