However, the law could not become effective before 23<sup>rd</sup> October 2014 due to the lack of implementing regulations and technical standards. The “Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) GmbH” supported the working group of the Chilean Ministry of Energy and the regulator (CNR) in developing the necessary implementing regulations and technical standards. The "Norma Técnica" is based on the German standard VDE-AR-N 4105, and considers the German experience with feeding electricity into low and medium voltage grids.<br/> | | With the adoption of the '''Law 20.571 '''for Net-Metering/Billing in February 2012 the course for the integration of electricity from distributed renewable generation was set.

The aim of the law is to provide electricity customers with the right to generate and consume their own electricity and to feed exceeding electricity into the grid. The law only applies for tariff-regulated customers whose connection power is below 2 MW. The following is a summary of the most important details of the law:
With the described regulatory framework, the Chilean Government has created the foundation for the development of a market for distributed generation. Over the next four years, in addition to providing the legal basis, the Chilean Energy Ministry "Ministerio de Energía" invest about 13 Mio USD (about 12 Mio €) in the construction of 250 to 350 photovoltaic systems on roofs of public buildings. During the implementation of the project the Ministry will be advised by GIZ. The investment program aims to stimulate the market for small photovoltaic systems, to disseminate information about the possibility of installing photovoltaic systems for self-supply, to optimize the existing standards and procedures, and last but not least to reduce electricity costs for the corresponding institutions.
