Detailed explanation of brazil s energy storage project

Can Utility-scale energy storage systems be used in Brazil?

Such challenges are minimized by the incorporation of utility-scale energy storage systems (ESS), providing flexibility and reliability to the electrical system. Despite the benefits brought by ESS, the technology still has limited investment and application in Brazil.

Does Brazil need energy storage regulations?

Specifically for Brazil, as shown in the results, there is no resolution that specifically addresses energy storage, even though some regulations currently in force may indirectly influence the adoption of ESS technologies, such as regulations for electric vehicles, differentiated hourly tariffs, among others.

How do energy contracts work in Brazil?

Another point that needs to be defined is the type of contract to be assumed in the energy storage market. Nowadays, the most used way of energy contracting in Brazil is regulated market auctions, considering the lowest tariff criterion.

How can ESS be economically viable in the Brazilian electricity market?

Some actions already implemented in the Brazilian electricity market, such as the hourly spot prices and the reduction of the minimum size required to access the free market, are considered necessary starting points in search of the economic viability of utility-scale ESS.

Is ESS a viable technology in Brazil?

Despite the benefits brought by ESS, the technology still has limited investment and application in Brazil. The financial viability of ESS, in the current Brazilian regulatory framework, is unlikely.

What percentage of Brazilian electricity is renewable?

Electricity generation in the country, in 2019, increased 4.1 % compared to 2018, reaching 626.3 TWh. Final consumption increased 1.3 % in relation to 2018, reaching 545.6 TWh . Renewable energy represents 83 % of Brazil's electrical matrix, as can be seen in Fig. 3. Fig. 3. Internal supply of Brazilian electricity by source. Source: EPE .
