What is ESS & how does it work in Singapore?

ESS enables the storage of solar energy for later use. The fast response nature of ESS will also help to maintain a reliable source of power supply when solar installations are affected by weather changes. These advantages are key enablers for Singapore to maximise solar as one of the four switches in Singapore’s Energy Story.

How much power does ESS have in Singapore?

Sign Up Througha partnership between EMA and SP Group, Singapore deployed its first utility-scale ESS at a substation this month that has a capacity of 2.4 megawatts, or the equivalent of powering more than 200 four-room HDB flats for a day, EMA said.

How will ESS help Singapore's solar energy system?

With ESS, the intermittency challenges of solar energy due to cloud cover and rain in Singapore's tropical climate can be mitigated, EMA said. The authority also noted that the "fast response nature" of ESS will help to maintain a reliable source of power supply when solar installations are affected by weather changes.

What does ESS stand for?

PHOTO: ENERGY MARKET AUTHORITY SINGAPORE - The country's first-ever utility-scale Energy Storage System (ESS) has been installed at a Woodlands substation, said the Energy Market Authority (EMA) on Thursday (Oct 22). The capacity of the ESS is equivalent to powering more than 200 four-room Housing Board (HDB) households for a day.

What is Singapore's first utility-scale ESS?

Singapore deployed its first utility-scale ESS at a substation this month, through a partnership between EMA and SP Group, has a capacity of 2.4MW/2.4MWh, which is equivalent to powering more than 200 four-room HDB households for a day.

How important are energy storage systems in Singapore?

These energy storage systems are "critical in supporting Singapore's target of at least 2 gigawatt-peak of solar deployment by 2030", as they help to integrate more solar energy into the power grid, said EMA chief executive Ngiam Shih Chun.
