Energy storage technologies – the key to the energy transition in Brazil (DKTI)

Project description

Title: DKTI – Brazilian-German Technology Partnership for Energy Storage
Commissioned by: Federal Ministry for Economic Cooperation and Development (BMZ)
Country: Brazil
Lead executing agency: Ministério de Minas e Energia (MME)
Overall term: 2020 to 2023


Brazil is at the beginning of a rapid growth in renewable energy. However, the supply of renewable energy, in particular solar and wind power, is not consistent, so relying on it causes fluctuations in the country’s electricity supply.

In order to counteract these fluctuations, storage technologies are needed that improve grid stability and security of supply. Currently, the most advanced and economically viable energy storage technology is battery storage. Therefore, the focus of the DKTI Energy Storage project is on the integration of battery storage into both On-Grid and Off-Grid systems. The successful use of energy storage technologies plays a central role in achieving energy and climate policy objectives.

Energy storage technologies also enable the interlinking of different areas of the energy sector, such as electricity, heat supply, transport, and the needs of the industry. A joint approach analyses potentials and optimises interlinking where it is already in application. Power-to-X technology, or in short PtX - the term for various processes and technologies for storing surplus electricity from renewable energy sources - is expected to make a significant contribution in the future.


The prerequisites for the widespread use of energy storage technologies to improve grid stability and security of supply in Brazil have been created.


The project advises political decision-makers, regulators, power utilities and grid operators on assessing possibilities and options of technical usage of energy storage and the creation of the necessary framework conditions. It also advises independent power utilities and grid operators in northern Brazil on planning and integrating energy storage in isolated power grids. Moreover, it supports governmental and private research institutions in Brazil in establishing cooperation arrangements and networks with international companies and conducting application-oriented research, with a special emphasis on partners from Germany.

The capacity development strategy of the project entails offering training courses and providing technical and policy advice that reinforce the broad-scale use of energy storage technologies in Brazil.

The organisational development measures improve tendering procedures, boost project funds and support the development of new service provision such as business and funding models. They also create interdisciplinary working structures, for instance in the context of research and development (R&D) projects, to establish networks of experts and promote the sharing of experience.

The project also carries out analyses and studies on topics such as technical utilisation options, costs and benefits of integrating energy storage, energy planning models, the use of grid storage technologies, and the integration of energy storage into the Brazilian electricity grid.
