Back-Up Power For Mass Transit

Wärtsilä will deliver a 100 MW Smart Power Generation plant to PT Indonesia Power, a subsidiary of PT PLN (Persero).

The Senayan Diesel Power Plant project will be used to provide back-up electrical energy designed to ensure the reliability and availability of power to Jakarta’s new mass rapid transport system that is currently under construction. The order with Wärtsilä was booked in December 2017.

The new plant will operate on six Wärtsilä 46 engines and is expected to be operational in early 2019. The engine has a bore and stroke of 460 X 580 mm and has a cylinder output of 1200 kW.

Critical to the selection of the Wärtsilä solution was the fast start up and ramp up time of the engines, the company said. In the case of a failure to the existing power supply, the mass transport system would be immediately adversely affected. Should this happen, the Wärtsilä Smart Power Generation solution will be able to restore full power within minutes, whereas a conventional power plant would not be capable of such a rapid reaction time, the company said.

The new plant is being built by a consortium of Wärtsilä and PT PP (Persero) Tbk, the Indonesian construction engineering company. The consortium will deliver a turnkey facility, with Wärtsilä leading the consortium and providing the main equipment and PT PP handling the civil and installation work.

“Fast starting flexibility and reliability were the prime criteria for this important project, and Wärtsilä has proven its capability to meet these needs. Furthermore, the heat rate of our engines is superior, and the total value proposition that we were able to present has once again given us the edge over the competition,” said Frederic Carron, Regional Director, South East Asia & Australia.

Indonesia Power has gained positive experience with the Wärtsilä generating equipment from its Bali Pesanggaran project, which also operates on Wärtsilä engines.
