Why map power infrastructure in the Philippines?

Power lines, whether they are the transmission lines from power plants to large substations, the sub-transmission lines from the large substations to a city's/municipality's substation (there may be more than one substation, some serving industrial customers), and the distribution lines from a city's/municipality's substation to houses and businesses, can be landmarks when navigating. Also, mapping power lines and facilities depicts the pathways of power from a power plant to its customers, whether it is an ordinary house or a large factory using large equipment requiring a higher voltage of electricity to work.

Power lines by voltage

Voltage class Voltage Image Supports (pole/tower) Description Tags
Low voltage 220/440 volts (Split-phase) Poles Two cables or bare wires, carrying a phase to neutral voltage of 220 V 60 Hz and phase to phase voltage of 440 V 60 Hz (Split-phase power is primarily used in North America, but used here in the Philippines as an American influence; however, using a higher voltage of 220 V 60 Hz over the 120 V 60 Hz in the US). Supported by wood, concrete or steel poles. Used to carry power for household distribution and street lightning.

power=cable
location=overhead
voltage=440
or
power=minor_line
voltage=440

220/380-440 volts split/three phase (three-phase high-leg delta) Three single cables with one neutral wire, usually grounded from a tap from a distribution transformer), carrying a split-phase voltage of 220/440 V 60 Hz, three-phase voltage of 440 V, 60 Hz, and phase B to neutral voltage of 380 V. Only used on transformers, that may be one or two single-phase transformers.
Medium voltage 7390 volts (7.39 kV) Poles Standard voltage on most single-wire (single-phase) distribution lines, mostly cooperative-owned, but also used by Meralco on some areas, with the line fed by a 13.8 kV two or three-wire line. minor_line
13,800 volts (13.8 kV) Poles Standard voltage on most two or three-wire distribution lines, mostly cooperative-owned, but also used by Meralco on some areas, including predominately 20/34.5 kV areas (through a pole-mounted three-phase isolation transformer). Lines of this voltage use one or two-cap pin insulators and two-cap strain insulators. minor_line, cable
20,000 volts (20 kV) Poles Voltage for single-phase primary distribution lines, primarily in residential areas. minor_line

voltage=20000 operator=name of operator of line (e.g. Meralco)

34,500 volts (34.5 kV) 0811jfAurora Boulevard Santa Cruz Overpass Bridge Streets Barangaysfvf 10.jpg Poles Standard voltage for two to three-wire distribution lines owned by Meralco in most areas. Sometimes, they can be insulated cables, mounted on poles, e.g. like when it cannot cross an obstacle on the level where they should pass, or placed underground, e.g. to avoid clutter on scenic locations. minor_line, cable
High voltage 69,000 volts (69 kV) Wooden, concrete or steel poles, with insulators hanging from crossbars or mounted on the pole itself, or sometimes, wooden, concrete, or steel H-frame towers. Sub-transmission grid voltage. Usually single-circuit lines with 3 wires supported by strain insulators hanging from 2 or 3 crossbars mounted on poles. Primarily owned by the National Grid Corporation of the Philippines and provincial electric cooperatives.
115, 000 volts (115 kV) Tagaytayjf9771 08.JPG
  • Sub-transmission poles, mainly made of steel, concrete, or wood, usually with insulators attached to the pole itself, or rarely, with insulators hanging from a cross-arm, usually on two levels.
  • Lattice towers (used on the San Esteban - Bantay, Bantay - Currimao, and Currimao - Laoag transmission lines)
Typically sub-transmission voltage, primarily used by Meralco, but also used by NGCP on some transmission lines in Ilocos Region, supplying the main load centers power, and a few sub-transmission lines. Cables can be a single conductor or double-bundle. In the case of Meralco's subtransmission system, distribution lines may share the poles of the 115 kV lines through [a] cross-arm[s] and distribution transformers may be supported on the subtransmission poles.
138,000 volts Lattice towers Used on the Visayas and Mindanao grids.
Ultra high voltage 230, 000 volts (230 kV) 02828 jfSan Luis Roads Fields Mangga Dalayap Tenejero Barit Candaba Pampangafvf 29.JPG Lattice towers, or tubular steel towers (for aesthetic purposes in order to reduce visual impact on the surroundings) Typically double or single-circuit lines. Conductors are usually double-bundle, but single conductor or quadruple-bundle are also used. Voltage is used as a "backbone" voltage on the Visayas and Mindanao grids, however, according to NGCP, the Mindanao 230 kV transmission backbone lines are still energized at 138 kV. Even Bing and Mapbox Satellite imagery of the terminal substations of those backbone lines have no evidence of 230/138 kV transformers.
350,000 volts (350 kV) Towers (steel lattice) Used on the Leyte-Luzon high voltage direct current transmission line/underwater cable (HVDC Leyte-Luzon)
500,000 volts (500 kV) JfSanMiguel8745SalanganBulacanfvf 11.JPG Lattice towers Voltage for long distance high voltage AC "backbone" lines in Luzon, like the Dasmariñas-Alaminos (-Ilijan Power Plant) - Tayabas transmission line, Tayabas - San Jose del Monte transmission line, and the San Manuel - San Jose del Monte transmission lines. Lines are composed of quadruple-bundle conductors, supported on very tall towers, and phases are transposed on some places.

Meralco

Meralco, or Manila Electric Company (website: www.meralco.com.ph), which distributes electricity in Metro Manila and nearby provinces, operates a subtransmission system composed of lines between large transmission substations and distribution substations on areas it serves. Sub-transmission lines operated by Meralco are typically mounted on tall poles and are roadside for easy access by work vehicles, but a few run on allocated right-of-way, and mounted on both towers and poles. The voltage of subtransmission lines operated by Meralco are typically 115,000 volts, but 69,000 volts in a few places, like in Batangas City and parts of Bulacan.

National Grid Corporation of the Philippines (NGCP)

The National Grid Corporation of the Philippines (website: ngcp.ph), also known as NGCP, operates the main power grid that carries electricity from power plants to substations, before distribution to electric utility companies, like Meralco, Davao Light, and Visayas Electric Company, and provincial electric cooperatives. NGCP is formed as a private company given by the government-owned National Transmission Corporation (Transco) a 50-year concession to operate and develop the Philippine power grid. The transmission lines owned by NGCP have voltages of 115,000 volts DC, 138,000 volts AC, 230,000 volts AC, and 500,000 volts AC, but one line, the HVDC Leyte-Luzon, carries ±350,000 volts DC. NGCP also operates a subtransmission system, typically 69,000 volts, that brings electricity to cooperative/utility owned substations, although cooperatives/utilities may own and operate their own subtransmission lines. NGCP's power grid is divided into three grids, the Luzon Grid, Visayas Grid, and Mindanao Grid, with only the former two interconnected, via the HVDC Leyte-Luzon, but as part of its plan, additional links between the three grids are being proposed and constructed.

Power features

This section shows tags for power-related infrastructure, like power plants (also called power stations), generators, substations, transmission lines and towers, utility poles, distribution lines, and transformers.

  • Power plants/stations=power=plant. Do not tag them as power=station.
  • Transmission towers=power=tower. Add the tower designs and types if possible. Tubular towers are also counted as towers, just tag them as normal towers with the structure=tubular tag. Do not tag them as power=pole, as they are reserved for poles holding distribution lines (220/440 V-34.5 kV)
  • Sub-transmission poles=power=tower. This tagging distinguishes them from the smaller poles, tagged power=pole, holding distribution lines, usually 13.8-34.5 kV three-phase AC lines or local 220/440 V split-phase AC lines.
  • Utility poles=power=pole. Tag their height, material, and operator if possible.
  • Transformers=power=transformer. Tag the type, phases, rating and voltages if possible. For pole-mounted transformers, please tag as power=pole with transformer=distribution, plus other tags mentioned on the previous sentence if possible.
  • Transmission lines (115/138 kV and above)=power=line (If undersea cable, tag as power=cable
  • Sub-transmission lines (69 to 115 kV)=power=line. This tagging is preferred over power=minor_line, as in this case, should be reserved for lines with voltages below 50 kV.
  • Distribution lines (220/440 V split-phase to 13.8-34.5 kV)=power=minor_line. If it is an overhead or underground insulated cable, tag as power=cable, plus relevant information, like circuits, voltage, and location.
  • Distribution circuits=type=route and d route=power. Tag circuit references with ref=*. Distribution circuit references can be found in outgoing distribution lines at a substation (especially when feeders transition from underground cables in the substation) , poles at crossings between lines forming circuits, insulated overhead cable bundles, and disconnector switches).

Tower designs

Transmission tower designs may be tagged using the design=* tag

Design Images Description Tags
Steel three-level tower JfSanMiguel8745SalanganBulacanfvf 12.JPG

Lemery,Agoncillo,Batangasjf4631 18.JPG

Tower with cross-arms on three levels. This design is common on most transmission lines usually double-circuit, but also used occasionally on single-circuit lines. Toowers or poles with "armless" construction (insulators mounted on the tower/pole itself), but with insulators placed on both sides, should be tagged as such. design=three-level

structure=*lattice or tubular material=steel
