Supporting your maintenance strategy

Alstom's expertise: The first Alstom electrical machines were manufactured in

1887. Since then, Alstom has designed, manufactured and serviced more than

4000 generators worldwide. This experience allows Alstom to propose reliable,

adaptable, cost effective and simple site implementation retrofit and repair

solutions on numerous technologies.

Overtime, Alstom has gained in-house expertise on other OEM (original equipment

manufacturer) technologies through repairs and retrofit up to 1200 MVA.

Changing markets: Deregulation and introduction of more stringent environmental

laws have created new challenges for power plant operators and have resulted in

competitive markets for electricity and a strong drive to reduce generating cost and

fuel emissions. Alstom offers reliable solutions allowing you to stay competitive.

Reliable solutions

ENHANCED EFFICIENCY

Retrofitting of ageing existing generators with modern Alstom technology

offers an attractive return on investment with a reduction in fuel cost and plant

emissions.

CAPACITY INCREASE

ncreased demand for power and the high market price during peak periods

are powerful drivers for increasing the MW capacity and reliability of existing

generating plants.

A generator retrofit offers the most cost effective means of increasing capacity in

most cases (typically 10% and sometimes up to 15%) and, therefore, increasing

revenues when combined with a boiler or steam turbine retrofit.

FLEXIBILITY

Flexible operation modes may cause drastic load variations for the generators,

which affects their winding temperature and relative thermal expansion.

Retrofitting with state of the art technology offers a more homogeneous

temperature distribution for operation without damaging the general conditions

of the winding and its supports.

IMPROVED RELIABILITY

Retrofit increases the time interval between outages and reduces both the outage

duration and maintenance cost.
