TR is a technology company specialized in electricity tariffs and SaaS (Software as a Service) development. Its main software platform is a tool for forecasting the Brazilian electricity tariffs. SETE (linkado) reproduces the electricity tariff calculating methodology according to the procedures defined by the Brazilian regulator Aneel. The professional experience of the TR team and its tireless pursuit for the power market knowledge enable any legal or regulatory change to be promptly integrated to its platform, allowing the measurement of any sort of tariff impact. This is, therefore, a market intelligence tool needful to all market agents, from consumers to generator, utilities and electricity traders, or anyone interested in understanding and following the evolution of the Brazilian electricity tariffs. Another item of TR`s portfolio is a tool developed for forecasting the annual revenue of the power plants whose long term concessions have been ended or will end in the next thirty years. The platform allows viability analysis for new investments in reinforcement and in new assets. Focusing the residential market and the monitoring of small distributed generation, TR has developed an unpaid platform that allows its users to follow their residential electricity consumption and the evolution of their bill, and enabling the user to synchronize its solar generator system in real time. When synchronizing his/her residential photovoltaic system to Oráculuz (www.oraculuz.com.br), the user can follow his/her daily electricity generation and also the consumption, making it possible for he/she to know precisely what will the compensation be, in BRL, and accordingly to the actual tariff of each Brazilian electricity utility.
