Power Grid Status

Most power transmission lines are owned/operated, maintained, expanded, and constructed (for transmission projects since 2009) by the National Grid Corporation of the Philippines, while power generating sites are owned by various companies. The government-owned National Transmission Corporation also involves on the ownership of these lines and other transmission facilities aside from NGCP. 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 feeders operated by distribution utilities, like Meralco (Manila Electric Company), and local electric cooperatives/companies, which may also operate subtransmission 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 subtransmission lines operated by utilities or local electric cooperatives/companies).

National Grid Corporation of the Philippines

operator=National Grid Corporation of the Philippines


The National Grid Corporation of the Philippines (NGCP), a private company given a 50-year concession to operate and expand the Philippine power grid, operates most transmission lines in the Philippines. NGCP-owned transmission lines, with voltages of 69 kV, 115 kV, 138 kV, 230 kV, 350 kV DC, and 500 kV, connects power plants with its substations, and feeds them to utility/cooperative owned substations via sub-transmission lines (69 kV and 115 kV), although the utilities/cooperatives may own their own subtransmission lines, mostly lines once operated by NGCP.

National Transmission Corporation

owner=National Transmission Corporation

operator=National Transmission Corporation


The National Transmission Corporation (TransCo) is a government-owned and controlled corporation that is one of the two owners of transmission facilities (along with NGCP) in the Philippines. It was created in 2001 through the Electric Power Industry Reform Act (RA 9136). It also owns, maintains, and operates the distribution facilities that are located on some of the country's economic or freeport zones and all barangays located within its jurisdiction.

Meralco

operator=Meralco

operator=MERALCO

Meralco also operates a network of transmission lines, called sub-transmission lines, that uses either 115 kV or 69 kV. The sub-transmission lines feed power from large substations mainly operated by the National Grid Corporation of the Philippines to Meralco's distribution substations, which may serve a part of a city or municipality or even a whole city/municipality. Occasionally, sub-transmission lines may feed power from a power plant or link to a substation that serves a large industrial customer.

Guidelines

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=plant. The generators inside would get the power=generator tag.
  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(usually for H-frames and lattice structures) or power=pole(for most structures) and the specific tower or pole 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 cross-arm or on the pole itself. Some utility poles have designs other than the usual cross-arm mounted insulator type, like flag, triangular, or asymmetrical (with insulators mounted on the pole or on an adaptor made from cross-arms typically found on most poles) but they should be tagged with power=pole. Insulators or cross-arms 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.
  5. Tagging a tower with owner=National Transmission Corporation or operator=National Transmission Corporation is optional. If its high voltage sign says "TransCo Property" even though that structure/s is/are part of a project done by NGCP (the purpose for this is because TransCo is still involved on the ownership of transmission facilities) such as towers 255, 256, 266, and 267 of Hermosa-Balintawak transmission line and that line or facility was built when TransCo is still the operator, you may tag them.
  6. If a tower that is made of steel was painted with aluminum paint by NGCP because it lasts for more than 20 years which starts a rusting or decaying stage, you may tag it as colour=aluminum or colour=zinc.

Voltages

Here is a list of some common voltages used in power lines in the Philippines

voltage description Line characteristics
139/240
220
220/440 Typical voltage on secondary distribution lines (split-phase from pole-mounted transformers, or rarely, distribution substations). Primarily used in houses and establishments that do not require three-phase appliances, like small businesses.
  • Triple-wire (two phase wires and one neutral/ground wire), but two wires without a neutral are common in the provinces.
  • Usually twisted insulated cable, but bare wires are also used, mainly in split-phase systems without a neutral installed.
  • Uses small insulators, either one or a set of three.
  • Mounted on poles, mostly under primary distribution lines, but may run on a separate set of poles, especially on residential areas.
220/380 Three-phase secondary distribution voltage, usually used to feed large commercial users.
  • Four wire or three wire (wye/Y or delta ) system, with three phase wires and one neutral/ground wire, or three wires with no neutral.
  • Voltage usually obtained from a pole-mounted transformer bank composed of three single-phase transformers.
  • Line typically serves only one customer, typically commercial users.
220/380/440 Three-phase voltage used for high-leg delta systems. *Voltages are 220/440 volts split-phase for ordinary appliances and lighting, 440 volts three-phase for larger appliances, and 380 volt high-leg voltage.
  • Transformers used can be two, one with two secondary wires (one links to one phase wire from the second transformer), and another carrying three secondary wires (one is a center tap)and larger than the other, or a single-phase transformer with four secondary wires (one is a center tap linked to a neutral wire), usually arranged in groups of three, forming a transformer bank.
3625/6280 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 6.28 kV systems being reconnected to the 34.5 kV system, 6.28 kV lines below 34.5 kV lines discarded, or 6.28 kV-only lines replaced by 34.5 kV lines), but still exist on parts of Manila, Pasay, Quezon City, and Parañaque. Transformers of 3.625/6.28 kV lines are distinguishable from those in 34.5 kV lines by having bushings on the side rather than on the top.
7970/13800 (sometimes 7620/13200) Standard three-phase distribution line voltage by many electric cooperatives, but also used by Meralco in certain areas (i.e. northern Bulacan, southern Cavite, part of central Laguna, and Batangas City - San Pascual area). May be found under a 69 kV subtransmission line as a feeder.
  • Uses one or two-shed pin insulators, but typically uses one-shed insulators
  • Transformers found on the line usually has two bushings, but only accommodates one phase.
20000/34500 Standard distribution voltage used by Meralco, but also used by Cagayan Electric Power and Light Company (CEPALCO) in some lines in Cagayan de Oro.
  • Can be either two-phase or three-phase
  • Usually overhead power lines, but may be an underground or overhead cable.
  • Almost placed roadside, with some exceptions
69000 Typical subtransmission line voltage by NGCP and many provincial electric cooperatives. Also used by Meralco on subtransmission line in Bulacan and Batangas City and the Meralco-owned Clark Electric Distribution Company (CEDC) serving Clark Freeport.
  • Usually mounted on single poles, usually with two cross-arms with insulators forming an asymmetric arrangement or an "armless" design, where the insulators are mounted on the pole instead on a cross-arm, but H-frame towers, with two or three poles and a cross-arm, and rarely, lattice towers (used on one 69 kV line in Isabela and another in Pampanga) and tubular steel poles (like on a 69,000 line that leads to Samal, Bataan) are also used. NGCP usually uses both poles with cross-arms and poles with insulators mounted on them directly, but electric cooperatives/utilities and Meralco primarily uses armless poles (Meralco's subtransmission line linking its two substations in Batangas City with the JG Summit chemical plant in Simlong, however, uses both designs, with and without cross-arms, like some NGCP subtransmission line that parallel some of its segments).
  • Uses hanging insulators, mounted on the cross-arm placed on the pole, or pin insulators mounted on the pole itself.
  • Lines may link to large industrial users fed directly to the subtransmission grid.
115000 Standard subtransmission voltage by Meralco, especially on Metro Manila, Laguna, Cavite, Rizal and most of Bulacan. Used also by NGCP on some subtransmission lines in Cavite and transmission lines in Ilocos Region. *Usually mounted on insulators on single poles, either wood,concrete, or steel and with or without cross-arms, but H-frame towers or lattice towers are also used.
  • May feed a large industrial customer connected to the subtransmission grid.
  • Cables are usually single-conductor, but double-bundle cable are also used.
138000 Typical voltage of NGCP transmission lines in Visayas and Mindanao.
230000 Typical voltage of NGCP transmission line in Luzon. *Usually supported by lattice towers, but can also be used on tubular steel poles (i.e. Hermosa-Balintawak, Limay-PPDC, SMC Consolidated Power Plant-Limay, Bay-Biñan, Mexico-Hermosa, Biñan-Muntinlupa, Limay-Hermosa, Limay-GNPower, Hermosa-San Jose, etc.)
