Brazil's power sector regulator Aneel approved on Tuesday a new set of rules for distributed generation (DG) systems, including allowing projects of up to 5 MW.
From March 1, 2016, when the rules start to apply, any renewable source, in addition to the qualified cogeneration, can be used in DG systems.
Capacities of up to 75 kW will qualify for microgeneration scemes while minigeneration will range from 75 kW to 5 MW. Hydropower sources will be capped to a maximum capacity of 3 MW.
Consumers will be able to gain credits for the surplus output and use these to lower the electrical bill for the following months or the cost of other DG systems as long as connected to the same distributor company. This use of the credits has been named as "remote self-consumption." DG systems are also allowed to be installed in condominiums and in consortium.
Aneel will closely monitor the implementation of the new rules and expects Brazil to have about 1.2 million DG systems with a total capacity of 4.5 GW by 2024.
