Time based credits and Law 14,300 add two variables to distributed generation contracts

Distributed generation has always offset in kilowatt hours. An article by Marina Meyer Falcão in Canal Solar, of 11/10/2026, analyzes ANEEL's Joint Technical Note No. 14/2026, which makes time of use pricing the default in low voltage and makes each credit worth the value of the time slot in which it was generated. Systems connected from 90 days after the rule enter with no option to leave.

Law No. 14,300/2022 had already begun to split the grid bill. Under article 27, units outside the rule of article 26 pay a growing share of the components that remunerate distribution assets, depreciation and operation and maintenance: 60% in 2026, 75% in 2027 and 90% in 2028.

The two effects add up. Plant leasing, consortia and cooperatives now carry two variables in the same long term contract: the share of grid cost that falls on the unit and the time at which the credit is used.

The proposal still depends on ANEEL's Board. Until then, each unit can be simulated under time of use pricing to see who absorbs the difference in each contract. A well measured project still stands. A contract without an adjustment clause is exposed.
