The utilisation of solar resources has become of utmost importance for the transition of the global, carbon intensive economy. In New Zealand the uptake of solar energy has increased substantially, but the relative contribution to the overall energy mix is still small. Previous research efforts on the solar resource across the country are revisited with improved satellite-modelled data from Solargis to derive a solar atlas for the country. A comparison is made with NIWA data, which shows that the modelled data are at an adequate level of accuracy and improves our understanding of the solar resource at an appropriate spatial and temporal resolution. The solar atlas makes available a commercial satellite data source and informs further investigations into how solar can, and will, play a more meaningful role in our transition to a low carbon future.

Section: Risks With Contractsmentioning

“…While the use of energy sources with low marginal production costs decreases the prices paid for energy in the market [9,13], its lack of security of supply due to dependence on climatic conditions causes high volatility in final prices [70]. That is, when the system lacks operational reserve, the consumer tends to pay high prices for energy in the MCP [46,49,[56][57][58]. The authors [54] point out that, while in the regulated environment the price paid for energy remains, in the free environment it varies according to the market.…”

“…Because they are sources that show variability and uncertainty, as they have intermittent energy generation and are subject to prolonged periods of resource scarcity, the Supply Risk factor addresses the risks in the supply of electricity from renewable energy sources. In periods of scarcity, the prices paid for electricity tend to increase [57,58].…”

“…In Brazil, for example, the electrical matrix is mainly composed of hydroelectric plants, with 69.7% representing them [78]. This source is subject to unpredictable water flows since the calculation is attributed to stored water, that is, in periods of scarcity the prices paid for energy tend to increase [57,58]. In systems with a lack of operational reserve, the values attributed to scarcity are offset in the cost of energy [46].…”

Determining Factors and Scenarios of Influence on Consumer Migration from the Regulated Market to the Deregulated Electricity Market

et al. 2020

Due to the constant evolution of the electricity markets around the world, new possibilities for contracting electricity are emerging. In Brazil, there are two models available to the consumer: the regulated contracting environment and the free contracting environment. Because of these possibilities for contracting electricity, it is important that consumers know how to migrate from the regulated to the free environment when it is an advantage. This study was conducted following the premises of three techniques: systematic literature review, gray literature review, and expert panel. The following question was asked: What are the determining factors to be considered by the consumer at the moment decision to migrate from the regulated electricity market to the free market? In total, 7 factors were identified and discussed in the literature review. The experts who participated in the study pointed out 3 influential scenarios in this decision making to migrate. The main contribution of this study is to provide the consumer with subsidies for decision making, given the determining factors to be taken into account when deciding on migration or not. In addition, the study contributed to the sector through a comprehensive discussion about the scenarios faced by consumers and how they can influence decision making.
