Black Point Power Station Additional Gas-Fired Generation Unit D1 Project

  • Large areas of glazing allow natural light to penetrate to all areas of the building and allows less reliance on lighting maintenance and replacement. Natural lighting also provides a healthier and more comfortable workspace for workers and staff in the facility.

  • A well-insulated and naturally lit turbine hall maximizes the facility’s long-term energy saving

  • Photovoltaic (PV) Panel Installation

  • Rainwater Harvesting System

  • Gas Turbine

  • Generator

CLP Power Hong Kong Limited (CLP Power) has always made sustained efforts in reducing carbon emission and improving the environment through optimising its power generation fuel mix. Located in the New Territories of Hong Kong, the Black Point Power Station is one of the world’s largest gas-fired combined-cycle power stations. In support of the Government’s plans for significant carbon intensity reduction by increasing the percentage of local gas-fired generation to around 50% of the total fuel mix in 2020, CLP Power is constructing an additional gas-fired generation unit with an advanced design at the Power Station.

The new unit serves as an expansion in the Black Point Power Station’s overall generation capacity and would feature a Combined Cycle Gas Turbine (CCGT) configuration which would give it an efficiency of around 60%, higher than that of the existing gas-fired units. This project will allow for the use of coal-fired generation to be reduced, contributing further towards meeting the Government’s carbon intensity reduction targets and air quality objectives.

Green Features

Site Aspects

  • More than 3,330m2 landscape areas provided
  • Minimised environmental impact during construction phase (e.g. noise, air quality, waste water, etc.)
  • Limited outdoor lighting and noise

Materials Aspects

  • Procured air-conditioning units fitted with refrigerant, insulation and fire-retardant materials that will not contribute to ozone depletion
  • Recycled over 60% of construction waste

Energy Use

  • Installed energy efficient lighting fixtures, lifts and air-conditioning systems
  • Installed over 140 photovoltaic panels on the turbine hall roof which contributes to more than 1.5% of the building’s energy use
  • Fitted with intelligent daylight control and an artificial light dimming system

Water Use

  • Adopted highly efficient irrigation technology which reduces fresh water consumption
  • Fitted with a rainwater tank for rainwater harvesting

Indoor Environmental Quality

  • Incorporates a high-quality plumbing system design that reduces the transmission of bacteria, viruses and odors
  • Installed high performance lighting based on illuminance and glare index
  • Provides amenities to enhance operation and maintenance

Innovations and Additions

  • Hosted education tours to the public regarding low emission gas-fired power generation and the sustainable features adopted in the power station
  • Adopted hard-paved concrete tiles at the construction site to minimise dust impact when construction vehicles passed through and to further minimise the use of water for wheel washing

Story

The Benefits of Gas-Fired Generation

Natural gas is a relatively clean fossil fuel. It emits far less sulphur dioxide (SO2) and respirable suspended particulates (RSP) during power generation compared to other fossil fuels. The emission of nitrogen oxides (NOx) from the new unit would also be substantially reduced compared to the gas-fired units currently being used at the Black Point Power Station.

Moreover, the use of coal-fired generation would be reduced when the new unit comes into operation. This would contribute further towards meeting the carbon intensity reduction targets as well as the Government’s air quality objectives.

Combined Cycle Gas Turbine (CCGT) Technology

CCGT technology is adopted in the eight gas-fired generation units currently being used at the Black Point Power Station. The new unit will be state-of-the-art and capable of achieving an efficiency of around 60%, higher than the existing gas units, and will further reduce emissions.

The most special feature of a CCGT is its combined cycle dual turbine design, consisting of a gas turbine and a steam turbine. First, natural gas is burned in the gas turbine to generate electricity. During the process, the heat exhausted from the gas turbine is captured and transported to heat up water in a boiler. As a result, steam is produced to drive the steam turbine for power generation. The combined cycle design allows for greater output without the use of additional fuel.

CCGT Power Generation Process

  1. The combusted natural gas turns the gas turbine, which then drives the generator.
  2. The spent gas, which is still very hot, is captured in Heat Recovery Steam Generator to heat up water to steam.
  3. The steam turbine drives to generate power.
  4. The two turbines drive the generator together, resulting in greater efficiency.
