Governor Kim stated that the Gyeyangcheon maintenance project is a triple-benefit initiative that not only prevents floods but also addresses climate change and generates revenue, expressing his firm commitment to its implementation.


Governor Kim Dongyeon said, "First, the Gyeyangcheon maintenance project will require a budget of over 140 billion won, with only about 10 billion won coming from the national government and the remainder funded entirely by the province. Since it is essential for residents' safety, we will ensure its completion by 2029 as planned."


He continued, "Second, we will install solar panels on top of the retention basin here to create a solar power plant. Gyeonggi Province is the most proactive in responding to the climate crisis and promoting renewable energy. Third, since residents will participate as cooperative members and share in the profits generated here, you can see this as a triple-benefit initiative with positive intentions."


The Gyeyangcheon maintenance project is a flood prevention initiative for the section of Gyeyangcheon Stream stretching from Taeri in Gochon-eup to the Unyang-dong area in Gimpo City. The province plans to invest 142 billion won to create a 140,000-square-meter retention basin, construct a 0.8-kilometer-long embankment, and install one drainage gate and one bridge. Construction began on October 31, with completion targeted for October 2029.

When the water level of Gyeyangcheon rises due to typhoons or heavy rainfall, the project will temporarily store the excess water in the upstream retention basin and release it once the water level subsides, thereby preventing flood damage.


Since 2014, starting with the revision of the "Comprehensive Urban Stream Watershed Management Plan" by the Ministry of Land, Infrastructure and Transport, the province has laid the groundwork for the project by adjusting the basic river plan, revising the total project cost, conducting feasibility reassessments, and, in December 2023, announcing the river construction implementation plan and negotiating compensation.


Meanwhile, the province is implementing a profit-sharing public RE100 (solar power generation) model in this river maintenance project.

The project involves installing 565 solar panels in the Gyeyangcheon retention basin and creating an eco-friendly riverside park with walking trails and a futsal field below the basin. The power generation capacity will be approximately 10.8 MW, with an annual output of about 15 GWh, enough to supply 4,000 households of four people each for one year.



The province is planning a profit-sharing cooperative consortium with the participation of more than 50,000 residents, distributing the profits from power generation to participating residents. The expected annual revenue is 3.4 billion won, and the province anticipates not only financial returns from clean solar power but also carbon reduction and climate crisis response benefits.
