EMA works closely with the industry and other government agencies to maximise solar deployment and mitigate challenges faced in harnessing solar energy.

Overview

With lots of sunshine in Singapore, solar energy is our most promising renewable energy source. Our goal is to achieve at least 2 gigawatt-peak (GWp) of installed solar capacity by 2030, meeting the annual electricity needs of around 350,000 households.

Facilitating Deployment

EMA collaborates with other government agencies and the industry to maximise solar deployment using innovative methods:

Rooftops

  • SolarNova programme is a Whole-of-Government effort to aggregate demand for solar PV systems across government agencies. This includes installing the systems on the rooftops of HDB flats and public sector buildings.

  • Factors such as sunlight intensity, cloud cover and shade could affect the output of solar. As the share of solar in our energy mix increases, fluctuations in solar output could affect the stability of the power grid.

Reservoirs and Offshore Spaces

  • With 122,000 solar panels spanning across a land area of about 45 football fields, the 60 megawatt-peak (MWp) Sembcorp Tengeh Floating Solar Farm is one of the world’s largest inland floating solar PV systems.

  • Floating solar PV systems could also be found at offshore spaces, such as Sunseap EDPR's 5 MWp solar farm at Woodlands. The solar farm is expected to produce estimated 6,022,500 kilo-watt hours (kWh) of energy per year.

Temporary Vacant Land

  • The SolarLand programme by JTC involves installing modular solar PV systems on temporary vacant land. These solar PV systems are currently found on Jurong Island and at Changi Business Park.

Buildings

  • Building Integrated Solar Photovoltaic (BIPV) refers to the seamless integration of solar PV systems into the design of buildings such as roofs, facades, and windows. They offer a sustainable and visually appealing solution for clean energy generation in buildings.

In addition, we regularly review and introduce policy improvements to facilitate the deployment of solar energy:

Intermittency Pricing Mechanism

  • The Intermittency Pricing Mechanism (IPM) allows for the price of generated electricity to be adjusted based on the real-time availability of intermittent generation sources such as solar.

  • Such adjustments will ensure that the costs of reserves and regulation charges to all generation sources are allocated fairly. This makes solar deployment a more sustainable way of power generation.

Solar Aggregator Model

  • In this model, solar aggregators like solar leasing companies will receive consolidated export payments and metering data from SP Group. This streamlines the administrative processes for payment and data management.

Solar Deployment in Master-sub Setup

  • EMA is actively addressing constraints faced by owners or landlords with buildings under a master-sub scheme.

  • For instance, we are exploring options to enable them to become contestable and be paid for the excess solar power that they sell to the grid. This empowers them to benefit from their solar installations and contribute to a more sustainable energy future.

  • Currently, there are physical work-around solutions (e.g. to connect solar PV systems directly to a substation or connect a solar PV’s main switchboard to consumer’s main switchboard before connecting to the grid), which may be feasible for some buildings. Please refer to the terms and conditions for such solutions here.

Nomination of third parties to receive direct payments from SP Group

  • This involves allowing third parties to receive direct payments from SP Group on behalf of solar companies and consumers who have solar installations. With this arrangement, they will find it administratively easier to have solar installations under the solar leasing model.

Allowing consumers to have multiple embedded generation units and leasing companies on their sites

  • The current system design of SP Group’s billing system only permits payments to a single leasing company. However, if enhancements can be implemented, consumers will have the flexibility to engage multiple lessors. This will enable them to explore different technology options on their sites; and/or lease them from different entities.

Overcoming Intermittency

As with any intermittent energy source, tapping on solar comes with its own set of challenges.

  • With limited land space, we have to carefully consider the land to be set aside for solar installations versus other competing uses like recreational activities on reservoirs.

  • Factors such as sunlight intensity, cloud cover and shade could affect the output of solar. As the share of solar in our energy mix increases, fluctuations in solar output could affect the stability of the power grid.

Mitigating solar intermittency is essential for several reasons:

  • A stable and reliable electricity supply is vital for meeting the energy demands of homes, businesses, and industries. Fluctuations in solar output can disrupt the balance between electricity supply and demand, causing disruptions and grid instability.
  • Smoothing out solar power’s intermittency enhances grid stability as it minimises voltage fluctuations, frequency deviations and improves overall power quality.
  • Reducing solar generation variability is vital for integrating renewable energy sources effectively. It enables better integration with other energy sources to create a more reliable and diverse energy mix.

Following an award of a S$6.2 million research grant to a consortium led by the National University of Singapore, EMA has successfully tested a Solar Forecasting Model that is able to anticipate the solar power output in advance and proactively address any solar intermittency.

In addition to the model, we are also using technologies like Energy Storage Systems to manage solar intermittency.
