Brazil’s power regulator Aneel has approved the A-3 and A-4 energy auctions, scheduled to be held June 25. The start dates of power supply from the undertakings contracted in the A-3 and A-4 tenders are Jan. 1, 2024, and Jan. 1, 2025, respectively.
According to BNamericas, Aneel also included a new lot in the power transmission auction to be carried out in December.
Federal energy research company EPE has registered 1,841 projects for the auctions, which represent combined generation potential of 66,862 MW.
For wind and PV solar projects, which account for 64,519 MW of the total power generation registered, the supply term will be 20 years. In the case of thermoelectric biomass projects, with 1,358 MW registered, the contracts are for 20-year supply. Hydroelectric projects, with 985 MW of the registered generating capacity, will be contracted for a 30-year period.
For projects already holding a concession, the reference prices will be BRL245/MWh for mini hydro plants (under 5 MW) and small hydroelectric plants (5 MW to 30 MW) and BRL170/MWh for other hydroelectric plants (over 30 MW).
In the case of projects without authorization from Aneel, the initial contract prices will be BRL292/MWh (US$55.50/MWh) for hydroelectric sources, BRL198/MWh for wind and solar sources and BRL292/MWh for thermoelectric biomass source.
Some 67% of the registered projects are located in four states in the northeast region, which account for 69% of the power registered with EPE for the two auctions: Bahia, with 597 projects (20,727 MW), Rio Grande do Norte, with 259 projects (9,208 MW), Ceará, with 195 projects (8,768 MW) and Piauí, with 189 projects (7,448 MW).
Only 54 projects are registered to participate exclusively in the A-3 auction and 340 to participate solely in the A-4 tender. The remaining 1,447 projects will be able to participate first in the A-3 auction and then negotiate the remaining power in the A-4 auction.
The board also approved the inclusion of a power transmission lot in Amapá state to be offered in the second transmission auction, which will be held Dec. 17. The agency will open a public call on Thursday for a detailed study of the lot.
It calls for the construction of the 10-km Macapá-Macapá III transmission line and the Macapá III substation, with 2×150-MVA transformation capacity. The project is designed to offer a structural solution for electricity transmission in the Macapá region to avoid new blackouts. Construction is scheduled to take up to 42 months and will require BRL125 million in investments.
With a completion period of 30 months to 60 months, the lines will be built in Amapá, Bahia, Minas Gerais, Paraná and São Paulo states.
