Geothermal in Pre-Columbian Epoch
In Mesoamerica, and especially in
Mexico, settlements were related to
volcanoes and geothermal
manifestations.
Xiuhtecutli, Aztec goddess of fire, was
considered the link between the heat of
Earth and heaven.
The Aztec’s five suns or epochs:
o The third sun, named Quiahuitl
Tonatiuh (solar fire rain), was
destroyed by volcanic eruptions.
Other Aztec gods related
Huehuetéotl,
ancient god of
fire and father
of gods.
Tláloc, god of rain and fire.
Geothermal in the Colonial period
In 1540, the Spanish chronicler Pedro
Castañeda described the arrival of the
expedition to the thermal manifestations
of Laguna Volcano in Cerro Prieto:
“...Dieron con unos médanos de ceniza
ferviente, que no podía entrar nadie en
ellos... La tierra que hallaban temblaba
como témpano y parecía que estaban
debajo algunos lagos. Era cosa admirable
que así hervía la ceniza en algunas
partes, que parecía cosa infernal...”
Geothermal in the Colonial period
In 1540, the Spanish chronicler Pedro
Castañeda described the arrival of the
expedition to the thermal manifestations
of Laguna Volcano in Cerro Prieto:
“... They went at some boiling ash dunes,
and nobody could get into them... Ground
was shaking like iceberg and looked like
they were some lakes under it. It was an
admirable thing that ashes were boiling in
parts, which seemed an infernal thing...”
Known hot springs in Mexico
Hot water:
o Atotonilco,
term coming
from náhuatl
o Puruándiro,
term coming
from
purépecha
o Pathé, term
coming from
otomí.

Geothermal expertise and economic solvency
Possibilities (and obligation if necessary) to jointly exploit the same reservoir with two or
more different concessions
o All brine must be inject into the reservoir
o ‘Round 0’ for CFE and ‘Round 0.5’ for private developers
Present status
As result of ‘Round 0’ SENER
awarded to CFE:
o 5 Exploitation concessions
for its four fields, plus the
Cerritos Colorados, Jal.,

Present status
As result of ‘Round 0’ SENER
awarded to CFE:
o 5 Exploitation concessions
for its four fields, plus the
Cerritos Colorados, Jal.,
and
o 13 Exploration permits in the
areas of Cerritos & Calderón
Cucapah in the state of Baja
California, Volcán Chichonal in
Chiapas, San Bartolomé de
los Baños in Guanajuato, La
Soledad, Las Planillas & San
Marcos in Jalisco, Lago de
Cuitzeo, Araró. Ixtlán de los
Hervores & Los Negritos in
Michoacán, Los Hervores in
Nayarit, and Acoculco in the
state of Puebla.
As result of ‘Round 0.5’ SENER awarded:
o 1 Exploitation concession to Grupo Dragón for the Domo San Pedro, Nay., area.
o 1 Exploration permit to Mexxus-RG for the Volcán Ceboruco, Nay., area.
Future geothermal development
o Up to now, SENER has received several applications for exploration permits for other
geothermal areas, yet it has not awarded none.
o The Regulatory Energy Commission (CRE) will accept offers for
Clean Energy Certificates (CELs) in next March.
o Hydrothermal proven reserves are currently estimated at
112 MW and probable ones at 230 MW (only in the six
fields already awarded to CFE & Grupo Dragón).
o Hydrothermal measured resources are estimated at
195 MW, indicate resources at 830 MW & inferred
resources at 1210 MW.
o Geothermal potential for hot dry rocks, developable with
EGS technologies, is still under assessment by the CeMIEGeo, yet it is estimated a minimum of >5000 MW.
o The SENER’s Inventario Nacional de Recursos Renovables estimates the national technical
potential at 13,400 MW.
