Context
Chile is enjoying a strong economic growth and the power consumption has doubled every 10 years. Construction of additional conventional thermal power plants and increasing consumption of fossil fuels such as coal are resulting in an increase in greenhouse gas (GHG) emissions. With Chile’s accession to the Organization for Economic Co-operation and Development (OECD), the country made a commitment to mitigating climate change and announced ambitious GHG reduction goals. The objective of Chile's energy policy is to ensure security of supply at competitive costs considering climate protection criteria. In this endeavor, renewable energy resources are becoming more and more important. In 2008, the quota law for renewables established a basis for their integration into the market. Due to their optimal solar irradiation conditions, Chile has one of the highest solar potentials worldwide. Now, the Chilean Government additionally wishes to promote the use of solar energy.
In order to encourage market development, the Ministry of Energy has implemented the following measures:
- Tax incentives for the use of solar thermal water-heating (solar thermal energy)
- The Net-Billing,law for feeding in self-generated electricity from systems delivering up to 100 kW
A start has been made in setting up large scale solar power plants in the north of the country, and the electricity generated through solar energy is competitive compared to the conventional energy generation. Nevertheless, various obstacles, especially for small size installations, have prevented a wider use of solar energy. There are only a few suppliers of PV systems for captive use, and there is also a shortage of qualified specialists. Consequently, the prices for solar installation are still at a high level in comparison with the international market, and the technologies used are not attractive for financial institutions. Banks are cautious when it comes to financing small sized projects and self-consumption system, and there are gaps in the regulatory framework.
Approach
The project “Solar energy for the production of electricity and heat” from the Deutsche Gesellschaft für Internationale Zusammenarbeit(GIZ) GmbH, supports the Chilean government under the framework of the International Initiative for Climate Protection (IKI), in achieving their goals of reducing Green House Gases (GHG), opening profitable market segments for the use of solar energy.
The first stage involved an improvement of the framework conditions for the installation of such a technology. Innovative business models are being developed for each sector, and installers are being trained in order to strengthen local skills and thus, foster new markets for the use of climate-friendly solar energy technology. The work of the project is located at the intersection between the solar market and energy policy.
Market opportunities for self-supply solutions
The project allows the identification of economic sectors and scopes of application in which the captive use of solar power and solar heat for self-supply is economically viable. The insights gained within the scope of project activities are continually factored into the policy advice for use in developing an enabling environment, and are intensified by means of fact-finding tours, workshops and the exchange of information and experience in a national and international level between solar sector actors.
Results
Regulatory Framework
Support to the Ministry for the Completion of the Regulatory Framework and Dissemination of the Law for Distributed Generation (Net-Billing / Metering)
The Project participated in the completion of the regulations and technical standards for the distributed generation law. Furthermore, it yielded valuable impetus in the diffusion through a video and a website explaining the operation and administrative processes for connecting an electrical generator under the distributed generation law.

Manual for Fire Prevention in PV Power Plants
The document is about the evaluation of fire risk in photovoltaic systemsand creation of security conceptsto minimize risk. Content of the review is:
- The evaluation of fire risk in PV power plants, as well in case of action of third parties as fire risk occurring within the PV power plant.
- Evaluation of risks for fire fighters in case of fire fighting and developing and demonstrating strategies to minimize risks.
- Evaluation of options to minimize fire potential within the PV power plant.
- Derivation of recommendations conceerning components and system design, material and quality assurance concerning production, installation and maintenance.

Market Development
Identification of “Zona de Foco” Highly Profitable for the Photovoltaic Self-consumption
The geographic areas with the most cost-effective conditions for the captive-use of PV installations were identified, taking into account the solar irradiation and the electricity tariff as main variables for the profitability.

Uploading Solar Radiation Database of Chile in PV*Sol Software
Explorador Solar is a tool of the Ministry of Energy and the Department of Geophysics of the University of Chile in Santiago which gives information about solar radiation for a specific geographic location in Chile and allows simulating a PV-system.
Although Explorador Solar is able to determine the potential, the azimuth and the inclination of the PV-system, it does not allow to design the general system. Therefore this needs to be done with another software - i.e. PV*Sol. Following on this, GIZ has developed an Excel tool which converts .CSV files of Explorador Solar into a .DAT file (format required for PV*Sol) for a specific location in Chile. The converted data file (.DAT) can be uploaded into PV*Sol. By doing so, it is possible to design a PV-system by using Explorador Solar's database. The following two documents will help with these steps.

Expected Impacts
The use of solar energy can partly replace electricity generation in conventional power plants, which contributes to achieving the goals of reducing emissions and energy dependence in Chile. A more sustainable and secure energy mix contributes to improving the international competitiveness of the Chilean economy.
