The solar development arm of the
Aboitiz group is seeking regulatory approval for the installation of dedicated
point-to-point limited transmission facilities that shall support the wheeling
of capacity generated from its 48.6-megawatt San Carlos utility-scale solar
farm in Negros Occidental.
The investment for the proposed
transmission assets, as indicated by Aboitiz corporate vehicle San Carlos Sun
Power, Inc. (SACASUN) in its filing with the Energy Regulatory Commission
(ERC), amounts to P84.373 million – inclusive of relay protection, fiber optic
communication system as well as interconnection system.
The ERC has scheduled hearings and
presentation of evidence on this application on February 22 this year.
SACASUN, in particular, has prayed
that “pending hearing, a provisional authority be immediately issued
authorizing SACASUN to start implementing the project for the Connection
Assets.”
It stressed “the grant of
provisional approval will allow SACASUN to immediately start with the
construction of the connection assets to enable the plant to be commissioned by
March 2016.”
The solar facility – which is the
Aboitiz firm’s joint venture with American firm SunEdison, is targeted for
commissioning March this year – in time for the prescribed cut-off on availment
of the offered second wave of feed-in-tariff incentives.
As stipulated in the regulatory
filing, “the plant will be connected to the grid by a two-point tap connection
along the San Carlos-Guihulngan 69kV (kilovolt) transmission line.”
It emphasized that “under normal
operating conditions, part of the plant’s output will be injected towards the
south portion of the line (which shall be its first connection point) and the
other portion towards the north portion of the line (the second connection
point).”
The project company added that “the
connection of the plant to the grid was subjected to a system impact study
(SIS),” which is currently under review by the National Grid Corporation of the
Philippines.
“Based on NGCP’s initial review of
the SIS, using the two-point connection scheme, the connection of the plant to
the grid, particularly its simultaneous power delivery to Cadiz and Amlan, is
technically feasible,” SACASUN noted.
