Why map power infrastructure in the Philippines?

Aside from being an ubiquitous sight, even on urban aread, power lines are very important infrastructure, and imagine where the power we use come from, that is, power plants, and flows into our houses, businesses, and factories via transmission, subtransmission, and distribution lines. Also, power lines are not mapped in detail in most of the Philippines, except in the majority of Luzon, which has a large grid, and on OpenStreetMap, even major transmission lines are missing, especially in most of Visayas and Mindanao, which have grid systems also.

What interests me is Meralco's 115 kV subtransmission system, which are a large network serving substations and some large industrial customers around Metro Manila, Rizal, southern Bulacan, Laguna, and Cavite. It is composed of mostly roadside lines, placed on tall wood, concrete, or steel poles, with heights of 21 to 32 meters and usually shared by the distribution feeders. And mostly placed on major roads, these may serve as a guide or landmark, though in scenic areas, these are making the view cluttered. The lines of Meralco's subtransmission network are not very much mapped, unlike NGCP's 230 kV transmission lines traversing Metro Manila. and mostly looked upon like the lines placed on smaller poles, (usually rising at 13.5 to 15 meters), though they are energized at 115,000 volts, placed on poles with taller heights (21, 27.5 or 32 meters), and sometimes, double-bundled to carry the same power an unbundled single-circuit 230,000 volts line transmits.

Power lines by voltage

Voltage class Voltage Image Supports (pole/tower) Description Tags
Low voltage 220 (nominally 240, single phase) poles Two wire system, with one wire used as neutral. System commonly used for domestic distribution in most provinces. Supplied via single-phase pole-mounted transformer
220/440 volts (Split-phase) Poles Three cables or bare wires, with one wire serving as neutral. Common in private utility-owned systems.

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

220/380-440 volts split/three phase (nominally 240/415/480, three-phase high-leg delta) Poles (rare) Three or four wire grounded delta three-phase system, usually supplied from two pole-mounted transformers. Mostly used for larger commercial service.
Medium voltage 4,800 volts /2,800 volts Poles Distribution voltage still used on some areas of Metro Manila, and fed by the 34.5 kV system. Most of these systems are already obsoleted (customers connected to 4.8 kV systems being reconnected to the 34.5 kV system, 4.8 kV lines below 34.5 kV lines discarded, or 4.8 kV-only lines replaced by 34.5 kV lines), but still exist on parts of Manila, Pasay, Quezon City, and Parañaque. Transformers of 2.8/4.8 kV lines are distinguishable from those in 34.5 kV lines by having bushings on the side rather than on the top.
7620 volts (7.62 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
13,200 volts (13.2 kV) Poles Standard voltage on most two or three-wire distribution lines, mostly cooperative-owned, but also used by Meralco on some areas, like in southern Cavite (fed also by the 115 kV suntransmission grid, parts being fed by 34.5 kV system through step-down facilities, some being converted to 34.5 kV), northern Bulacan, and Batangas City San Pascual in Batangas, and. Lines of this voltage use one or two-cap pin insulators and two-cap strain insulators, but in the case of Meralco's 13.2 kV network, 34.5 kV pin insulators and three-cap strain insulators are becoming common, replacing one or two-cap pin insulators and two-cap strain insulators. Distribution transformers of this voltage may have one or two bushings, but it is typically two bushings (usually one connected to the line and one connected to ground, or both connected to the primary). minor_line, cable
20,000 volts (20 kV) Poles Voltage for single-phase primary distribution lines, primarily in residential areas. minor_line

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) Famy,Lagunajf9888 04.JPG Wooden, concrete or steel poles or H-frame towers, or rarely, steel lattice towers and tubular steel towers. Subtransmission grid voltage. Usually single-circuit lines with 3 wires supported by strain insulators hanging from 2 or 3 crossbars mounted on poles, but double-circuit lines may exist. 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 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 northern 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, mostly constructed by themselves or divested from NGCP. 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 or solid towers, excluding such structures used for subtransmission voltages (115 or 69 kV), which are considered poles instead (except for multipolar structures, which are considered towers), are also counted as towers, just tag them as normal towers with the structure=* tag.
  • Subtransmission and distribution poles=power=pole. Tag their height, design, material, operator, and other details (e.g. guy wires are present, uses strain insulators, or has street lights), 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. The values at power transformer expanded tagging will replace several values documented in power=transformer, but does not mean everything must be mechanically retagged.
  • 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 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), insulated overhead cable bundles, and disconnector switches).

Tower designs

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

Design Images Description Tags
Three-level tower JfSanMiguel8745SalanganBulacanfvf 12.JPG

Lemery,Agoncillo,Batangasjf4631 18.JPG Bay-Binan Transmission Line, Sto. Tomas, Batangas.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. Towers or poles with "armless" construction (insulators mounted on the tower/pole itself and functions also as a cross-arm), but with insulators placed on both sides, should be tagged as such. design=three-level

structure=*lattice or tubular material=steel

Delta tower Tower with a cross-arm supported on a Y-shaped structure. This is usually used on single-circuit lines with voltages pf 230 and 115 kV.
H-frame towers Towers composed of 2 or more poles and a cross-arm. This is used on 115 kV or 69 kV lines which usually use poles with approximate heights of 18 to 20 m.
