4e Chile

The Program for Renewable Energies and Energy Efficiency (4E) is an initiative of the Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) GmbH on behalf of the Federal Ministry for the Environment, Nature Conservation and Nuclear Safety (BMU), the Federal Ministry for Economic Cooperation and Development (BMZ) and the Federal Ministry for Economic Affairs and Energy (BMWi) of Germany.


Since 2014, the 4e Program has been working in Chile to increase the sustainability of the energy sector by providing technical assistance, for example, to improve the regulatory framework, to promote new businesses and through project financing.

The Chilean Ministry of Energy is  the program’s counterpart in promoting initiatives for the use of renewable energies in companies, the development of a green hydrogen industry, decarbonization of the electricity matrix, cogeneration, energy efficiency and more.

Chile’s renewable energy potential as a huge opportunity

GIZ specializes in technical cooperation for sustainable development worldwide. In Chile, the energy sector is responsible for about 78% of the greenhouse gas emissions that cause climate change.

According to a study published in 2014 by the 4e Program, a potential of 1,800 GW in renewable energies was identified for Chile. This potential corresponds to about 75 times the current installed capacity of the country. Also, the Atacama Desert is the best place in the world for solar energy, with a radiation of up to 2,400 kWh/m2, allowing to achieve photovoltaic plant factors of over 45%.

These characteristics make Chile a paradise for renewable energies. Clean energy enables the country to be a regional forerunner in the energy transition. Adding to that, renewables enable Chile to be an energy exporter and develop new green technologies such as green hydrogen, concentrated solar power and pump storage.


Some of the projects developed to date have been the expansion of large and small-scale renewable energies and their integration to the grid, the development of energy efficiency projects in mining sector and the promotion of cogeneration in industry and commerce, in addition to a project initiated in 2019 that aims to promote the decarbonization of the Chilean energy sector.

Until January 2021 the 4e Program has carried out ten projects, five already finalized and five still in execution.

The digital, interactive model

The transition to a green economy is within reach as we experience a boost in the development of new renewable energy sources and green hydrogen.

Chile has enormous potential to generate electricity from renewable sources. According to different studies, the country has more than 1,800 GW of renewable power. If we consider that the current installed capacity of the electrical matrix is 25 GW, there is a lot of space for expansion of a new «green» and carbon-free economy.

In order to outline this potential, the project «Decarbonization of the Chilean energy sector«, financed by the German Federal Ministry of the Environment, Natural Conservation and Nuclear Safety, implemented by the «Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) GmbH» in cooperation with the Chilean Ministry of Energy, prepared a model that visually explains Chile’s path towards carbon neutrality and the great opportunity that Chile has to be a «green» and sustainable country in the future.

Ongoing Projects

Decarbonization of the Energetic Sector in Chile

This project aims to support the energetic transition of Chile, contributing to the electric system decarbonization through technologies for the reconversion of carbon centrals, promoting strategic themes like green hydrogen, the fair transition and increase the integration of renewables to the network.
