In the SING, meanwhile, the marginal cost increased by 30% compared to November 2014.
Marginal Cost in the SIC fell by 59%.
SIC
During November the marginal cost of the SIC in the Alto Jahuel 220 busbar averaged US$37.5 per MWh, a figure 58.5% lower compared to the same month in 2014 (US$90.4 per MWh), and 4.5% lower compared to the previous month (US$35.8 per MWh), according to Systep’s latest report.
“Marginal costs continue to be low in the SIC, during November these were mainly determined by coal-fired power plants,” the consultant explained.
In November, the SIC operation was characterized by a hydroelectric participation of 69%, which is 13% higher than the previous month (56%) and 11% higher than the same month last year (58%).
While coal-fired participation fell by 8% compared to the same month and by 3% compared to November 2014.
Meanwhile, the participation of LNG and diesel (0.5% and 0.3%) was practically nil this month “due to low marginal costs and lower LNG availability”, according to Systep.
“In the next 12 months, 1,708 MW of new renewable capacity is expected to come into operation, of which 1,374 MW are solar, 112 MW wind, 167 MW hydro, and 55 MW of cogeneration. In addition, the entry of the Guacolda V coal-fired power plant is considered for this projection period”, they add.
SING
Meanwhile, in the SING, the average monthly marginal cost for November in the Crucero 220 busbar was US$75.1 per MWh, which represents an increase of 4.9% with respect to October (US$71.6 per MWh), and an increase of 30% with respect to November 2014 (US$57.9 per MWh).
Likewise, the SING operation in November showed an LNG generation share of 12%, which represented a decrease of 10% compared to the previous month (22%) and did not register any variation when compared to the same month of 2014.
This was offset by higher coal and diesel generation (78% and 6%). It is worth noting the increase in solar participation in the SING, which varied from 0.8% in November 2014 to 3% in November this year, a figure similar to that recorded the previous month.
“November’s marginal costs in low demand were marked by coal in low demand, while in high demand the marginal technology was diesel,” the consulting firm said.
Regarding generation projects, “within the next 12 months the entry of 372 MW NCRE is expected, where all of them correspond to solar projects. Regarding conventional technologies, the entry of the Cochrane I power plant (coal, 266 MW) is expected in January 2016, while Cochrane II (coal, 266 MW) and Kelar (CC-GNL, 540 MW) will enter in May of the same year”, according to Systep.
