High renewable participation coincides with record BESS charging
|
|
|
|
The average price at Polpaico was USD 23.6/MWh, 21% higher than last week and 33% lower than the same week last year.

Marginal cost evolution in Polpaico during past years
|
|
|
|
|
|
|
Among hydro sources, run-of-river and dam generation decreased their shares by 1.9 pp and 0.9 pp, respectively. Solar and wind increased by 1.3 pp and 1.2 pp, respectively, while BESS participation rose by 0.4 pp. Coal share decreased by 0.4 pp.
|
|
The system peak output occurred on Thursday at 12 PM, reaching 11.7 GW. The highest BESS participation was recorded on Saturday at 11 PM, when injections accounted for 27.3% of system output.
|
|
The highest BESS charging was recorded on Saturday at 12 PM, reaching 3.6 GW and setting a new charging record. The highest combined solar and wind participation occurred on Sunday at 11 AM, reaching 73.6% of the 9.9 GW system output.

Prices decoupled in two main areas during the week. Between the Charrúa and Puerto Montt zones, recurring congestion in the 220 kV Lastarria - Ciruelos line kept Puerto Montt prices above those in the rest of the system every day except Friday and Sunday. On Sunday, congestion in the 500 kV Charrúa - Ancoa line kept prices at Charrúa and south of it at USD 0/MWh until the afternoon.
|
|
Oil-fired plants set the marginal price in Puerto Montt from Monday through Thursday. The highest reference price was USD 353.9/MWh in Puerto Montt at 6 PM on Thursday, set by the oil-fired Trapén plant, according to preliminary CEN sources.

Solar and Wind production & BESS dispatch
|
|
Solar generation increased by 6.5% | 22.9 GWh relative to last week. The highest solar plant factor was 21.3% in Charrúa, while the lowest was 16.4% in both Crucero and Pan de Azúcar. The system-wide solar plant factor was 17.1%.
|
|
Wind generation decreased by 8.7% | 21.9 GWh. The highest wind plant factor was 34.8% in Cardones, while the lowest was 10.0% in Polpaico. The system-wide wind plant factor was 23.6%.
|
|
BESS injections increased by 5.4% | 7.3 GWh, with the largest volume recorded in the Crucero zone, totaling 104.4 GWh.
|
|
Curtailment reached 15.0% | 79.5 GWh for solar and 11.4% | 35.5 GWh for wind, resulting in a combined system-wide curtailment rate of 13.4%, 3.8 pp down from last week.
