“…To evaluate the proposed models, we took a typical business day in June 2015 for one Brazilian distribution company. ANEEL provided the network and load data, 1 and Table 1 shows the feeder data. Each load was formulated to be 50% constant impedance and 50% constant power, with a power factor of 0.92 for LV loads, and 0.93 for medium-voltage (MV) loads.…”

“…In contrast to other countries where feed-in tariffs have been applied, Brazil introduced net-metering in 2012, through Resolution 482 of the Brazilian National Electrical Energy Agency (ANEEL) [1]. This resolution has influenced the Brazilian energy market, particularly the solar energy segment, which was effectively non-existent before 2012, but which had grown to 5GW installed capacity by 2020 [2].…”

The regulation of Distributed Energy Resources (DERs) has cast doubt on the sustainability of utility infrastructure charging models. The development of feed-in tariffs, net-metering, and network charge rebates for distributed generation (DG) has been questioned because of the cross-subsidies that result between passive consumers and DG investors. Besides DG investors, other new entrants, such as owners of energy storage resources and electrical vehicles, are creating challenges for the regulation of distribution service pricing as a whole. This paper proposes a new approach to dealing with the fixed cost element of service pricing, that enhances economic signaling in the distribution network. We isolate and address the issue from a distribution network point of view, by excluding from our model the random variables associated with the complexity of social, environmental and other externalities. The solution developed is particularly relevant at a time when distribution networks, historically dominated by passive users, struggle to adapt to a dramatic increase in the number of users who are active agents. It considers the principles governing tariff design from the perspective of simplicity, economic signaling, and revenue reconciliation. Results are presented of simulations performed with different arrangements of alternative energy generators and energy storage devices, using an actual feeder from a distribution company in Brazil. An analysis of these results is provided that suggests a combination of locational and time-of-use rates can provide effective economic signals to these new types of system user.

“…Regulatory frameworks need to evolve to incite DSOs to implement smart and flexible solutions at local level as cost efficiency measures, thus moving beyond a CAPEX-based to a TOTEX-based (total expenditure) framework, with incentives to improve quality of service and innovation. This vision has been set out by a number of stakeholders, from academics [22][127] [129] and regulators [130][131] [132], to DSOs themselves [5][39]. An example of this shift is the UK's performance-based network regulatory framework RIIO (Rev-enue=Incentives+Innovation+Outputs) that incites DSOs to create value for end-customers instead of just investing in new assets [133].…”

Sustainability transitions have caused major changes in the energy sector which has drove electricity companies to seek new processes, products, and services. Within this context, business models are conceptual tools that express business logic. Furthermore, they consist of a value proposition in services that at the same time generates benefits for consumers of energy and revenue for these companies. This work aims to show one of the innovations in the electricity company in Brazil -CPFL Energia, which is the third biggest Brazilian electricity utility company, as well as its presentation through the development of three Canvas business models. The methodology was a literature review on the proposed theme through a bibliometric analysis. The single case methodology was applied to target: residential and industrial consumers with hour-seasonal tariffs. The study concluded that for it to become economically viable, electricity regulatory evolution is necessary which encourages the use of energy storage systems. Furthermore, industrial consumers still have the benefit of reducing the energy demand contract.
