SINGAPORE – Sembcorp Industries has built a 285 megawatt-hour (MWh) energy storage system (ESS) facility on Jurong Island that it was appointed to build six months ago. The group on Friday said it is the largest such facility in South-east Asia.

Sembcorp expects the ESS to be accretive to earnings, though not material to the earnings per share and asset value per share of the group for the financial years ending December 2022 and December 2023.

The latest announcement comes after the group’s utility unit, Sembcorp Utilities, was appointed by the Energy Market Authority (EMA) in June to develop a facility with a contracted capacity of 200MW of power per hour.

That is enough capacity to meet the daily electrical needs of nearly 17,000 four-room Housing Board flats in a single discharge, Sembcorp said.

A megawatt hour is equivalent to 1,000 kilowatts (kW) of electricity generated per hour. An electric kettle, for instance, runs at about 1.5kW per hour.

“ESS is an essential technology to support solar deployment, and enhance grid reliability and energy supply security in Singapore, especially with the ongoing volatility in the global energy market,” Sembcorp said.

The ESS technology enhances grid resilience by actively managing mismatches between electricity supply and demand, according to information from EMA’s website.

It also addresses the issue of solar intermittency, which refers to less solar power being generated on, for instance, overcast or rainy days.

In a speech at the Singapore International Energy Week in October, Minister of State for Trade and Industry Low Yen Ling said that the ESS facility will create the need for more people trained in green jobs.

She said: “With the growth of ESS, the energy sector will be looking for ESS engineers, system designers and software developers, as well as those who can provide procurement, construction and project management services.”

With the Jurong Island facility online, Sembcorp’s battery storage portfolio stands at 709MWh in Singapore and Britain.

Sembcorp shares fell 1.47 per cent to close at $3.36. THE BUSINESS TIMES
