- Angamos and Cochrane entered daily monitoring on October 23, 2026, covering 1,108 MW.
- AES Andes operates 4,079 MW in Chile, including 756 MW of batteries, as of August 2026.
- The AES transaction is expected to close in late 2026 or early 2027.
AES Andes (CL0000001140) has 1,108 MW of coal capacity at its Angamos and Cochrane plants under daily monitoring after a port failure. Energia Futura reported on October 23, 2026, that the grid operator's measure is preventive and that the plant has not run out of fuel.
Port disruption reaches 1,108 MW
The daily reporting requirement covers coal inventories, projected shortages, vessel arrivals and alternative supplies after restrictions at the Terminal Graneles del Norte in Mejillones. Angamos and Cochrane together have about 1,108 MW of installed capacity, although installed capacity does not equal the power dispatched to the grid.
The immediate issue is logistics rather than a confirmed generation outage. The operator is reviewing whether coal can be transferred between the two plants, while daily reports began on October 22, 2026.
What does ownership change mean?
Chile's antitrust regulator cleared the takeover of AES Corporation, the parent of AES Andes, on October 22, 2026. Energia Futura said the clearance was unconditional and covered generation, transmission, battery storage and data centers. The transaction is expected to close in late 2026 or early 2027.
Three events shape the timeline
On March 2, 2026, AES announced a cash offer of USD 15.00 per share for the parent company. On October 22, 2026, Chile's FNE cleared the transaction, while AES Andes reported 4,079 MW of installed capacity in Chile, including 756 MW of batteries, in August 2026. On October 23, 2026, the Angamos monitoring requirement put 1,108 MW of coal capacity under daily operational review.
Which dates matter next?
The next disclosed timing is late 2026 or early 2027 for the expected transaction closing. The CNE's planning studies use October 2030 as a reference for possible coal retirement, subject to system security and adequacy conditions.
Capacity remains the investor lens
The ownership process does not currently change AES Andes' stated Chilean operating plan. Its investor-relations page describes 5.5 GW of operating capacity across Chile, Colombia and Argentina and more than 4.1 GW of wind, solar, hydroelectric and battery capacity to be added between 2019 and 2027, according to AES Andes. For investors, the key tension is clear: renewable and storage growth is expanding the portfolio while coal logistics remain a live operating constraint.
