On August 10, 2026, Greener published a retrospective article on the 18 editions of its study on distributed generation (DG) in Brazil. The survey has tracked the segment for nine years, and the main conclusion of the review is that DG is no longer a market focused solely on installing photovoltaic systems. Today, according to the publication, it works as an ecosystem that brings together energy storage, electric mobility, the Free Energy Market and digital services. For those working with batteries, this reading deserves attention: storage appears as a structural part of the sector's new phase.
A historical series spanning almost a decade
Periodic studies like Greener's are valuable precisely because of their continuity. By repeating the analysis over 18 editions, it is possible to see trends that do not show up in isolated snapshots of the market. The retrospective works as a narrative of Brazilian DG itself, told by those who recorded each stage of its expansion.
The central point of the text is the change in the nature of the business. In the beginning, distributed generation was practically synonymous with selling and installing solar panels on rooftops and small plots of land. As it matured, the segment came to encompass a broader set of interconnected solutions.
From solar panel to energy ecosystem
According to Greener, today's DG combines different fronts that were previously treated separately:
- Storage: batteries integrated into solar systems, making it possible to store generated energy and use it at another time.
- Electric mobility: vehicle charging begins to interact with local energy generation.
- Free Energy Market: the environment in which consumers negotiate supply contracts directly, outside the distribution utility's regulated tariff.
- Digital services: monitoring, management and operation platforms that add value to installed assets.
This convergence indicates that DG customers tend to seek complete solutions, not just a generation device. Storage, in this context, is the piece that connects several of these fronts, because it brings flexibility to the use of the energy produced.
Why storage is taking center stage
A battery energy storage system, known by the acronym BESS (Battery Energy Storage System), brings together battery cells, inverters and control systems capable of charging and discharging energy on a scheduled basis. Integrated into a solar plant, it makes it possible to shift energy from peak generation hours to peak consumption hours, reduce reliance on the grid at certain times and make operations more predictable.
When the DG market itself starts to include storage in its portfolio, as the retrospective points out, the battery stops being an optional accessory and becomes part of the standard offering of integrators and developers. This movement tends to expand demand for batteries coupled with photovoltaic systems across the country.
What changes in practice for the BESS market
Greener's reading has direct implications for those working in the storage chain in Brazil:
- Developers: DG projects start to be designed with storage from the outset, which requires assessing consumption profiles and battery usage strategies as early as the study phase.
- EPCs and integrators: expertise in hybrid systems, combining solar generation, batteries and control, becomes a competitive edge over companies that offer only photovoltaic installation.
- Manufacturers: there is growing room for products designed for integration with distributed solar systems, focused on compatibility and ease of installation.
- Service providers: the digital layer gains relevance, with opportunities in monitoring, energy management and remote operation of battery assets.
In short, the evolution recorded over nine years shows a more integrated sector. For the BESS chain, this means that the door into the distributed generation market is already open, and that the ability to offer complete solutions will be decisive in the next stage.
