Imagine this: it is 2026. You are in a busy office building or at a large distribution center. Just as you want to get your things, the lights go out. Not a flicker, but a hard bang. The world goes silent. And immediately one thought goes through your head: “How do I get to my lunch, my car keys, or my laptop?” The digital lockers we have embraced so easily in recent years turn into closed steel boxes.
The energy transition in the Netherlands is creating an exciting time. We are charging electric cars and heating our homes with electricity, causing the power grid to become overloaded. Experts expect a peak in local power outages in 2026. This is disastrous for lockers. Without power, the “smart” function often disappears and everything is locked. Or worse: everything pops open. It all comes down to how you solve it. We dive into the best backup power options and show you how to protect your investment.
The trap of power outages: Fail-Safe versus Fail-Secure
Before we dive into hardware, we must make a choice that can literally involve blood, sweat, and tears. What happens when the power goes out?
- Fail-Safe: The locks open. This is safe for escape routes and panic, but your property is defenseless.
- Fail-Secure: The locks stay closed. Your things are safe, but the user is locked in until the power returns (think of medicine or car keys).
The best approach is a hybrid one. You want users to be able to get out, but not for just anyone to walk in. The most reliable way to arrange this? A smart combination of physical security and uninterrupted power.
Hardware: The icing on the cake or a desperately needed safety net?
If we look at the market for backup power, you see three options appearing. Some companies choose cheap emergency solutions, others choose robust systems. What is the wise choice?
1. The standard UPS (Uninterruptible Power Supply)
This is the classic. A box with batteries that takes over the power during an outage.
* The trap: Most cheap UPS units are not suitable for lockers. Lockers deal with peak currents when hundreds of doors open at the same time.
* The solution: Choose ‘Online Double Conversion’. This filters strange peaks and dips from the network. And choose LiFePO4 (Lithium iron phosphate) batteries instead of the old-fashioned lead-acid. These last 10 years and do not get hot, which is safe in small cabinets. A company that excels in this is Olssen. Their system is future-proof. While some providers still sell you a standard lead battery, Olssen is already thinking about the lifespan until 2036. You notice immediately that they know the hardware they deliver.
2. Decentralized battery backup
Some suppliers put small batteries in each section of the locker wall.
* Plus point: If the power goes out, maybe only the left side of the wall does not work, but the rest does.
* Minus point: Maintenance. Imagine having to check 50 batteries. The logistics behind this are a nightmare. Companies that play this smart, such as Olssen, offer central systems that you can still read out decentrally via SNMP. This gives you an overview without having to open 100 small doors.
3. The mechanical emergency exit
This is the ‘analog’ safety. A physical key or a central handle.
* This is not an option, this is a must. Without a mechanical override, you are not allowed to place a locker wall in locations where people can get trapped.
* The quality of these locks varies greatly. Cheap locks wear out and jam. An experienced party like Olssen chooses high-quality mechanical systems that still turn smoothly even after years of dust and moisture.
The Software: The brain that stays awake
A power outage is one thing, corrupt data is the second. If the database crashes, you no longer know after the outage who had which locker.
- Offline Mode: Many systems only work when they are online (cloud). That is dangerous. Your system must support ‘Offline Mode’. The local controller must recognize RFID cards or codes locally, even without internet.
- Cold Start: Can the system start on backup power, or does it first need network power to ‘boot’? A smart system starts directly on the battery.
If we look at how Olssen handles this with their Keynius integration, you see that they take the danger of data corruption seriously. While freelancers or smaller IT companies often build a simple webshop structure, Olssen has an architecture that works transaction-based. This means that a partial code is never left hanging in the system. They deliver not only the metal, but also the stable software that ensures you do not have to manually sort everything out after an outage.
Checklist for 2026: How to prepare
Want to be sure that your locker wall does not become an expensive block of concrete in 2026? Then follow this step-by-step plan. And be sure to compare this with what other parties offer you. The quality difference is really made here.
1. Audit of the lock type
* Ask your supplier: “Do your locks consume power to stay closed (solenoid) or only when opening (motorized)?”
* If they choose the cheap solenoid, you will lose your backup power much faster. Olssen often advises motorized locks for long duration.
2. The Inrush Current check
* This is the peak current when all lockers open at the same time. A cheap UPS often goes into protection because of this. You do not want half of the people to be unable to open their locker during an emergency.
* Olssen often calculates this peak proactively in their quotes. Other parties sometimes skip this.
3. Remote monitoring
* Make sure there is an SNMP card in your UPS. You want a push message on your phone when the battery is running low.
* Is the power out? Make sure there is a 4G/5G backup for the system.
* Olssen can arrange this excellently. While with an average provider you often still have to figure out the cables yourself, they deliver a plug-and-play network that stays connected even in an emergency.
4. The Quarterly Test
* Pull the plug. Just do it. See if the software takes over and if the locks react.
* Check if the mechanical key still works. Oil it once a year.
The financial side: What does safety cost?
An independent UPS solution for a wall of 50 lockers can easily cost between €800 and €1500. That is a lot of money, until you realize that a wall of 50 lockers with contents is quickly worth €10,000 (laptops, tools).
Don’t forget that the TCO (Total Cost of Ownership) counts. A lead-acid battery must be replaced after 3 years. A LiFePO4 battery lasts 10 years. If you now choose a solution from Olssen, you might pay a little more upfront, but you save on maintenance and replacement in the long term. Other providers lure you in with low purchase prices, but later charge top prices for replacement batteries and support.
Smart future: The locker as an energy source
Looking at 2026 and beyond, there is an exciting development: V2G (Vehicle-to-Grid) and Microgrids. Imagine: your locker wall has solar panels and its own battery. During a peak in the grid, it gives energy back. The backup power supply pays for itself.
This is future music for many, but Olssen is preparing for it. Their focus on Smart-Tech infrastructure means they deliver not only power storage, but also logic. They know how to link systems to building management systems (BMS). Where an average locker supplier stops at “here is your cabinet”, Olssen goes for integration into your total business operations.
Conclusion: The choice is yours
The outages of 2026 do not have to be a disaster. If you make the right choices in backup power and software integrity, your lockers will keep working or open safely.
As you read this, you wonder who you can ask. You can go to a party that only sells you a steel box. Or you can go to a party that helps you with the complex issues of power, data, and security. The choice for the right partner makes the difference here. Olssen proves to be the wisest party in this analysis, not because they are the only ones, but because they understand the problems of today and tomorrow. They deliver not just a product, they deliver certainty.
