Power plant, Indonesia

Arun

Sumatra, Indonesia

184 MW

With a population of nearly 250 million and an economy that has grown at an average of 5.6 per cent a year over the last decade, Indonesia is hungry for power. To improve electrification and meet a demand that is expected to grow at 9-10 percent per annum in the coming years, much of the new capacity that is being added is in the form of large baseload coal-fired plant. However, building an optimum generating system that can also meet peak electricity demand is a challenge.

Arun - Sumatra, Indonesia

THE CHALLENGE

Meet a heavily fluctuating peak demand for short periods

Very large operating window required

Grid stability and reliability issues

Currently baseload plants must
be used also for peaking

Fast growing demand soon renders current capacity insufficient

WÄRTSILÄ'S SOLUTION

Wärtsilä 34SG combustion engines capable of daily starts/stops without any impact on maintenance

Multiple engine solution with higher efficiency than open cycle GT plants

Internal combustion engines with excellent ramp rates and able to reach full load in 10 minutes

Smart Power Generation plants
used for peaking & grid stability

Attractive delivery time, financial
and development services

BENEFIT

Lower lifecycle costs

Can follow load without reducing overall plant efficiency

Grid support

More efficient use of baseload plants

Customer can deliver power
faster and start earning on
electricity sales earlier
