Energy of the Future: passive grids do not support the future.

In the first article of this series, I showed that energy storage ushers in a new era in the Brazilian electricity sector. But to fully understand this transformation, it is necessary to look at the foundation upon which the entire system operates: our distribution networks.

Today, they still operate as passive structures, designed to carry energy from large power plants to consumers. This model was sufficient for the last century, but it no longer meets the needs of a country that produces, consumes, and shares energy in an increasingly decentralized way.

Installing millions of solar panels without modernizing the grid is like putting thousands of computers in a city without internet. Distributed generation is growing at an accelerated pace, but the infrastructure that should integrate these resources remains limited.

The result is waste, inefficiency, and often, restrictions that prevent consumers from becoming the protagonists of the energy transition. It's as if we have the technology in our hands, but not the platform capable of connecting it.

The concept of OERs (Distributed Energy Resources) is central to this discussion. Solar panels, batteries, electric vehicles, demand response systems, microgrids, and even green hydrogen are examples of assets that can be integrated into the grid. But for this to happen, distribution needs to stop being just a wire that transports energy and transform into an intelligent exchange platform.

This change is comparable to what happened with telephony: before, we had landlines that only transmitted voice; today, we have digital networks that integrate data, video, applications, and services. Electricity is about to undergo the same revolution.

This transformation is not only technological, but also economic and social. A smart grid will allow any citizen to freely produce, store, consume, sell, and share energy. This democratizes access, reduces systemic costs, and increases resilience in case of failures or blackouts.

Instead of relying exclusively on large power plants, the system will now have millions of small power plants spread across the country. This is the transition from consumer to prosumer: one who not only consumes but also produces and actively participates in the energy market.

Brazil has a unique opportunity. Our electricity matrix is ​​already predominantly renewable, with a strong presence of hydroelectric, wind, and solar power. But the intermittency of these sources demands flexibility. Without smart grids, we will remain stuck in a model that wastes potential and limits expansion.

With modern grids, we will be able to integrate storage, demand response, and distributed generation, creating a more efficient, secure, and competitive system. This is the true modernization of the electricity sector.

It's important to emphasize that this change doesn't mean attacking distributors or regulators. It means recognizing that the world has changed, technology has changed, and the economy has changed.

Now, the electrical infrastructure also needs to evolve. Countries that understand this transformation will be better prepared to compete in the coming decades. And Brazil, with its clean energy matrix and industrial potential, can be among the leaders of this new energy economy.

The challenge is institutional. The technology already exists, the capital is available, and the manufacturers are ready. What is lacking is regulatory speed and strategic vision. We need rules that allow for the remuneration of ancillary services, the participation of storage systems in markets, the operation of distributed resource aggregators, and the creation of virtual power plants.

We need to transform distribution into a digital platform capable of integrating millions of assets and offering energy with freedom, efficiency, and low cost.

In the 19th century, railroads were the infrastructure that sustained development. In the 20th century, it was highways.

In the 21st century, the smart grid will be the key. This is the foundation upon which electric vehicles, artificial intelligence, data centers, smart cities, and Industry 4.0 will operate. Without modern grids, Brazil risks falling behind. With them, it can become a leading player.

That's why I argue that our electrical grids need to stop being passive. Because only an active, digital, and intelligent infrastructure will be able to sustain the energy of the future. And to understand how this transformation connects to storage, we need to look at the next step: showing that energy storage is much more than just a battery. That's what we'll discuss in the next article.
