Recent Debates About Solar Energy Subscription Have Raised Concerns About Possible Regulatory Changes That Could Impact the Sector. Technical Note 101 of 2023 from ANEEL Invites the Sector to Discuss the Need for Specific Regulations for This Business Model.
Solar energy subscriptions, offered by owners of solar farms, are under regulatory scrutiny. The practice, which offers discounts on consumers’ energy bills, is being analyzed by ANEEL to determine if it requires stricter regulation.
Entrepreneurs have invested in solar farms in the captive market, profiting from the indirect sale of energy. These investors establish photovoltaic solar farms and link them to cooperatives, allowing the membership of an unlimited number of members.
Mechanics of Solar Farms
Cooperative members rent a portion of the solar farm and receive energy credits, paying a monthly fee that is, in practice, a payment for the use of photovoltaic equipment. This strategy offers a discount of 5 to 15% on consumers’ energy bills in exchange for the monthly fee.

Solar energy can increase property value by up to 10% and become a selling point.

Illiterate or semi-literate grandmothers were trained to repair solar systems, open rural workshops, and light up homes that still depended on kerosene.
ANEEL seeks to understand if the solar energy subscription is being used for profit within the distributed generation model, which could be contrary to current guidelines that prohibit the sale of energy in the captive environment.
There is concern that some businesses are using solar energy subscriptions in a way that circumvents energy sales regulations, characterizing their contracts more as energy sales than as equipment rentals.
Future of Solar Energy Subscription
Although the future of this practice remains uncertain, ANEEL is gathering inputs to make an informed decision. Companies operating under this model must ensure that their practices are legally compliant, avoiding characterization as direct energy sales.
The discussion about solar energy subscriptions is open, with significant implications for the solar energy sector. ANEEL’s final decision will determine the future of this business model, which currently enjoys popularity among consumers and investors. The public consultation is open until January 31, 2024, and the sector’s participation is crucial for defining the way forward.
