The National Grid Corporation of the Philippines (NGCP) is set to begin constructing a new transmission line in Cebu which is expected to be completed in 2014. This project is in line with NGCP’s plan to strengthen the Cebu grid.
The project, which is part of the Henry Sy-led grid operator’s 2012 Transmission Development Plan, has an Energy Regulatory Commission-approved budget of P602 million.
In 2012, NGCP embarked on the construction of a 138-kilovolt (kV) transmission line that would connect two of its substations in Cebu—Colon and Calung-Calung.
NGCP explained that the connectivity of Colon to Calung-Calung is essential to increase the transfer capability of the grid for Cebu Energy Development Corp.’s (CEDC) coal-fired power plant in Toledo, Cebu.
The CEDC plant, with a total capacity of 246 megawatts (MW), is connected to the grid through NGCP’s Colon Substation.
The project includes the construction of a 28-kilometer transmission line and installation of additional power circuit breakers and corresponding accessories at the aforementioned substations.
Rico Vega, NGCP deputy assistant chief technical officer for planning and engineering, said that the original design of the project involves connecting the Colon and Calung-Calung substations with the Toledo substation, which is in the middle of the two facilities.
Because of space constraints in the Toledo substation, NGCP had to redesign the project and bypass Toledo substation, thus connecting the Colon facility directly to the Calung-Calung substation.
“The project will not only increase NGCP’s transfer capability but will also accommodate the future entry of Toledo Power Co.’s coal-fired plant,” Vega said.|
“NGCP sees to it that it continuously improves its customer service to generation companies and distribution utilities, by creating new corridors to welcome new entrants in the power industry,” he added.
