São Paulo, Brazil — (METERING.COM) — October 26, 2009 – Brazil’s energy regulator Aneel last week revealed its tentative plans for nationwide rollout of smart metering in Brazil.
Under the plans, which were announced by Aneel electricity public services regulator Hugo Lamin, on the first day of the Metering, Billing/CRM Latin America conference and exhibition in São Paulo, nationwide rollout of approximately 63 million smart meters would start in early 2011 and should be completed within a 10-year period.
The meters would be required to measure voltage, current, active and reactive energy consumed, active and reactive demand, power factor and frequency. Minimum functionalities would include registering the frequency and duration of interruptions, registering the duration of voltage transgressions, the ability to offer both post- and prepayment, and remote actuation and remote reading facilities.
The aim of the regulator is to provide minimum requirements for smart meters and guidelines for their replacement, said Lamin, adding that the proposals were still under discussion and still to be finalized.
The smart metering regulatory process was launched with an international seminar in October 2008, and subsequently has undergone a public consultation (see Public consultation on electronic metering launched in Brazil). Lanin said there was a lack of consensus among the 34 respondents to the consultation and therefore there was a need for further clarification.
Lamin also said that an open communication protocol should be specified, and that compulsory customer information should include both the availability and visualization of consumption information, the value and identification of the tariff for post-payment and for prepayment the monetary value of the consumption to date and amount remaining.
Lamin also noted issues that are still to be investigated, including the regulatory (depreciation) lifetime of smart meters and the need for penalties by utilities for not achieving the rollout targets. In addition a systematic analysis is needed on the costs and their potential impact on the tariff, provisionally estimated at a maximum of 2 percent per year.
