Energy Market Authority (EMA) has announced that its preliminary findings show that on 18 September, one of the power generating units at Sembcorp Cogen Pte Ltd (Sembcorp) tripped.

On 18 September 2018, there was an electricity supply disruption from 1.18am to 1.56am. About 146,500 customers were affected and supply was restored within 38 minutes.

EMA stated that the stability of the power system requires the electricity supply to constantly meet electricity demand. When a power generating unit trips, the other units in operation will increase their electricity supply automatically.

Subsequently, EMA said that one of the power generating units owned by Senoko Energy Pte Ltd (Senoko) tripped while it was ramping up additional supply. The tripping of the two power generating units resulted in insufficient electricity supply to meet demand.

In this case, the authority noted that the protection devices in the power system automatically disconnected electricity to about 146,500 consumers to rebalance the system.

To restore electricity supply, EMA said that it had instructed other standby power generating units, including unaffected units from Senoko and YTL PowerSeraya Pte Ltd, to provide additional electricity supply.

The restoration of electricity supply was done in a controlled manner to ensure the electricity system remained stable. As electricity generation increased, supply to consumers was progressively restored over 38 minutes.

Investigations are still ongoing and EMA noted that it is working with Sembcorp, Senoko and their equipment suppliers to establish why the units tripped.

“We will also look into additional measures that can be put in place to minimise the recurrence of such incidents,” it said.

“We thank the public for their patience and understanding for the inconvenience caused,” EMA added.

未优先考量本地雇员 一千家公司被列入观察名单

昨日,人力部长杨莉明在国会表示,本地有1000家公司因为聘雇时没优先考虑新加坡籍员工,在公平考量框架(,Fair Consideration Framework,FCF)下被列入黑名单。 她指出,自从公平考量框架观察名单在2016年推出以来,人力部已拒绝多达3千份就业准证申请,一些则是雇主本身取消。 与此同时,在上述观察名单企业,招聘的新加坡籍PMET(专业人士、经理、执行人员和技师),逾4千400人。 今年初,杨莉明称在新近更新的公平考量框架下,若有雇主在雇佣雇员时未公平考量或歧视本地雇主,将面对更严重惩处。 自年初更新以来,共23名雇主因不公平雇用方式受对付。 不过,仍有求职者反映,当局设立的“职业库”(Jobs Bank)“形同虚设”,一些雇主用迂回的方式,考量聘用外籍人士的案例仍存在。 就在两个月前,一家物流公司为外籍员工申请就业准证(EP,即Employment Pass),却谎称已先面试了两名本地人,结果面控。 先斩后奏?…
