Following the path opened by Open Finance, the Brazilian electricity sector is definitively entering the era of data portability. With the regulation consolidated by ANEEL (National Electric Energy Agency) in 2025, Open Energy will cease to be a concept and become the backbone of a decentralized, user-focused market.
The premise is simple, yet powerful: consumption data belongs to the customer, not the distributor.
Implementation timeline (roadmap 2025-2026)
The transition is structured around two fundamental interoperability milestones:
Impacts and vectors of transformation
Open data acts as a value catalyst on three fronts:
- For the Consumer: Empowerment in migrating to Mercado Libre, access to personalized efficiency services, and complete transparency regarding costs.
- For the Ecosystem (Energy Techs): End of information asymmetry. Possibility of creating "Energy as a Service" (EaaS) models and real-time tariff comparison tools.
- For the sector: Mandatory technological modernization of distributors and reduction of operational bottlenecks.
Global references: where Brazil finds inspiration
The Brazilian model did not emerge in a vacuum; it absorbed the best practices from mature markets.
- USA: Pioneers with the Green Button standard since 2012.
- United Kingdom: Holistic integration between energy and finance data.
- Australia and Portugal: Focus on decarbonization and residential/industrial efficiency.
Strategic challenges on the horizon.
For Open Energy to reach its full potential, the market must address four critical points:
- Infrastructure: Stability and robustness of APIs on a national scale.
- Security: Protection against cyberattacks (in accordance with the guidelines of Provisional Measure 1.300/2024).
- Financial Viability: Clear definition of how adaptation costs will be passed on.
- Inclusion: Bringing the benefits of digitalization to lower-income classes.
Conclusion: the birth of new markets
Open Energy is the necessary infrastructure for the emergence of solutions that were previously only theoretical in Brazil:
- VPPs (Virtual Power Plants): Aggregate management of batteries and distributed generation.
- Energy Marketplaces: Digital platforms for simplified contracting.
- ESG Analytics: Granular data for corporate decarbonization strategies.
In short, 2025 was the year of regulation; 2026 will be the year of implementation and innovation.
