The company committed to complete documentation for communications, commercial measurement and real-time operation systems mandated by Cammesa. Environmental approval came August 13 from the Buenos Aires province Environment Ministry. The market entry request was published September 8 and drew no objections that would block authorization, according to the resolution.
BESS Brown was incorporated into the AlmaGBA tender in October 2025 alongside the 24 MW BESS Chingolo Sull, bringing total awarded capacity in the program to 713 MW. BESS Brown accepted a price of 12,591 dollars per MW-month and appeared in the award associated with Rowing. Alma Energía was established in September 2025 with Rowing as majority shareholder, subscribing 25 million of the company’s 30 million initial shares.
The resolution establishes that Cammesa will charge Alma Energía for any excess costs caused to other market agents and penalties corresponding to technical transport function providers for unavailability stemming from the BESS system’s entry to the grid. The authorization arrives as Argentina introduced September 25 new demand rules requiring projects above 80 MW to secure their own generation capacity, with data centers facing a 115 percent firm capacity requirement. Industry discussions at the September 16-17 Energyear Argentina conference identified transmission capacity, bankable contracts and operational risk as the three binding constraints for the next expansion phase, with storage deployment timelines of nine months contrasting sharply against five-year grid build cycles for works like the 2,000 MW AMBA I corridor.
