  • Genneia won 421 MW across seven projects, about 60% of the round, including Cruz Alta I (120 MW) and Bragado I-II (100 MW); DQD Energy took eight sites, 360 Energy three, and Aluar and Intermepro one each.
  • The auction was heavily oversubscribed, drawing 235 offers from 37 firms totaling 8,338 MW, nearly twelve times the 700 MW target.
  • The first phase is expected to drive an estimated $700 million in new investment, with Genneia's winning floor around US$7,397 per MW-month.
  • State grid operator CAMMESA has been instructed to notify winners and sign storage agreements.

Argentina Awards 700 MW BESS, Genneia Wins 60% of AlmaSADI Round

Argentina's grid just took a big step into battery storage. On July 7 the country's Secretariat of Energy issued Resolution 155/2026, formally awarding 700.5 MW of battery energy storage systems (BESS) across 20 projects under the AlmaSADI tender, spread among five developers and instructing state grid operator CAMMESA to notify winners and sign storage agreements.

Genneia sweeps 60% of the round

Wind and solar heavyweight Genneia was the biggest winner, capturing 421 MW across seven projects — roughly 60% of the awarded capacity. Its portfolio includes Bragado I-II (100 MW), Cruz Alta I (120 MW), Crespo (50 MW), Chascomús (45 MW), Mar de Ajó (40 MW), Cañada de Gómez (36 MW) and Santa Rosa Sur (30 MW). Behind Genneia, DQD Energy took eight sites, 360 Energy three, and Aluar and Intermepro Generación one each.

A blowout auction, and $700M of capex

The auction drew 235 offers from 37 firms totaling 8,338 MW — nearly twelve times the 700 MW target — and set an estimated $700 million of new investment for the first phase. Genneia's winning floor was around US$7,397 per MW-month, well below the highest allowable bid, and pulls in equity partners including Central Puerto, PCR, MSU, Secco, Coral Energía and Edison Energía across the bidding pool.

Argentina joins the global BESS build-out

The AlmaSADI awards echo a broader wave of utility-scale storage procurements. Just this week, BYD and Greenvolt signed Poland's largest 600 MW / 2.4 GWh BESS deal, while Ore Energy and Budget Thuis inked Europe's biggest iron-air deal. Grid-scale batteries are quickly becoming the front-line asset class of the energy transition.
