Energy Storage Systems Test-bed

The Energy Market Authority (EMA) has established an Energy Storage Programme to develop technologies that will enhance the overall stability and resilience of Singapore's power system.

Energy Storage System Test-Bed

The Energy Storage System (ESS) Test-bed is one of the initiatives under the Energy Storage Programme. Singapore's current energy storage landscape is in its nascent stage. As this is one of the first ESS Test-bed, EMA and Singapore Power will jointly run the Test-bed to better understand the feasibility of deploying grid-level energy storage technologies locally.

Grid-level energy storage refers to technologies capable of storing electricity on a large scale within an electrical power grid. Such technologies may include lithium-ion batteries, redox flow batteries and flywheels. Energy storage could be used to enhance grid stability and support a higher penetration of intermittent renewable sources, such as solar PV into the grid.

The ESS Test-bed has three objectives: 

  • Evaluate the performance of these technologies, taking into consideration Singapore's hot and humid climate and highly urbanised environment;
  • Establish the standards and guidelines associated with the deployment of ESS; and
  • Establish the policy and regulation framework required to facilitate the introduction of ESS into the electricity market.

Update on the ESS Test-Bed

EMA awarded two Singapore-led consortiums to implement the ESS Test-bed. The Test-bed is expected to be implemented for three years at two substation locations in the north and north-eastern part of Singapore. These will have an aggregated capacity of 4.4 MWh, equivalent to powering more than 330 four-room HDB flats for a day. More information is available here.
