ALSTOM signs major modernisation contract for Rifaa II
power plant, Bahrain

The single-cycle power plant consists of six type GT13D2 gas
turbines operating on fuel gas. The plant is over 20 years old
and while it continues to operate reliably, it requires
significant investment to ensure its long-term performance and
competitiveness. The modernisation project will not only
restore gas turbine output and efficiency lost due to the
effects of ageing, but will vastly improve overall plant
performance and meet the highest environmental standards.
Customer maintenance costs will also be significantly
reduced.

The scope of the contract includes the replacement of
existing gas turbine single burners with ALSTOMs
well-proven EV burner technology to significantly reduce NOx
emissions.

The plants gas turbines will be upgraded to GT13DM
comprising new blades, vanes and vane carriers. The benefits of
the upgrade include the extension of major overhaul intervals
from 3 to every 4 years, increased efficiency and power output,
and reduced life-cycle costs of the turbines.

Instrumentation and control and electrical systems will also
be modernised, incorporating Turbopack 3000, ALSTOMs
modular service solution for the upgrade and modernisation of
electrical systems.

The plant will be upgraded between November 2006 and 2009
during scheduled major overhauls of the gas turbines.

Hans-Peter Meer, Senior Vice President, Power Service
commented, We are delighted to be chosen by MEW for this
project which will bring major environmental benefits and give
the Rifaa II plant a second life in preparation for its
important long-term role in Bahrains growing power
generation market. This success is based on our extensive
upgrade and modernisation experience and our competence in
engineering integrated plant service solutions that support our
customers competitiveness".
