Power outages in Paraguay: causes, protection, and solutions

The first power outage is surprising. The second is annoying. After the third, you start to get organized. Power interruptions are part of daily life in Paraguay, with a frequency that varies greatly from one neighborhood to another and from one season to another. It's neither a drama nor an anomaly, but it's a factor that you have to deal with, and which is managed very well once you prepare for it instead of enduring it.

The paradox deserves to be explained, because it's confusing. Paraguay produces almost all of its electricity from hydroelectric power, thanks to two of the most important facilities in the world, Itaipú shared with Brazil and Yacyretá shared with Argentina. The country therefore has a production far exceeding its consumption. The problem is not production but distribution: the network managed by ANDE, the sole public operator, has to serve a rapidly growing agglomeration, with overhead lines exposed to bad weather, vegetation growing into the cables, and transformers heavily strained in summer. Tropical storms and consumption peaks linked to air conditioning do the rest.

This guide covers the nature of outages, the real risks to your appliances and to you, protective equipment classified by level, and the reflexes to adopt. A preliminary warning, because it concerns people's safety and not equipment: the section on generators contains instructions that tolerate no exceptions, and a poorly used device kills people every year around the world who thought they were doing well.

The frequency of outages: what to expect

Types of outages

Type	Duration	Causes and effects
Micro-outages	A few seconds	These are the most frequent and most insidious. Too brief to notice anything other than a flicker, they are enough to restart a router, cut a video conference, stop and restart an air conditioner, reset the oven clock. They result from network fluctuations and load calls, especially when air conditioners start up en masse. Their cumulative effect on compressor and motor appliances is real: repeated restarts and voltage surges shorten the life of the equipment.
Short outages	From a few minutes to one or two hours	These result from local incidents: faulty neighborhood transformer, disconnected cable, branch fallen on a line, damaged pole. This is the most common situation, and technical intervention generally restores power within a reasonable time.
Long outages	From several hours to half a day	Two main causes. First, tropical storms, with strong winds, hail, and fallen trees, which damage lines over long distances and require repairs under difficult conditions. Second, consumption peaks: in the middle of summer, the simultaneous demand from air conditioners puts the network under strain and transformers fail. The austral summer, from December to February, is when these outages are most numerous.
Scheduled outages	Half a day, announced in advance	The operator plans interruptions for network maintenance and reinforcement, announced a few days in advance on its information channels and website. Get into the habit of following these announcements for your area: this is the only type of outage that is entirely predictable, and it would be a shame to discover at nine in the morning that you are cut off until the evening.
Major incidents	More than a day, exceptionally	Unusually large storm or incident on the main network. This is rare, but the impact is considerable, especially in mid-summer without air conditioning. It is this scenario, and this alone, that justifies investing in a generator for a private individual.

Geographical disparities

The frequency of outages varies significantly depending on the area, and it would not be serious to give precise figures by neighborhood: they depend on the condition of the transformer serving you, the density of connections on your line, and the surrounding vegetation, all parameters that change from one street to another. The general trend, however, is stable.

Zone	Situation
Villa Morra, Carmelitas	The best served areas of the capital, with newer equipment and short restoration times. Many new buildings there also have a backup generator supplying common areas and elevators, which significantly changes the experience of an outage.
Las Mercedes, Manorá	Good situation, with transformers shared among fewer households, therefore less exposed to overloads.
Aviadores del Chaco, Santa Teresa	Rapidly growing neighborhoods, where new constructions put a strain on an existing network that has not always been reinforced at the same pace.
Historic Center	Older network, old overhead lines and abundant vegetation near the cables, which lengthens repair times after a windy episode.
Peripheral communes	More frequent and longer outages, with longer restoration times after storms, as these areas are dealt with after priority sectors.
Rural areas and Chaco	Minimal network, very extensive lines, interventions sometimes spread over several days. In these areas, an autonomous backup solution is not a comfort but a condition for installation.

What to remember: as with fiber optics, the choice of neighborhood is the first lever. If your activity depends on a stable power supply, this criterion deserves to be considered before signing a lease, in the same way as the rent. A concrete point to check during visits: does the building have a backup generator, and does it only supply common areas or also the housing units? The answer changes everything, and this is the kind of question that our real estate support systematically asks.

The real risks

For your appliances

The main danger is not the outage itself but the restoration of power. When the power returns, the voltage is unstable and peaks exceeding the nominal value can reach plugged-in appliances. It is these surges, more than the absence of electricity, that destroy equipment.

Appliance	What's at stake
Air conditioners	The compressor is the most exposed and most expensive component. A power surge can destroy it instantly, and repeated restarts wear it out prematurely. An air conditioner here has a significantly shorter lifespan than observed in Europe, and repairing a compressor often exceeds its economic value.
Refrigerator and freezer	Same compressor problem, with the added issue of electronic boards in recent models. Material damage is compounded by the loss of contents.
Computer	The power supply is the first victim, but the real risk lies elsewhere: a sudden shutdown during disk writing can corrupt files or the system. Your backups must be automatic and hosted elsewhere than on the machine, regardless of any electrical issues.
Router and network equipment	Permanently plugged in, they absorb all power surges and are among the most frequently replaced devices. Their failure deprives you of internet until they are replaced, which is problematic if you work remotely.
Appliances with electronics	Washing machine, dishwasher, oven: the control board is the weak point, and its replacement represents a significant portion of the appliance's value.

The calculation is simple: proper protection represents a one-time investment of a few hundred dollars, compared to replacing an air conditioner or refrigerator. The return on investment is achieved with the first appliance saved, and it almost always happens within the first year.

For people

This aspect is systematically overlooked in practical guides, yet it is the most important. A prolonged outage in the middle of summer, without ventilation or air conditioning, causes the indoor temperature to rise very quickly. Infants, young children, the elderly, pregnant women, and people with heart or respiratory conditions are vulnerable to this heat. Regular hydration, the coolest room in the house, closed shutters on the sunny side, wet cloths, lukewarm showers, and monitoring of vulnerable people. If signs of heatstroke appear—confusion, incoherent speech, burning skin with cessation of sweating, malaise—it is a vital emergency: call 911 and cool the person while waiting for help.

Two other safety points. If a household member depends on an electrical medical device—oxygen concentrator, ventilation device, pump—or medication requiring cold storage, the issue of backup power must be discussed with their doctor before moving to the country, and not improvised. Finally, never touch a cable that has fallen to the ground or damaged equipment; keep everyone at a distance, including from puddles around, and report it to the operator: only authorized technicians should intervene, never a private individual.

Protection solutions

Level 1 — Surge protectors

Aspect	Detail
What it is	A power strip with built-in surge protection. It absorbs voltage peaks before they reach the appliance. Be careful of the most common confusion: an ordinary power strip, even a good quality one, offers no protection. Make sure the product explicitly mentions surge protection and an operating indicator.
Where to install them	On each outlet powering an expensive appliance: air conditioner, refrigerator, washing machine, television set and peripherals. For computers and routers, prefer a UPS directly, which performs the same function and more.
What you need to know	A surge protector does not provide any power: it protects against voltage peaks upon power restoration, not against the outage itself. Most importantly, it wears out. Each absorbed surge reduces its capacity, and a used model only offers a false sense of security. In an environment where surges are frequent, plan to replace them every two to three years, and replace them without question after a nearby lightning strike. Many models have an indicator light showing if the protection is still active: check it from time to time.

Level 2 — Uninterruptible Power Supplies (UPS)

Aspect	Detail
What it is	A UPS combines surge protection and a battery. It takes over instantly during an outage, without perceptible interruption. This is the solution for anything that shouldn't shut down abruptly.
For the router	A small dedicated UPS maintains the connection for several hours of outage. This is probably the best value for money in terms of cost and comfort gained from this entire article: your phone and laptop continue to function on their own batteries, and you retain internet access.
For the workstation	A medium-capacity UPS powers the computer, screen, and router long enough to finish a meeting, save, and shut down properly. For remote work, this is basic equipment, not a luxury. Size it according to the actual connected power, keeping a margin: an overloaded UPS will cut off immediately.
For large appliances	There are high-capacity models capable of keeping a refrigerator running for a few hours, but they are bulky, heavy, and expensive. Beyond short outages, the answer is no longer a UPS but a generator or a home battery.
Maintenance and safety	Batteries wear out, faster than in temperate climates due to frequent cycles and heat: expect replacement after a few years, and don't discover the failure the day you need it. Test the autonomy once a year by deliberately unplugging the device. Install the UPS in a ventilated area, never in a closed cupboard or under furniture, and never plug in a heating or motor appliance, as this is not what it is designed for.

Level 3 — Voltage stabilizers

Aspect	Detail
What it is	The network is nominally 220 volts, but the actual voltage fluctuates, with frequent drops during periods of high demand. These undervoltages dim lights, slow down fans, and, most importantly, heat up motors, which compensate by drawing more current. A stabilizer maintains a regular output voltage regardless of input variations.
When it's useful	For motor or compressor appliances: air conditioners, refrigerators, washing machines, pumps. These are the ones that suffer from undervoltages, and they are also the most expensive to replace. In a dwelling located at the end of a line or in a neighborhood prone to variations, a stabilizer dedicated to the air conditioner and another to the refrigerator is a sensible investment.
How to choose	Sizing is based on the appliance's starting power, which is significantly higher than its nominal power for anything with a motor. If in doubt, ask for advice in-store, stating the exact model to be protected, and plan for more rather than just enough.

Level 4 — Generators

Safety rules, above all else. A thermal generator produces carbon monoxide, a colorless and odorless gas that kills without warning. The following instructions are not comfort recommendations, they are conditions of use.

• Never indoors. Not in the dwelling, not in a garage even with the door open, not in a basement, not on a closed balcony, not under an awning, not in a laundry room. A generator must be operated exclusively outdoors, in a clear area, and at a good distance from windows, doors, and ventilation openings, including those of neighbors. No additional ventilation, no fan, no open window makes indoor use acceptable.
• A battery-powered carbon monoxide detector in living and sleeping areas is an inexpensive and relevant precaution when using a combustion appliance.
• Never connect directly to the electrical panel without a source inversion device installed by a professional. Powering the dwelling through an outlet by injecting current into the system sends electricity back to the grid and can electrocute technicians working on the line. This is prohibited and deadly. Appliances connect directly to the generator, using appropriate and well-maintained extension cords.
• Never refuel with the engine running or hot. Stop, let cool, then refuel. Gasoline sprayed onto a hot exhaust can ignite. Store fuel in approved cans, outdoors, away from any heat source, and never in the apartment.
• Protect from rain without enclosing. A wet generator presents an electrical risk, but sheltering it in an enclosed space brings back the risk of poisoning. An open-sided awning, outdoors, is the solution.

Aspect	Detail
When it's justified	A medical dependence on an electrical device. This is a non-negotiable situation that should be discussed with a doctor before installation. A professional activity that cannot tolerate prolonged interruptions, and for which UPS devices are insufficient. A location in a peripheral or rural area, where outages are frequent and restoration is slow. For most expatriates living in central districts, a generator is overkill: UPS devices and surge protectors cover most situations.
Types	Classic portable models are the most affordable and power essential items: refrigerator, lighting, ventilation, computer equipment, and possibly a low-power air conditioner. They are noisy, which poses a real neighborhood problem and is often prohibited by condominium regulations: check this point before buying, not after. Inverter technology models are quieter and deliver cleaner power, better suited for electronics, at a higher price. Finally, fixed installations with automatic start, reserved for homes and businesses, fall into a different budget and require professional installation.
Purchase and Maintenance	Specialized resellers exist in Asunción, and the used market is active; on the latter, the number of operating hours is the determining criterion. For maintenance, change oil and filters according to manufacturer recommendations, use fresh fuel, and a fuel stabilizer if used occasionally. Most importantly, run the device for about twenty minutes once a month: a generator that has been inactive for several months frequently refuses to start on the day it's needed, which is the exact opposite of the intended purpose.

Level 5 — Home Batteries and Solar

Aspect	Detail
Home Batteries	A residential storage battery takes over instantly, without noise, without fuel, and without risk of intoxication, making it the most comfortable and safest solution for a home. Its capacity allows it to last several hours with reasonable use. The obstacle remains the cost, which currently places it in the high-end, although the trend is downward. Seriously consider it for a house, but less often for a rental.
Solar Power	The country benefits from remarkable sunshine, and the photovoltaic potential is real. A significant caveat, however, often overlooked: a grid-connected solar installation automatically shuts down during an outage for the safety of workers. Without a battery and an inverter designed for off-grid operation, panels will therefore provide no power during an outage. If your goal is self-sufficiency and not just savings on your bill, you should aim for a combination of panels and storage, and this point should be explicitly verified with the installer. Also, check the regulatory framework applicable to grid injection, which affects profitability and is evolving.

The Practical Guide During Outages

What to Do

Moment	What to do
When the outage occurs	Unplug sensitive appliances that are not protected: air conditioners, household appliances, computer equipment. It is the restoration of power that is dangerous, and an unplugged appliance is safe. Keep the refrigerator closed. It will keep cold for several hours if not opened, and each opening significantly reduces this autonomy. Always keep some ice packs in the freezer: they extend food preservation and can be used to transfer sensitive foods to a cooler if the outage is prolonged. Identify the cause. Are your neighbors affected? Is public lighting working? If you are the only one affected, check your electrical panel. Otherwise, ask the building manager, ¿se fue la luz en todo el edificio? (Did the power go out in the whole building?), and report it to the operator at the number on your bill or via their app.
During the outage	Conserve your phone battery. It is your light, your means of communication, and your internet access. A constantly charged power bank is one of the most useful accessories in the house; get into the habit of recharging it as soon as it's partially used, not when you need it. Manage the heat. Keep blinds closed on the sunny side, circulate air when the outside temperature drops, hydrate regularly, use damp cloths, and take lukewarm showers. Monitor children, the elderly, and vulnerable individuals, and don't hesitate to take refuge for a few hours in an air-conditioned place, such as a shopping mall or cafe, if the outage is prolonged during hot weather. This is not weakness; it is a smart decision. Illuminate safely. Prefer rechargeable lamps and headlamps to candles. Candles are a common cause of domestic fires during outages, especially with children or pets in the home. If you do use them, never leave them unattended, never near fabrics, and never in a room where someone is sleeping. Be cautious with elevators. In buildings without emergency generators, avoid using them during a thunderstorm: an outage could trap you inside.
When power returns	Wait a few minutes before plugging anything back in: the first moments after power restoration are when voltage is most unstable. Reconnect gradually, appliance by appliance, finishing with air conditioners, which draw a lot of power when starting up. A general and simultaneous restart in an entire neighborhood can sometimes cause the transformer to trip again. Check your food. After a long outage, any refrigerated product that has warmed up, especially meat, fish, prepared meals, and dairy products, must be discarded without hesitation. Food that has thawed should not be refrozen. If in doubt about a product, throw it away: the cost of food poisoning far exceeds that of a pack of meat.

The Outage Kit

Equipment	Priority	Why
Surge protectors for expensive appliances	Essential, from installation	Basic protection, at a negligible cost compared to the protected equipment
Small UPS for router	Essential	Maintains connection during outages, including micro-outages
UPS for workstation	Essential if you work remotely	Prevents sudden shutdown and allows you to finish and save your work
Power bank for phone	Essential	Your phone is your light, your connection, and your access to information
Rechargeable lamps and headlamp	Very useful	Safer and more practical than candles
Ice packs and cooler	Very useful	Extend food preservation during long outages
Portable battery-powered fan	Useful in summer	Significantly improves comfort and limits heat-related risk
Stabilizers for air conditioner and refrigerator	Recommended depending on the neighborhood	Protect motors from recurring undervoltage
Carbon monoxide detector	Essential if using a combustion appliance	Carbon monoxide cannot be smelled or seen
Generator	Optional, depending on the situation	Justified in poorly served areas, for medical dependence, or critical activity

Most of this table, excluding the generator, represents a one-time investment of a few hundred dollars and covers the vast majority of situations. This is little compared to what a single damaged appliance would cost, and it should be purchased in the first few weeks rather than after the first incident.

ANDE: Billing and Reporting

Understanding Your Bill

Aspect	Detail
The Tariff	This is the significant advantage of the situation: thanks to hydroelectricity, electricity is significantly cheaper in Paraguay than in France, at a very favorable rate. The bill for an air-conditioned home remains moderate, with a marked difference between summer, when air conditioning accounts for most consumption, and winter. The type of equipment weighs heavily: air conditioners with inverter technology consume significantly less than older models, which is a point to check when viewing a property.
Payment	Several channels exist: the operator's app, mobile wallets, your banking app once your Paraguayan bank account is open, service payment apps, or physical counters. Online payment avoids queues. A point of vigilance for tenants: upon moving in, check whose name the contract is under and if there are any arrears, as unpaid bills lead to a supply suspension after several months of delay, with restoration fees. Activate due date notifications as soon as the account is opened.
Reporting an Outage	The breakdown number is on your bill and on the operator's website: write it down and save it in your contacts as soon as you move in, rather than looking for it in the dark. The app also allows you to report a fault, and the operator's social channels publish the status of interventions and affected areas during large-scale incidents. Note your report reference: it is useful for follow-ups.

Conclusion

Power outages are part of daily life in Paraguay, with an intensity that varies by neighborhood and a significant worsening during the austral summer. They are due to a distribution network strained beyond its design capacity, in a country that nevertheless produces far more electricity than it consumes. The situation is gradually improving, but it will not disappear in the short term: preparation remains the right response.

Three levels are sufficient for most households. First, the choice of neighborhood, which determines the frequency you will be affected, and which should be decided before signing a lease. Next, protective equipment, surge protectors for expensive appliances and UPS devices for the router and workstation, for a modest budget and immediate benefit. Finally, good habits: unplug during an outage, do not open the refrigerator, wait before replugging, and discard any food that has warmed up without hesitation.

If you are considering a generator, remember the only truly non-negotiable point in this article: it operates outdoors in an open space, never in an enclosed area, never connected directly to the home's electrical system without a professional transfer switch, and never refueled with a hot engine. The rest can be learned in a few weeks.
