Chile's electric power and fuels regulator SEC is investigating a power outage on the northern SING grid that affected nearly 90% of clients on Wednesday.

The interruption occurred at 11:45am, and was caused by a failure at generator E-CL's Crucero substation, the regulator said in a statement.

Power supply was fully restored by around 5pm, according to grid operator CDEC-SING.

The outage left more than 270,000 homes without electricity.

SEC head Luis Ávila was quoted saying that the interruption was not caused by structural problems, nor a lack of generation capacity.

If it is determined that a regulatory violation occurred, Ávila said the punishment could range from a reprimand to a fine of up to 10,000 UFs (inflation-indexed units, US$434,917).

The SING covers 185,142km2 in Chile's three northernmost regions – Arica, Tarapacá and Antofagasta – with mining companies and other industrial clients accounting for about 90% of demand.

Argentina's planning ministry announced it helped cover demand in northern Chile with 126MW available from Termoandes' Salta province connection which can be increased to 300MW.
