Berita Panas: Kenapa TNB beli tenaga dari luar


Kenapa perlu membeli tenaga dari luar sedang TNB mempunyai lebihan 10,000MW kuasa pada Grid Tenaga Negara. Mengikut laporan The Star online TNB membeli 180MW tenaga tambahan bagi menampung kestabilan Grid Tenaga Negara. Jadi ke mana menghilangnya 10,ooo MW tenaga yang dikatakan itu?

Petikan dari akhbar The Star Online:

PETALING JAYA: Tenaga Nasional Bhd (TNB) is buying power from Singapore-based PowerSeraya Ltd, a unit of YTL Power International Bhd, as a shutdown of Petroliam Nasional Bhd-owned gas production platforms for maintenance work made worse a dwindling gas supply situation.

Chief executive officer Datuk Seri Che Khalib Mohd Noh said in a reply to a StarBiz query that the purchase was made to ensure supply security.

“We're buying 180MW only, which represents 1.5% of total demand,” Che Khalib said.

According to a Singapore Business Times report, the utility firm's purchase, which was extended to June 15, marked the first ever cross-border commercial sale of power between the two countries.

The report said the purchase was made following an approach by TNB in April to Singapore's Energy Market Authority and the generating companies for electricity supply needed to tide over capacity shortages “for a few months”.

This was caused by natural gas feedstock shortages faced by TNB's power stations due to the maintenance shutdowns, which could further reduce by 30% in the May to June period.

Singapore Business Times said TNB initially looked to buy electricity for just a month but persistent gas supply issues had forced the utility firm to extend the purchase.

Analysts believe that the purchase was made in case the coal-fired plants, which together with the gas-fired plants made up the bulk of electricity generating capacity, tripped.

OSK Research Sdn Bhd research head Chris Eng said if this happened, there would be the purchase from SerayaPower to rely on.

He added that gas supply had been tight since April but supply issues would likely ease up this month.

PowerSeraya chief executive officer John Ng was quoted by the report as saying that the amount of electricity exported to TNB was “small” and would come from a designated oil-firing steam plant at a 3,800MW facility.

He declined to go into commercial details of the deal but expressed the view that “we hope it opens the doors for future exports and imports of electricity between the two countries on a longer term basis”.

Previous instances of cross-border electricity exports between the two were only made during emergency outages, although Singapore has sounded out the possibility of the island-republic's generating companies importing electricity in the medium term, as one way to diversify energy options.

Operationally, some 200MW of electricity could be transmitted through two 230kV submarine cables linking Malaysia's national power grid with Singapore's transmission network at Senoko.

Dan mengikut kenyataan akhbar yang dibuat oleh Ketua Menteri Pulau Pinang Lim Guan Eng

EPU forced Tenaga to buy electricity from an independent power producer (IPP), believed to be Genting Sanyen, at 14 sen per kilowatt hour (kWh) despite an existing offer of 12 sen/kWh then; other IPPs then were charging 16 sen/kWh. Tan Sri Ani even dubbed EPU as the "Economic Plundering Unit" for rising electricity tariffs, saying the powerful agency forced the national power company to sign lopsided purchase deals nearly 20 years ago where Tenaga must purchase power it does not need. This has resulted in Malaysia having the highest energy reserve margin in the world at 52.6% at 2010.

Jadi dimanakah 10,ooo MW tenaga lebihan yang didakwa ini? TNB perlu menerangkan dengan terperinci permasalahan ini adakah benar negara mempunyai lebihan tenaga atau kita sudah mengalami krisis tenaga.

  1. ak rasa bukan lebihan eletrik 10,000MW; tapi ada lebihan kapisiti mengurus elektrik; mcm kapasiti Rangkaian Grid Tenaga Malaysia sekarang lebih kurang 19,000 MW; tapi penggunaan maksimum dalam negara adalah 13,000 MW

    ----AK RASA KOMPLEKS GRID TENAGA NEGARA MCM //MODEM INTERNET//; RANGKAIAN UNTUK KUMPUL/EDAR ELELKTRIK SAHAJA; BUKAN MENJANA ELEKTRIK--------
