Latin America’s largest solar power plant is now supplying power to the city of La Paz in Baja California Sur. The Aura Solar I photovoltaic power plant has an installed capacity of 30 MW. The plant was officially inaugurated on 19 March 2014, and will supply about 82 GWh/year of electricity to around 164,000 residents of La Paz, more than two-thirds the city’s total population of 220,000. It is located a short distance east of the city, and replaces an old, air-polluting thermoelectric plant.

Auro Solar 1 project, La PazThe new power plant, owned by Corporación Aura Solar, is the largest photovoltaic power plant in Latin America, according to company chairman Daniel Servitje Montull. The 100-million-dollar plant occupies 100 hectares (250 acres) and was constructed by engineering firms Gauss Energía and Martifer Solar. The project relies on about 131,800 solar panels and has an estimated operational life of 30 years. About 25% of Mexico’s electricity is currently generated using clean energy sources. Mexico has set a national target of 35% clean energy by 2024, in order to minimize Mexico’s contribution to global climate change.

Have big cities in Mexico succeeded in meeting people’s needs?

In 2012, the Mexican Institute for Competitiveness (Instituto Mexicano para la Competitividad AC, IMCO) published an analysis of the competitiveness of 77 of the largest cities in Mexico, looking to see which of them offered balanced growth alongside a good quality of life for their inhabitants.

portada_indiceThe elements of competitiveness considered included the degree of compactness (more compact cities are more efficient and sustainable), public finances, transport, security, water management and waste management. The IMCO methodology is explained in detail in the report Índice de Competitividad Urbana 2012. In short, IMCO evaluated each of the 364 municipalities involved in the 77 cities, using 60 indicators grouped into 10 mutually-exclusive sub-indexes.

Between them, these 77 cities house 63% of Mexico’s total population and account for 80% of Mexico’s GDP. 55% of Mexico’s population live in cities managed by two or more municipalities. IMCO found that public transport was adequately coordinated in only 13% of cities with two or more municipalities, while urban planning was coordinated in 35% of the multi-municipality cities.

The IMCO report concludes than most Mexican cities do NOT offer balanced growth and a decent quality of life for residents. Individual cities can be compared using this IMCO site.

The only city offering a “High” level of competitiveness was Monterrey.

Several cities offered an “Adequate” level: Mexico City, San Luis Potosí, Querétaro, Ciudad del Carmen, Saltillo, Tampico, Colima, Guadalajara, Mexicali, Monclova and Campeche.

At the other end of the spectrum, the competitiveness of several cities in Mexico was categorized as “Low”: La Piedad, Cd. Cárdenas, Rioverde, Matamoros, Tehuantepec, Tijuana, San Francisco del Rincón, Cd. Juárez, Ensenada and Poza Rica.

The lowest levels of competitiveness (“Very Low”) among the 77 cities studied were found in two cities in the state of Guerrero: Chilpancingo and Acapulco.

The report used data from 2010, so some aspects of these cities will have changed since that date. For example, the sharply increased murder rate in Monterrey since 2010 will have reduced its lead over other cities.

Certain cities have faced severe challenges of rapid growth. In recent decades, the cities that have grown most rapidly have not been the very large cities like Monterrey, but mid-sized cities. One example of a mid-sized city that has grown rapidly is Ciudad Juárez, whose area grew 497% from 1980 to 2009, while its population rose 70%. This rapid growth may have contributed to the high levels of crime experienced in the city.

IMCO concludes that Mexican cities are showing clear signs of not functioning well: chaotic expansion, heavey traffic, high levels of air pollution, poor supply and/or quality of potable water, high crime levels. These have caused cities to lose competitiveness and the capacity to attract human talent from outside, whether for business, sports or research.

The single obstacles to increased competitiveness are the lack of professional urban management, and the fact that many cities involve two or more municipalities. The laws governing municipal elections inevitably mean that administrations are short-term, with a high level of staff turnover. The impossibility of re-election means that many urban projects are overly superficial and they lack continuity from one administration to the next.

IMCO suggests that a new administrative position be created: the city manager (administrador urbano). The city manager would be a professional manager, and would ensure that the city has adequate coordination for all urban public services, even where more than one municipality is involved. This would free the municipal politicians from having to tackle the day-to-day management issues of the city and allow them more time to engage productively with the citizenry. However, for this to happen, a major institutional innovation is required.
