Artificial intelligence (AI) is revolutionizing the global economy, but it brings a challenge: the need for data centers capable of operating with high availability, efficiency, and sustainability. Solar energy and battery energy storage systems (BESS) can be the combination that defines the future of these data centers.
According to the International Energy Agency (IEA), the electricity consumption of data centers is expected to exceed 945 TWh by 2030, more than double the amount recorded in 2024. It is expected that a large part of this growth will be met by renewable sources, especially solar and wind energy. In Brazil, which has one of the cleanest energy matrices in the world, solar energy can be a pillar of this transformation.
1. What is the role of solar energy in AI data centers?
Solar energy is a renewable source that can help reduce the cost of electricity generation and contribute to decarbonization goals. However, solar generation depends on sunlight throughout the day, while data centers operate continuously. This is where battery energy storage comes into play, allowing the accumulation of energy produced during periods of higher solar generation for use during periods of higher consumption.
Imagine a restaurant that operates 24 hours a day. It needs a reliable source of energy to maintain its operations. Solar energy can be an option, but battery energy storage is necessary to guarantee energy supply during the night or on cloudy days.
2. How can battery energy storage help?
Storage systems allow the accumulation of energy produced during periods of higher solar generation for use during periods of higher consumption or when production decreases. In addition to increasing the reliability of the supply, these solutions reduce oscillations, expand the stability of the electrical grid, offer greater operational predictability, and enable more efficient integration of renewable sources.
An example of this is the battery energy storage project with a capacity of 120 MW, structured for participation in the Reserve Capacity Auction (LRCAP), with a connection planned in Bom Jesus da Lapa (BA). The choice of region is strategic, as the substation is considered a critical point in the National Interconnected System (SIN).
3. Why is the combination of solar energy and storage strategic for Brazil?
Brazil has one of the cleanest energy matrices in the world and has privileged conditions for expanding its renewable generation. The combination of an abundance of natural resources, growth of the free energy market, and expansion of the transmission infrastructure can transform the country into one of the main global destinations for new investments in digital infrastructure.
The energy infrastructure will increasingly be one of the main factors in determining which countries will lead this new stage of technological transformation. The combination of solar energy and battery energy storage can be a strategic pillar for economic development, innovation, and global competitiveness.
