(EnergyAsia, September 29) — Tuas Power Ltd, a wholly-owned subsidiary of Singapore’s Temasek Holdings, has increased its generation capacity from the current 1,935 MW to its full licensed capacity of 2,670 MW with the completion of Blocks 3 and 4 of its four-block combined cycle power plant (CCP) development.

The increased capacity is expected to improve Tuas Power’s generation market share. Block 3 has been operating since June while Block 4 came on stream in early September. Each has a generation capacity of 367.5 MW.


The two new gas-fired generation units (Blocks 3 and 4) are part of the four-block CCP which make up Stage II of the Tuas Power Station development. Constructed and developed by the consortium of Mitsubishi Heavy Industries Ltd and Mitsubishi Corp, the two new generation units were officially handed over to Tuas Power in a ceremony to mark the completion of the development project last week.


Lim How Teck, chairman of Tuas Power Ltd, said: “The completion of Blocks 3 and 4 marks the conclusion of the Tuas Power Station Stage II development. The addition of the two new blocks will enhance our operational and trading flexibility and this, in turn, will enable us to sharpen our strategies to meet the challenging demands of the electricity market in Singapore.


“More significantly, Blocks 3 and 4 will utilise an additional source of natural gas supply, under an agreement signed with Gas Supply Pte Ltd in 2004. This dual source enhances the security and stability of natural gas supply to Tuas Power Station and reduces the risk of interruption to Tuas Power’s operations in the event of any upstream gas supply disruption.”


Lim Kong Puay, Tuas Power’s president and CEO, said: “The addition of the two new blocks will increase Tuas Power’s utilisation of natural gas-fired CCPs in our operations. With the Singapore electricity market becoming intensely more challenging, the more fuel-efficient CCPs will enhance the company’s competitive position. The greater utilisation of ‘cleaner’ natural gas will also further improve Tuas Power Station’s environment-friendly operations.”


Tuas Power also extended the contract package for the service and maintenance of the gas turbines for Blocks 1 and 2 to the consortium of Mitsubishi Corp and Mitsubishi Heavy Industries for another six years.


Mr Lim said: “The plants at Tuas Power Station have recorded excellent operating performance since we began operations. This reinforces our confidence in the capabilities of Mitsubishi’s machines. The development of Blocks 3 and 4 brings together Mitsubishi’s distinguished record of engineering excellence and Tuas Power’s highly effective team. This strong partnership enabled the completion of the development project ahead of the contracted schedule, a critical factor for Tuas Power competing in the challenging electricity market. We look forward to a continued partnership with Mitsubishi in the service and maintenance of the CCP.”
