Switching on Remote Communities through Electricity Access in Mexico

Centralized solar farms were installed in 40 locations distributed among 8 Mexican states—Baja California Sur, Chihuahua, Coahuila, Durango, Guerrero, Nayarit, San Luis Potosí, and Sonora—to provide electricity to extremely remote, primarily indigenous communities previously lacking energy access due to difficult installation and servicing conditions. The project reached indigenous peoples in 18 of the 40 benefited communities. By the project’s closing, a total of 2,235 households had electricity access through the installation of 2,357 kW of new renewable capacity.


In the first decade of the twenty-first century, electrification in Mexico had reached 96.6 percent coverage. Providing electricity to the estimated 3.5 million people remaining without access, approximately 60 percent of whom are indigenous, proved particularly challenging, however. This was in large part because most of these individuals lived in small communities in remote, isolated locations. Compounding challenges, including lack of other basic services and infrastructure such as roads, water access, telecommunications, schools, and health services, were also prevalent in these communities. The government recognized that, due to population growth, the number of people without electricity would increase by 20 percent over the following decade, making access to electricity an even more pressing issue.


Rural infrastructure development and poverty reduction projects require strong capacity building, and building institutional capacity and enhancing coordination can be a slow process, especially when, as in Mexico, many government agencies and stakeholders have legal mandates to participate in planning, decision making, financing, and executing rural development projects. In this context, the Mexico Integrated Energy Services Project (PSIE, Proyecto Servicios Integrales de Energía) provided a much-needed boost for the federal government’s rural electrification efforts, in terms of both infrastructure financing and technical assistance support.

PSIE was designed to support the rural electrification strategies and actions established by the Secretariat of Energy (SENER) and prioritized by the federal administration. In supporting this initiative, the World Bank leveraged its extensive experience in rural electrification and renewable energy to promote relevant international best practices, thereby further supporting poverty reduction efforts in Mexico.

A subsequent restructuring of the project to address initial delays in implementation revised the project scope to focus on one photovoltaic technology: mini-grids based on centralized solar farms (CSFs). CSFs provide a sound, reliable, utility-like electricity supply with much larger capacity per connection than home-system solar units; this ability to deliver greater electricity benefits per household renders CSFs particularly suited to supplying power to small, isolated communities. Because CSFs are considered a renewable energy source, any negative impact and CO2 emissions from the installation are projected to be lower than would result from traditional energy sources.


The Mexico Integrated Energy Services Project supported the government’s long-standing goals to extend electricity to all parts of the country. Through the strategies and actions initiated and supervised by SENER, and with Bank support, rural electrification and renewable energy were widely extended using international best practices and environmental sensitivity, thereby further reducing poverty and extending opportunity in previously struggling communities.

PSIE successfully installed CSFs and related infrastructure to supply electricity to the targeted remote communities, including these specific results: 

  • A total of 2,235 households in 40 remote rural communities have been electrified through the installation of 2,357 kW of new renewable capacity.
  • The renewable installed capacity has potential to avoid 139 thousand tons of CO2e per year through the displacement of more carbon intensive sources of energy.

In addition, access to efficient and sustainable energy services is expected to lead to a better quality of life for the benefited residents. Thus far, important social and economic benefits achieved have included:

  • Enhanced public services, such as remote access to educational resources and health infrastructure.
  • Better and cheaper access to communications and water pumping.
  • Increased productivity and greater security from public lighting during night hours.  

Internet access is expected to provide the greatest impact, however, with major benefits including:   

  • An exponential effect on communication and education. 
  • Development of productive uses, with beneficiaries gaining full access to all federal and local entrepreneurship programs.

By the project’s closing, one beneficiary community, Potrero de la Palmita, Nayarit, had presented a plan to install a water treatment facility. This installation is expected both to foster sustainable use of resources and to create employment opportunities.  

Bank Group Contribution

The World Bank, through the International Bank for Reconstruction and Development, provided a loan in the amount of US$ 15 million and a Global Environment Facility grant in the amount of US$ 15 million, for a total of US$ 30 million, to support the Mexico Integrated Energy Services Project.


The institutional framework for implementing the Mexico Integrated Energy Services Project was led by SENER, with direct responsibility for project oversight, and Comisión Federal de Electricidad (CFE), as the government agency responsible for procuring the 40 CSFs and complying with social and environmental safeguards. A dedicated Project Implementing Unit within a key SENER directorate provided monitoring, financial management, and reporting for the project.

The project’s focus on off-grid solutions complemented both the rural electrification strategy of the Basic Infrastructure Program for Indigenous People Development[SB1]  led by Mexico’s Indigenous People Development Commission, as well as the objectives and scope of the Micro Regions Program, implemented by the Secretariat of Social Development with the goal of improving social and economic development in the municipalities with the highest degree of poverty.  


The project was designed to provide electricity to households, businesses, and public facilities in rural areas with predominantly indigenous populations. By project closing, 2,235 households in eight Mexican states had benefited from this operation. Individuals affected by the project were very appreciative. A resident of Nuevo San Diego de Tezains Ejido offered the following comments:

“What has been the most important change? The refrigerator because before, the food spoiled. Imagine that they had to make food just for the day, and the times that there were leftovers, they spoiled.”

“I am impressed with this work. All the people are very happy. Imagine that [we can use] washing machines, irons, well everything that is essential. We are very happy.”

Moving Forward

The Mexican government has expressed an interest in pursuing a second operation that would build on lessons learned and take advantage of the strengthened institutional capacity created under this project. In many ways, the project represented a pilot exercise for both the government and CFE in their attempts to achieve 100 percent electrification across the country, and it made evident the significant challenges in reaching the last approximately 2 percent of the population still without electricity access. The proposed subsequent intervention could serve as a piloting exercise for the Fondo de Servicio Universal Eléctrico, a fund established by SENER in late 2016 and dedicated specifically to reaching 100 percent electrification coverage in the next five years through energy reforms.

Learning from the implementation of this project could have enormous replicability effects in other Latin American countries, many of which face similar challenges in reaching their last-mile communities and achieving 100 percent energy access.
