Net Metering in Brazil

From energypedia


Currently, solar energy plays just a marginal role in Brazil’s energy supply. The almost endless solar resources have no market for small scale solar systems. However, the new Net Metering regulation 482/2012, introduced by the Brazilian electricity sector regulatory body (Agência Nacional de Energia Elétrica, ANEEL), has finally opened the doors to tap a vast potential for decentralized small scale electricity generation up to 1 MW. It is a big step for Brazil´s renewable energy sector and great opportunities for German technologies in the Brazilian market. Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) GmbH[1] supported ANEEL to develop and implement the Net Metering regulation. Further to this, the IDEAL Institute(Instituto para o Desenvolvimento de energias alternativas na América Latina)[2] and the Brazilian Association for Solar Photovoltaica Energy (ABSOLAR - Associação Brasileira de Energia Solar Fotovoltaica[3]) are promoting and disseminating the use of solar PV in Brazil.


From the first solar-powered stadium in Latin America to PV Business for everybody (2013)

Pituacu Solar Stadium - Salvador da Bahia

Vom ersten Solarstadion Lateinamerikas zum brasilianischen Net Metering (2013)
In 2012, the first Brazilian photovoltaics pilot project, the solar-powered stadium Pituaçu in Bahia state was inaugurated. It was implemented by the local energy provider COELBA and supported by GIZ. This successful venture established further progress to increase the share of photovoltaic-generated electricity in the Brazilian energy system. Consequently, ANEEL introduced a Net Metering system within a new regulation for decentralized small scale electricity generators up to 1 MW.

Pituaçu Solar - The first solar stadium in Brazil - Pituaçu Solar - Das erste Solarstadion Brasiliens (2012)
In the course of football world cup 2014, the idea to utilise public´s attention in Brazil to introduce catchpenny photovoltaic projects through football was born. Shortly after, the Brazilian energy supplier COELBA supported by GIZ introduced a pilot project to build the first Brazilian solar stadium Pituaçu, with a capacity of 400 kWp. Financed by the Brazilian Energy Efficiency Program (PEE), the German-Brazilian EPC Gehrlicher Ecoluz Solar realized the installation of the system. This project led to investments of 2 Mil. Euro from the Brazilian private sector, applying 60.000 Euro of German public tax resources for the project.

Unbureaucratic Net Metering for decentralized electricity generation in Brazil - Unbürokratisches Net Metering für dezentrale Stromerzeugung in Brasilien (2013)
Reduce administrative barriers to make grid connection of decentralized renewable energy generators viable – that was one aim of ANEEL and GIZ within the German Cooperation for Sustainable Development to achieve sustainable energy use in Brazil. Within this fruitful partnership, ANEEL used its regulatory competence to reduce bureaucratization of grid connection, enabling small electricity producers by resolution 482/2012. GIZ advised ANEEL on technical and administrative aspects of the introduction of a Net Metering system and organized trainings and technical visits.

Standards for the Connection of Small Distributed Generators to the Power Grid (2011)
Legal-administrative barriers for the connection of small distributed generators led in the past to negative impacts on the implementation of decentralized generation in terms of longer project durations, higher costs, longer waiting times and more demanding labor requirements. The comparison and assessment of different international technical standards for interconnecting of small distributed generation units to the public grid in the European countries (Germany, Italy and Spain) and the United States of America, thus, allows to derive recommendations for a simplified connection procedure in coherence with Net Metering in Brazil.

Regulatory Framework for the Interconnection of Costumer-Generators and its Barriers (2011)
The former status quo of the proceedings in costumer-generation projects before the introduction of Net Metering in Brazil did not allow the injection of electricity from distributed generation in the grid. Hence, the missing regulatory incorporation of distributed generation respective costumer generation is the fundamental barrier for its diffusion. To achieve the simplification of the connection procedure for costumer-generation, interconnection barriers resulting from regulatory obstacles in Brazil are identified as well as an overview to the development of PV in Brazil and the regulatory framework, rules and proceedings for interconnection of distributed generation is given.The aim is to enable interconnect despite the interconnection barriers and develop attempts on the introduction of incentive schemes within the legal framework.

Consequences on Grid Operation by Decentralized Renewable Power Generators (2011)

In Germany, lately some developments with respect to renewable power generation and its connection to the different voltage levels occurred. Due to the enormous increase of such installations and the fact that renewable power generation units so far have been considered more or less as “negative loads”, but without consideration of their capabilities to act in the same way as conventional power plants, certain problems arose. This report identifies these problems and discusses the policy measures to address them.

Business Model for the Brazilian Net Metering

Stakeholders chart

Assisted by accountants and lawyers, GIZ Brazil developed a Business Model for Brazilian Net Metering based on private investments. The business model is designed for renewable energy entrepreneurs and consists in attracting investors to purchase equipments for distributed power generation in order to rent them to third parties.

Renewable Energy Cooperatives

Brazil has a strong tradition of cooperatives, with currently more than 6,600 cooperatives and more than 13 million associates. This provides a great opportunity for distributed renewable energy generation. Recently, the national electricity regulator ANEEL introduced a norm that allows the net-metering scheme to be used not only by households but also by cooperatives and condominiums.

The BMZ funded projected “Energy Systems of the Future”, implemented by GIZ in cooperation with the Brazilian Ministry of Mines and Energy (MME), has supported the development of a booklet that provides guidance on that new business model for renewable energy generation. The booklet explains the basic aspects of a renewable energy cooperative and provides orientation on the legal structure and financial viability.

The booklet was officially launched by the Brazilian Cooperatives Organization (OCB) on May 2018 in Brazil with the participation of more than 50 regional OCB representatives who will further disseminate the information along with support activities to foster capacity building and implement first pilots.

The German experience with the business model of renewable energy cooperatives has strongly been utilized within a close collaboration with the German Cooperative and Raiffeisen Confederation (Deutscher Genossenschafts- und Raiffeisenverband, DGRV).

The booklet is available at OCB Webpage.(Only in Portuguese)

It was part of the scope of action as well the development of individual and institutional capacities. So, almost 800 people participated in 12 regional workshops about this business model and photovoltaic solar energy, of which about 10% were members of the technical staff of OCB´s regional units (80). Also, the new business model was presented at 18 renewable energy events in different regions of Brazil along 2017 and 2018.

An online simulator was developed by Ideal Institute and Photovoltaic Group of the Federal University of Santa Catarina (UFSC) based on the parameters designed in the guide and integrates the main knowledge platform on photovoltaic energy in Brazil - Programa América do Sol.
