One of the most cost-effective sources of electricity available
in Mexico
CASE STUDY: GEOTHERMAL POWER
Los Humeros II, Units 9 & 10Mexico
Comision Federal de Electricidad (CFE) granted Alstom a contract
for the supply of 2 x 25 MW geothermal power plant. Both turnkey
plants included the installation of a geothermal steam turbine and
all associated equipment including the engine house, substation,
cooling system and generator. Production on the plant comprised a
control room to monitor and control the operation of both units as
well as the enlargement of the existing eight back pressure units
in the field.
Located in the Mexican State of Puebla, a wooded mountainous
area 200 km eastof Mexico City, Los Humeros II geothermal power
plant used drilled wells to extract steam from a depth of up to
3,500 meters where the geothermal reservoiris located.
Production took place at the Alstoms Morelia factory a
specialised centerin the manufacturing and assembly of turbines,
generators, large-sized-diaphragmand blade fabrication.
Units 9 and 10 operate as base-load power, feeding the nations
electricaldistribution grid, being capable of producing more than
400 GWh of cleanelectricity per year respectively, thus allowing a
regional and international industrialscheme with supplies from
Mexico, USA, Europe and more.

SCOPE OF THE ORDER
Alstom is a global leader in steam turbine technology with more
than 100 years of experience in manufacturing, delivering,
installing and servicing steam turbine generator sets from 5 MW to
1,800 MW for a wide range of applications, including geothermal.
Geothermal is one of the most reliable sources of renewable
power.
CFE launched an international bid with technical specifications
to build a turnkey geothermal generation unit, including equipment
to regulate and enhance geothermal steam, a geothermal steam
turbine, generator, direct contact condenser, hotwell pumps,
cooling tower, distributed control center, turbine control, motor
control and electrical equipment rooms, substation, engine room,
travelling derrick, firefighting system and Heating Ventilation and
Air Conditioner (HVAC), as well as civil works, project management
and commissioning. Alstoms tender provided an integrated solution
that fulfilled CFEs needs, including a control room which will
enable the remote controlling and monitoring of the geothermal
plant, for autonomous operation.
REDUCINGCOST OF ELECTRICITY
Alstom pioneered the commercial exploitation of geothermal power
in New Zealand in the 1950s. Today, we offer an extensive portfolio
of cutting-edge solutions for geothermal applications that are
grounded in technologies that have been proven in geothermal
applications worldwide. For the most challenging geothermal
applications, we are able to tailor our solutions to take account
