Hong Kong has launched a new solar farm built on restored landfill in Tseung Kwan O, that aims to cut carbon emissions by an amount equivalent to planting about 20,000 trees each year.Jointly developed by environmental services firm Veolia and developers Sun Hung Kai Properties (SHKP) and Citic Pacific, with government support, the facility at South East New Territories Landfill features around 1,850 solar panels spanning 140,000 square feet.It is also the largest solar power installation of its kind in the city.The farm will join the government’s feed-in tariff scheme, an initiative encouraging private-sector investment in renewable energy by allowing participants to sell excess solar or wind-generated power to utilities at premium rates.Completed in late 2025, it is expected to generate about 1.2 million kilowatt-hours of green electricity per year, which is enough to meet the needs of about 360 homes.The solar farm will cut carbon dioxide emissions by around 530 tonnes a year, equivalent to the CO2 absorption of about 20,000 trees.Although Chief Executive John Lee Ka-chiu did not attend the opening ceremony, he reaffirmed the government’s commitment to fostering sustainable development and attracting market investment for the city’s energy transition.
