2. The “Concentrating Solar Power project”
► The demonstration plants aim at assessing in real operating conditions, the
feasibility, the performance and the reliability of small-scale concentrating
solar power (CSP) technologies (P<5MWe ) in the field of distributed generation
► The capability of small scale CSP with thermal energy storage to supply
programmable and dispatchable electricity and thermal energy at local level
will be investigated
Within the Concentrating Solar Power (CSP) project, funded by the Regional
Government of Sardinia in the framework of the operational programme ERDF
2007-2013, demonstration plants, based on CSP technology, will be designed and
built in Sardinia.

3. Projects Objectives
The main goals of the project are as follows:
 investigating the feasibility, performance and reliability of small scale
CSP with thermal energy storage in integrating distributed generation
systems
 improving the programmability and dispatchability of electricity
generation, through the integration of CSP plants with systems for thermal
energy and electricity storage.
 assessing the integration of small-scale CSP technology with other
renewable energy systems
 enhancing the know-how on control algorithms used to improve both
programmability and dispatchability of renewable energy generation, with
the aim of fostering the future development of smart grids
 evaluating the opportunity to replicate project results in Sardinia as well
as in other Mediterranean areas.

4. Attractive features of the CSP Project
 It can be easily adapted to the characteristics of Sardinian territory (and Italian in
general)
 It is in line with the policy of the Regional Government of Sardinia to promote
distributed generation from RES to meet the local thermal and electrical demand
 Interesting potential of economic benefit on the regional territory: supporting new
local industries devoted to CSP components and technology development
 Possibility to use the small-scale CSP technology for applications in solar
heating and cooling for industrial processes, especially in the agri-food sector
 The size identifies industrial demonstrators and not only pilot plants: will be
relevant to gain information about real plant performance and increase the
confidence in the technology by means of plants operation
 Ideal conditions for smart microgrid and storage testing
Advantages of small-scale CSP technology:
 Integration of CSP in microgrids for distributed energy generation

9. Governance
The projects are supported by European Union ERDF 2007-2013, Asse III,
Energia (Linea di Attività 3.1.1.c).
The institutional supervisor of the project is the Industry and Energy
Department of Regional Government of Sardinia
The coordinator of research activity is Sardegna Ricerche, which will
manage the start-up and the experimentation, with the contribution of
the University of Cagliari, and will monitor and disseminate the results
Sardegna Ricerche provided technical and scientific support to the
project partners during the design phases of the CSP plants
The operation of the demo plants will be in charge of:
 ENAS, the Regional Water Network Operator (Ottana)
 Provincial Industrial Consortium of Medio Campidano Villacidro

12. Other Activities and Dissemination
ѻ Associated Partner of the FP7 European Project InSun which aims to study the
integration of solar plants in industrial processes at medium and high temperature.
Sardegna Ricerche is supporting the studies concerning the application of the CSP
technologies in the cheese making sector due to its strategic impact at regional level
ѻ Member of the Task 49 for Solar Heat Integration in Industrial Processes in the
framework of Solar Heating and Cooling program (SHC) of the International Energy
Agency (IEA)
ѻ Scientific papers and presentations at International Conferences on the main research
topics of the projects (ATI 2014, SolarPACES 2015, ICRERA 2015, SHC 2015)
ѻ The CSP group of Sardegna Ricerche carries out dissemination activities to promote
the use of CSP technologies as distributed systems for electricity and thermal energy
production and it also applies for research project at European level (Horizon 2020)

13. Future Activities
ѻ Analysis of test procedures and acceptance criteria, and research studies on
methodologies for the evaluation of solar collectors and solar field operating performance:
lack of international standards and specific regulations
ѻ Technical support to ENAS during testing and commissioning of the Ottana Solar
Facility
ѻ Experimental and monitoring activities on the Ottana Solar Facility
ѻ Definition of methodologies to uniform test procedures and acceptance criteria, and
assessment of innovative components
ѻ Technical support to Industrial Consortium of Villacidro for the realization of the
Villacidro Solar Demo Plant
ѻ Analysis of possible integration strategies of small scale CSP plants with existing
industrial process at local level (focus on agri-food industry sector)
The demo plants realization will have a strategic importance for the Sardinia Region
because they will be a demonstrative platform to carry out research activities and to develop
testing and experimental activities, encouraging the cooperation at European level and
the technology transfer to the Sardinian enterprises
