Electrical energy in the Philippines, Part 2 – Turbines, AVR’s and Savings

Okay, so right after discussing some of the matters you can proactively place into area in get to offer with electricity irregularities in teh Philippines, let’s take a seem at some other elements.


Countrywide Electrical power Supply

The Philippines tends to make use of regular energy generation (fossil gas-powered stations) and also relies on geothermal and hydroelectric crops.  With the population of the Philippines not long ago hitting 100 million souls and constrained increases of genuine energy production, electrical energy shortages are starting to be a dilemma.  2015 in particular is heading to bring a host of shortages to the Luzon spot, with the federal government there scrambling to source supplemental ability generation to go over the expected shortages.


In get to deal with the restricted vitality supply, a lot of provinces institute planned “brownouts,” rolling them all-around the point out in purchase to provide at minimum some daily ability to impacted lack areas.  Mindanao – which depends heavily on hydroelectric electrical power generation from it’s a lot of raging rivers – is recognized to have every day rolling brownouts through the “dry” summer months when the h2o tables throughout the island fall precipitously.  Photo voltaic manufacturing has been getting traction more than the several years, and business photo voltaic crops are breaking ground in some provinces.  The Philippines can also claim the largest photo voltaic driven shopping mall in the world, with 5,760 panels getting mounted atop the SM Metropolis North EDSA mall outputting 1.5 megawatts.



Backup Electric power Output

A number of industrial/company areas and personal residences have emergency backup generators.  The most fuel effective of these are diesel turbines but some lesser “gennies” only operate on gasoline.  Some of the larger hotels and malls you will see have huge diesel backup generator arrays in buy to make certain continued electrical shipping and delivery to their clientele.

Residential photo voltaic arrays are turning out to be a lot more well-liked as time goes on.  Some folks are putting up simple units to power a one deep cycle battery for a number of lights and a fan.  Some others are placing up greater methods with various battery banking companies that can power the total residence.  We experienced a significant technique in Dauin that mainly powered the overall dwelling – we only experienced to change in excess of to the electrical enterprise all through extended cloudy periods or when we had been functioning the bathroom h2o heater much too usually.  Batteries are nonetheless the weak hyperlink on committed photo voltaic arrays.  With the warmth and humidity of the tropics and even with normal servicing, they even now have to be changed a Whole lot faster than all those in a more temperate climes.  As for price for each kilowatt hour, dwelling photo voltaic generation units are however not perfected enough to get a good return on expenditure, especially in the tropics where you will see about .22 to .35 cents per kilowatt hour.  Still, when much more efficient batteries are place into creation, solar energy will be a full recreation changer.

110V and 220V

The Philippines has a 220 volt electrical grid.  If you have a strictly 100 volt equipment (toaster, blender, etc.), you will need to have a voltage converter in order to use it.  Most – if not all – electrical gizmos (phone chargers, desktop and laptop computer electricity supplies, gaming technique, more recent televisions, and so on.) all have ability materials that quickly switch among 110 and 220.  That reported, MAKE Guaranteed to look at the good print on your unit’s electric power offer to make absolutely sure that it does so!  I introduced more than a ton of devices from the United states, and the subsequent objects are the only things I have difficulties with:


  • My Nintendo Wii is the does not change mechanically among the two voltages and I will need to have a 220v power supply in order to use it.
  • My Nintendo DS Lites also need focused 220V charging units.
  • An outdated electrical heating pad for my aching lower back again only uses 110 volts. I can use the 110 V outlet on my AVR unit if I want to use it.
  • Two 110 volt surge protector/energy strips didn’t get the job done in this article. I plugged them in anyways, enable the surge security device “blow up,” and now basically use them as electrical power strips (connected to my AVR).

“Dirty Electricity”

Voltage….er….irregularities are a real dilemma in the Philippines.  Even with the relatively dependable electrical power that we obtain on Negros Oriental, the voltage levels can change wildly at time.  On Leyte and Mindanao, my fellow authors report that it is even worse.  We individually didn’t notice it till we bought a desktop Laptop.  Yes, the lights would sometimes dim in the house, but at the time we obtained the desktop, it really occur to a head, with the Computer restarting with even the slightest ability fluctuation.  We did not detect this with our laptops as their electric power provides had in-line batteries which would modulate the voltage delivery.  To address the desktop concern, we picked up a reasonably reasonably priced Automated Voltage Regular (AVR) and considering the fact that then – quick of a whole electrical power loss – we haven’t experienced any complications. As a matter of truth,  I know it’s performing as anytime it kicks in, the AVR’s mechanical arms make really the ruckus as they do their work holding the voltage steady.  AVR’s normally have far more than one particular outlet, so I also have our LED Tv set and media participant hooked up to it.  And if I really want to go outdated university, it is even got an outlet for 110 volt appliances!  The AVR we acquired was a minor Sassin SVC-1000 (1000 watt), and it expense us 2,500 pesos.  A very little highly-priced, but it is greater than having your Television set or computer harming electricity spikes.  Total, it’s a terrific financial commitment.

Electrical power Costs

With a pressured program and restricted amenities, electricity charges about twice what it does in the United States, costing – on common – about 10 pesos (or .25 cents USD)  per kilowatt hour.  The cost fluctuates marginally throughout the calendar year dependent on a assortment of environmental and generation factors, but when all is stated and finished, if you are heading to run your digital gadgets like you do in the West, it is likely to expense you.  I know some expats that run their aircon devices all working day and night and are on a regular basis working with a seven to eight thousand peso electric powered expenses.  After listening to about this even prior to moving to the RP, I experienced budgeted $200 USD just for electrical power alone.  Fortunately – owing to some energy financial savings steps that we will examine in the next part – our monthly bill has never ever been that lousy.

Having to pay your electrical monthly bill in the Philippines is very effortless – you can spend them straight at the regional electric enterprise business office or – far better however for a much shorter line –  make your way to a variety of nearby banking institutions that take part in the utilities payment network.  Other than Manila and Cebu, you will obtain on-line utility payment alternatives minimal or non-existent.



Electrical energy Savings Tactics

After the shock of getting your initially electric powered invoice, you will most possible get started employing electricity saving measures.  The Philippines embraced fluorescent lights in lieu of much less productive incandescent extended ahead of the United States did, but shutting them off when not necessary is the to start with action in price personal savings.  The second factor you should really seem at is your air conditioning use.  As stated beforehand,  I am a whole wimp and need to have at least the selection to change on my aircon when the heat and humidity in this article grows to unbearable ranges. Back in the US, if it got to hot, I would basically crank the aircon stage to it is maximum degree (10) and not be concerned way too considerably about the expenses.  Here, even so, I seldom have the level bigger than 4.  This delivers the area down to a quite bearable 78 levels Fahrenheit and boundaries the time the compressor is on which lowers our electrical charges.  How a great deal you talk to?  Perfectly, I’ll notify you – We use aircon about 8-10 hours a working day and together with our other electrical use (desktop and laptop computer pcs, Playstation 3, 46 inch LED Tv, etc) we run about 2,400 pesos a thirty day period (or about $54 USD a month).  Retain in mind that this is with a .5 HP Carrier Optima aircon that is really economical and – in my humble view – was just one of the greatest buys we have made.  It is tiny and only fantastic for a medium-sized bed room, but it is low cost to operate and has still to permit us down.  ?
