Prepare for a Cold Snowy Winter with Standby Generator Rebates

Two vehicles, barely visible and buried in snow after winter storm Nemo.

As kids head back to school, thoughts turn to the coming winter. The winter of 2014 brought unusually severe ice storms along with record snowfalls across the South that stranded motorists and cut power to hundreds of thousands of utility customers. The National Guard opened their armories to keep some residents warm, while others sheltered in malls and Red Cross facilities.

Meanwhile, the Midwest and East battled record snowfalls that came one after another. People struggled to keep their driveways and walks clear while power companies worked to keep the power on. Heavy snow made accessing substations and other utility facilities difficult and interfered with efforts to restore power.

Cold – Snowy Winter Predicted

Clogged Streets After a Winter Snow and Ice Storm

The Winter of 2015 is promising cold and snow for much of the country. The Farmers Almanac, well known for its average 80-percent-correct long-range forecast is predicting a cold and snowy winter for the northern tier of the country, and colder than average temperatures across most of the South. Some portions of the country may see slightly warmer temperatures, but more precipitation than usual.

Lessons learned from last winter include staying off the roads during and after an ice storm. Don’t abandon your vehicle if you become stuck, and hire someone to shovel your snow if doing so is too strenuous. A number of people died or were seriously injured after leaving their stranded cars, and the frequent, heavy snows contributed to heart attacks across the country.

No less important is to prepare your home for winter, and a source of backup emergency power is just one way to keep your home safe and warm during a winter storm. A standby generator can keep the lights on and the furnace running. Without one, you may find yourself seeking shelter someplace else while you worry about frozen pipes that may burst and flood your home.

Take Advantage of Rebates

While back-to-school sales are not necessarily associated with standby generators, manufacturers like Kohler offer rebates and referral bonuses. Now through the end of September, Kohler offers a $150 rebate on the purchase of a new 8.5 to 150 kilowatt standby generator. The generator must be purchased between August 1 and September 30 of 2014 and faxed or emailed requests sent by October 15, 2014, and mailed requests postmarked by the same date.

Kohler also offers a referral rebate when you buy a standby generator. Refer a friend, family member, or neighbor, and you can receive a rebate of 75 dollars. This offer is good until the end of 2014 and requests must be postmarked, emailed, or faxed by January 15, 2015.

It is not all that hard to imagine that the coming winter will be any less brutal than last year. Put together an emergency kit for your car in the event that you become stranded. A good emergency kit starts with blankets, candles, flashlights, chocolate bars and protein bars, and matches. Several candles can raise the interior temperature of a car by 20 degrees. Always carry water in your car.

If your home and family is not protected by a standby generator, now is the time to purchase and install.

Before winter arrives, service your standby generator and keep it ready. Follow the manufacturer’s maintenance schedule and stock several maintenance kits for use during long-term outages. When a storm hits, keep the generator clear of snow and maintain a path to the unit for easy access.

A standby generator offers peace of mind by keeping your family and home safe during power outages caused by storms, accidents, and equipment malfunctions. Don’t you think it’s time your family was protected?

Generator Noise Levels – How Loud Are They

Automatic Home Standby Generators

Automatic Home Standby Generators

Generators make a positive impact on our lives by providing power when we need it, and where we need it. When the electric utility supply is interrupted, we can rely on standby generators to fill in the gap until the utility power is restored. They keep our homes cool, our food safe, and prevent the basement from flooding while providing light and entertainment.

On job sites, at sporting events, and while camping in the wilderness or traveling in an RV, generators supply electric power for a wide variety of needs and conveniences that range from refrigerators and air conditioners to coffee makers and strings of festive camping lights.

Noise associated with a internal combustion engine can be bothersome, if it is too loud or too close. Many communities have noise regulations and they apply to air conditioning units and standby generators alike, as well as other noise producing machines. Campgrounds also enforce rules designed to reduce noise pollution, and even if your generator is quiet, turning it off at night is polite and friendly.

Noise Measurements

The ‘bel’ is named in honor of Alexander Graham Bell, but the unit of measure is rarely used. Instead, we measure sound using the ‘decibel’ which is one-tenth of one ‘bel’. For comparison purposes, the base level that most sounds are compared to is 70 decibels.

Consider these everyday sound levels:

  • Passenger car going 65 MPH heard at 25 feet – 77dB.
  • Music in a living room – 76dB.
  • Vacuum cleaner – 70dB
  • Central Air Conditioner at 20 feet – 68dB

70dB is twice as loud as 60dB which is considered fairly quiet, and four times as loud as 50dB which is very quiet. Office or restaurant conversation weighs in at 60dB, and quiet conversation at home at about 50dB.

Moving the other direction, we have a garbage disposal at 80dB, an electric blender at 88dB, a jack hammer at 100dB, and front row seats at a rock concert at 110dB, which is painful to many people and can cause serious, long-term damage.

Levels from 80 to 100dB can cause damage after eight hours of exposure, and each increase in sound level increases the likelihood and severity of damage.

Generators and Noise

Residential Standby Generators meet Noise Restriction Requirements

The good news is that generators designed for use in residential areas comply with noise levels that allow you to keep your sanity and won’t anger the neighbors if they have their windows open.

Many central air conditioners are rated at about 68dB when heard from 20 feet away. The Generac Guardian line produces just 66dB at 23 feet. Kohler Power Systems and Briggs & Stratton are slightly louder at 69dB for their 20 kilowatt units, and Cummins Power Generation weighs in with just 62db – not much more than conversation in a restaurant.

RVs provide a home for traveling at any time of the year.

If you’re planning to go camping or RVing, it’s good to know that your generator won’t bother nearby campers. Inverter models are very quiet. The Generac iX 2000 produces an estimated sound level of 63dB while the Westinghouse WH1000i comes in at about 59dB – easy enough to stand next to and hold a conversation without trying to talk over the generator.

Even Commercial Models like the Generac Quiet Source are noise friendly with ratings from 65 to 68dB—quieter than many commercial air conditioning units.

Facts About Portable Generator to House Connections

A generator connected to a house with a dedicated cable and inlet box.

Connect Portable Generators with a Dedicated Cable and Inlet Box to a Manual Transfer Switch

When a power outage occurs, there is no doubt that the best way to provide backup emergency power to a home is with standby generator system. An automatic transfer switch controls the home’s source of power and switches it between the utility supply and the standby generator supply as required. It happens automatically and the generator runs on municipal natural gas or LP gas from a residential storage tank.

In cases where a standby generator is not practical or can’t be installed for some reason, a portable generator can supply power during an outage.

Portable Connection Options

A Generator Connected Through an Inlet Box to a Manual Transfer Switch.

Connecting appliances to a portable generator with extension cords is the most basic option. The cords plug into the generator’s receptacle panel and then connect inside the house to the required appliances. This works fine for appliances such as refrigerators and freezers, or a sump pump that is keeping the basement dry during a storm. However, permanently wired appliances won’t receive power this way, and that includes furnaces, central air conditioners, electric ranges, and well pumps.

A manual transfer switch can supply essential circuits with electricity. Electricity is distributed through circuit breakers in a dedicated panel that is controlled by the switch. During an outage, electricity is supplied by a portable generator through a dedicated cable that connects the generator to an inlet box which supplies power to the switch.

Safe Emergency Power

Pre-wired 30-Amp Manual Transfer Switch Kit Including Switch, Dedicated Cable, and Inlet box

The reason for a transfer switch is simple. A manual or automatic transfer switch isolates the home from the utility lines when power is supplied by the generator. Without a transfer switch, it is quite possible to accidentally feed the utility lines with a generator. The transformer that supplies the house will convert that generator power from 240 volts to as much as 69,000 volts.

More than enough voltage to kill or seriously injure a utility worker.

If you accidentally backfeed a utility line with your generator and your actions cause injury or death to a utility worker, you will be held responsible for those actions. Never backfeed your home and you won’t accidentally backfeed the utility lines.

Manual Transfer Switches

A manual transfer switch is exactly what its name states. It is a manual device that requires a human to throw the switch from utility to generator. When that happens, the circuits supplied by the generator are isolated from the utility lines and connected to the generator lines. Returning the switch to the utility reverses the action and reconnects utility power.

When a power outage occurs, the homeowner moves the portable outside to a predetermined location that won’t gather standing water or allows deadly exhaust  to enter the home. The dedicated power cable is plugged into the generator panel and into the inlet box. After starting the generator and allowing it to warm up, the generator’s main breaker is turned to on, and then the manual transfer switch is moved to the generator position.

Power is now supplied to the circuits connected to the manual transfer switch.

When the utility restores power, the process is reversed. The manual transfer switch is returned to utility mode to restore power to the home. The main breaker is turned off, which removes power from the cable and receptacle panel. Finally, the generator is turned off, allowed to cool, and put away.

Extension Cord Size

Only use outdoor extension cords with the correct gauge wire. Size extension cords based on the current that the generator receptacle is capable of supplying. If a receptacle has a 20-amp circuit breaker, then it could supply 20 amps of current, and a 12-gauge extension cord is the minimum size.

A common mistake is to size the cord by the appliance requirement. For instance, using a 16-gauge extension cord to run a 10-amp appliance off a 20-ampere generator receptacle. If someone plugs another appliance into the cord, the cord could overheat and cause a fire.

Keep extension cords on hand that will supply the maximum amount of current that might be drawn through the cord. Don’t rely on guesses or that no one will make a mistake.

Dedicated Cables

Dedicated cables connect a 240/120-volt generator outlet to the inlet box. Distributor or manufacturer supplied cables have the correct connectors for the amount of current they can handle. A 30-amp cord has connectors rated at 30 amps, and will only connect to 30-amp receptacles. The same is true of 50-amp cables.

The cables have four wires configured in similar way to an electric dryer or electric range cable. Two wires each carry 120 volts for a total of 240 volts. Another wire serves as a neutral or return for the 120-volt wires. The fourth wire a ground and connects to the generator’s metal chassis and to the ground bus in the manual transfer switch.

Tips for Choosing the Right Portable Generator

Generac Portable XG Series XG8000E Electric Start

Portable Generators Provide Power When and Where You Need it.

Portable generators make a lot of sense when you need power where there is none available. Job sites without utility service, campgrounds that lack electrical hookups, picnics, tailgating, and anywhere else that can’t be reasonably reached with an extension cord.

Fortunately, portable generators are available with capacities that range from less than 1000 watts to more than 15,000 watts. Whether you need a little power at a campsite or a lot of power on the job, there are portable generators designed to fit nearly every need.

Power Quality

A sine wave illustrating how current direction changes 60 times per second in AC current..

A clean AC electrical signal at the proper frequency and voltage provides the best power.

Portables can produce good quality power, but many do not, and that is especially true in the off-brand market where manufacturers save money by using low-tech speed governors and alternators, or inadequately sized motors.

The A-C signal should have a frequency of 60 hertz with a sinusoidal waveform, but as load increases, frequency drops as the motor slows and then current increases as the voltage drops with the frequency. The distorted power characteristics can play havoc with electronics and may damage motors.

Engine Safeguards

Generators are often used for extended periods of time. It’s not uncommon to start a job-site portable at the beginning of the work day and keep it running all day long. At the campground, operating a small refrigerator will require a generator that can run all day and into the night.

The Westinghouse WH1000i

Inverter Generators are Quiet and Fuel Efficient

One very important safeguard for engines is a low-oil shutoff feature. If oil levels drop to a level that could cause engine damage, the generator will shut down automatically before damage occurs.

Another safeguard that isn’t as obvious is an adequately sized engine. When generators run at their maximum specified power, an engine that is barely able to keep up won’t take additional load easily and wear increases dramatically. A better generator will have an engine that provides an adequate margin of power for the generator’s continuous load rating.

Backup Power

Standby Generators are a Better Choice for Emergency Home Backup Power

Planning to buy a portable generator for use when the power goes out? Think carefully before you go ahead. Some manufacturers advertise their products for use during a power outage, but a portable generator may not be the best choice.

Unlike standby generators, portables are not automatic and they tend to be noisier and have shorter maintenance periods. They don’t start automatically and won’t run if you are not home to hook them up, start them, and keep them running with a continuous supply of fuel. If you can’t install a standby unit, a portable may help out—if you’ve properly prepared your home in advance.

The best connection is provided through a manual transfer switch and inlet box. The generator connects to the inlet receptacle with a heavy-duty cable from the manufacturer. The transfer switch isolates your home from the utility lines and powers a limited number of circuits from the generator.

A second option is to use outdoor-rated, heavy duty extension cords. These allow you to power individual appliances, but furnaces and other hard-wired appliances won’t have power.

Important Safety Note: Never backfeed your home through an appliance outlet. Online forums and blogs may say it is okay, but it is a potentially deadly practice that can kill utility workers or unsuspecting neighbors. Always connect the home with a manual transfer switch and a correctly sized cable.

Load Capacity

Wherever you plan to use your generator, choose one that will supply enough power for all your loads and provide a margin that prevents accidental overloading. Total the power requirements in watts for each load, then add the highest surge load to the total.

Briggs & Stratton Elite 7000 Watt Electric Start Portable Generator

Briggs & Stratton Elite Series products have heavy-duty components and features for long-lasting durability. They perform tirelessly around the home, farm or on the job.

Surge is the additional power a motor or other inductive loads require to start. Many motors use triple their running power as they start. A refrigerator that normally uses 900 watts will require 2700 watts for a second or two when the compressor motor starts.

If the power in watts is not provided for an appliance, calculate it by multiplying volts by amps. Amps should be provided on an appliance nameplate. In some cases, power is expressed as V-A, which roughly translates to watts.

A five-amp appliance that runs on 120 volts uses 120V x 5A = 600 watts.

Some generator brands list their models by surge load rather than continuous load. Compare these two models. Although they appear similar, one provides much more power than the other.

  • Company A offers the M-3500 with 4200 watts of surge power and 3500 watts continuous power.
  • Company B offers the S-3700 with 3700 watts of surge power and 2900 watts of continuous power.

Selecting a good portable generator that fits your purpose and your power requirements will ensure your investment provides long-lasting service and electrical power when and where you need it.

Active Tropics Heat Up with Five Tropical Cyclones

As of this date, August 04, 2014, the ocean tropics are very active with five named storms.

Five tropical cyclones shown in the ocean tropics including Bertha, Iselle, Julio, Genevieve, and Halong.

Five Active Tropical Cyclones in the Ocean Tropics

East Coast

Bertha has been downgraded from a hurricane to a tropical storm. It is the second named storm of the Atlantic Hurricane Season and located several hundred miles east of North Carolina. Rapid weakening is expected over the next 48 hours as it moves north before turning east, likely as a post-tropical storm. Bertha’s main effect on the USA will be Rip Currents and high surf.

Rip currents are dangerous and may sweep a swimmer far offshore in a matter of minutes. If caught in a rip current, escape the current by swimming across (parallel to the shore) instead of against it. Most swimmers cannot swim against the current and will tire without making significant progress. Swimming parallel to the shore and away from the current makes it much easier to escape the effects.

Hawaii

Two storms will affect Hawaii later this week. Hurricane Iselle reached wind speeds of 140 mph as a Category 4 hurricane. It will make landfall on the Big Island of Hawaii late Thursday or early Friday as either a weak category 1 hurricane or a strong tropical storm. It will affect the smaller islands with tropical force winds, heavy rains, and high surf.

Approximately two and half days behind Iselle is Tropical Storm Julio which is gradually strengthening. Julio will probably reach hurricane status sometime in the next 48 hours and will probably retain its strength through the weekend. Current estimates have Julio sweeping the northeast coast of the Hawaii islands about 90 miles offshore on Sunday and Monday if it stays on its present course.

TD Genevieve and Typhoon Halong

Tropical Depression Genevieve in the Pacific Ocean presently has 35 mph winds as it moves northwest over the Pacific Ocean. It is expected to strengthen to a tropical storm on Tuesday, and become a category one hurricane by Saturday as it passes north of the Marshall Islands.

Typhoon Halong is a category four storm with wind speeds of 132 mph and is producing waves nearly forty feet high. The storm will retain hurricane strength for at least four days as it turns north toward Japan.

Forecast

The Atlantic Hurricane Season Forecast has been reaffirmed as a below average year according to studies by the NOAA and the Department of Atmospheric Science at the University of Colorado. Cooler than normal ocean temperatures, strong high-level wind shear, dry dusty air from the Sahara Desert, and higher than normal air pressure at sea level over the Atlantic will prevent the formation of many tropical cyclones late this summer and into the fall season.

Thus far, the only named storms have been Arthur and now Bertha. Arthur passed over the Outer Banks of North Carolina and Bertha will miss the coast entirely. If the 2014 prediction is correct, only three to four more named storms are expected before November 30.

The Eastern and Central Pacific Ocean will remain very active for the remainder of the season. Another low pressure system located off the coast of Mexico has a medium chance of forming another tropical cyclone within the next five days.

Preparation

Residents of Hawaii should stay informed by monitoring broadcasts by National Weather Service and local authorities and by following instructions. The NWS Central Pacific Hurricane Center has a detailed list of preparation instructions for residents.

Despite a below normal season, Gulf Coast and East Coast residents should remain prepared with planned evacuation routes in the event a hurricane threatens land. Service standby generators and keep maintenance supplies on hand to keep them running for extended periods. Have a ready bag of emergency supplies. Store potable water—one gallon per person, per day—for a week or more and non-perishable foods including canned meats and vegetables.

Portable generator owners should perform maintenance, rotate fuel supplies and keep them fresh with fuel stabilizers.

An NOAA weather radio can provide alerts 24 hours a day, seven days a week to keep you informed of approaching bad weather.

Stay prepared. A hurricane or tropical storm can strike within days of forming. A less active than normal season still offers a good chance that a hurricane or tropical storm will reach land this year. Don’t be caught unprepared.

Basics of Home Generators for Emergency Backup Power

An infographic showing various severe weather types that impacted the USA during 2012.

2012 U.S.A. History of Extreme Weather

Events in recent years have punctuated the fragility of our nation’s power grid. Hurricane seasons over this year and last have been relatively quiet, but tornadoes, ice storms and other weather-related events have done their share to knocked out power.

There are always equipment failures and accidents, and with every outage comes the possibility of days without electrical power.

Trying to find emergency power during an outage is difficult. Home centers quickly sell out their inventory of portable generators and standby units take time, permits, and electricians to complete the installation.

Backup Options

Mobile Link with Generac Guardian Standby Generator

The best option for homes and businesses are standby generators. They work with an automatic transfer switch to detect power outages and switch on automatically to supply electrical power when the utility cannot.

When the electric utility restores power, they turn off and switch back to the utility supply. Most residential and commercial standby generators operate on natural gas or propane which eliminates frequent refueling. Since they are fully automatic, they work whether you are at home or away on vacation.

Generac XG Series Portable Generator

8000 Watts of Portable Electric Power.

Portable generators can also supply emergency power, but they do not operate automatically. Typical operation involves starting the generator and connecting appliances with extension cords.

A better way is a manual transfer switch with an inlet box, which allows powering of furnaces and other permanently connected appliances. Portable generators usually run on gasoline and require regular refueling.

Maintenance

Maintenance kits offer items necessary to perform complete routine maintenance.

Maintenance Kits Keep your Generator Running.

Generators can run for extended periods of time. Just like a car needs maintenance, so does a generator. Check the oil with every fueling on portable generators and every 24 to 48 hours for standby generators. Top off the oil but do not overfill. Don’t forget to check the coolant level on liquid-cooled models and fill as necessary.

Oil and filter changes are required every four to six days (100 hours is typical) for portable generators and every eight to ten days (200 hours is typical) for standby models. Spark plugs change intervals run approximately every 400 hours of operation.

It is a good idea to keep a three week supply of maintenance items on hand for use during extended outages. With proper maintenance, a generator will offer years of service and thousands of hours of run time.

Power Capacity

A power outage can leave you with this for your only source of light and warmth.

Many homeowners will opt for a unit that delivers power for essential needs. Refrigerator, freezer, pumps, furnaces, and a few lighting circuits. The amount of power required for those items determines the size of the generator. Businesses often have fewer options for standby power and will usually select a unit that not only keeps essentials operating, but also keeps their doors open.

Fuel use is directly related to power consumption. Base consumption begins with the fuel required to start and run the engine, and then increases with the electrical load. The less power used, the less fuel is consumed.

Standby units begin at about 7 kilowatts and run up to 22 kilowatts for air-cooled machines. Liquid cooled units can supply from 20 kilowatts to 150 kilowatts or more. Conduct a power audit to determine the amount of power required.

Installation

Home Standby Maintenance

Home Standby Maintenance

Unless you have considerable experience as an amateur electrician, you’ll want to hire a licensed professional to install a standby generator or a manual transfer switch. Standby generators also require plumbing for the gas lines, and you’ll need to check with the gas company to make sure the line and meter can supply the correct gas pressure and volume.

Some portable units require changes for grounding when connected to a home. Be sure to check the owners manual and provide for proper grounding. Knowing how to do it in advance will save fumbling in the dark and pouring rain with flashlight.
Don’t forget that electrical and plumbing work requires building permits and inspections.

Fuel Storage

Standby units run on either LP or Natural gas. LP gas is stored in tanks while natural gas is supplied through municipal gas lines. LP users will want to make sure they have enough storage to run the generator and home appliances for days.

Portable generators that run on liquid fuel such as gasoline present a problem. Fuel ages and must be rotated on a regular basis. Storing gasoline in regular containers is restricted by many communities. Home owner insurance can also impose restrictions in some cases. Check with local authorities before storing large quantities of fuel.

Plan now and the next power outage won’t leave you in the dark.

Use Standby Generators for Independence and Home Safety

Transmission tower supporting high-voltage electrical transmission cables.

The Nations Power Grid Supplies Electricity to Homes Throughout the Country

Power outages happen for many reasons. Severe weather is the number one cause and weather-related outages often affect large areas. Every year, millions of Americans make-do without electrical power for extended periods after a strong or severe storm knocks out power for days and sometimes for weeks. Many are forced to leave their homes when cold or extreme heat makes their homes unlivable.

But weather is not the only reason for power outages. Equipment malfunctions, accidents, and wildlife are other common denominators in many outages. The aging infrastructure of the nation’s power grid is responsible for widespread outages every year.

What would happen if your power went out for a week? Chances are you and your family would have to seek shelter elsewhere at a hotel or with a relative.

A standby generator offers independence when the power goes out and your home remains safe and comfortable.

Power Outage

We have come to rely on electrical power to a great extent, and our homes are designed to use it. Many systems in homes won’t work without it, and long term outages can inflict damage that costs thousands of dollars to repair. Often, ordinary homeowners insurance won’t cover the repairs or only part of it.

Sump pumps are quite common in modern homes. Rain soaks into the ground near the foundation and is directed to a sump pit through a drainage pipe. The pump switch turns the pump on and empties the pit outside, away from the home. Without power, the pit can fill up and overflow to flood the basement. Damage includes excessive mold, water damage to carpet, finished walls and furniture, and damage to appliances such as water heaters, furnaces, and washers and dryers.

Most heating and cooling systems don’t work. Furnace fans require electricity to distribute or remove heat. Hot water heating systems require electric pumps to make them work, and central air conditioners are known for their high electric power consumption. In sub-freezing weather, water pipes can freeze and burst. Once the power returns, the home floods unless the water is shut off before hand.

A refrigerator can keep food cold in normal conditions for about half a day. Add ice and you can extend that period indefinitely, but where do you buy ice during a power outage? Frozen food will stay frozen about a day, but after that it begins to thaw and becomes unsafe.

Standby Generators

Automatic Home Standby Generators

Automatic Home Standby Generators

A standby generator works automatically and is permanently connected to the home. An automatic transfer switch controls the source of electricity that the home uses. In normal circumstances, the switch feeds the home with power from the electric utility.

When the power goes out, the standby generator system senses the outage immediately and begins a sequence of actions to switch the home to standby generator power. After a short wait to ensure the outage was not momentary, the generator automatically starts and reaches operating speed in a few seconds. The transfer switch isolates the home from the incoming utility lines and connects the generator supply to the homes electrical system.

Most standby systems operate on municipal natural gas or the home’s propane gas tank. Natural gas offers a virtually endless supply of fuel, while an average-sized propane tank will keep the generator running for days. In contrast, most portable generators require frequent refueling with gasoline that may be in short supply during a power outage.

Independence

Standby generators are often packaged with an ATS that includes power management to control appliances that draw large amounts of power.

Standby generators supply homes with power when the utility cannot.

The first thing most people do when the power goes out is call the electric utility to report the outage. Later they call back to find out when the utility will restore power. As the heat inside the home builds or the temperature plummets, homeowners look for other ways to stay comfortable. Such conditions are an inconvenience for many people, but for the elderly or those who rely on medical equipment, power outages can be life threatening.

The standby generator changes that because in less than a minute, the home has power again and the inhabitants are kept comfortable and safe because the home’s essential systems are still operating.

When the homes around the neighborhood are lit by candles and battery operated lanterns, the home with the standby generator has lights, cold food and drink, and a homeowner that isn’t worried about a flooded basement or spoiled food.

A standby generator isn’t something that gets everyday use like a furnace or air conditioner, but when the power goes out, it keeps people in their homes instead of looking for shelter.

How Our Emergency Storm Preparation Plan was Put into Action

An approaching storm with dark clouds and a squall line.

Stay Alert when Severe Weather Threatens and Be Ready with an Emergency Plan

The opportunity to test our emergency storm plan came less than two weeks ago. Tornadoes are not common in our area, but they do occur and the siren going off at 2:30 AM demanded action.

Earlier, a severe thunderstorm watch had been issued and then came the tornado watch. As the large storms moved toward us, the thunderstorm warning was issued complete with hail, damaging winds, torrential rain, and frequent cloud-to-ground lightning.

I was awake at 2:30 in the morning to keep an eye on the weather when the sirens began to sound.

My first action was to wake my wife, grab the dog and the phone, and head for the basement bathroom. She called her mother and her sister to make sure they heard the sirens. Outside, we could hear the wind howling around the house and through the trees. Was it a tornado or very strong wind?

We didn’t know.

And then the power went out.

Emergency Kit

A power outage in a wind storm is never a good thing. You don’t know how long it will take to come back on. A wind storm in 2011 destroyed our neighborhood power lines and power was out for more than a week in 100-degree heat with high humidity.

A blue plastic tub filled with emergency supplies including food, water, first aid kit, and numerous other items.

Keep a Portable Emergency Kit Stocked and Ready
(image via Ready.gov)

Good thing I’ve kept an emergency kit stocked and ready for more than 30 years. It contains most of the usual things you’d expect and a few you might not. There is a battery operated florescent lantern, two flashlights (recently upgraded to LED type), batteries, candles, strike anywhere kitchen matches (in a zipper bag) BBQ lighter, space blankets, disposable ponchos, plastic tarp, water purification tablets, soap, crayons (they never dry out), and portable radio. Tools include a hatchet, belt knife, and multi-tool among other things.

Up until about 20 years ago the kit was maintained in an old Boy Scout knapsack. Today we keep it in a five-gallon bucket from the home center with a lid. It’s very portable—just grab and run. You can sit on it and if you need to, it holds five gallons of water.

Essential Power

Generac Portable Generator Connected to a home via a dedicated cable.

A Portable Generator can Supply Essential Power During an Outage.

The portable generator kept in our garage is not quite as convenient as a standby generator. Standby systems are fully automatic, operate on natural gas or propane, and start automatically whenever the power goes out. They work with an automatic transfer switch, and there just isn’t a more reliable source of emergency backup power available.

Unlike the portable generator, they don’t require you to venture outside when the rain is coming down in buckets, the wind is blowing 80 miles per hour, and the tornado sirens are blaring.

The only item that needed immediate power was the sump pump and we have a backup that runs from a battery for up to seven hours. I wasn’t too worried about the generator yet. There was plenty of fuel if the power stayed out and we had the lantern, candles, and flashlights. Once we had two candles lit—the tall kind enclosed in glass—we turned the lantern off to save the batteries.

Disaster

If disaster had actually struck, we had two cell phones and a land line phone near the basement bathroom door. When trees fall on power lines however, telephone lines are often broken at the same time. Having two distinct ways to call for help is a good idea; one serves as a backup to the other.

The sirens shut off ten minutes later and the wind died down to a mere gale. When the rain lightened, I went outside to assess the damage and connect the portable generator. I keep it maintained so it is always ready. Put it on the driveway and fill with fuel. Plug it into the inlet box and start it up. After a minute to warm up, I turn on the breaker and the set the manual transfer switch.

We had essential power for lights, the fridge, sump pump, and furnace and A/C.

Twenty minutes later, I went back outside and disconnected everything because the power came back on—another reason to upgrade to standby power. It was a relief since the power company had only told us they were still assessing the outage. The outage was probably caused by tree branches hitting the distribution lines and a breaker tripped to isolate the problem.

Two tornadoes were spotted. One by a trained spotter and the other by an actual professional storm chaser. Neither funnel touched down, but the closest persisted for about 10 minutes.

It wasn’t much of a disaster, but it was an emergency and we were ready. I’m going to add an NOAA weather radio to our kit which can provide weather alerts specific to our area. A radio like that could have informed us that the wind outside was just wind and not a tornado.

Being ready with an emergency kit, an action plan, and an emergency source of power made the situation less dramatic. In an emergency, that is important because it helps you focus and remain calm.

Are you ready?

Guardian 22kW Largest Most Efficient Air-Cooled Standby Generator

22kW Guardian Standby Generator shown with Generac's Smart Switch ATS

Guardian 22kW with Smart Switch ATS

Generac’s newest addition to the Guardian product lineup is the largest capacity air-cooled standby generator on the market. No other generator manufacturer currently offers a comparable air-cooled standby unit. The generator supplies up to 22 kilowatts of power while running on LP gas and 19.5 kilowatts on natural gas while using less fuel than similar units with a smaller capacity.

Fuel Efficiency

A glance at the specification sheet for the 22kW, which provides a side-by-side comparison of Generac’s 16, 20, and 22 kilowatt Guardian generators, shows the 22kW uses less natural gas at either half load or full load than either the 20 kW or the 16kW and still generates more power. LP consumption is just slightly higher than the 16 and 20 kilowatt models at half load, and less than the 20 kilowatt at full load, but the fuel used per kilowatt of electricity produced is much lower for both fuels under any load condition.

Chart comparing the fuel use of 16, 20, and 22kW Guardian units showing better efficiency of the 22kW- producing more kw on less fuel.

The 22 Kilowatt Guardian produces more power on less fuel.

Generac points to three design changes that improved efficiency. A better fuel delivery system, engine modifications, and the use of low-loss steel in the unit’s alternator—the component that generates electricity. Low-loss steel is an alloy that reduces electrical losses and improves the efficiency of motors, generators, and transformers.

 22 Kilowatt Models

Norwall Power Systems offers the 22kW in two packages:

The Smart Switch included with the 6551 is an automatic transfer switch (RTSY200A3) rated for use as a 200-amp service entrance and equipped for whole house managed power.

New to the 22 kilowatt models is a reduced exercise cycle of just five minutes, programmable to run on a weekly, bi-weekly, or monthly schedule.

Using Digital Power Management technology, the Smart Switch ATS can manage two central air conditioners without additional hardware. Adding a PMM starter kit and Power Management Modules allows the switch to manage up to four additional high-voltage, high-current loads such as an electric hot water heater, well pump, or electric dryer. Digital Power Management prevents overload conditions while allowing the generator to power multiple heavy loads, all while keeping your home cool and the lights on.

Guardian Standby Features

The Guardian models come equipped with True Power technology to provide utility-quality power to meet the needs of motors, appliances, and sensitive electronics. Less than 5% total harmonic distortion of the AC signal and voltage regulation within 1%, even under heavy load.

Compliance with National Fire Codes allows installation within 18 inches of the home, subject to local regulation and the location of nearby vents, windows, and doors.

A compact and attractive design, all-weather aluminum enclosure and quiet operation makes the 22kW unit practical in any residential setting. At 68dB, these generators produce noise that is lower than the average residential central A/C unit.

June 2014 Atlantic Hurricane Season off to a Slow Start

Satellite imagery shows the well organized storm system that could become a tropical cyclone off the coast of Florida later this week.

A well organized area of thunderstorms could easily become a tropical cyclone.

The end of June, 2014 brings the possibility for the first tropical cyclone of the season to the coast of Florida. At 2 PM EDT, an area of low pressure with thunderstorms was increasing in organization just 125 miles east of the coast of Florida. The National Hurricane Center gave an 80 percent probability this for the system to become a tropical depression within 48 hours.

Update 1 PM CDT: Depression 1 was upgraded to Tropical Storm Arthur at 11 AM Eastern time on July 1 with sustained winds of 40 MPH and a track that takes it up along the East Coast of the United States. Arthur is the first tropical cyclone of the Atlantic Season and may strengthen into a hurricane by Friday, July 4.

Elsewhere across the Atlantic Basin, Caribbean Sea, and Gulf of Mexico, no tropical cyclones have formed since the start of the Atlantic season.

The Northeast Pacific Ocean is a different story. There are two tropical storms (see graphic in next section) currently off the coast of Mexico. Tropical Depression 4E was upgraded to a tropical storm on Sunday, June 29. On Monday, June 30, another system intensified into a second tropical storm named Elida.

Satellite imagary shows two tropical storms side by side off the western coast of Mexico.

Twin Tropical Storms in the Eastern Pacific Ocean

The twin storms in the Eastern Pacific are the third and fourth named storms of the Eastern Pacific storm season. Two other named stormed have already run their course. Storms in this area of the Pacific Ocean don’t usually pose a threat to the United States, but often cause flooding, mudslides, and power outages along the coast of Mexico and Gulf of California, and the Baja Peninsula.

July Outlook

Hurricane season in the Atlantic, Caribbean, and Gulf of Mexico begins on June 1. Historically, tropical cyclones become more frequent and more intense as the season progresses from late spring through late summer. The season peaks during late August through late September with a historical average peak around September 10. The season declines during October and ends on November 30.

Tropical Storms, Hurricanes and Major Hurricanes can form at any time during the year and are not restricted to the hurricane season.

The 2014 Atlantic season forecast called for an unusually quiet hurricane season, and has thus far has met that expectation. There are no guarantees the season will remain quiet and the storm forming off the coast of Florida may become the first named Atlantic storm of the year. Given that long range forecasts have a low expectation of accuracy, there is a possibility that July could produce a number of storms.

Seasonal Impacts and Preparation

Tropical Storms and hurricanes produce high winds and torrential rainfall and cause flash floods and inland flooding, power outages, mud slides, and are responsible for numerous deaths every year.

Associated hazards of hurricanes include extreme storm surge and coastal flooding, extreme winds, and tornadoes. Storm surge can overwhelm natural and man-made water barriers and flood low-lying coastal areas. Flooding associated with hurricanes and tropical storms are responsible for loss of life and property damage every year.

Everyone living along coastal areas and inland from coastal areas affected by hurricanes and tropical storms should prepare in advance by:

  • understanding local evacuation plans and routes.
  • purchasing an NOAA weather radio.
  • building an emergency storm survival kit.
  • stocking non-perishable food and potable water for at least one week.
  • installing an emergency standby generator system or
  • have portable generator with installed manual transfer switch.
  • storing fuel supplies for portable generators.

When a storm threatens land:

Even though the 2014 forecast for the Atlantic hurricane season predicts fewer storms than most years, preparation is still important for those living on coastlines and inland regions. Prepare now.
