Figure 2 and 3: Site of CC SANTURTZI CCP
SANTURTZI CCP has one unit in operation 2, Group 4, based on combined cycle technology with
a net capacity of 396.40 MW. It has been operating commercially since 03/01/2005.
The operation of the combined cycle generator is based on the integration of two types of circuit
at different temperatures: an open gas-air circuit and a closed water-steam circuit, for the
generation of electric power by turning the thermo-dynamic energy of the fluids into mechanical
energy (in the turbines), which is then turned into electricity. The process is described in the
following process diagram:

On 30 September 2013, after completion of decommissioning work and a visit by the Biscay Minister of Industry, a Decommissioning
Certificate for the Santurce Thermal Power Station, Groups 1 and 2, was obtained.

Figure 4: Electrical generation process at SANTURTZI CCP
The main plant components are:

Gas turbine, powered by the combustion of fuel (mainly natural gas, but diesel oil in the
event of emergency).

o
The natural gas is supplied by the ENAGAS gas pipeline.
o
The combined cycle plant has a 1,000 m³ diesel oil tank.
Heat recovery steam generator, that produces steam from the heat of the gas turbine
exhaust gases.

The steam turbine, which converts the energy from the steam produced in the boiler into
mechanical energy.
The exhaust steam from the steam turbine is condensed in the condenser and the water
(condensed steam) is recirculated to the heat recovery steam generator, where the cycle
begins again. The cooling required by this process is carried out using sea water in an
open circuit.

The alternator then converts the turbine rotation into electrical energy, which is converted
to 220 kV in the transformer and sent to the mains grid.

Like any other industrial activity, the consequences of electricity generation have a potentially
adverse impact on the environment. SANTURTZI CCP controls this impact and tries to minimise it
by adopting preventative and corrective measures, and by streamlining its production systems.
The following figure shows the production of electricity at SANTURTZI CCP in MWh during the
period between 2006 and 2013:

It should be noted since 2010 SANTURTZI CCP has drastically reduced production, and in 2013
it was only in operation for one day to produce electrical energy. Two FSNL (full speed no load)
start-up tests were also conducted.
The organisation of personnel at SANTURTZI CCP is meant to achieve safe and efficient
operation of the facility's production processes while minimising environmental impact and
guaranteeing the safety of personnel.
To achieve this, the personnel is organised with the following block structure:

Operation: responsible for operating the facilities and the production process

Maintenance: responsible for maintaining the facilities in correct order and resolving any
anomalies that may arise

Plant engineering: responsible for supporting the facility's planning and management
processes

ENVIRONMENTAL ASPECTS
5.1.
Identification of Environmental Aspects
SANTURTZI CCP has a series of associated environmental aspects, defined as those elements
of their activities, products or services that can have an impact on the environment.
Environmental impacts involve any change in the environment – whether harmful or beneficial –
wholly or partly caused by the activity of SANTURTZI CCP. Significant aspects are considered
to be those that have or could have a significant impact on the environment.
As provided in procedure 2000-CC1-PG-017 “Environmental Aspects” of the SIGEC for Thermal
Generation, valid for 2013, SANTURTZI CCP has identified direct environmental aspects as
those over which it has direct management control under normal operating conditions or in
emergency situations caused by discharge or fire. The consideration of indirect environmental
aspects is also given to those over which a reasonable degree of influence can be exercised, but
which cannot be completely controlled.
At SANTURTZI CCP environmental aspects are identified and reviewed whenever any of the
following circumstances arise:
Page 11 of 37
2013 ENVIRONMENTAL STATEMENT SANTURTZI CCP

Introduction of new legal or regulatory requirements

Design changes/new operational methods

Implementation, modification, or shutdown of any activity, product or process

Change in the nature of the raw materials

Occurrence of an environmental event or incident.
Similarly, environmental aspects are reviewed annually even if none of the preceding
circumstances occur.
An assessment of the environmental aspects corresponding to 2013 has been made, adapting it
to the new location due to the dismantling of Units I and II of the Santurce Thermal Plant The
result of the assessment of 2013 environmental aspects has not changed compared to the
assessment conducted in 2012. Only some aspects related to the decommissioning of Groups I
and II are no longer present.
5.2.
Evaluation of Environmental Aspects
For each of the situations identified in the previous section, different assessment methodologies
have been established, and a hierarchical system has been defined for classifying
environmental aspects as significant or not significant. Some of the objectives of the
Environmental Management Programme are established according to this hierarchical
classification.

ENVIRONMENTAL MANAGEMENT PLAN
Annually and based on the general target set by Thermal Generation, SANTURTZI CCP, through
COCAL, which involves the managers from the various departments of the plant's organisational
structure and in which all employees are represented, draws up an Environmental Management
Programme that includes the specific goals and targets for the facility, the planned activity
schedule, the parties responsible for the actions that are planned, and the human and financial
resources to execute the planned actions. In order to establish the objectives and goals, the
significant environmental aspects and the applicable legal requirements, as well as other criteria,
are taken into account.
The assessment of the 2013 objectives is favourable. All the set objectives were met.
The last follow-up performed in 2013 is detailed below, including all actions carried out as well as
the degree of compliance with each objective evidencing the plant’s environmental behaviour.
Page 16 of 37
2013 ENVIRONMENTAL STATEMENT SANTURTZI CCP

The objective has been achieved: to achieve 0 ENVIRONMENTAL EVENTS and reach at least a 95% degree of progress in
ENVIRONMENTAL actions defined in the 2013 ENVIRONMENTAL ACTIONS PLAN. All goals have been met 100%.
In order to meet the objective of installing a smaller air compressor, initially a system cooled by water from the plant was to be installed, and a
connection was prepared for this. However, due to the decommissioning of CT Pasajes an air-cooled compressor became available (which
further improves auxiliary consumption) because the compressors which were to be installed were needed in Pasajes until the end of the year,
and had not yet been installed.

ENVIRONMENTAL INDICATORS
SANTURTZI CCP performs a follow-up on environmental efforts in order to check compliance
with current applicable legislation and also its Environmental Management Programme.
The general status of SANTURTZI CCP during the period of 2006 to 2013 is summarised in the
following sections. These involve monitoring the indicators significant to the organisation, making
it possible to quantify and notify their environmental behaviour and perform annual comparisons
of the data. In order to calculate the basic indicators included in Annex IV to EC Regulation No.
1221/2009, the gross production unit has been used as figure B to adapt them to the
organisation's activity, gross electricity production, given in MWh.
It should be noted that in 2013 in following with the trend for previous years, there was a sharp
drop in production which led to a significant increase in the value of the indicators for this this
year, making the values not useful for comparison to those obtained in previous years.
7.1.
Emissions into the Atmosphere
SANTURTZI CCP has gas emissions derived from combustion in its gas turbine identified as an
environmental aspect.
The Combined Cycle plant monitors the emission of sulphur dioxide (SO 2), nitrogen oxides (NOx),
particulate and carbon monoxide (CO)3. The limits imposed on these are stipulated in the
Integrated Environmental Authorisation (AII).
The control of SO2, NOX, CO, and particles are monitored constantly using two automatic gauges
installed in parallel in the chimney, and the signal from one of them is sent to the plant control
panel. This prevents loss of data during maintenance work or when one of the units malfunctions.
These gauges are checked and calibrated regularly in order to ensure that they work properly.
The monthly emission reports, as well as the calibration certificates for the metering equipment,
are sent to the competent authorities.
CO2 emissions are calculated monthly on the basis of fuel consumption (according to the specific
procedure "Monitoring and notification of greenhouse gas emissions"). They are verified annually
by an accredited body (AENOR) and compared with the specific assignment of emission rights for
the cycle, defined in the National Assignment Plan.
3
The AAI does not establish any legal limit for this parameter, only its control by measurement.
Page 18 of 37
2013 ENVIRONMENTAL STATEMENT SANTURTZI CCP
SANTURTZI CCP also calculates the emission of CH4 and N2O, also based on fuel consumption.
During 2013, the emission of CH4 and N2O, expressed in equivalent tonnes of CO2, represented
0.18% and 0.68 % of total greenhouse the plant's gas emissions, as shown in Section 7.1.4.
As far as other greenhouse gases are concerned, such as HFC, PFC and SF6, only the latter is
present in some high voltage electrical equipment, on which checks are made for leaks in
accordance with current legislation, but data on emissions into the atmosphere is not calculated.
The following graphs show total PAI4 emissions (tonnes) and specific emission (total emission by
energy unit produced, t/MWh) of the SO2, NOX, particles and CO2, parameters in the 2006-2013
period. Total emission directly depends on the consumption of fuel, and this, in turn, on the gross
energy produced, which is why the specific emission indicator enables its environmental
behaviour to be quantified in relation to atmospheric emissions, as well as compared to annual
data:

PAI are the periods to be reported according to ITC/1389/2008 Order dated 19 May, regulating the procedures for determining the
emissions of the air pollutants SO2, NOX and particulate from large combustion facilities, the control of metering equipment, and the
processing and sending of the information relating to these emissions.

Graph 3: Comparison of SO2 emission data.
The modification of the Integrated Environmental Authorisation at the end of 2012 did not
establish a legal limit for SO2 natural gas fuel emissions.
It must be considered that the SO2 emitted depends basically on the sulphur in the natural gas
used as a fuel, which has not changed.

Graph 5: Comparison of NOX emissions with the legal limit.
As can be seen, at no time in 2013 was the legal limit for NOX exceeded.
We can see that the concentration of NOX in emission gases has not changed with respect to
previous years, however the tonnes emitted have been considerably reduced as a result of a
reduction in gross production.
7.1.3. Particulate emissions
Due to the absence of particles in the emissions from natural gas combustion, the Integrated
Environmental Authorisation does not establish a legal maximum value for particles for this fuel.
The controls for the 2006-2013 period show no emission of particles: 0 tonnes of total emission
and therefore, 0 tonnes emitted per unit of gross energy produced.
7.1.4. Greenhouse gas emissions
Below follows the emission of greenhouse gases. The values of t shown equivalent to CO2
correspond to the sum of CO25+N2O+CH46.
5
The calculation of the emission of CO2 is performed as indicated in Decision 2007/589/CE of 18 July 2007 establishing guidelines for
monitoring and reporting of greenhouse gas emissions according to Law 1/2005, of 9 March, which regulates the trading of
greenhouse gas allowances.
6The emissions of CH4 and N2O were calculated based on the plant's fuel consumption for each natural year and applying the
emission factors recorded in the latest National Inventory of Emissions to the Atmosphere: Thermal Power Plant Sector, published by
the Ministry of the Environment. The tonnes of CH4 and N2O calculated are converted into equivalent tonnes of CO2using the
atmospheric heating potentials published by the Intergovernmental Group for the Climate Change in the Directives of the IPCC for the
national greenhouse gas inventories (IPCC Fourth Assessment Report: Climate Change 2007 (AR4)).

Discharges
The SANTURTZI CC plant performs periodic control of its waste, making sure at all times that it
does not exceed the limits established by current legislation and its Integrated Environmental
Authorisation.
The discharges of the combined cycle process are processed in the installation’s effluent
treatment plant (V1). The plant's operation is based on a physical and chemical purification
process: effluent pH adjustment and elimination of solids in suspension by coagulationflocculation, a process by which sludge is extracted, then dried and sent to the waste manager.
The open circuit cooling waters discharge (V2), which uses seawater, is returned directly into the
sea via a discharge mechanism that continually checks for the presence of free chlorine and for
increases in temperature.
Page 22 of 37
2013 ENVIRONMENTAL STATEMENT SANTURTZI CCP
Lastly, waste coming from water potentially contaminated with hydrocarbons (V3) is treated by a
process of separation and filtration prior to discharge along with the rest of effluent at the Point of
Discharge (PV1).
The site has one single authorised discharge point through which all its effluent is passed. This is
located in the outer sea wall of the outer dock of the port of Bilbao. This is shown in the following
pictures:

Table 8: Hazardous waste generation.
The following shows the Hazardous Waste Minimisation Plan for the period 2013-2016 as
presented by SANTURTZI CCP in July 2013. The plan contains the measures proposed for
reducing the waste identified as suitable for improvement, together with a quantification of the
anticipated annual targets for the reduction. Given that the minimisation plan is a four-year plan,
the average of the last four years is taken, together with the target for the next four years for the
waste generated per unit of production at the site (kg/GWh).
Target: Reduction of 5% in weight of the average production value of “Absorbents and textiles contaminated
with hydrocarbons” (from 3.204 Kg/GWh to 3.044 Kg/GWh).

Graph 9: Energy consumption evolution
During a stoppage, it is not possible to determine the origin of the electric power absorbed from
the supply network by SANTURTZI CCP because there is no information that makes it possible to
calculate the "total consumption of renewable energy" indicator. When the plant is in operation,
the power consumed is thermal in origin and originates from the plant itself.
The following indicates the change in the energy efficiency indicator that compares the total
consumption of energy resources with SANTURTZI CCP electrical energy production over the
2006-2013 period:

Graph 10: Annual energy efficiency evolution
The increase of this indicator in 2013 shows the worsening of the energy efficiency of the plant
since the total gross production dropped and the plant's essential equipment continued to
consume electric energy from the grid while it was stopped.

It should be noted that although sulphuric and caustic acid were not consumed due to the lack of
operation, ammonia was consumed when the auxiliary and main unit boilers were started.
7.4.3. Water Intake
As well as the sea water used in the cooling circuit, all of which is returned, the cycle needs fresh
water to carry out its production activity. This is provided by the Water Consortium of Bilbao,
Biscay.
The main consumption of water in the cycle corresponds to the need for demineralised water in
the water-steam cycle.
