China: Hitachi Energy has supplied two 110 kV, 63 MVA EconiQ™ power transformers to China’s largest grid operator the State Grid Corporation of China (SGCC).
The transformers are intended a visionary substation project underway in the Jiangsu province, on China’s east coast. This project is in line with SGCC and Hitachi Energy’s strategy of pushing the boundaries in deploying sustainable technologies.
“Our EconiQ™ transformers are advancing the electricity industry’s sustainability journey and we are proud to support SGCC in building their first ‘zero-carbon substation’,” said Bruno Melles, Managing Director for Hitachi Energy’s transformer business. “These highly efficient and bio-degradable ester-filled transformers come with several benefits including reduction of carbon footprint and enhanced safety for people and local ecosystems”.
EconiQ™ transformers are optimized based on specific sustainability requirements of our customers and Hitachi Energy’s technology domain expertise, using environmental Life Cycle Analysis methodology. They contribute to decarbonization, enhanced safety for people, protection of ecosystems and responsible use of resources across the transformer’s life cycle. The transformers are also manufactured using fossil free electricity at Hitachi Energy facilities further contributing to the overall reduction of their carbon footprint.
The SGCC energy saving, and eco-efficient substation is expected to save about 18,000 T of CO2 eq emissions over its lifetime.
The reduction of the transformers’ carbon footprint comes from a low loss design as well as from the use of natural ester biodegradable fluid as the insulating medium, the first of its kind at 110 kV for SGCC. The plants from which the natural ester fluid is produced absorb CO2 during their growth phase in a process known as biogenic carbon capture.
Jiangsu province has a long history of business and industry and a large population of over 84 million people. The 110 kV Gaoxiang (Qingshu) “zero carbon” substation is a demonstration project in Wuxi, one of the largest cities in the province, with over 7.4 million people and a key city in the Yangtze Delta commercial area.
