The potential for CSP in Chile
There has been a lot of discussion about the potential
for concentrated solar power in Chile. The motiving
factor being that Chile is a country with high energy
costs and a rapidly growing demand for energy. To
continue Chile’s economic growth it has become
necessary to secure energy generation from more
sources and CSP is the perfect fit. The Great North
region in Chile possesses one of the highest solar
radiations of the world along with a strong mining
industry that requires substantial energy 24 hours a
day. In this guide, you will learn about the possibilities
of establishing a CSP industry in Chile, get analysis
on the current status of the industry as well as its
demand for energy, understand recent legislative
changes, and Chile’s interconnected systems..
Chile’s Energy Conundrum
“Our primary sources of energy are 44 % crude
oil, 10% natural gas, 17% carbon-based fuels, 8%
hydroelectricity, 20% wood biomass and an additional
1% of other combustibles like biogas and renewable
energy sources,” Sebastian Piñera, President of Chile.
During the Presidential election race in 2010 the
current President Sebastian Piñera knew that for Chile
to realize true prosperity, there was a serious energy
issue needed to be resolved. Currently the majority
of energy is imported, which means Chile has one of
the highest costs of electricity in the world.
In 1982 Chile privatized its energy markets and has a
growing demand for energy and a substantial copper
mining industry. Today more than 73% of Chile’s
energy comes from fossil fuels, 97% of which are
imported. Also due to a high percentage of imported
energy, Chile has become very vulnerable to changes
in its supply chain and fluctuating energy costs.

exceeding 3800 kWh/m2
in the region.
In addition to being a great resource of solar
energy, Northern Chile and the Atacama Desert have
several characteristics which are favourable towards
CSP technology, including:
„„ Large and extended desert lands which are
necessary for thermal solar plants, providing that
these lands are not being used for other purposes
such as real estate development or agriculture.
„„ The close proximity to energy consumption
centres.
„„ High demand for electricity and thermal energy,
which is currently being produced in carbon and
diesel plants.The development of CSP plants for
miningcompanieswouldhelpreducetheircarbon
footprint and improve the competitiveness of
Chilean mines in the international market.
„„ The demand for a stable and constant energy
supply. Especially in the Great North where the
consumption curve for big mines is steady 24/7,
making CSP’s ability to store and dispatch power
an ideal match for energy demands in the region.
Nevertheless, there are difficulties in developing
CSP plants:
„„ Despite having great stretches of land which are
appropriate for CSP plants, the heat generating
projects for mining processes need to be located
in close proximity to the mines. However this same
land is being exploited for mining opportunities.This
poses a difficult question as to where CSP plants can
be located and requires extensive analysis on the
cost-benefit ratio.
„„ Interconnection with the grid (CDIC-SING which
controls the northern region) cannot be reserved in
advance and it is granted on a first come, first served
basis. CSP plants generally require a longer project
development process compared to that of wind and
PV plants, which makes current interconnection
conditions unfavourable for CSP.
„„ There are limited water resources therefore dry
cooling is essential for CSP plants in this area,
increasing the price of electricity generated by CSP.
„„ As mines consume the majority of energy, CSP must
present energy costs comparable to what mining
companies are paying for their current energy to
make a CSP project financially feasible.
CSP Plants in Chile
„„ The ElTesoro Plant: This is a heat-producing plant
that Abengoa built and started operating at the
end of 2012. It uses parabolic trough technology
which has a potential of 14MWt and produces
heat for the mining industry.
„„ The Pedro de Valdivia Plant: This plant being
developedbyIbereólicaGrouphasatotalcapacity
of 360 megawatts (MW). It has four power stages
each with 90MW of parabolic trough technology
and several hours of molten salt storage.
„„ The María Elena plant: This ambitious mega
project lead by Ibereólica Group, has a total
capacity of 400MW consisting of 4 towers of
concentrated overheated steam of 100 MW with
13.5 hours of storage.
„„ The Mejillones Plant: Little is known about this
plant since its launch by energy giant GDF Suez
in partnership with the Solar Power Group. It
contains a solar power field alongside a coal
plant which was already owned by the developer
of Mejillones. We are waiting for developments
on the status of the project.

1. In terms of energy, what are the major obstacles
for a mining company?
The main challenge for mining companies is assuring
clean, safe and reasonably-priced energy over the
decades. The traditional sources of generation used
in Northern Chile, has been based on coal, diesel
and gas. These sources are now being strongly
questioned, given that they are fossil fuels, and the
gases produced is part of the Greenhouse problem
and increasing global warming.
In the present environment, the use of the latest
technology related to coal or to the development
of non-conventional renewable energy (ERNC)
is being considered as an important solution to
environmental problems.
2. It is said that the mines are resistant to change,
because of the problems they’ve had in the past
with new energies.Why is the mining industry
resistant to change and how can CSP adapt itself to
the needs of the mines?
When the mines experienced the gas cut years ago,
imposed by Argentina, they came face-to-face with
their extreme dependence on energy, which forced
them to use electricity more intensively.They turned
conservative because they didn’t want to have to
submit to rationing and to have continuing problems
with supply.
In this respect, mature technologies in developed
countries such as thermal solar energy become a
viable alternative because this energy can be stored
during periods when there is no solar radiation.
In addition, the heat that remains in a thermal solar
plant could be utilized in mining processes which
requires a high demand for heat (currently being
generated by diesel and gas) similar to the process
of Electrowinning, Heating and Sanitary Hot Water
(also known as Domestic Hot Water) on large mining
camps (which could reach 10,000 people).
3. What are the mining companies looking for
with renewable energy projects and, particularly,
with CSP?
Mining companies are looking to see the advantages
of the non-conventional renewable energies (ERNC)
that conventional energies don’t have. This will be
mainly in the low production of greenhouse gases
and a more favourable acceptance of using the
alternative energy with the authorities and local
communities.
Given this, CSP has advantages from the point of
view of its capacity to store and generate heat for use
in industrial processes.This makes it very attractive
and can turn into an excellent energy alternative in
Diego Lizana Rojas, Head of the Energy Efficiency and Renewable
Energy Unit, Compañía Minera Doña Inés de Collahuasi
Diego Lizana is a Forestry Engineer, graduated at the University of
Chile and studied a Masters of Renewable Energies at the Research
Center for Resources and Energy Consumption at the University of
Zaragoza in Spain.
Diego started working at the Mine of Doña Inés de Collahuasi as
a Specialist in Energy- Efficient Management, ERNC and Climate
Change. In this role he monitored and visited important CSP plants
such as Andasol 1 in Granada, Spain, PS 10 in Seville, Spain,
Nevada Solar One in Nevada, USA, and research centers such
as the Solar Platform in Almeria, Spain, and ENED in Freiburg,
Germany. Diego also acted as Vice-President of the Energy Efficient
Mesa Mining Company.
Diego’s personally believes CSP is an important alternative within
the range of non-conventional renewable energies capable of stabilizing the electrical
system of the Great North, particularly with storage of solar energy.
“CSP has advantages from the point
of view of its capacity to store and
generate heat for use in industrial
processes.This makes it very attractive
and can turn into an excellent energy
alternative in comparison with
conventional energies.”
