  • Developing Brazil's Market for Distributed Solar Generation
    Developing Brazil’s Market for Distributed Solar Generation Juliano Assunção Climate Policy Initiative (CPI) & Núcleo de Avaliação de Políticas Climáticas da PUC-Rio (NAPC/PUC-Rio) | Department of Economics, PUC-Rio [email protected] Amanda Schutze Climate Policy Initiative (CPI) & Núcleo de Avaliação de Políticas Climáticas da PUC-Rio (NAPC/PUC-Rio) [email protected] September 2017 Abstract We show the availability of solar resources is a poor predictor of the penetration of distributed photovoltaic (PV) generation in Brazil. Analyzing data from 5,563 municipalities in Brazil, we show that demand-side factors such as population, GDP, and electricity tariffs prevail as key determinants of PV undertake. Solar radiation only appears as positively correlated with PV adoption when comparing municipalities within the same influence area of electricity providers. Public policies should target frictions on the demand for electricity to promote PV. In addition, estimates of the potential of renewable sources to mitigate climate change are upward biased if demand-side factors are not taken into account. Keywords distributed generation, solar photovoltaic, radiation Jel codes Q01, Q40, Q41 Acknowledgments Isabela Salgado and Maria Mittelbach provided excellent research assistance. 1. Introduction Renewable technologies are seen as a key instrument in combatting greenhouse gas emissions and climate change, and the availability of renewable natural resources is regarded as the main requirement for a nation’s ability to reduce climate risk (IPCC, 2014). However, the development of the renewable energy sector occurs not only through determinants of supply, i.e., the availability of natural resources, but also through aspects of demand.

Clamp or clamps are placed 3 PHASE around the mains cable and voltage SENSOR detectors are magnetically located on the appropriate fuses. The transmitter is small enough to fit unobtrusively inside most fuseboxes. The transmitter connects securely your local WiFi network or via GSM and immediately starts sending live data to our servers. You can be connected in 5 minutes. Data analysis STORAGE Total consumption and cost data is available immediately; live, daily, or monthly. Our machine learning algorithm takes about a week before it begins to identify appliances by their electrical signatures. We use artificial intelligence to ANALYSIS model consumer behaviour and this allows us to deliver periodic detailled breakdowns of cost and consumption.

  • Guide To: 17Th Edition Consumer Units Introduction
    Guide to: 17th Edition Consumer Units Introduction For well over one hundred years the Wiring Regulations have provided the rules which must be followed to make sure that electrical installations are safe. The introduction of the 17th Edition of the Wiring Regulations and subsequent amendments have had major implications for all Electrical Contractors, Designers and Consultants. Several regulations have an impact upon circuit design, consumer unit layout and even the construction of the consumer unit itself. This guide will help you understand the new Wiring Regulations and current Building Regulations, providing the necessary facts to construct compliant installations including Consumer Units. If after reading this guide you would like to find out further information regarding the new regulations Hager offer tailored training courses.
