Power Grid Status

Most power transmission lines are owned and/or operated by the National Grid Corporation of the Philippines, while power generating sites are owned by various companies. It is currently divided into three grids: the Luzon Power Grid, the Visayas Power Grid, and the Mindanao Power Grid. They are further subdivided into dozens of transmission lines, which carry up to 500 kilo volts of energy.

Minor lines are mostly operated by Meralco (Manila Electric Company) and local electric cooperatives/companies, which also operate transmission lines between substations within their power networks and the main power grid by NGCP. The minor lines feed power from the substations to residential and industrial users (although some industrial users also feed power from the transmission lines operated by Meralco or local electric cooperatives/companies).


TODO: Add more guidelines on mapping power facilities and power lines

  1. Power generators/power plants are sometimes called "power stations". Do not tag them as power=station. Instead, tag them as power=generator.
  2. Power stations are individually named (in most cases) and are called "substations" (e.g. "San Jose del Monte Substation"). Do not tag them as power=sub_station. Instead, tag them as power=substation.
  3. Sub-transmission lines (69 kV to 115 kV, except for two lines in Ilocos Region, which are transmission lines instead) mounted on tubular steel, concrete, or wood poles, usually shared with minor power lines and telephone/cable television lines, like those owned by the National Grid Corporation of the Philippines, Meralco and some electric cooperatives/companies on most provinces, are to tagged as power=tower, with structure=tubular (if steel) or structure=solid (if wood or concrete) and the specific tower design, commonly flag, triangular, H-frame, or asymmetrical, depending on the arrangement of the cables and insulators on the pole, whether the insulators are mounted on a crossbar or on the pole itself. The tagging of sub-transmission poles as power=tower helps distinguish them from smaller poles used for distribution lines and the tagging is correct as towers (whether they are the usual lattice type, tubular steel, or wood/concrete pole) holds power lines above 50 kV, or the power grid voltages (for the Philippines, grid voltages are 69 kV, 115 kV, 138 kV, 230 kV, 350 kV (used only on HVDC Leyte - Luzon), and 500 kV, somewhat close to the voltages used on the US power grids.) Some utility poles have designs other than the usual crossbar mounted insulator type, like flag, triangular, or asymmetrical (with insulators mounted on the pole or on an adaptor made from crossbars typically found on most poles) but they should be tagged with power=pole. Insulators or crossbars only carrying ground wires should not be considered when tagging design of a sub-transmission pole or utility pole.
  4. Power lines below 69 kV (e.g. 20 kV) should be mapped as power=minor_line. If line has voltages higher than 69 kV, they should be mapped as power=line. The frequency of the power grid in the Philippines is 60 Hz, except high-voltage direct current, like the HVDC Luzon Leyte, which should be tagged with frequency=0, used to mark HVDC or DC contact lines or third rail used for railways and rapid transit systems.
