Strategic
Guidelines
▶ Enlarging the installed generation capacity
▶ Balancing the sources mix from RE
▶ Pioneering new Business Models
▶ Spreading Sustainable Development culture
Ait Baha project consists in the realization of a concentrated solar power (CSP) plant having
the aim of validating the expected performance and checking the potential for additional and
new applications inside the Group.

Concentrating Solar Power (CSP) plants generate
electricity utilizing the solar energy
CSP plants consist of two main
parts:
▶ one that concentrate (focus) the
sunlight using mirrors and
convert it into high-temperature
heat and
▶ another that converts the heat
energy into electricity.
All CSP technological approaches require large areas for solar radiation collection.

Concentrating solar technologies exist in four common forms
Parabolic troughs
Fresnel reflectors
Linear parabolic
concentrators where
sunlight is concentrated
onto a receiver placed in
the trough’s focal line.
Parallel rows of mirrors
flat or slightly curved to
reflect the sun’s rays
onto a downward facing
linear receiver.
Concentrate the sunlight
on a receiver placed in
the focal point above the
centre of the dish.
Use thousands of small
reflectors to concentrate
the sunlight on a central
receiver placed at the top
of a fixed tower.

…with the scope to validate the performance of each single component
Mirrors
▶ concentrate more sun light
▶ easy to manufacture, transport and install
Structure Frame
▶ guarantee the right mirror shape
▶ predominant use of local available materials
Heat Transfer Fluid
▶ temperatures well above 600°C
▶ air is non-toxic and for free
▶ no dangerous or flammable fluids used
Heat Storage
▶ higher flexibility of power modulation
Higher

First, we identified the most suitable location and dimensioned the
plant…
 Among ITC Group available sites, we have identified Ait Baha (Morocco) as the best
opportunity in terms of land availability, solar irradiation and already existing infrastructures.
 The pilot plant consists of 3 solar modules and a new heat exchanger integrated in the
existing cogeneration system.

The heat captured through the solar modules will be added to the
one recovered by the thermal oil circulating in close contact with the
waste heat of the kiln hot gases.

Final Remarks
Next year Italgen will add to its portfolio the first CSP pilot plant, being in the position to record
data and make comparisons with technologies already exploited.
