The substation will allow Enel Green Power to deliver renewable electricity from Brazil’s largest photovoltaic power plant in a safe, reliable and sustainable manner.

When ABB delivered the first digital substation in Latin America, Brazil 2018, the news did not go unnoticed. Enel Green Power, a world leader in renewable energies, has decided to digitize its resource and process management to improve energy efficiency, reduce maintenance costs and increase the use of sustainable solutions. Better accessibility to plant data enables faster decision-making and real-time solutions to address inequalities in energy produced by solar radiation due to climatic factors.

With that in mind, ABB’s digital substation seemed like the perfect solution. In close collaboration with the customer, ABB offered several design and engineering alternatives to find the solution that would meet the technical and economic requirements of Enel Green Power.

Decarbonization of the largest photovoltaic power plant in South America.

ABB’s substation was chosen by Enel Green Power to supply clean solar power to the Brazilian 500 kilovolt (kV) grid from the São Gonçalo solar photovoltaic power plant in Piauí, in the northeast of Brazil. country. It is the world’s first 500 kV AC digital substation.

The first part of the 475 MW plant entered service last January. When completed, it will be able to generate over 1,200 GWh of clean solar power, reducing more than 600,000 tonnes of carbon emissions per year.

Photovoltaic energy is booming in Brazil. The installed capacity will reach 3000 MW by the end of 2020, which represents an increase of 50% compared to 2018. According to ABSOLAR, the Brazilian association of the photovoltaic industry, this represents an investment of 1300 million dollars in the country’s economy, which translates into 15,000 jobs. Given the situation, electricity distribution network operators today need digital solutions to cope with the growing amount of renewable energy, by nature intermittent and distributed, to be integrated into the network.

What is a digital substation?

ABB’s digital substations offer customers increased control and reliability. They collect data to continuously transmit information about operations and asset health, enabling faster and more reliable decision-making. They help simplify the application of predictive maintenance strategies based on asset health through the application of remote diagnostics and services. By using optical fibers instead of copper cables, ABB technology enables safer substation operations, shorter installation times and lower total cost of ownership.

ABB delivered the world’s first digital substation in 2009. Since then, it has supplied more than 30 to utilities and industries around the world.
