When the Lights Go Out: Is Your Business Ready for an Outage?

A couple of weeks ago, I had a power outage at home. It wasn’t the usual culprit, not a storm, not a car accident involving a power pole, and not a tree falling on the lines. Instead, it came down to something far more ordinary: the age of the fuses in the roadside box feeding electricity to our house.

The failure happened late at night, which was a blessing. Only a few appliances were running, and the timing meant no disruption to work or family commitments. Within 90 minutes, a linesman arrived, replaced the failed fuses, and restored the power. It was an inconvenience but not a disaster. Why? Because we were prepared.

We had backup power options, candles, and fully charged phones. The interruption was short-lived and manageable.

But that experience raised a bigger question in my mind: How would your business cope with a 90-minute outage?

Why Preparation Matters

For a household, a short outage is a nuisance. For a business, even a brief interruption can mean serious consequences. A 90-minute power cut might not sound long, but consider what could happen in that timeframe:

• Lost sales: A café, bar, or restaurant could lose peak service revenue. Customers might walk out, and you may never see them again.

• Interrupted operations: Manufacturers or workshops could face stalled production, equipment resets, or even wasted raw materials.

• Customer dissatisfaction: If your business relies on online platforms, call centres, or deliveries, clients may experience delays or failed transactions damaging your reputation.

• Data risks: If systems shut down without warning, unsaved data or corrupted files could add hours (or days) of recovery work.

The reality is that every business is more dependent on power than it often realises not just for keeping the lights on, but for keeping operations smooth, customers happy, and teams productive.

What Businesses Can Learn from a Small Outage

 My brief experience at home illustrates a critical point for business leaders: outages don’t always come with warnings, and they’re not always dramatic. Sometimes it’s the small, ageing piece of infrastructure, like a fuse, that can suddenly put everything on hold.

This is where business resilience planning comes in. It’s not about imagining once-in-a-lifetime disasters but about anticipating the everyday failures that are far more likely to occur.

Ask yourself:

• Does your business have backup power solutions such as UPS systems or generators?

• Are your staff trained to handle outages safely and efficiently?

• Do you have contingency plans for customer service when systems go offline?

• How quickly can your business bounce back from even a 30–90 minute interruption?

Turning Risk into Strategy

At Josty, we work with businesses to uncover the vulnerabilities that could quietly erode performance or profits. A 90-minute power cut might be rare, but the ability to withstand and adapt to disruptions is what separates resilient businesses from fragile ones.

Resilience is not just about technology; it’s about culture and strategy. Do your people know what to do? Do your processes allow for quick pivots? Do your systems have redundancies built in?

The outage at my home was a reminder that resilience isn’t about avoiding every problem it’s about being prepared enough that when problems come, they don’t knock you off course.

Final Thoughts

A power outage at home may only cost you a couple of candles and a late-night wait for the linesman. But in business, the same event could mean lost sales, unhappy customers, wasted stock, or shaken confidence in your reliability.

So, here’s the challenge: if your business faced a 90-minute outage tomorrow, would you be ready?

At Josty, we believe that resilience planning is not optional, it’s a performance driver. Preparing for the unexpected allows businesses to protect their bottom line, strengthen their reputation, and deliver consistent value to customers.

The question isn’t whether outages or disruptions will happen, they will. The real question is whether your business is prepared to handle them without missing a beat.

What Is the Best Type of Backup Solution for Your Critical Load?

When it comes to critical load backup solutions, the answer isn’t about choosing a trendy product or the most aggressively marketed system it’s about finding the one that will perform flawlessly when you need it most.

A true backup system must supply your load for the required backup time, even while everything else is failing around it. This means it must be sized and designed for your specific application, be robust enough to withstand environmental and operational stress, and have redundancy built in so there are no single points of failure.

Why “One-Size-Fits-All” Doesn’t Work

Recently, I saw a post promoting one type of backup solution over another. The problem? The arguments were technically flawed and clearly driven by a sales agenda rather than actual performance data. In backup power, such oversimplification can lead to costly mistakes and in worst-case scenarios, critical operational downtime.

Every site, application, and environment has its own demands:

• Load characteristics (voltage, current, inrush requirements)

• Backup duration (seconds, minutes, or hours)

• Environmental conditions (temperature, humidity, vibration)

• Operational priorities (safety systems, communications, process control)

Why Battery-Backed DC Systems Deserve Attention

For many applications, battery-backed DC systems offer a reliable and predictable way to protect critical loads. When properly designed:

• They eliminate conversion losses seen in AC-only backup setups.

• They respond instantly, there’s no switchover lag.

• They can be configured for n+1 redundancy to avoid single points of failure.

• They integrate well with renewable energy inputs and advanced monitoring systems.

However, the key word here is “properly designed.” An undersized battery bank or poorly specified charger can fail under stress, leaving your systems unprotected. That’s why it’s vital to work with an expert who understands both the theory and the field realities.

Redundancy Is Non-Negotiable

Even the best-built system can fail. That’s why redundancy should be a non-negotiable part of your backup design.

• Dual strings of batteries prevent total outage if one fails.

• Redundant chargers ensure batteries stay at optimal charge.

• Multiple feeds or paths avoid a single fault taking the system down.

Think of redundancy as insurance for your insurance.

The Cost of Getting It Wrong

Downtime from an inadequate backup system doesn’t just mean a temporary inconvenience—it can result in:

• Production losses worth thousands (or millions) of dollars.

• Safety risks to personnel.

• Compliance breaches that bring fines and reputational damage.

When weighed against these risks, investing in the right system from the start is not just a technical decision, it’s a strategic business decision.

Expert Guidance Is Critical

The best backup system is not necessarily the most expensive or the most heavily advertised it’s the one engineered for your exact needs. Avoid decisions based on:

• Outdated technical assumptions.

• Sales pitches without site-specific data.

• “It worked for them, so it will work for us” thinking.

Instead, bring in a specialist who can analyse your:

• Load profile.

• Redundancy requirements.

• Budget constraints.

• Compliance obligations.

The Josty Approach

At Josty, we believe in engineering solutions that empower growth and secure success. Our backup designs are tailored, tested, and backed by decades of hands-on industry experience. We understand the cost of failure and we make sure your systems are ready when it matters most.

Bottom line: The best type of backup solution is one that isn’t going to let you down when you need it most. It needs to be sized and designed for your application, be robust, and have redundancy to eliminate single points of failure. Don’t get caught out by clever marketing talk to an expert and make a decision based on facts, performance, and reliability.

Is your battery bank truly capable of providing the backup you need?

 It’s a simple question but one too many electrical professionals leave unanswered until it’s too late.

When did you last audit your DC battery system?

The battery bank is the last line of defence in any critical electrical system—whether it’s a substation, industrial control system, telecom site, hospital, or process plant. And yet, many are designed on assumptions rather than solid, real-world data. The result? Unreliable backup, accelerated degradation, and systems that may not hold up when you need them most.

Let’s ask some hard questions

• Was the battery sized correctly?
  Was a detailed load profile used, accounting for the actual connected loads and load drop-off logic? Or was it a best guess, recycled from a similar project?
  If your system wasn't built using real-time measured data or an accurate forecast of load demands, there’s a good chance it’s either undersized or overengineered in the wrong areas.

• Were the right design contingencies applied?
  You can’t just look at nominal capacity. Temperature corrections, expected aging over 10–15 years, float charging behaviour, and maximum expected ambient conditions must all be considered.
  Many failures occur not due to battery faults, but due to poor thermal planning or inadequate aging margin.

• Is the battery type fit for purpose?
  It’s not just about lead-acid vs. lithium. It’s about:

  • Maintenance access

  • Ventilation and gassing considerations

  • Frequency of cycling

  • Environment (indoor vs outdoor, hot vs cold, clean vs corrosive)

  • Expected lifespan and serviceability

Too often, battery decisions are based on budget constraints or rough sizing estimates. But the cheapest option upfront often becomes the most expensive mistake down the line especially when critical operations are disrupted due to battery failure or backup insufficiency.

The reality of DC system neglect

At Josty, we regularly conduct audits across a wide range of industries from utilities to infrastructure and industrial applications. One common pattern? The DC system is often overlooked once commissioned. It’s assumed to be “set and forget.” But that’s a dangerous assumption.

We’ve seen sites where:

• Battery banks were still operating years beyond their rated life

• Load profiles had changed dramatically since the original installation

• Autonomy requirements increased but weren’t reassessed

• Ventilation and room conditions had degraded over time

• There was no clear maintenance schedule or test data history

And when problems strike during an outage or load shed it’s always the battery that gets blamed. But the problem almost always starts earlier… in the design, selection, and maintenance of the system.

How Josty can help

We specialise in helping businesses audit and optimise their DC systems and battery backup. Our process includes:

• Reviewing the original design, spec, and as-built installation

• Verifying site conditions, environment, and current load behaviour

• Testing and inspecting the battery health and performance

• Identifying risks, gaps, and opportunities for lifecycle improvement

• Delivering clear, actionable recommendations for compliance and performance

You’ll receive a detailed report tailored to your site’s conditions and business needs whether that’s ensuring redundancy, extending service life, or planning for future load expansions.
