Net Metering in Brazil

Introduction

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 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) are promoting and disseminating the use of solar PV in Brazil.

Fact- & Infosheets

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.

Solar pilot project Megawatt Solar - Solarpilotprojekt Megawatt Solar (2014)

In May 2014, another solar energy pilot project supported by the GIZ entered in operation: the 1 MWp photovoltaic system on the rooftop of the energy provider Eletrobras Eletrosul’s head office in Florianópolis. The project’s aim is to raise public awareness for Net Metering and Photovoltaics and to train relevant local actors in the field of decentralized power generation. GIZ thus offered technical expertise on the installation of the system as well as marketing of the produced electricity. An effective measure therefore was the commercialization of the electricity through the Solar Label, an initiative introduced by IDEAL Institute.

Strategic PV research and development project in Brazil - Strategisches Forschungs- und Entwicklungsprojekt Photovoltaik in Brasilien (2014)
Primeiro programa de incentivo à energia fotovoltaica (2014)
To amplify and diversify the application of financial resources of the ANEEL’s Research & Development Program for renewable energy projects, ANEEL created the Strategical R&D Photovoltaic Project. Since 2011,GIZ support ANEEL in developing a tender that encouraged energy companies to apply their R&D resources on commercial solar generation plants up to 3 MWp. Thus this measure could significantly improve spending on research and development of renewable energies in Brazil. 18 Photovoltaic projects has since been approved by ANEEL, some of them, for example the world cup solar stadiums Recife, are already realized involving huge private investment. Through the Strategical R&D Photovoltaic Project, 165.000 Euro of German spending led to 100 Mio. Euro Brazilian investment.

Maracanã Solar - Solar electricity for the football world cup 2014 - Maracanã Solar - Solarstrom für die WM 2014 (2014)
The worldwide famous Maracanã-Stadium in Rio de Janeiro was equipped with solar panels within the efforts of linking the football world cup 2014 to the promotion of solar energy. Therefore, the GIZ supported LightESCO, an Energy Service Company owned by local energy provider Light, during the conception of a PV power plant on the rooftop of Maracanã. With 390 kWp, it is the most powerful PV system in Rio de Janeiro state, and a main driver to leverage Net Metering in Brazil. The success of this project motivated Light to kickstart further PV projects in the region, also with German private sector engagement.

Solar Energy for Fernando de Noronha island - Erneuerbare Energien und Energieeffizienz - Solarenergie für Fernando de Noronha (2015)
The Brazilian island Fernando de Noronha is a nature paradise and conservancy unit – good reasons to seek for clean energy solutions in order to substitute the presently prevalent thermo-electric power generation with biodiesel generators. GIZ therefore supported the first PV pilot project on Fernando de Noronha, incentivized by the Brazilian Energy Efficiency Program (PEE) and executed by the energy provider CELPE with an investment sum of five Mio. BRL (aprox. 1.7 Mio. EUR). The PV power plant Fernando de Noronha I, which has an installed capacity of 400 kWp, can already cover four percent of the islands´ electricity demand; its successful implementation led to the construction of a second PV power plant on the sunny island.

It gives an overview of the relevant energy law provisions and, in this context, existing contracts between energy operators and grid operators for the interconnection of small distributed power generation plants.

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.
