Advancing Singapore’s Energy Transition Towards a More Sustainable Future
25 Oct 2021
is a global existential threat and Singapore is doing its part to reduce
emissions for a more sustainable future. Our Long-Term Low-Emissions Development Strategy (LEDS)
aspires to halve emissions from its peak to 33 MtCO2
e (metric tonnes
of carbon dioxide equivalent) by 2050, with a view to achieving net zero as
soon as viable in the second half of the century.
2 The power sector has a
key part to play as it accounts for about 40% of Singapore’s carbon emissions
. We need to significantly
reduce the power sector’s emissions, while ensuring that the power system
remains secure, reliable and sustainable. Singapore is therefore harnessing four Switches – natural
gas, solar, regional power grids and low-carbon alternatives – to transform its
energy supply, while promoting energy efficiency to reduce demand.
Four Supply Switches for Power Sector Decarbonisation
Singapore transitions towards cleaner energy sources, reliable and sufficient
energy sources are needed to ensure supply reliability. Natural gas will continue
to be a dominant fuel for Singapore’s electricity generation even as we scale
up the other 3 Switches. EMA will continue to diversify our natural gas sources
and work with the power generation companies to improve the efficiency of their
remains the most promising renewable energy source in the near term for
Singapore. Today, over 500 megawatt-peak (MWp) of solar has been installed
and we are on track to achieving
our solar panel deployment target of at least 2 gigawatt-peak (GWp) by 2030
(equivalent to powering 350,000 households a year). Conventional rooftop solar
has been complemented with innovative ways of deploying solar
photovoltaic systems on spaces such as water bodies, temporary vacant land or
sheltered walkways, making Singapore one of the most solar dense cities in the
world. To manage the intermittent nature of solar and ensure grid resilience,
we are planning to deploy at least 200 megawatts (MW) of energy storage systems
(ESS) beyond 2025.
there are still limitations to the amount of solar energy that we can harness due
to Singapore’s limited land area. Even as we work towards achieving our 2030
solar target of 2GWp, it will constitute only around 3% of the country’s total electricity
demand in 2030.
6 To overcome our land constraints,
Singapore is tapping on regional power grids to access cleaner energy sources beyond
its borders. Regional power grids can help accelerate the development of renewable energy
projects in the region, bringing economic growth and increasing access to
renewable energy. Electricity imports will also help us to diversify our energy
sources away from natural gas and improve our energy resilience.
is planning to import up to 4 gigawatts (GW) of low-carbon electricity by 2035,
which is expected to make up around 30% of Singapore’s electricity supply in
2035. This will be done through a competitive Request for Proposal (RFP)
process. Steps will also be taken to maintain our energy security, such as
diversifying our import sources and ensuring back-up supply is in place to
mitigate supply disruptions.
pave the way for these electricity imports, EMA has been working with various
partners on electricity import trials. These trials will allow us to assess and
refine the technical and regulatory frameworks for importing electricity. They
include a trial to import 100MW of electricity from Peninsula Malaysia, as well
as a pilot to import 100MW of solar-generated electricity from Pulau Bulan, Indonesia.
Singapore is also a part of the Lao
PDR-Thailand-Malaysia-Singapore Power Integration Project (LTMS-PIP), which
facilitates cross-border power trade among the four countries.
is exploring emerging low-carbon technologies such as hydrogen and carbon
capture, utilisation and storage (CCUS) that can help reduce Singapore's carbon
footprint in the longer term. While such technologies are nascent, EMA is
taking active steps including investing in R&D through the Low-Carbon
Energy Research (LCER) Funding Initiative to improve the technical and economic
viability of implementing low-carbon technologies such as hydrogen and CCUS.
in geothermal technology have also opened up the opportunity for us to consider
the prospect of tapping on this energy source for power generation. For
instance, EMA is working closely with Nanyang Technological University, and various ministries
and agencies including the Ministry of Trade and Industry and the National
Climate Change Secretariat to conduct studies to determine
resource potential in Singapore.
Promoting Energy Efficiency to
transforming the way we produce energy, managing our energy demand is also key
to achieving a more sustainable future. With the economy recovering from the
pandemic and as energy demand grows with increasing electrification, demand
management will be a key pillar in supporting the energy transition. EMA will
continue to encourage energy efficiency in the industry and households, and is
concurrently developing other demand management initiatives. Together, everyone
will have to play their part by conserving energy and supporting the greener
energy transition for a more sustainable future.
