Solar Bolivia

Bolivia has a high energy potential, both for traditional and alternative energy.

Given its geological nature, the country produces more natural gas than oil (62% of total liquids produced from condensed).

Its natural gas reserves are the second largest in South America (after Venezuela), but considering those that are liquids free, they are the first. Besides, it is expected that they will increase by 200 to 300 trillion cubic feet.

This is the basis for the Bolivian economy. The country has export contracts with the countries that surround it. For example, Brazil has a contract for 30 million cubic feet per day for 20 years.

The power sector accounts for 63% of natural gas sales.

The electricity generated in Bolivia comes from hydroelectric plants (35%) and thermal power stations (65%).

The National Interconnected System (SIN) is 90% composed by the main centers of production and consumption (La Paz, Cochabamba, Oruro, Potosi, Chuquisaca, Beni and Santa Cruz) and by isolated systems in smaller cities and towns that complete the remaining 10% of the national electricity market (Department of Pando).

Bolivia is determined to change its energy matrix, which currently is based on thermal generation.

Authorities have repeatedly pointed that their goal is to achieve a mix of 70% of power generation by hydroelectric or from alternative sources such as wind and solar, and limit thermal to the remaining 30%.

Therefore it targets to incorporate around 183 MW of renewable energy by 2025.

Two thirds of Bolivia, whose latitudinal position is between the parallels 9º 40′ S and 22º 53′ W, are situated within the range of greater solar radiation.

Thanks to this situation, the country has one of the highest levels of solar intensity in the region.

Solar incidence in the country reaches an annual average of 5,4 kWh / m² per day of intensity and 7 h/day of effective insolation.

However, perhaps because of the high availability of natural gas, Bolivia currently has no regulations and legislation that fosters sustainable development for solar installations.

Solar Photovoltaic Argentina

The Argentine photovoltaic market is segmented into 3 types of applications:

1- Rural uses.

The demanded equipment are for electrification of rural housing posts (50W-80W); lighting systems (30W-100W); to feed water pumps that replace the traditional multi-blade mills (50W-400W).

2- Professional or business purposes.

Providing energy to telecommunications systems (100W – 400W), telemetry, markings, signage, highway emergency systems (20W – 50W), cathode protection and pipeline shutoff valves (over 20kW).

3- Institutional demand.

Includes social assistance programs, power regulating entities, organizations and state (provincial) energy companies. Equipment requests for lighting and electrification of schools, medical centers, police stations and residential users. Powers between 50W and 400W.

Until the year 1999 the demand for PV modules remained steady between 20% and 50% annual growth. From that year on, and especially after the devaluation in 2001, demand for these modules has suffered a sharp decline that has begun to reverse since 2004.

There is no domestic solar modules manufacture.

With approximately 1 to 2 MW of installed power per year, mainly in isolated applications, it seems that the only way for this market to grow is through the development of large-scale projects.

In conclusion: government authorities have not learned the lesson taught elsewhere.

Efforts should be focused on distributed systems’ installation and integration of PV in urban environments, developing residential, secondary and tertiary sectors.

The future of a solid and consistent solar PV sector clearly requires the development of:

1) A limited number of grid connected big projects.

2) Encouraging installations on residential and businesses roofs on the basis of a net metering or feed-in payment.

Currently there is no feed-in payment for solar residential electricity.

There are purchasing agreements granted in the solar electricity program GENREN of US$ 572 / MWh (Three times the average of the PPA agreements awarded in the rest of Latin America).

In the city of San Juan, a facility that used a combination of fixed and followers, polycrystalline, mono-crystalline and amorphous silicon cells structures was inaugurated in 2012.

It has 1.2 MW and has become the first solar photovoltaic plant connected to the national network of integrated power system in South America.

At domestic levels, investment in a solar PV system is recovered in about 5 years compared to a fuel generator.

Compared to the electricity network, the figures are radically different.

The electricity network has an approximate price of US$ 47 per MWh against US$ 142 solar MWh.

In other words, solar electricity costs triple the network. In this scenario, the solar investment would be recovered in 98 years (more than 3 times the equipment’s life).

The paradox is that according to an analysis by the Environmental Protection Agency of the City of Buenos Aires (APRA) each MWh that adds to the country, provided by thermal power plants, costs US$ 344.

Therefore, thermal power plants (the majority in country’s energy matrix) are selling to end users 7 times cheaper than the actual cost of producing and transporting electricity.

In addition to this, about US $ 15,000 million annually are used to import fuels.

In short, lack of common sense and any planing.

If the electricity price of other cities within the region (Santiago, Montevideo and San Pablo) was paid in Buenos Aires, the solar system investment would be recovered in 12 years.

From 2016, we will see if political change in the country will lead to the end of energy crisis and sustainable development of solar photovoltaic energy.

Solar Thermal Argentina

In terms of solar thermal energy, Argentina has entered a process of incorporating this technology taking the construction sector as an engine for market development, in absence of laws and regulations to boost it.

There are isolated initiatives. In fact, there are municipalities with Bills or solar ordinances, such as the city of Rosario.

But we could say that the field of solar thermal energy in Argentina is still in diapers.

Up to today, year 2015, there are no comprehensive measures of solar resources available, equipment have not been subjected to testing or certification and have no market sector statistical information.

Generally thermo-siphon systems are installed for DHW heating in houses and townhouses where there is no access to the gas network. Equipment for pool heating are also installed.

A 2009 estimate indicates that around 2,000 m² (about 22,000 ft²) of collectors were installed that year and were about doubled in 2010, reaching 4,000 m2 (about 43,000 ft²).

Flat collectors then constituted 2/3 of the market with a large proportion of domestic products, being vacuum tubes the most imported collectors.

In 2015, it is calculated that above 30,000 m² (around 323,000 ft²) collector capacity was installed; half of them for heating outdoor pools.

Most companies in the sector are located in the Central Region (mainly in Buenos Aires) and the Northwest Region is the one with the largest area of collectors installed, followed by the Northeast.

How could this technology’s sustained development be boosted ?

As far as the public sector is concerned, it would require:

– Elimination of the competitive disadvantage caused by high subsidies for electricity and gas network.

– Standards sanctioning and incentives creation.

– Set an example by incorporating solar systems in its infrastructure facilities.

As for the private sector, it would require:

– Introducing improvements in product quality.

– Training skilled labor on sizing and system design, installation and maintenance.

– Facing the additional challenge of foreign competition, in some cases, with equipment at a lower cost and better performance than those of domestic manufacturing.

Only in the residential sector, there is an estimated potential of 6 million m2 (about 65 mill ft²) for the production of DHW; 2.2 million m2 (around 24 mill ft²) in the public, commercial and services sectors, plus a significant potential in the industrial sector.

Considering 20 years of useful life for a thermal solar system, full investment could be recovered in about 15 years in Buenos Aires province, for instance, when compared with actual price of gas network and considering its level of insolation.

However, in cases of bottled gas and electricity, solar thermal power technology is already profitable in many parts of the central and north regions of the country.

Compared with bottled gas, investment in solar thermal systems could be recovered in 2 years.

Compared with the use of an electric water heater, investment in solar thermal systems could be recovered in about 5 years.

A consistent solar thermal market would provide several benefits to the country:

– Reduction in conventional energy demand.

– Reduction in energy imports

– Reduction of greenhouse gases’ emissions.

– Creation of a new industry sector and new jobs.

– Creation of a national industry sector with high added value.

Solar Argentina

In 1992, Argentina divided the public electricity sector in generation, distribution and transmission, and sold it to private investors.

When the 2001-2002 economic crisis shook the country and its currency was devalued, the government, fearing the political cost an electricity price increase would cause, froze natural gas prices and end users tariffs in 2002.

The solution worked in the short-term, but stopped the exploration of new energy sources and investment in infrastructure improvements by foreign investors.

The national natural gas extraction declined, leaving power generation facilities unused and increasing energy imports.

With the economic recovery, demand for energy soared by an average of 5% a year since 2003.

Enarsa was created in 2004 with the primary mission of exploring and extracting hydrocarbons, oil and natural gas; plus transportation and distribution of these resources. However, power failures remain a problem.

Argentina has invested heavily in a renewable resource: water. This resource accounts for about 35% of electricity, so a greater diversification is necessary to avoid the problems a severe drought would cause.

Oddly enough, judging by the development it has taken so far, Argentina is one of the countries with the highest potential for renewable energies.

Argentina could supply all of its electricity consumption with renewable energy, and could even become a net exporter.

In 2006 the regulatory framework was established with the enactment of Law 26.190/06, giving renewables a national interest. It was set as a target for 2016, that Argentina should reach 8% of electricity generation from renewable sources.

Current figures indicate that in 2016 it will barely exceed 2%, achieving, therefore, only a little more tan 25% of the objective.

In 2009, the national government launched with Enarsa (the public energy company) the GENREN program, which offered to buy 1.000 MW of renewable energy by 15-year fixed contracts.

In June 2010, after an exhaustive analysis, the winners were announced and a total of 895 MW were approved.

Most of the bids were for wind energy.

Even though the central and northern parts of the country enjoy many sunshine days throughout the year that would allow many applications to take advantage of solar energy, only 20 MW photovoltaic solar energy projects were granted in the province of San Juan.

Economic instability in recent decades contrasts with the expected energy crisis in which Argentina is sinking ever more rapidly.

With rates that do not reflect the true cost of resources nor the need for investment and a subsidies policy that will soon come to an inevitable end, renewable energies gain a value that they never had before.

Uncertainty about the availability and value of energy in the future is a question that only the state can solve with energy planning and implementing public policies, promoting energy efficiency and clean energy.
