Four years ago Nexus Energía was a company that serviced less than 900 clients. Just one year later that
number had increased to more than 52,000! Increasing our client base by more than 51,000 in less than a
year from different business areas, each more complex and specialized, required a massive effort at all com-
pany levels. And even after that spectacular growth, we have continued to innovate, launching dozens of new
products and services, inaugurating the current headquarters, as well acquiring a company: our new German
division, which started a process of internationalization.
We felt it was convenient for Nexus Energía to stop and analyze the current situation
before going any further. And this is what we have done. We committed ourselves
to take a deep breath and consider that we are a Group that deals with almost 10,000 GWh per year with
about 60,000 clients, generating a consolidated turnover close to €900 million. During the last year we
have worked on the reorganization of different areas, from upper management to commercial strategy,
and our operational departments. It has undoubtedly been difficult to deal with those decisions, especially
those related to the resizing strategy that was put in place in order to face our business challenges in a
more efficient way. We shall not misjudge the economic current situation of the country, which has pus-
hed us to adapt our activity and adjust our business volume to a comfortable level, allowing more financial
independence which has moderated out previously record-level ratios.
Thanks to the work that has been done during 2012, we face 2013 with renewed energies, wishing
to continue improving and innovating, willing to surprise the market with new
services and products that shall soon be released! Follow us!

General Director

6. Annual Report 2012
Electricity Supply
Adapting to the current market situation in 2012 represented a huge challenge for Nexus Energía given the
extreme economic circumstances faced by Spain. However, the innovative spirit of the company has helped
to translate the growing unpaid bills issue into an opportunity by releasing a new product called “Prepay-
ment”, which gives consumers a better deal, eliminating both the financial cost and the risk as a marketer.
The company ended 2012 with more than 29.000 supply points and 2.168 GWh/year in electricity volume. In
Germany, the figures were 720GWh/year with 8.197 supply points.
The parent company´s portfolio, diversified by supplying public institutions, small and medium sized com-
panies, and domestic consumers, pursues a balance between fixed price contracts against spot (42% of the
total), gives stability to the Group.
Alongside this, Nexus Energía supplies energy to other companies through bila-
teral contracts, giving a volume of 618GWh/year.
In 2012 Nexus Energía reviewed the number of branches, looking at the
proximity of the company to clients and implementing a new organisa-
tion, as well as new procedures that give a more personalised service to
clients.
Grupo Nexus Energía closed the year 2012 with just over 37.000 supply points
and almost 3.000GWh/year power supplied between Spain and Germany.

Gas Supply
What do we do?
2012 saw an increase of 43% in the sales volume of Natural Gas compared to 2011, reaching
a total of 516,000MWh. 80% of this volume is distributed to end customers, with 20%
going to Distributors of Last Resort (CUR in Spanish), remaining a solid alternative to cu-
rrent operators. Two relevant facts are that Nexus Energía has a high contract renewal
rate in Spain, while in Germany almost 440,000 MWh has been supplied. The joint
supplies between the 2 countries exceeded 2,500 in 2012.
In 2012, Nexus Energía renewed the contract with ENAGÁS, increasing the
contracted capacity both in terms of Operational Storage Transport (AOC in
Spanish) and underground storage. Nexus Energía is managing the operation
of the contracted capacity on the LARRAU pipeline, connecting Spain to nor-
thern Europe, and with which Nexus Energía will provide gas to its customers
during 2013.
Nexus Energía took part in the various Gas auctions that took place in the Spa-
nish gas system, for both underground storage and TUR ( last resort tariff) in Spain
during 2012. The effort was focused on
diversifying its gas supplies with different
providers, closing contracts both at fixed
and spot price for liquefied and natural gas, in
order to secure an optimal purchasing gas mix.
The company’s goal for 2013 is to achieve new synergies with its German subsidiary,
Nexus Energie GmbH, in order to participate in the European gas markets and enable
the Group to optimize Nexus Energía’s joint procurement.

8. Annual Report 2012
Services to Energy Producers
38% market share, 97% contract renewal rate in Spain; the key to our success is the
large number of production plants with a diverse range of capacities and technologies,
which allows us to offer both competitive prices and a flexible service.
2012 was a very active year in the renewable energies sector with regards to the la-
test law RDL 1/2012, which affected existing rules and caused serious difficulties for
new plants under the Special Regime to enter the sector due to lack of a reliable,
long-term economic system. However, Nexus Energía has offered solutions to more
than 17,000 plants, managing almost 6,000GWh/year. As a result of our continuous
innovation, we currently have a contract renewal rate of 97%, with a high percentage
of satisfied clients, and our market share of more than 38% makes Nexus Energía the
market leader in the representation of photovoltaic producers.
Nexus Energie has followed the same path in Germany, initiating the representation of
producers and accounting for 60MW of installed power capacity and 131GWh, mainly
of biogas.
For the last 2 years Nexus Energía has exhibited at Genera, the International Trade
show of Energy and Environment in Madrid, at which solutions were presented to va-
rious energy producer´s needs such as the eliminating any economic retributions risk,
along with the added value of being a partner with financial stability. Nexus Energie
was also present at the E-world show in Essen (Germany), a leading European trade
show regarding energy and water.

Efficiency Energy Services
Nexus Energía has always been committed to energy efficien-
cy and the use of renewable sources, both of which lead to
lower energy costs and contribute to a better environment.
As part of this commitment, Nexus Energía has created MIA
(Intelligent Assisted Measure), a service that allows consumers
to view detailed information about their consumption from any
computer, so they know how and when to consume and thus
reduce their electricity bill. In 2012, MIA was improved and now
includes a reactive power alarm system that alerts clients via
email so that they can take appropriate action and avoid incu-
rring penalties.
In addition, Nexus Energía has also launched the Anti-reactive
Pack, a service that aims to eliminate reactive energy penalties
and goes beyond monitoring and alarms. It includes the ins-
tallation and maintenance of the required equipment without
any additional investment required by the client.
In 2012 Nexus Renovables acted as energy manager for 150
apartments with a centralized heating and hot water (DHW)
systems, thanks to renewable and high efficiency energy ge-
neration systems, such as micro-cogeneration and solar ther-
mal energy. It has also promoted biomass as an alternative to
fossil fuels and hopes that in the course of 2013, a new pe-
llet manufacturing plant in Caldes de Montbui (Barcelona) will
be brought into service. Likewise, Nexus Renovables provides
thermal biomass facilities, taking care of the design, installation
and even financial funding, through an electricity sales con-
tract (Energy Services Company).
In 2013, Nexus Renovables expects more progress in all projects
related to energy self-consumption through renewable sources
and the electric car. The company is convinced that while these
projects may face expansion and development barriers at the
moment, they will potentially represent a very important and
relevant part of our business in the future.
In conclusion, Grupo Nexus Energía continues betting on ener-
gy efficiency and renewable energies.
Nexus Renovables offers the opportunity to reduce one’s
electricity bill while helping the environment.
What do we do?

10. Annual Report 2012
Innovation
Nexus Energía is constantly aware of market changes,
anticipating the future in order to give clients an optimal offer.
The electricity sector in 2012 was subjec-
ted to significant regulatory changes, par-
ticularly in the field of renewable energies
with laws like RD 1/2012 which suspended
premiums for renewable energy, or RD
15/2012, which implemented a new tax rate
for electricity generation.
The innovations carried out in recent years
have been very well received, and have sin-
ce been further developed. A good exam-
ple of this is the Control Center approved
by Red Eléctrica of Spain (REE), which in
2012 connected to more than 10,000 plants,
PPS (Solar Price Protection), which offers a
guaranteed price to minimize uncertainty
for photovoltaic producers, and Toll Ex-
press, which automates Toll payments to
the Distributor. In 2012 Nexus Energía ini-
tiated a series of courses on topics of inter-
est in the electricity sector using knowled-
ge acquired by our professionals through
more than 10 years of experience. The
courses are aimed at consumers, produ-
cers, plant managers, energy consultants,
purchasing managers, installers, journa-
lists, and investors, and have been very well
received by participants. These help indi-
viduals with their work and optimise
their results by provi-
ding a better unders-
tanding of key aspects
within the sector.
Given the current situa-
tion it is expected that
regulatory changes will
be continuous throughout 2013. Nexus
Energía is constantly attentive to changes
in the sector, anticipating them whenever
possible and always with the aim of res-
ponding to clients, offering solutions to
facilitate plant operation and the energy
management of consumers.
On the other hand, interdisciplinary teams
have been created to assess new oppor-
tunities like self-consumption or net me-
tering, power generation under
the Ordinary Regime
through renewable ener-
gy, or the electric vehicle.

11. 9page.Innovation / Corporate Social Responsability
In 2012, Grupo Nexus Energía undertook
various actions and was particularly sen-
sitive in those areas where the economic
situation is proving particularly hard.
The Group strengthened its policy on pro-
moting CSR activities focusing on those
which, bearing in mind our core business,
can contribute more; such as the messages
introduced throughout 2012 on our bills to
help customers reduce energy consump-
tion or encourage the use of online billing
to save paper and reduce CO2 emissions.
To achieve this a specific campaign was
carried out as well as including messages
on the bills to further promote such mea-
sures.
However, actions such as donating paper
to cover the urgent needs of disadvanta-
ged areas and actively collaborate with the
Red Cross in collecting food, toys and hy-
giene products, have also been included in
the RSC plan.
On the other hand, internally, the Group
has launched an ambitious training plan to
help employees feel comfortable in their
jobs, increasing their knowledge and skills.
It has also taken steps to reduce the num-
ber of hard copies produced in order to
reduce waste as well as increasing aware-
ness of recycling and thermostat levels to
help the environment.
Corporate Social Responsibility
Grupo Nexus Energía continues to work towards setting a
great example and being a benchmark for society.

12. Annual Report 2012
Net sales increased a 2.7% compared to the previous year and remained
close to €900 million.
Relevant Data
Grupo Nexus Energía, at the financial year-end 2012, is comprised of 17 companies, located between Spain and Germany, among
which are Nexus Energía, S.A., Nexus Energie, GmbH, Nexus Green, GmbH, Nexus Renovables, S.L.U., Axon Time, S.L.U. and Energías
Intensivas, S.L.
The Group’s main activities focus on the sale of
electricity and gas, as well as in representing
producers in the wholesale electricity market.
Net sales increased 2.7% compared to the pre-
vious year and remained close to €900 million.
The number of employees as of December 31
was 238.
Consolidated Turnover Growth
The graph shows the spectacular growth of Grupo Nexus Energía that
went from €19.3 million in 2006 to €871.8 million in 2012, a 45-fold in-
crease in turnover in just six years and in the midst of an economic crisis.
Annual Report 2012
871.8

13. 11page.Relevant Data
The most significant figures are the following:
A remarkable fact of 2012 is that, despite the difficult financial climate, the turnover consolidated with an increase in gross margin, from
3% to 4%, and an increase in EBITDA as well.
Also worth noting is that the subsidiary Nexus Energie GmbH has changed its way of purchasing the energy to supply to its customers
over the coming years. Specifically, it has gone from buying through physical bilateral contracts with partners to making the purchase
through financial derivative contracts. The valuation of these derivatives at the end of 2012 has been negative due to a downward trend
of future prices, which has affected Grupo Nexus Energía’s consolidated result. If the previous purchasing system had been maintained,
the Profit after tax would have been €1.5 million.
This assessment will be largely reversed during 2013. For now, the results of the first quarter are very encouraging, as shown in the sec-
tion “After year-end closing” of this annual report.

Internationalization
During the 2012, Nexus Energía successfully began its business
in the Portuguese retail market, benefiting its current customers
located in Spain who have a presence in Portugal.
The exchange of energy between Spain, France and Italy is con-
ducted through interconnections between borders by favouring
all parties to improve the safety of their domestic power systems
and offering economic opportunities to sell or buy energy at com-
petitive prices. Seizing the opportunity that this situation offers,
the activity in the French market begun through the French-Spa-
nish interconnection. This has led to important economic benefits
and interesting business developments during 2012.
Leaping forward in the strategic process of international expan-
sion, Grupo Nexus Energía got a license as wholesale market ope-
rator in Italy and actively began taking part as an energy provider.
The Italian market is interconnected with the French one allowing
a large amount of power transmission which financially benefits
both markets.
In this way, the company ended 2012 expanding the activity at
a European level, with a presence in the international markets of
Portugal, France and Italy, as well as in the German electricity
market through our subsidiary Nexus Energie GmbH, and its new
headquarters in Düsseldorf.
The Grupo Nexus Energía trades in the Spanish, German, Portuguese, Italian, and
French wholesale markets, as well as the retail markets of the first three countries.

After year-end closing
After the year 2012, in which there was an intense reorganization of the different areas of the com-
pany, bridging gaps and optimizing processes, the year 2013 has begun at a very good pace.
Specifically, at the time of writing this document, we anticipate a good first quarter, with
results yielding a consolidated EBITDA of €2.4 million and pre-tax profit of €1.8 million. If
this trend is maintained in the coming months, we can be optimistic about the outcome
of the year.
