Feedback was received from 4 respondents, viz. PowerSeraya Ltd, TuasPower Ltd, Senoko Power Ltd and SembCorp Cogen Pte Ltd.
After careful consideration of the feedback received, EMA finds that the arguments for the proposed modification is not sufficiently persuasive to warrant modification to the existing window. There has been, to date, no conclusive evidence of market manipulation. Moreover, the effectiveness of the recommended change in addressing the potential for market manipulation and to bring about more reflective prices has been questioned and no consensus has been reached. Anecdotal evidence from other jurisdictions as provided by respondents in fact appears to contradict the argument for shorter data-collection time windows.
In view of the lack of sufficient evidence supporting the need foramendment to the existing window, EMA has decided to retain the current window i.e. to use the forward fuel oil prices transacted or quoted in the relevant days from 10am to 6pm Singapore time for the purpose of vesting price calculation.
