Energy powers the country, and every decision in the electric power sector involves technical rules, complex contracts and close scrutiny by regulatory authorities. This is where electric power law becomes critical: a poorly drafted clause or a missed regulatory deadline can jeopardize an entire project. TAGD Advogados assists companies across every link in this chain—generation, transmission, trading and distribution—with particular emphasis on energy trading and renewable sources. Our work begins with transaction and project structuring, continues through contract negotiations and extends into the operational phase, always with careful attention to dealings with ANEEL, MME, EPE, ONS and CCEE. We advise generators, energy traders, free-market consumers and investors seeking predictability in a rapidly changing market. We also assist companies migrating to the Free Contracting Environment and pursuing distributed generation opportunities. Rather than merely resolving isolated issues, we help clients identify risks before they materialize. If your company operates or intends to operate in the electric power sector, now is the time to rely on counsel who understands the industry.










Electric power law comprises the rules, contracts and practices governing the generation, transmission, trading, distribution and consumption of electricity in Brazil. It covers the entire chain, from generation at hydroelectric, thermal, solar and wind power plants to delivery to end consumers through transmission and distribution networks. Because electricity is an essential commodity supported by large-scale infrastructure, the sector is heavily regulated, and every market participant must understand its obligations in order to operate securely.
Brazil’s electric power sector is coordinated by several entities, each with a defined role. ANEEL regulates and supervises the market; MME formulates public policy; EPE conducts planning studies; and ONS operates the interconnected system. Energy trading takes place through CCEE, which administers transactions in the Free Contracting Environment (ACL) and the Regulated Contracting Environment (ACR). Matters such as energy auctions, migration of free-market consumers and distributed generation—currently governed by Law No. 14.300/2022—require careful analysis of the applicable rules and ongoing regulatory updates.
TAGD Advogados assists companies across all these fronts, turning regulatory complexity into sound decisions and business opportunities. We help generators, energy traders, distributors and consumers structure projects, negotiate contracts and engage with sector authorities, always with a focus on energy trading and renewable sources. If your company seeks to grow in the electric power sector with predictability and legal certainty, speak with a TAGD specialist to learn how we can support every stage of your operations.
Q: What does an electric power lawyer do?
A: Electric power lawyers advise companies and investors on sector rules, including contracts, licenses, regulatory matters and disputes. In practice, they help generators, energy traders and consumers operate securely and capitalize on market opportunities. They also monitor regulatory changes involving authorities and entities such as ANEEL and CCEE.
Q: What is the difference between the free and captive energy markets?
A: In the captive market (Regulated Contracting Environment), consumers purchase electricity from the local distributor at regulated rates. In the free market (Free Contracting Environment), consumers negotiate price, term and supplier directly, which often generates savings. Migration requires technical and legal analysis to determine whether it is advantageous in the specific circumstances.
Q: What did Law No. 14.300/2022 change for distributed generation?
A: Law No. 14.300/2022 established the legal framework for distributed microgeneration and minigeneration, providing greater certainty for those who generate their own electricity, including through solar systems. It set transitional rules for grid-use charges and deadlines for parties with existing or pending connection requests. Understanding these deadlines is essential when planning investments in renewable energy.
Q: Which companies need legal advice in the electric power sector?
A: Generators, energy traders, distributors, free-market consumers and energy investors all benefit from specialized legal advice. This applies both to large generation projects and to companies seeking to migrate to the free market or install distributed generation systems. Legal support reduces regulatory risks and helps prevent contractual losses.
Q: What is a power purchase agreement (PPA)?
A: A PPA formalizes the purchase and sale of electricity between a generator or energy trader and a consumer, setting out price, term, volume and security arrangements. It is the foundation of free-market transactions and must be carefully drafted to allocate risk appropriately between the parties.
Q: How does legal advice assist with migration to the free energy market?
A: Counsel analyzes regulatory requirements, contracts, operational risks and obligations before CCEE, helping the company migrate securely and with economic predictability.
Q: Which legal issues are critical in solar and wind generation projects?
A: It is essential to review authorizations, grid connection, licensing, EPC contracts, leases and power purchase agreements to prevent delays, penalties and contractual imbalances.
Q: When should a company engage an electric power lawyer?
A: Whenever the company participates in a generation or energy-trading project, the free market, distributed generation or regulatory negotiations, because preventive legal advice reduces risk and protects the investment.
