Mexico to increase geothermal energy generation with IDB support

US$108.6 million loan will help diversify the country’s energy matrix and reduce its dependence on fossil fuels

The Inter-American Development Bank (IDB) has approved a modification of a loan totaling US$108.6 million that aims to increase private investment in electricity generation projects from geothermal sources, putting at the developers’ disposal a number of financial mechanisms tailored to meet the specific needs of each project at every step of their development. This includes the following phases: exploration, drilling, field preparation, construction and operation of private geothermal projects, as well as reducing the value at risk for developers, which is the main barrier to investment. The program’s goal is to finance up to 300 MW of geothermal capacity over a 10-year period. It also hopes to leverage other public and private funds to contribute to Mexico’s geothermal sector with estimated investment levels to the tune of US$4.2 billion for proven geothermal reserves.

The Program for Financing and Risk Transfer for Geothermal Energy in Mexico, structured under the global loan modality, will consist of two main components: risk mitigation for geothermal projects and financing adapted to the different phases of project exploration and execution. In addition, it will have a third component of technical assistance to support execution and other implementation costs.

Mexico is the main emitter of greenhouse gases from fuel burning in Latin America and No. 12 in the world. Its ambitious goals include reducing these emissions by 25% by 2030, with the energy sector having the biggest reduction potential. Moreover, 80% of Mexico’s energy continues to be derived from fossil fuels, making it even more imperative to transform the country’s energy generation system to make it more sustainable and profitable.

“Geothermal power is baseload energy, with a capacity factor of 95%-plus, allowing to have electricity available 24-7 at a competitive price, much like natural gas. Like solar and wind energy, it is renewable, but without their characteristic intermittency. It is fully climate-change resilient and has an enormous energy density, which paves the way for getting large amounts of energy in a relatively small area,” says Christiaan Gischler, project leader and IDB’s geothermal theme team leader. Its direct use has high-impact applications and social advantages. “Low enthalpy (low temperature) applications are crucial for the fruit drying industry, and the use of steam is critical for small- and mid-sized enterprises,” he adds.

Geothermal energy helps create new jobs and take advantage of economies of scale, combining the knowledge of Mexico’s existent extractive industries to perform the perforation work needed during the exploration phase.

The program’s total amount is US$108.6 million: US$54.3 million financed with resources from the IDB’s Ordinary Capital, US$51.5 million from a contingent recovery grant financed with resources from the Clean Technology Fund (CTF); and US$2.8 million in technical cooperation.

There are currently two processes under way: first an International Public Tender to pick the companies that will be in charge of performing the drilling work during the exploration phase; and second, a Call for the  Selection of the Eligible Developers who will participate in this program.
