MUARA TAWAR 5 – Indonesia 234 MW – KA13E2 Combined-Cycle Power Plant

PROJECT FEATURESPROJECT HIGHLIGHTS- This project involves extension of the existing power plant with a fifth block.

The new KA13E2 block adds an additional 234 MW to the current 1800 MW

plant, helping the country to cope with the current electricity crisis on the

Java/Bali grid.

- The Alstom-Marubeni consortium already built combined-cycle block 1 and gas

turbine peaking block 2 in 1995.

- Alstom has already been a key player in the Indonesian power generation

market since the 1960’s. It has supported the client PT PLN in meeting the

growing energy demand of the country through the construction of gas, coal

and hydro power plants.

CUSTOMER BENEFITS- High availability and reliability thanks to the KA13E2 proven technology

- Optimised base load through Plant Integrator™ methodology

- High operational flexibility to meet the booming demand for power

- An environmentally-responsible power solution with low emissions

The power plant is located in Muara Tawar,

35 km from Jakarta, on the northern coast of

Java Island, Indonesia.

The Muara Tawar project benefits from superior integration throughAlstom’s project management skills, EPC capabilities and state-of-the-artkey components.

Meeting Perusahan Listrik

Negara Limited’s requirements

Demand for power has grownconsiderably in Indonesia, stimulatedby economic recovery. This increasein demand, combined withdecreasing generation capacities inageing existing power plants, couldhave led to a deteriorating demand-supply balance. To avoid such asituation, an investment programmewas launched to develop the existingMuara Tawar power plant. Thisproject will help the country to faceits present growth in power demand,while protecting the environmentwith clean power solutions.

With its environmental and economic advantages, this plant is another example of Alstom capability

to deliver clean integrated power solutions.
