Solar farm at Siu Ho Wan Sewage Treatment Works comes into operation (Date: 9 Dec 2016)
The solar farm at the Siu Ho Wan Sewage Treatment Works of the Drainage Services Department (DSD) came into operation on December 9. The largest of its kind in Hong Kong, the solar farm comprises over 4,200 polycrystalline photovoltaic panels with an installed generation capacity of 1,100 kilowatts. It can generate as much as 1.1 million kilowatt-hours of electricity annually.

Officiating at the "Energy Revives under the Sun - Hong Kong's Largest Solar Farm" commissioning ceremony, the Secretary for the Environment, Mr Wong Kam-sing, said that for combating climate change, the community must jointly practise the principles of "use less, waste less", including energy and water conservation, green commuting and consumption, with an aim of moving towards a low-carbon society. In addition to the promotion of energy saving for all and the use of natural gas for electricity generation to tie in with the carbon reduction targets, the Government is actively exploring opportunities for harnessing renewable energy sources. Despite the various constraints on developing renewable energy in Hong Kong, it is the right direction to incorporate the technologies of waste-to-energy and photovoltaics in the city's infrastructure facilities, such as sewerage treatment plants.

Another officiating guest, the Director of Drainage Services, Mr Edwin Tong, said that the DSD is committed to incorporating sustainable development elements into its facilities, and has made great efforts in promoting the application of renewable energy and energy conservation in particular. The solar farm at the Siu Ho Wan Sewage Treatment Works is one of the representative examples. The DSD has been using different types of renewable energy, such as solar energy and biogas, to supply a total of 32 million kilowatt-hours of energy a year, which is equivalent to about one tenth of the total energy demand of the department, he said. 

He added that the DSD will continue to enhance the total energy management strategy for its facilities and extend the application of renewable energy. To help develop Hong Kong into a low carbon and liveable city with high energy efficiency, the department will seize opportunities to widely adopt renewable energy in its new projects, as well as to implement effective emissions reduction measures to mitigate the impact of climate change.
     
The electricity generated by the solar farm at Siu Ho Wan Sewage Treatment Works will be fed through an internal power distribution network to various facilities inside the plant, including screening facilities, a workshop, an administration building, an ultra-violet disinfection system and sludge treatment facilities, which account for about 25 per cent of the current annual electricity consumption of the plant.
     
Other officiating guests at the ceremony included the Chairman of the Advisory Council of the Environment, Professor Paul Lam; the President of the Hong Kong Institution of Engineers, Mr Joseph Choi; and the Chairman of CLP Engineering Ltd, Mr Paul Poon.





The Director of Drainage Services, Mr Edwin Tong, delivered a welcome speech at the ceremony.
