New Hampshire, USA --
Wind power growth is surging in Latin America and is expected to
lead the region's renewables race with some 10,000 MW of capacity slated
to come online in eight years, according to industry experts.
“Wind is growing exponentially as many plants begin
operating or are scheduled for construction,” says Nestor Lunas, a
research director at Latin American Energy Organization Olade, based in
Quito, Ecuador.
He adds there are ambitious wind development projets,
mainly in Brazil and Mexico, but also in Costa Rica, Argentina, Uruguay,
Venezuela, Colombia, Chile, Peru and Dominican Republic.
He says current capacity stands at 3,500 MW-4,000 MW and could easily reach 10,000 MW by 2020.
Regional governments are raising project incentives for
developers while the technology and infrastructure to build wind parks
and connect them to national grids has significantly improved and is
much more reliable than in the past, Lunas says.
The story for other renewables is not as promising,
however. Last year, Olade’s director of studies and projects Eduardo
Noboa predicted bioenergy production could soar 14 times by 2020, driven
by a plethora of planned ethanol and biodiesel projects. However, Lunas
says those targets now look overhyped as many projects have been
scrapped, due to a dearth of funding, technological problems and a
raging food-versus-fuel debate, accentuated by food crop crisis’in some
countries.
“The industry has not taken off like many expected,” Lunas
conceded. Apart from the problems listed above, he says environmental
agencies in different Latin American countries have also exerted huge
pressure to ensure projects become more environmentally sustainable,
raising their cost structure.
Lunas says a slower-than-expected arrival of
second-generation biofuel technologies to Latin America has also stalled
the industry.
Prospects for solar power south of the border are also
unexciting, Lunas adds. He says there is roughly 20 MW of installed
capacity in the region, mainly coming from Brazil, Mexico and Argentina
but that talk abou large projects elsewher has faded.
“Photovoltaic technology is still too expensive and
doesn’t guarantee enough radiation to feed the power grid on a constant
matter,” Lunas explains. “Unless project costs drop by half in five
years, I don’t see capacity rising very much.”
In a ray of hope for some solar firms, Mario Facio
Salazar, a renewable energy expert at Baker & McEnzie in Mexico
City, says Mexico and other regional governments are allowing home
owners to use solar panels and deduct their energy savings from their
power bills – a move that could boosting the industry’s development,
though not on a mass-scale.
Salazar agreed bioenergy’s growth will trail behind wind.
He adds that in Mexico, biofuels production has halted due to oil giant
Pemex’s failure to purchase the fuel at competitive prices. This decline
in expected production has offset bigger gains in ethanol-crazed
Brazil. Scarce food crops are also making it more expensive for
producers to obtain feedstocks south of the border, Facio adds,
complicating the growth picture for biofuel producers.
Shale Gas Coud Dent Hydro
Wind apart, hydropower (which status as a renewable energy
continues to generate big debates) is expected to grow much stronger
than wind. Noboa last year predicted capacity would rise five-fold from
147,879 MW by 2020. However, Lunas says that projection now looks overly
ambitious because of the rising popularity of shale gas in Latin
America.
Currently, roughly 57% of Latin America and the
Caribbean’s electricity generation stems from hydropower while another
40% comes from thermoelectric power plants using fossil fuels and
natural gas. The rest comes mainly from wind, biomass and solar,
according to Lunas.
Recent shale-gas field discoveries in Mexico and
Argentina, combined with regional governments’ efforts (notably Chile
and Peru) to assess its production potential, could dent hydro’s growth
curve, however.
Last month, Mexican state-owned oil giant Pemex announced
it will drill 20-25 oil fields in the Tampico-Misantla area near the
Gulf of Mexico to extract shale gas and shale oil. Last year, Pemex was
able to extract the fuel from six fields.
According to Pemex, Mexico has 60bn barrels of equivalent
crude oil in shale gas reserves of which 31.9bn are shale oil. In
Argentina, too, plans are afoot to develop the cleaner fuel, which
advocates boast emits 50% less CO2 than coal– albeit at much higher
extraction costs.
According to Argentine oil firm Tecpetrol’s energy
resources director Mauro Soares, Argentina has the potential to churn
out 774tn cubic feet of shale gas, mainly from the Vaca Muerta, Cuenca
Chaco-Paranaense and Gulf of San Jorge regions. In gas-dependent Chile,
the government has also identified“significant” yet undisclosed shale
gas reserves in the Magallanes area.
Shale gas remains very costly and difficult to extract,
however. Pemex esimates each well will cost $12-$15 milion to drill.
However, it expects those costs to fall to $5-8 million as the
technology develops.
Beatriz Olivera, energy and climate change campaign
director for Greenpeace Mexico, says shale gas could develop strongly in
Latin America if advocates show it can be produced at a lower cost than
other non-convential fuel alternatives.
If it can be made more economically feasible, Olivera says
shale gas is likely to begin replacing natural gas as the main fuel to
feed Latin America’s large network of thermic power stations, raising
its contribution beyond the current 40%.
“What this means is that instead of 57% of electricity
coming from hydro, we could have 45% from hydro and 52% from thermic
plants in 2020,” Olivera muses.
She adds: After big [production] discoveries in Mexico and Argentina, there is a lot of talk about shale gas.”
“It’s the fashionable transition fuel right now and governments are starting to look at its development potential.”
