SIC: energy cost amount of three months under the U.S. $ 100 per MWh
Electricity at node 220 kV Quillota averaged U.S. $ 69.3 in November
For the third consecutive month, the marginal costs of electricity in the Central Interconnected System (SIC) were traded below $ 100 per MWh on average, representing a dramatic drop from the regular levels coming observed in the market SIC spot. In November, according to official figures from the CDECSIC, the average marginal cost in the reference node 220 kV Quillota averaged U.S. $ 69.3 MWh, which in turn is the lowest since 2009.
Thus, there are now three consecutive months in which the spot market is below the $ 100 a MWh, since it fell 53% per month in September, reaching that month an average of U.S. $ 96 per MWh in the reference node .
This low price is due to a mix of good levels of snowmelt, despite low levels of rainfall in the central region, fell much snow in the high-sectors that have increased hydroelectric generation, which adds SIC joining the more than 1,000 MW in efficient coal capacity between central Santa Maria (Colbún) Campiche (AES Gener) and Bocamina II (Endesa).
Thus, the plants operating with diesel have remained dispatch, which in turn allows the costs are kept at bay, as the marginal cost is marking by coal product that is cheaper than gas and diesel.
What will happen in the coming months? Ramón Galaz, Valgesta Consulting Firm’s CEO raised at the last monthly report of the governing body that this cost into the system should be stable at least for the next few months as the conducive conditions are maintained.-
Galaz added that this phenomenon is due to the greater availability of water have added low point in other fuels. “It’s important recovery in reservoirs, especially the smaller ones by the thaw. We have had episodes of high temperature which helped this situation and the CDEC-SIC availability has handled that well, “said Galaz.
