Most people discover how their gate behaves in an outage at the worst possible moment: in the dark, in the rain, with a vehicle idling and a gate that will not move. That is the case automatic gate battery backup Skagit County properties should be sized against.
What happens next depends entirely on decisions that were made years earlier, usually without anyone discussing them. Some gates keep working for a while on battery. Some open automatically and stay open. Some stop where they are and require somebody to find a release lever they have never used. And some do the last one while the owner stands there with a phone flashlight, reading a manual they downloaded ten minutes ago.
The useful thing about this problem is that it is entirely predictable. Every one of those behaviors is a design choice, and every one of them can be tested on a dry afternoon rather than discovered on a wet night.
There is one detail specific to Skagit County that changes the whole calculation. Most people size backup for a brief interruption. That is the wrong design case here. When a serious windstorm comes through, restoration is not measured in minutes, because crews have to visually inspect lines for hazards before power can safely be restored. That process means restoration can take several hours or multiple days. A backup system sized for a flicker is not backup. It is a delay.
What Happens to an Automatic Gate When the Power Goes Out?
Short answer: One of four things, depending on design. It may continue operating on battery backup for a limited number of cycles. It may open automatically and remain open, which some fire authorities require. It may simply stop, requiring manual release. Or it may have no provision at all beyond a release lever nobody has located. Every automated gate should have a manual release operable by one person, and in Skagit County backup should be sized against a multi day outage rather than a brief interruption.

The Four Things a Gate Can Do During an Outage
Every automated gate falls into one of these categories. Knowing which one you have is the starting point.
1. It keeps working on battery. A battery backup system carries the operator for a number of cycles, determined by battery capacity, gate load and how much else at the gate is drawing power. DC operators do this naturally, since they already run from a battery kept charged by the supply. AC operators generally require additional equipment to do it.
2. It opens automatically and stays open. Some fire authorities in this region require exactly this on gates serving fire apparatus access roads: on loss of power the gate opens automatically and remains open until power is restored. This surprises owners, because it is the opposite of what most people assume a security gate should do. It is a life safety provision rather than a convenience feature.
3. It stops where it is and waits for a manual release. The most common arrangement on older or simpler installations. The gate does nothing until somebody disengages the operator and moves the gate by hand.
4. It stops, and nobody knows what to do. Technically the same as the third case, but functionally worse. The release exists, and it is not documented, not labeled, and nobody on the property has ever used it.
Which of those you have is worth confirming today. Two of them are fine. One is a design decision that may be required. One is a problem, and it is the most common one.
Why the Design Case Here Is Days, Not Minutes
This is the section that changes how the rest of the article should be read.
Electricity in Skagit County comes from Puget Sound Energy, which serves all of Kitsap, Skagit, Thurston and Whatcom counties along with parts of Island, King, Kittitas and Pierce. Skagit Public Utility District, which operates the county’s largest water system, is a water utility rather than an electric one, which is a common local confusion worth clearing up.
Windstorms here produce large, broad outages. In a major regional windstorm, outages across western Washington have reached well over six hundred thousand customers at peak, with Skagit County and Whidbey Island heavily affected and communities including Mount Vernon, Sedro-Woolley and Conway losing power. Trees toppling onto lines are a primary cause.
Restoration is not fast, and there is a good reason. PSE describes a restoration process in which crews visually inspect power lines to identify and address hazards before safely restoring power. That step is why restoration can take several hours or even multiple days. It is a safety necessity, not an inefficiency, and it means the outage duration a property should plan for is not the brief interruption people imagine.
What that means for gate design:
Sizing for a few cycles is sizing for the wrong event. A battery that carries five or ten cycles covers a flicker. It does not cover a Thursday through Saturday without power after a wind event.
The manual release stops being a fallback and becomes the plan. In a multi day outage, whatever battery capacity exists will eventually be gone. What remains is a person and a release lever. That is why the release, its documentation and whether a single person can actually operate that specific gate are more important than the battery specification.
Outages cluster with the worst weather. The storm that causes the outage is also the night you least want to be standing at the gate. It is also, for a solar gate, a period of very poor charging.
And the timing is not evenly distributed. These events concentrate in the wet, windy months, which is also when daylight is shortest and when a stranded vehicle at a gate is least pleasant.
Planning a gate in Mount Vernon, Sedro-Woolley or elsewhere in Skagit County? The right backup design starts with an honest answer about how long you need the gate to work, which here is longer than most people assume. Emerald Gate Systems evaluates gate power and backup as part of the overall system design. Request a gate evaluation: call (425) 879-9400 or schedule a free consultation call.
How Battery Backup Actually Works
The mechanics are worth understanding because they explain most of the failure modes.
In a DC system. The operator runs from a battery. Utility power runs a charger that keeps the battery topped up. When utility power disappears, nothing changes from the operator’s perspective; it continues drawing from the battery until the battery is depleted. This architecture is inherently backed up, which is one of its main advantages.
In an AC system with battery backup. The operator normally runs on line voltage. A backup arrangement provides an alternative source when line voltage is lost. The specifics vary by product, and the capacity and behavior should come from the manufacturer’s documentation for that model.
What the battery is actually doing. It is a reservoir. It has a finite capacity, it is drawn down by everything at the gate, and it is refilled only when there is a source. During an outage there is no source unless there is solar, and in a winter storm solar is producing very little.
The three numbers that matter:
Capacity. How much energy the battery holds. Larger capacity means more cycles, more cost and more physical space.
Draw per cycle. How much energy one open and close consumes, which depends on the operator, the gate’s weight and length, and how far it travels.
Continuous draw. Everything at the gate that consumes power all the time: the control board, a keypad, an intercom, a camera, a cellular device, loop detectors, lighting. This is the number owners consistently forget, and during a long outage it can matter more than the cycles.
That third number is why “we hardly use the gate” is not reassuring. A gate that is never opened still has a control board and possibly a camera drawing power around the clock. In a three day outage, the continuous load can empty a battery without the gate moving once.
What Determines How Many Cycles You Get
There is no universal number, and any vendor who states one without asking about your gate is guessing. The variables:
Battery capacity and condition. A new battery at full capacity and a five year old battery at reduced capacity give very different answers.
State of charge when the outage began. A battery that was already partially depleted starts lower.
Gate weight and travel distance. A wide, heavy cantilever gate consumes considerably more per cycle than a light aluminum swing leaf.
Operator efficiency. Different operators consume different amounts for the same work.
Everything else at the gate. The continuous loads described above, running for the entire outage.
Temperature. Cold reduces available capacity, discussed below.
How the system manages itself. Some systems reduce function as the battery depletes, some warn, and some simply stop. Knowing which yours does is useful.
The practical approach. Ask for the expected cycle count for your specific installation, have it established at commissioning, and write it down. Then re establish it whenever a device is added at the gate, because adding a camera two years later changes the answer without anyone recalculating.
The Silent Failure: Batteries Degrade Invisibly
This is the most common reason a backup system fails when it is finally needed.
Batteries lose capacity gradually. They do not announce it. A battery bank that has lost a large fraction of its original capacity will still show voltage, still operate the gate normally on a good day with utility power present, and give no indication that it can no longer carry an outage.
Which means the failure is discovered at the worst moment. The owner has had backup for years, has never tested it, and finds out during the storm that it is not there anymore.
Age matters independent of use. Batteries have a service life whether or not they are cycled hard, and temperature affects it. An enclosure that gets hot in summer or cold in winter shortens it.
The fix is unglamorous and effective. Treat batteries as a consumable with a replacement schedule rather than as a component that fails. Record the installation date. Assess condition on a maintenance interval. Replace on a planned cycle rather than after an outage exposes the problem. DASMA’s inspection checklist for automated vehicular gate systems includes battery condition and age among the items covered, along with the battery backup controller and motor.
And revisit the calculation when anything changes. Cameras, intercoms and cellular equipment installed after the original design consume capacity that was never allocated to them.
Cold Weather Takes Capacity Away Too
A compounding factor that is easy to overlook.
Battery performance declines at lower temperatures. The available capacity at freezing is lower than at room temperature, which means the number of cycles a battery will deliver in January is lower than the number it delivered during a summer test.
The compounding is unfortunate. The coldest period is also the darkest, which matters if there is solar; it is also the windiest, which is when outages happen. The three factors line up against you rather than averaging out.
Design responses:
Size with the cold weather figure in mind, not the best case.
Consider enclosure location and thermal exposure. An enclosure in a sheltered position behaves differently from one fully exposed.
Test in winter, not in July. A backup test conducted in August tells you about August.
Know that the manual release becomes more likely to matter, because the combination of reduced capacity and a longer outage brings it forward.
The Manual Release Is the Thing That Always Works
If you take one action after reading this article, make it this one.
Every automated gate should have a manual release that allows the gate to be operated by one person. This is not merely good practice. Where a gate serves a fire apparatus access road, the fire code contemplates construction that allows manual operation by one person, and the emergency operation provision must be maintained operational at all times.
Four things to verify, and they take fifteen minutes:
1. Where is it? Physically locate the release on your gate. Photograph it.
2. How does it work? Operate it. Not read about it. Actually disengage the operator and move the gate.
3. Can one person really do this? On a wide, heavy gate this is a genuine question. If it takes two people, or if it takes a tool nobody can find, the requirement is not being met in practice.
4. How does it re engage? Knowing how to put the gate back into normal operation matters as much as releasing it, and it is frequently the part people get wrong.
Then document it. A photograph and three sentences, kept somewhere findable, and shown to more than one person on the property. On a commercial or shared property, this belongs in a written procedure, because staff and board members change and the knowledge leaves with them.
And keep it maintained. A release mechanism that has never been used in eight years may be seized, corroded or obstructed. In this climate that is a realistic concern, and it belongs on the maintenance list.
One caution. Do not confuse the manual release with forcing the gate. If a gate will not move under power, releasing it and moving it by hand is appropriate. Pushing a gate that is bound, or that is still under power, is not.
Fail Open, Fail Secure, and Why It Varies by Jurisdiction
This is the design question owners least expect, and the answer is not the same everywhere in Northwest Washington.
The two philosophies.
Fail secure means the gate stays closed when power is lost. It preserves the security boundary. It also means nobody gets in or out until somebody uses the manual release.
Fail open means the gate opens on loss of power and stays open. It preserves access, including emergency access, at the cost of the security boundary for the duration of the outage.
Fire authorities in this region take different positions, and it matters. Requirements published by fire authorities in Northwest Washington include provisions for how a gate must behave during a power failure, and in some jurisdictions the requirement is that the gate open automatically and remain open until power is restored, or that it be capable of being pushed open without power. Neighboring jurisdictions publish different expectations, including exemptions based on the number of dwelling units served.
Which means this is not a preference question if your driveway is a required fire apparatus access road. It is a requirement question, and the answer comes from the authority for your address.
In Skagit County, the county’s published access standards indicate that a fire apparatus access road must be provided where a facility or building is located more than one hundred fifty feet from fire apparatus access, and that security gates across fire access roads must be approved by the Skagit County Fire Marshal. The Fire Marshal’s Office is located at 1800 Continental Place in Mount Vernon and can be reached at (360) 416-1841. Properties inside city limits should confirm with their city’s fire department, such as Mount Vernon’s or the Burlington Fire Marshal’s Office at (360) 757-6684.
Two practical points regardless of the requirement:
Whatever behavior is required has to be tested. A gate that opened on power loss at commissioning may not do so three years later, because a battery degraded, a setting changed during a service call or a component was replaced with one configured differently.
And it has to work at a depleted battery, not only when the system is healthy. That is precisely the condition a multi day outage produces.
Battery, Solar or Generator: A Comparison
| Approach | What it covers | Advantages | Limitations | Suitability in a multi day Skagit outage |
|---|---|---|---|---|
| Battery backup only | A defined number of cycles after power loss | Simple; no additional infrastructure; inherent in DC operators | Finite; degrades silently; reduced by cold and by continuous loads | Covers the first part of an outage, then depends on capacity |
| Battery plus solar | Cycles plus partial recharging | Can extend operation indefinitely if generation exceeds consumption | Winter storms are exactly when solar generation is lowest here | Helps, but should not be assumed to carry a dark, wet multi day event |
| Larger battery bank | More cycles | Straightforward; addresses the actual failure mode | Cost, space, and more batteries to replace on schedule | The most direct answer if continued operation matters |
| Generator serving the property | Everything, including the gate | Covers the whole property; not gate specific | Cost, fuel, maintenance, permitting and placement; needs the gate circuit included | Strong, if the gate circuit is actually on the backed up panel |
| Manual release only | Nothing automatic; a person operates the gate | Always available; no capacity to deplete; no maintenance beyond keeping it functional | Requires a person, and requires that person to be able to move that gate | The universal fallback, and the reason it must be tested |
| Fail open on power loss | Access preserved for the outage duration | Nobody is trapped; emergency access unimpeded; may be required | Security boundary is open for the duration | Depends on requirement and on the owner’s risk view |
One point the table makes indirectly. If a generator serves the property, the gate is only backed up if the gate circuit is on the backed up panel. That is frequently not the case, because the gate is a distant circuit that nobody thought about when the generator was specified. It is worth checking.
What Skagit County Property Owners Should Consider
PSE is the electric utility here, serving all of Skagit County among others. Skagit PUD is water. This matters when you are looking up outage information or reporting a problem.
Windstorms are the dominant outage driver, and they hit this county hard. Regional wind events have produced very large outages with Skagit County among the heavily affected areas, including Mount Vernon, Sedro-Woolley and Conway. Trees on lines are a primary cause.
Restoration takes time for a legitimate reason. PSE describes crews visually inspecting lines to identify hazards before restoring power, which is why restoration can run to several hours or multiple days. Plan for that duration rather than for a flicker.
Valley and upland properties differ. Low lying valley properties deal with saturated ground and drainage at the gate line, which affects everything from foundations to loop longevity. Properties toward the foothills and up the Skagit River valley deal with more tree cover and longer distribution runs. Both matter for backup planning, and the second more directly.
Wet, not frozen, is the baseline condition, which affects the backup discussion in a specific way: water intrusion into enclosures is the leading electrical failure mode at gate installations here, and a corroded connection can defeat a perfectly healthy battery.
Winter darkness is long. At this latitude mid winter darkness runs roughly sixteen hours, which reduces what solar can contribute during exactly the season when outages are most likely, and increases the draw of anything light activated at the gate.
Rural properties frequently have one way in. Where the gate is the only access, its outage behavior is not a convenience question. It is the difference between being able to leave and not.
And the fire access requirement may decide it for you. If the driveway is a required fire apparatus access road, the required behavior on power loss is set by the authority rather than by preference.
Lost power in a storm and found your gate would not open? That is worth diagnosing rather than repeating. Emerald Gate Systems evaluates gate backup power, battery condition, manual release function and emergency access provisions across Skagit, Snohomish and Whatcom counties. Request a gate evaluation: call (425) 879-9400 or schedule a free consultation call.
What Determines the Cost of Gate Backup Power
Costs vary with the gate, the load and how long you want the system to last. What moves the number:
Required duration. The single biggest driver. Covering a few cycles is inexpensive. Covering a multi day outage with a heavy gate and continuous accessory loads is a different scale of battery.
Gate weight and travel. Determines draw per cycle, and therefore how much capacity a given number of cycles requires.
Continuous accessory load. Cameras, intercoms, cellular equipment and lighting consume capacity around the clock. This is frequently the dominant load in a long outage.
Operator architecture. DC systems have battery capability inherently. AC systems generally require additional equipment.
Battery chemistry and expected service life. Different chemistries differ in up front cost, cold weather behavior and replacement interval. The honest comparison is over the life of the system rather than at purchase.
Enclosure and mounting. Larger battery capacity needs physical space, and thermal exposure affects service life.
Solar, if included. Panel, controller and mounting, sized against the design month rather than an annual average.
Generator integration, if applicable. Whether the gate circuit can be added to a backed up panel, and what that requires.
Ongoing. Battery replacement on a planned cycle, plus the maintenance visit that assesses condition.
Project costs vary substantially based on site conditions and system design. A proposal that does not state the expected cycle count for your specific gate, including continuous loads, has not sized the system.
How to Test Your Gate Before You Need To
Do this on a dry afternoon. It takes half an hour and it is the highest value thing in this article.
- Find the manual release. Physically. Photograph it in place.
- Operate it. Disengage the operator and move the gate by hand, both directions.
- Confirm one person can do it. Not two. One.
- Re engage it and confirm normal operation resumes.
- Simulate a power loss if it can be done safely, and observe what the gate does. Does it keep working? Does it open and stay open? Does it stop?
- If it operates on battery, count the cycles or ask the technician to establish the figure during a service visit, then write it down.
- Check the battery installation date. If nobody knows it, that is the answer.
- List everything at the gate that draws power continuously, and ask whether it was included in the original sizing.
- If there is a generator, confirm whether the gate circuit is on the backed up panel.
- Confirm the emergency access provision works, including any fire department override, and that it does not depend on the network or access control platform.
- Write it all down in plain language, and show at least one other person.
- Repeat annually, and after any service call that touched the operator or its settings.
Common Mistakes in Gate Backup Planning
Sizing for a brief interruption. The design case in this county is a multi day windstorm outage, not a flicker.
Forgetting continuous loads. A camera and a cellular device can empty a battery over three days without the gate moving.
Adding accessories without recalculating. The most common way a working backup quietly stops being adequate.
Treating batteries as permanent. They degrade silently and reveal it only when needed.
Never testing the manual release. The single most common and most consequential omission.
Assuming one person can move a heavy gate. On a wide gate this deserves verification rather than assumption.
Letting the release mechanism seize. Eight years unused in a wet climate is enough.
Assuming the generator covers the gate. Only if the gate circuit is on the backed up panel, which it frequently is not.
Expecting solar to carry a winter outage. The storm that causes the outage is also a period of very poor generation.
Not knowing which behavior the fire authority requires. Fail open is a requirement in some jurisdictions and a surprise in most conversations.
Testing in summer. Cold reduces capacity, and outages happen in winter.
No documentation. The knowledge leaves with whoever had it.
Questions to Ask About Outage Behavior
- What does this gate do when power is lost: keep working, open and stay open, or stop?
- If it operates on battery, how many cycles, for this specific gate, including all continuous loads?
- When were the batteries installed, and what is their expected service life?
- What happens to that cycle count in cold weather?
- What is drawing power at this gate around the clock, and was it in the original sizing?
- Where is the manual release, and has anyone here operated it?
- Can one person operate it on this gate?
- How does the gate re engage after manual operation?
- Is this driveway a required fire apparatus access road, and what behavior does the fire authority require on power loss?
- Does the required emergency behavior still work when the battery is depleted?
- Does the emergency access depend on the network, the access control platform or the intercom?
- If we have a generator, is the gate circuit on the backed up panel?
- What would it cost to extend backup to cover a multi day outage?
- What maintenance does the backup system need, and is battery assessment included?

Frequently Asked Questions
Will my automatic gate work during a power outage?
It depends on how it was designed, and there are four possibilities. It may continue operating on battery backup for a limited number of cycles. It may open automatically and remain open, which some fire authorities require. It may stop and require manual release. Or it may stop with no documented release procedure, which is the same as the third case but worse in practice. Every automated gate should have a manual release that one person can operate, and that release should be located and tested before it is needed.
How many times will my gate open on battery?
That is a specific number for a specific installation, and any general figure is unreliable. It depends on battery capacity and condition, the state of charge when the outage began, gate weight and travel distance, operator efficiency, temperature, and everything at the gate drawing power continuously. Have the figure established at commissioning or during a service visit, write it down, and re establish it whenever a device is added at the gate.
How long do power outages last in Skagit County?
Longer than most people plan for. Puget Sound Energy, which serves Skagit County, describes a restoration process in which crews visually inspect power lines to identify and address hazards before safely restoring power, and notes that because of this step restoration can take several hours or even multiple days. Major regional windstorms have produced very large outages with Skagit County among the heavily affected areas, including Mount Vernon, Sedro-Woolley and Conway. Size backup against that duration rather than a brief interruption.
How do I open my gate manually?
Every automated gate should have a manual release that disengages the operator so the gate can be moved by hand. Where the release is and how it works varies by operator, which is exactly why it should be located, operated and documented on a dry afternoon rather than found in the dark. Confirm that one person can actually move your gate, and learn how to re engage normal operation afterward. Do not force a gate that is bound or still under power.
Why did my gate stop working days after the storm?
Most likely because it was running on battery the entire time and finally depleted it. Many operators fall back to battery on loss of utility power without any obvious indication, so the property continues using the gate normally while the reservoir drains. If the outage was extended, or if the batteries had degraded, the gate stops at whatever point capacity ran out. It is also worth confirming the property actually has utility power restored, since that is a surprisingly common cause of a gate that seems dead.
Should my gate open automatically when the power fails?
That depends on the fire authority for your address, and it is not always a matter of preference. Requirements published by fire authorities in Northwest Washington include provisions for gate behavior during a power failure, and in some jurisdictions gates serving fire apparatus access roads are required to open automatically and remain open until power is restored, or to be capable of being pushed open without power. Neighboring jurisdictions publish different expectations. Confirm the requirement for your property before selecting an operator.
Do batteries wear out even if the gate is not used much?
Yes, and this is why backup systems fail quietly. Batteries have a service life whether or not they are cycled hard, and temperature affects it. A degraded bank will still show voltage and still operate the gate normally with utility power present, giving no indication that it can no longer carry an outage. Record the installation date, assess condition on a maintenance interval, and replace on a planned schedule rather than after an outage exposes the problem.
Does cold weather affect gate battery backup?
Yes. Battery performance declines at lower temperatures, so the available capacity in January is lower than in a summer test. The unfortunate part is that the factors compound: the coldest period is also the darkest, which limits any solar contribution, and it coincides with the windy months when outages are most likely. Size with the cold weather figure in mind, and if you test the system, test it in winter rather than in August.
Will solar keep my gate running through an outage?
It helps, and it should not be assumed to carry a multi day winter event. Solar’s advantage is genuine independence from the utility, which matters here. Its limitation is that the storms that cause outages coincide with the season of lowest generation, and published solar resource figures for this region put December at a small fraction of the summer figure. A solar gate in a dark, wet, multi day outage is running mostly on stored energy, which brings the sizing conversation back to battery capacity.
If I have a generator, is my gate covered?
Only if the gate circuit is on the backed up panel, and frequently it is not. A gate is usually a distant circuit that nobody considered when the generator was specified, which means the house has power and the gate does not. This is worth checking rather than assuming, and adding the gate circuit to a backed up panel is a straightforward conversation with an electrical contractor if the capacity exists.
What if my gate is the only way onto my property?
Then the outage behavior is not a convenience question and deserves more investment. In that situation the manual release is your actual contingency plan, so it must be located, tested, documented and known to more than one person. Backup capacity sized against a multi day outage becomes a reasonable expense rather than a luxury. And if the driveway is a required fire apparatus access road, the required behavior on power loss is a matter for the fire authority rather than for preference.
How much does it cost to add battery backup to a gate?
It varies substantially, and the largest driver is how long you want the gate to keep working. Covering a handful of cycles is inexpensive. Covering a multi day outage on a heavy gate with cameras and connectivity at the entrance is a different scale of battery, plus enclosure space. Other factors include operator architecture, since DC systems have the capability inherently while AC systems generally need additional equipment, battery chemistry and its replacement interval, and whether solar is added.
How often should backup be tested?
At least annually, and after any service visit that touched the operator or its settings. A yearly test should include operating the manual release, confirming one person can move the gate, simulating power loss if it can be done safely, verifying the required emergency behavior, and assessing battery condition and age. Testing in winter is more informative than testing in summer, because cold reduces capacity and winter is when outages occur.
Automatic Gate Battery Backup Skagit County: Final Thoughts
The gate industry talks about battery backup as a feature. In Skagit County it is better understood as a duration question, and the honest duration is longer than the marketing suggests.
Wind takes trees down. Trees take lines down. Crews have to walk the lines and clear hazards before anything can be re energized, which is why restoration is measured in hours and days rather than minutes. A backup system designed around a brief interruption will do exactly what it was designed to do, and then stop, sometime on the second morning.
That is not an argument against battery backup. It is an argument for sizing it honestly, for counting the camera and the cellular device that draw power all day whether or not the gate moves, for treating batteries as a consumable with a replacement date, and for testing in January rather than August.
And it is an argument for the least technological item in this entire article. At the end of every backup system, however well designed, there is a person and a release lever. Whether that works depends on four things you can verify this afternoon: where the release is, whether it moves, whether one person can do it, and whether more than one person on the property knows.
Fifteen minutes now, or twenty minutes in the rain with a flashlight later.
