| Much of the energy generation in the world today is through non-renewable
resources. The growth in demand for mobile and ICT services has also resulted in
an increase in energy consumption to operate our networks. Hence, it is important
that we take active measures to be energy efficient and to reduce our environmental
impact. |
| |
| Our main focus is on managing energy use within our network infrastructure (which
include telephone exchanges, mobile base stations and satellite earth stations), data
centres and building operations. Our initiatives in FY2014 included: |
| |
| • |
Overhauling 4 chillers and replacing 2 chillers under our optimisation and energy efficiency programme; |
| • |
Extension of the Performance Enhancement Lighting Management System to 7 telephone exchanges and 2 satellite earth stations; and |
| • |
Commissioning of 2 photovoltaic projects as part of our efforts to promote use of renewable and alternative energy. |
|
| |
We also achieved Green Mark certification and PUB
Water Efficiency Building Award for existing buildings at
our Serangoon North office premise after a major retrofitting exercise. |

| Energy use |
| Singtel’s total energy use and energy intensity in FY2014 were 1,274,390 GJ and 184 GJ/revenue (S$ million) respectively. This includes electricity use by our network infrastructure, data centres and owned and rented premises, as well as non-renewable and renewable fuel consumed. |

|
| Electricity use represents 97% of our total energy use and has remained constant even though business has grown. Our overall electricity use in FY2014 was 1,245,781 GJ, an increase of 0.4% from the previous year. The increase is due to the installation of more mobile base stations in FY2014 to cater to our growing customer base and needs. However, this is mitigated by a reduction in electricity use across our office premises and data centres due to energy efficiency measures that we have put in place. We achieved an electricity intensity of 180 GJ/revenue (S$ million), representing a decrease of 2.2% from the previous year. |
