  2. Project rationale ItalgenStrategic 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.

  4. 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. Source: Technology Roadmap CSP IEA 2010

  5. 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. Parabolic dishes Solar towers Use thousands of small reflectors to concentrate the sunlight on a central receiver placed at the top of a fixed tower. Concentrate the sunlight on a receiver placed in the focal point above the centre of the dish. Source: Energy Week - MIP - F. Frattini

  6. We are installing a solution completely different from the traditional... TRADITIONAL TECHNOLOGY Mirrors Flexible pneumatic Rigid Structure Frame Precast fiber reinforced concrete Metal Heat Transfer Fluid Air Synthetic oil, molten salt Heat Storage Gravel of basalt Molten salt

  7. …with the scope to validate the performance of each single component • concentrate more sun light • easy to manufacture, transport and install Mirrors • guarantee the right mirror shape • predominant use of local available materials Structure Frame Higher thermodynamic efficiency 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 Lower generation cost

  9. 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. K.P.I. Project Main Data • 2.5 hectares of occupied land • 3 solar modules (216 x 11 meters) • 6,055 m2 of total reflecting surface (less than a football field) • 6,400 MWh of net thermal production • 1,000 MWh of gross electric production • Less than 1 m3/day of water consumption (300 m3/year) • Land optimization (MWh/m2) • Maintenance (€/MWh) • Efficiency (%) • Dispatchability level (heq/y) • Production (MWh/y) • Water Consumption (m3/y)

  10. 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. Existing Cogeneration System New CSP plant 10
