摘要

Since mid-1990, energy trade in Brazil went through deep changes. Initially, in 1996, changes weremainly motivated by the limited investment capacity of the state facing the needs of demand as well asthe privatization. So a competitive environment was introduced. Later, from 2004, some adjustmentsoccurred. Emphasis was given to the aspects of low tariffs, system security and supply expansion.The current regulation divides the Brazilian Power Market in two environments:1. ACR (Regulated Environment), a segment of the market where the purchase and sale of electricitybetween purchasing agents and selling agents (the distributors) is carried out, for service to finalconsumers (captive consumers) of distribution utilities;2. ACL (Free Environment), a market segment where the procurement of energy is freely negotiatedand is intended for service to free or special consumers.The ACR represents 75% of the Brazilian Market and the energy’s trade takes form solely as auctionswhich are organized and conducted by the Brazilian Government. Following the MME - Ministry ofMines and Energy, the conceding power, the ANEEL, the regulatory body, and the CCEE, the marketoperator, are modeling and organizing several auctions for the sale of electricity from existing sourcesand those to be built.In the ACL negotiation is bilateral and free between the parties. However, state-owned companiesmust commercialize electricity in order to ensure publicity, transparency and equal access to allstakeholders. Thus, these companies trade their energy through auctions, either in ACR or in ACL.Many auctions have been used in procuring electricity in the Brazilian market. In the auctions ofexisting energy the competition takes place in the market while in auctions of new generation projectsthe competition occurs for the market. Various forms and methods of auctions were used.Therefore, this work seeks to identify the main characteristics of the electricity auctions in theBrazilian power market, where theoretical aspects and possible alternatives for formatting arehighlighted. The results of the auctions occurred in Brazil are shown.

ACR（管制环境），即购销电力的市场部分 在采购代理商和销售代理商（分销商）之间进行，以提供最终服务 配电公司的消费者（专属消费者）; 2. ACL（自由环境），自由协商能源采购的市场领域 旨在为免费或特殊消费者提供服务。 ACR代表巴西市场的75％，而能源的贸易形式仅仅是拍卖而已 这些活动是由巴西政府组织和实施的。继MME之后- 矿产和能源，让步权，ANEEL，监管机构和CCEE，市场 运营商正在建模和组织几次拍卖，以出售现有资源中的电力 和那些要建造的。 在ACL中，谈判是双方之间的双边和自由谈判。但是，国有企业 必须将电力商业化，以确保宣传，透明和平等获得所有人 利益相关者。因此，这些公司通过ACR或ACL中的拍卖来交易能量。 在巴西市场上，许多拍卖活动已用于购电。在拍卖中 现有能源的竞争是在市场竞争中进行的，而在新一代项目的拍卖中 市场竞争。使用了各种形式和拍卖方法。 因此，这项工作试图确定电力拍卖的主要特征。 巴西的电力市场，理论方面和可能的格式替代方法都在这里 突出显示。显示了在巴西发生的拍卖结果。
