Lamma Power Station Extension
In the mid-1990s, HK Electric identified the need for building a new extension to its power station in Lamma to cope with the growth of Hong Kong as it entered the 21st Century. To minimise the environmental impacts of the new generating facilities, the Company decided to adopt the gas-fired combined cycle technology for the extension.
Located at a reclaimed site of 22-hectare south of the Lamma Power Station (LPS), the extension was planned to have six gas-fired combined cycle units with a total generating capacity of 1,800 MW. The first 335 MW gas-fired combined cycle unit was synchronised in July 2006 and started its commercial operation in October 2006, bringing the total installed capacity of Lamma Power Station to 3,736MW.
Natural gas is used as the primary fuel of the generating units in the extension. It is environmentally friendly as it produces minimal sulphur dioxide and respirable suspended particulates, less nitrogen oxides and carbon dioxide after combustion. The combined-cycle technology also has higher efficiency, i.e. produce more electricity with the same amount of heat.
In addition to using cleaner fuel, the LPS extension also features a variety of green measures in its design, construction and daily operations. To know more about how these measures and how natural gas is used to produce cleaner energy, please browse our brochure “Introducing Natural Gas”.
