CEO'S REPORT

| HK ELECTRIC INVESTMENTS
Natural gas was primarily sourced from Australia and Qatar.
Our supply of low-sulphur coal with lower ash content from
Indonesia, Russia and Australia played a role in improving our
environmental performance during the year. During selection
and throughout our engagement we aim to ensure that
our suppliers uphold our own standards for sustainability
including ethics, human and labour rights, health and safety,
and environmental protection.
A range of emissions reduction measures is in place at LPS
including flue gas desulphurisation plants and low-nitrogen-
oxide burner systems. In 2015 we outperformed the
emissions targets set by the government.
During the year, we worked with the government to
determine emissions allowances from 2020 onwards. From
2020, our target emissions levels will further decrease by
26% for SO
2
, 29% for NO
x
and 28% for RSP respectively.
Apart from increasing production of gas-fired and renewable
energy, we will continue to invest in emissions reduction
technology and manage our fuel supply to meet the
challenge.
GENERATING GREEN ENERGY FOR BLUE
SKIES
Renewable energy forms an important part of our
sustainability strategy. We utilise both solar and wind
energy for power generation on Lamma Island. In 2015 the
renewable energy we generated offset 1,530 tonnes of
carbon dioxide emissions.
LOW-EMISSION ENERGY PRODUCTION FOR
THE NEW GENERATION
We constantly review the environmental impact of our
generation activities. In 2015, natural gas and low-sulphur
coal remained our primary fuels with the proportion of gas-
fired power standing at about 34%.

Hong Kong has adopted a carbon intensity reduction
target of 50%-60% by 2020 compared with 2005.
To support this target we aim to provide 50% of our
electricity supply to the customers using natural gas by
this date.
Our upcoming L10 gas-fired combined cycle generating
unit will be central to meeting these natural gas-based
energy targets. Combined cycle generation technology
is one of the cleanest and most efficient ways in the
world to generate electricity from fossil fuels. The high
efficiency of the new L10 unit means that using the same
amount of fuel, more power can be generated at a lower
cost.
Equipped with a Selective Catalytic Reduction system
and state-of-the-art Dry Low NO
X
combustion system,
the new L10 turbine will further minimise NO
X
emissions
beyond the levels of the existing units.
