Mostly coupled week with oil peaks in the south
|
|
|
|
The average price at Polpaico reached USD 33.2/MWh, 13% lower than last week and 38% lower than the same week a year ago. The average variable cost for dam units fell to USD 63/MWh from USD 80/MWh, contributing to the weekly price decrease.

Marginal cost evolution in Polpaico during past years
|
|
|
|
|
|
|
In the generation mix, renewables showed mixed movements: run-of-river edged down by 0.1 pp, wind rose by 0.9 pp, solar increased by 0.2 pp, and dam declined by 0.7 pp. Among thermal sources, coal gained 0.6 pp, gas decreased by 0.7 pp, and oil dipped by 0.1 pp.
|
|
The system’s weekly peak demand reached 12.7 GW on Monday at 2 PM; at that time, wind and solar covered 74.9% of output. BESS peak injection was 1.6 GW on Wednesday at 9 PM.

Prices were mostly coupled across the reference zones, with the usual exception of Puerto Montt. The node decoupled for several hours each day, most often due to congestion in the 220 kV Lastarria - Ciruelos line. From Monday through Wednesday, peak prices in Puerto Montt were set above USD 200/MWh by the oil‑fired Trapén plant.
|
|
There was also brief congestion in the 500 kV Nueva Pan de Azúcar - Polpaico line on Tuesday and Wednesday, decoupling the northern reference nodes Pan de Azúcar, Cardones, and Crucero, with prices at zero.
|
|
The weekly peak marginal cost among reference nodes was USD 236.4/MWh in Puerto Montt on Tuesday at 10:45 AM.

Solar and Wind production & BESS dispatch
|
|
Solar generation decreased by 2.4% (-12.5 GWh) this week. The highest solar plant factor was in the Polpaico zone (26.5%), and the lowest was in Pan de Azúcar (23.8%). The system-wide solar plant factor was 25.1%.
|
|
Wind generation increased by 4.0% (+8.6 GWh) compared to last week. The highest wind plant factor occurred in Charrúa (23.1%), while the lowest was in Polpaico (12.6%). The system-wide wind plant factor reached 20.5%.
|
|
BESS discharges dropped by 2.2% (-1.3 GWh) versus last week. The largest percentage decline was observed in Charrúa, with a 12.4% reduction in discharges. In total, BESS injected 59.0 GWh this week.
|
|
This week’s curtailment rate was 17.3% for wind (47.1 GWh) and 20.9% for solar (127.4 GWh), resulting in a system-wide curtailment rate of 19.3%.
