Net Metering in Brazil

Introduction

Currently the solar energy plays just a marginal role in Brazil’s energy supply. The almost endless solar resources has no market for small scale solar systems.However,the new Net Metering regulation 482, introduced by the Brazilian electricity sector regulatory body 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.

The cooperation of the Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) GmbH, acting on behalf of the German Federal Ministry for Economic Cooperation and Development (BMZ), with Brazil in the field of sustainable development is helping the Brazilian partners to develop new ways of tapping the enormous potential for using renewable energies and to promote energy efficiency, particularly in industry and buildings. GIZ provides advice on strategy development, support for developing management and cooperation structures, and technical expertise.

In 2012, the first Brazilian photovoltaics pilot project, the solar-powered stadium Pituaçu in Bahia state was inaugurated. This successful venture, implemented by the local energy provider COELBA and supported by Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) GmbH, 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.

This paper assesses the profitability of decentralised electricity generation within the Brazilian housing and commercial sectors using the example of photovoltaics in the context of the introduction of the Net Metering system. The analysis is limited to the low-voltage level, since it has by far the highest retail tariffs.

Preparation

• Brazilian Atlas of Solar Energy (2006)

The Brazilian Solar Energy Atlas includes maps and digital data of various solar radiation components as well as detailed infrastructure and socio-economic parameters. The resulting database is compatible with the Geographical Information Systems (GIS) and therefore may be easily employed in feasibility studies during renewable energy project development. After analysing the temporal and spatial variations and trends of solar energy resources, the atlas presents some solar energy scenarios for Brazil.

• Survey of the Electricity Market in Brazil focusing on Distributed Generation (2011)
• Estudo sobre o Mercado de Energia Elétrica no Brasil focando na Geração Distribuída (2011)

In Brazil, electricity must be traded in one of two environments of the market, the Regulated Contracting Environment – ACR and the Free Contracting Environment – ACL. This report describes the main characteristics of the two market environments, with the purpose of assessing the possibility of implementing distributed power generation in Brazil through photovoltaic projects. It also indicates the states that are already offering tariff parity. Another conclusion is that in the Brazilian scenario, the metering system in the net-metering mode is more feasible than the feed-in tariff model.

• Challenges and Opportunities of the integration of new consumers and decentralized power plants (2009)

The main objective of this study is to inform about the current regulations, standards, as well as control and measurement methods of reactive power and power factor applied in Europe. Furthermore, the study describes interrelated challenges of and opportunities for the integration of new consumer groups and decentralized renewable energy based power generation.

This article gives an overview on the renewable energy support policies - Feed-in tariffs and Net Metering - analyzing their legal framework in Germany. It subsequently develops perspectives for Net Metering in Brazil. Further attention is paid on the impact of decentralized generation on load curves and distribution infrastructure.

• International Procedures for the Connection of Small Distributed Generators to the Power Grid (2011)

To help ANEEL developing the legal procedures for decentralized distributed generation, this study addresses the legislation in Germany and Italy as reference countries with sharp increase of decentralized power generation plants up to 1 MW, in particular from renewable energies, in the recent years. 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)

The purpose of this document is to present and compare international technical standards for interconnecting small distributed generation units to the public grid in different European countries (Germany, Italy and Spain) and the United States of America. It also presents recommendations for a simplified connection procedure in coherence with Net Metering.

• Regulatory Framework for the Interconnection of the Costumer in Brazil - Generators and its Barriers (2011)

The report explains the former status quo of the proceedings in costumer-generation projects before the introduction of Net Metering in Brazil. It aims to identify interconnection barriers resulting from regulatory obstacles in Brazil. Therefore, it shows the development of PV in Brazil, an overview of the regulatory framework, rules and proceedings for interconnection of distributed generation at that time and gives recommendations how to interconnect despite the interconnection barriers and advice on 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.

• Pesquisa relacionada aos consumidores B3 no Brasil (2012)

This study shows the methodology utilized to calculate the yearly average electricity consume of the Brazilian consumer group B3 (commercial and small industry). To get to know the behaviour of consumption groups is indeed important for the process of tariff revision or the calculation of marginal costs calculation and the basis tariff related to distributed generation.

• Metodologia de mapeamento da área potencial de telhados residenciais para PV no Brasil (2012)

To amplify the use of small scale energy generators, this study develops a methodology to estimate and map the potential of residential housing rooftops for electricity and heat generation produced by photovoltaic panels and solar collectors. The methodology regards aspects of the country-specific sun irradiation, total rooftop area and areas improper for use.
