Argentina Grants 700 MW Battery Storage Boost
Argentina awarded 700.5 MW of battery storage in a $700 million tender
Argentina’s Energy Secretariat officially granted 20 battery‑energy‑storage system (BESS) projects totaling 700.5 MW to five developers, with an estimated investment of US$700 million. The award was confirmed by Resolution 155/2026 and covers critical nodes of the Argentine Interconnection System (SADI) outside the Buenos Aires metro area.
The projects are split among Genneia (7 projects), DQD Energy (8), 360 Energy Solar (3), Aluar (1) and Intermepro (1) and are spread across seven regions – Buenos Aires province (185 MW), Northwest (150 MW), Chaco‑Formosa (161.5 MW), Misiones‑Corrientes (50 MW), Entre Ríos (50 MW), Santa Fe (36 MW) and the Pampa (68 MW) (https://www.pv-magazine.com/2026/05/28/la-licitacion-de-almacenamiento-de-argentina-recibe-235-ofertas-por-mas-de-8-300-mw/).
The tender drew 11‑times more capacity than the 700 MW target
CAMMESA, Argentina’s wholesale market operator, received 235 technical bids totalling 8,338 MW, more than 11 × the requested amount. After a technical screening that qualified 232 bids, financial proposals were opened on 24 June, leading to the final award. The massive oversubscription signals strong private‑sector confidence in Argentina’s grid‑flexibility market and the attractiveness of BESS revenues under the country’s regulatory framework (https://www.ess-news.com/2026/06/18/argentina-advances-232-battery-bids-in-almasadi-tender/).
Winners submitted the lowest weighted‑average bid price of US$10,568 per MW‑month
The five selected developers secured the contract with a weighted‑average bid price of US$10,568 per MW‑month. Multiplying by 12 gives roughly US$126,800 per MW‑year, a benchmark that analysts say reflects the current cost of providing fast‑response, dispatchable capacity in Argentina (https://www.bnamericas.com/en/news/genneia-dqd-energy-big-winners-in-argentinas-700mw-almasadi-auction).
Investment per megawatt comes to about US$1 million, underscoring the scale of the program
Dividing the total US$700 million budget by the awarded 700.5 MW yields an average investment of roughly US$1 million per MW of storage. This figure is useful for benchmarking against other large‑scale storage programmes worldwide and shows that Argentina is committing capital comparable to the cost of utility‑scale lithium‑ion projects in Europe and the U.S. (https://energy-analytics-institute.org/2026/07/06/argentina-awards-almasadi-tender-for-battery-storage-plants/).
The award builds on Argentina’s earlier AlmaGBA tender and a national storage roadmap
AlmaSADI follows the 2024‑2025 AlmaGBA tender, which awarded 713 MW of battery storage inside the Buenos Aires metropolitan area – already exceeding its 500 MW goal. Both tenders are part of a government programme launched in 2024 to relieve transmission bottlenecks, improve operating reserves and reduce outage risk across the SADI network (https://www.pv-magazine.com/2026/05/28/la-licitacion-de-almacenamiento-de-argentina-recibe-235-ofertas-por-mas-de-8-300-mw/).
What it means for Israel’s solar‑plus‑storage market
Israel is rapidly adding battery storage to complement its booming rooftop‑solar sector. Using the typical Israeli residential tariff of ₪0.48 /kWh and a 10 kWp home system that yields about 17,000 kWh / year (≈₪8,160 of annual revenue), adding storage can increase the value of that generation by shifting energy to higher‑price periods. With a typical installation cost of ₪3,150 /kWp for solar and the Argentine benchmark of roughly US$1 million per MW for utility‑scale storage, such projects can offer attractive payback periods, aligning with the economics observed in Israeli storage deployments.
For Israeli investors, Argentina’s tender demonstrates that large‑scale, fast‑response BESS can be procured at a cost that is competitive with domestic projects, supporting the country’s push toward its 30 % renewable electricity target by 2030.
Outlook: scaling storage to match renewable growth
With Argentina now securing 700 MW of battery capacity outside its capital, the country is poised to integrate more intermittent solar and wind generation while curbing blackouts. The tender’s success may encourage other Latin‑American markets to launch comparable programmes. In Israel, the combination of affordable rooftop solar (≈₪3,150 /kWp) and increasingly competitive battery costs could accelerate the transition to a more resilient, low‑carbon grid, especially as regulators continue to refine incentives for storage‑enabled demand response.
