CW, Red Dot to build utility-scale energy storage system in Singapore

CTBR Staff Writer Published 23 October 2017

CW Group and Red Dot Power consortia will establish the first utility-scale Energy Storage System (ESS) in Singapore.

The Energy Market Authority (EMA) and SP Group awarded the project to build the test-bed, for which the two consortia will receive $17.8m in grants.

The test-bed is expected to be operational for three years at two sub-stations in the north and northeastern part of Singapore, and have an aggregated capacity of 4.4 MWh, which is equivalent to powering more than 330 four-room HDB flats for a day.

The performance of ESS technologies, redox flow and lithium-ion batteries, will be evaluated under the hot and humid environment of Singapore.

Findings from the test-bed initiative will help Singapore in accelerating the use of ESS besides helping it in realizing its target of achieving 1GWp of solar by 2020.

The test-bed is also expected to help establish guidelines for grid connection and safety requirements for deployment of ESS.

Earlier, the EMA and the SP Group had launched a request for proposal to implement a utility-scale ESS test-bed.

EMA chief executive Ng Wai Choong said: “Insights from this test-bed would be useful for Singapore to learn how storage could enhance the stability of our grid, provide quick response capacity and improve operational flexibility.”

“We are also exploring how to couple energy storage with solar forecasting capabilities to enable greater deployment of solar in Singapore.”

SP Group chief executive officer Wong Kim Yin said: “SP Group is committed to helping Singapore save energy and cost.”

“We will adopt technology and solutions that would deliver savings. This project is a collaboration with EMA to assess how we may adopt storage to save costs.”
