Electricity in our daily lives

“Electricity is fundamental to the way we live. Without electricity the whole fabric of society would start to break down.”Les Moseley Centre for Disaster Management, UK

Page 3: sdfghsdfg

2

Electricity Supply ChainFuelis imported from overseas

GenerationPower stations convert fuel into electricity

TransmissionElectricity is transmitted through high voltage lines and converted to lower voltage at substations

Distribution

“We believe that electricity exists because the electric company keeps sending us bills for it, but we cannot figureout how it travels inside wires.”Dave Barry American Humourist

It is then distributed through lower voltage distribution lines

System OperationsMonitor the system and ensure that supply and demand of electricity remain in balance

Customer ServicesElectricity is enjoyed by 5.5 million people

Page 4: sdfghsdfg

Electricity is different from other commodities

• Electricity is fundamental to modern life • Electricity has no readily available substitute • Electricity cannot be stored economically• Electricity supply and demand must be kept in balance at all times or the

system will fail and there will be blackouts• Investments in electricity assets are costly and need to be continually

maintained• Electricity investments can take a decade to build and have lives of

several decades

Page 5: sdfghsdfg

Hong Kong’s Electricity Industry is Unique• Hong Kong is one of the most densely populated

cities in the world with 6,300 people per square km. Small disruptions to the power supply affect large numbers of people

• Hong Kong is 100% dependent on imported energy

• Hong Kong is an international finance centre with 50% of the population living or working above 15th

floor

Hong Kong’s Primary Energy Needs

• Fuel for electricity generation and electricity imports account for almost 70% of all energy consumed in Hong Kong

• Hong Kong’s total energy requirement is higher than that of Demark, New Zealand, Ireland or Peru

Page 7: sdfghsdfg

Energy Sources and their Characteristics

Natural gas/ LNG* Lowest-emitting fossil fuel

* Needs infrastructure to transport –pipeline or carrier

* Relatively recent technology

developments have increased demand

Renewable(eg wind, solar etc)* Emissions free

* Requires significant natural resources and landarea

* Inconsistent availability –requiring back-upgeneration from fossil-fuel

Coal* Abundant supply

* Comparatively lower cost

* Higher-emitting fossil fuel

Nuclear* Lower-emitting fuel than coal and gas

* High initial capital cost

* Low fuel cost

* Waste and decommissioning needcareful management

Oil* Relatively lower emissions

than coal but more than natural gas

* Comparatively higher cost

* Increasinglyscarce supply throughout the world

Global Energy ChallengeHow to provide energy necessary for social and economic development, yet avoid serious environmental impacts?

Page 9: sdfghsdfg

Reliability of Electricity Supply

• Hong Kong has one of the most reliable electricity systems in the world

Supply interruption frequency(Average number of interruptions per customer per year)

Supply interruption duration(Average minutes of interruptions per customer per year)

Fuel Diversification – Fundamental for Energy Security

• A balanced fuel mix is important for supply reliability, stable prices and environmental performance

Page 16: sdfghsdfg

15

CLP’s Current Environmental Initiatives

• Promoting Energy Conservation and Energy Efficiency

• Meeting 2010 emissions reduction targets set by Hong Kong – Guangdong governments

• Increasing use of ultra-low sulphur coal

• Installing additional emissions control equipment

• Bringing in liquefied natural gas (LNG)

• Renewable Energy Development

• Voluntary target of 5% of generating capacity from renewable energy sources by 2010

• Climate Vision 2050

• Comprehensive set of Initiatives and targets to reduce CO2 intensity

Page 17: sdfghsdfg

16

Energy Efficiency and Conservation

• Making our own operations energy efficient

• Electricity tariff designed to promote energy conservation

• Community-wide energy conservation programmes:

• Sharing expertise in energy efficiency and conservation with customers:

• Energy audits

• Promoting energy efficient equipment

Page 18: sdfghsdfg

17

Ultra Low Sulphur Coal

In 2006, CLP consumed ~10% of the world’s entire production of ultra low sulphur coal to meet 2/3 of its total coal requirement

Annual World Coal Production ~ 4,200 million tonnes

Ultra Low Sulphur Coal0.1 - 0.2% Sulphur

99%

Page 19: sdfghsdfg

18

Controlling Emissions from Castle Peak Power Station

• Essentially installing a 12-storey vacuum cleaner into an operating power station

• Some work can only take place during low demand season (i.e. winter)• After several years progress, phased completion starts in 2009• Upon completion, emissions of SO2 and NOx will reduce significantly

Page 20: sdfghsdfg

19

Natural Gas is Crucial to Reliable Electricity Supply and Clean Air• Black Point Power Station (2,500MW) is one

of the largest gas-fired power stations in the world, using natural gas for a decade

• Natural gas contributes 25% of Hong Kong’s electricity supply, addressing electricity needs of about 2 million people

• The existing gas supply to Black Point is from the Yacheng gas field near Hainan Island

• Yacheng gas field will deplete early next decade at the rate needed to meet 2010 emissions targets

• A safe, secure, reliable and robust long-term replacement is urgently needed to refuel Black Point and increase the use of natural gas

What is LNG?

LNG is natural gas cooled to -162oC

• Changes to a liquid, colorless, odorless and non-toxic

• Reduced to 1/600th of its former volume

• Transported at atmospheric pressure in insulated tanks on ships

• Natural gas is an abundant resource found all over the world and the cleanest fossil fuel available for power generation

Nuclear Energy

• Nuclear power offers the potential for very significant emissions reductions• Technical development could substantially address many of the current

concerns with nuclear power • Nuclear programmes of the future need not be judged in terms of the past

Opportunities• Little hydro and biomass resource

• Some reasonably good wind resource available but mainly at hilltops

Constraints• Country Park Ordinance

• Urban areas

• Hong Kong Aviation Height Restrictions

• Wild Animal Protection Areas

• Sites of Special Scientific Interest

• Gazetted Bathing Beaches

• Seawater Intake Points

• Residential and Commercial Premises

• Disneyland Resort Height Restrictions

One big challenge: lack of land resource

Meeting energy needs and having a better environment requires sustained and collective effort from every sector of the community

• We need to keep all energy options open – there is no single solution to the world’s energy and climate change challenges

• All countries are different – no single approach will work equally well in every region

• Long term stability, predictability and a clear energy policy will help encourage the investment needed for cleaner energy solutions

• Considerable time will be needed to reduce carbon emissions globally. A sense of urgency must be applied

• Energy conservation and efficiency is an area we can all contribute
