On September 23, CNOOC Limited announced  that Qinhuangdao/Caofeidian onshore power project has commenced operation successfully.

This onshore power project is located in the mid-western Bohai Bay,  containing two parts, firstly the Qinhuangdao 32-6 and Caofeidian 11-1 oilfields onshore power project, and secondly the Qinhuangdao 32-6 facility capacity expansion project. The Qinhuangdao 32-6 oilfields are approximately 20 kilometres from the coast, with an average water depth of 19 meters. The Caofeidian 11-1 oilfields are approximately 30 kilometres from the coast, with an average water depth of 25 meters.

The onshore power project has built two onshore high voltage switching stations and two offshore electric power platforms, with a designed power transmission capacity of 200MW. It is positioned to provide electric power to Qinhuangdao 32-6 oilfields, Caofeidian 11-1 oilfields, and Caofeidian 6-4 oilfields. The Qinhuangdao 32-6 facility capacity expansion project has been constructed with two simple oil-water processing platforms both of which rely on the electricity supply of the onshore power project to scale up a holistic oil extraction and capacity expansion by taking advantage of the onshore power grid. It is estimated that the daily increase in oil production will reach the peak of about 8,100 barrels in 2023, an increase of nearly 20% over the current level.

After the running of the onshore power project, compared with self-generating electricity in the platform, the relevant oilfields are expected to save 85,900 tons of standard coal equivalent, reduce 4,000 tons of NOx emissions and 186,000 tons of CO2 emissions in peak years. It demonstrates remarkable energy saving and emission reduction effects, which marks a historic change in the power consumption mode of China’s offshore oilfield operations. It also signifies that the energy consumption structure of offshore oilfields has embarked on a fully-fledged implementation of low-carbon transformation.

Wang Dongjin, Chairman of CNOOC Limited, said, "The onshore power project is a vigorous measure for the company to practice the concept of sustainable development and improve our capability of low-carbon operation. The company will take this as an important starting point, make every effort to promote increase in reserves and production, and demonstrate greater deeds in the implementation of the 'carbon peak and carbon neutrality' goal."
