Power supply options dwindle for Peru's Loreto region

Thursday, October 5, 2017

Plans to diversify electricity supply to Peru's Loreto region in the northern Amazon may be at risk, BNamericas has learned.

The energy and mines ministry's energy environmental affairs office (DGAAE) did not approve the detailed EIS submitted by the Loreto regional government's public infrastructure agency (OPIPP) for the US$1.21bn, 544MW Mazan hydro project.

The document does not fulfill technical and legal requirements for power sector activity, according to a DGAAE resolution, which highlights that the EIS requires greater clarity regarding flora and fauna, and demographics, among other shortfalls.

OPIPP may file a new environmental document for Mazan, which would take five years to build and envisions one 100MW machine house and another for 444MW, which will use water from the Mazan and Napo rivers. Works include a 2.9km water channel and transmission infrastructure.

Meanwhile, information from energy and mining investment regulator Osinergmin reveals that Isolux-controlled Líneas de Transmisión Peruanas may be evaluating the termination of the concession contract for the Moyobamba-Iquitos transmission project.

The US$499mn, 220kV line would stretch 596km and connect Loreto capital Iquitos' isolated system with the national grid.

Osinergmin adds that the project missed its environmental and financial closure deadlines, which expired in June and August, respectively. The start of commercial operations is scheduled for December 2019.

Loreto's near term solution to shore up its energy infrastructure now falls on the 70MW Iquitos Nueva thermoelectric plant which is scheduled to begin commercial operations this month.

Investment promotion agency ProInversión awarded Genrent del Perú the project in 2013 to replace antiquated and obsolete generation units.

In a first stage, the plant will provide regular supply until Moyobamba-Iquitos comes online, and then convert to cold reserve.
