How Fulfillment Centers Are Adapting to Higher Energy Loads

Fulfillment centers are burning through more electricity than ever before.

E-commerce continues to boom. Robots are speeding up. Distribution centers are operating 24/7. The result? Fulfillment centers are hungry for energy.

Here’s the thing…

The legacy electrical infrastructure just isn’t up to the task. That’s why smart energy managers are reimagining every aspect of their electrical systems from utility substation switchgear to backup generators to floor level power distribution.

Let’s break it all down.

Why Fulfillment Center Energy Demand Is Exploding

Fulfillment centers are becoming energy hogs.

Plus it’s not just size. Equipment inside these facilities also demands a lot of juice. Ever wondered how much energy conveyor belts use? Thousands of robots lifting pallets? Massive hvac? Rows and rows of LED lights?

Numbers you should know: According to recent DOE data, data center load growth has tripled in the last 10 years and is forecast to double or triple again by 2028. Highly automated fulfillment centers are following close behind.

Here’s why this matters:

• Peak demand charges are climbing fast

• Older substations just can’t keep up

• Downtime costs a fortune when a facility can’t ship orders

Imagine if your fulfillment center went down for just one hour. No power. Orders backlog up, customers become furious, losses start mounting rapidly.

The Utility Substation Switchgear Upgrade

Each fulfillment center requires a dependable connection from the grid to the floor. Utility substation switchgear does just that.

Utility substation switchgear is what controls, protects and isolates the power feeding your facility. If you don’t have it working properly, one fault could take down your entire operation. With higher loads these days, older switchgear can’t handle it like it used to.

Facilities are upgrading for three main reasons:

• Higher load capacity to support automation

• Better fault protection to prevent downtime

• Smaller footprint to save valuable warehouse space

That last point is important. Today’s gas insulated switchgear takes up significantly less room than its air-insulated counterparts. Enclosed, environmentally tolerant and ideal for facilities where space is at a premium.

The end result? Fulfillment centers have more space to pack on power capacity — and less space tied up with operations.

Pretty smart, right?

Automation Is Changing The Power Game

Robots don’t take breaks.

They just keep consuming energy. And that’s the challenge every fulfillment center faces these days.

Consider these statistics: industry data shows globally there were more than 450,000 units of logistics robots sold in 2025 versus 75,000 units in 2019, an increase of 500%. Every single one of those robots requires energy to charge up, function, and communicate.

Here’s what automation adds to the electrical load:

• AMRs (autonomous mobile robots) constantly cycling on charging stations

• AS/RS systems moving pallets at high speed

• Robotic arms for picking and packing orders

• Advanced sortation systems running non-stop

In some plants, electrical demand has doubled as a result of implementing automation. Keep in mind that your electrical system should expand along with your automation efforts.

Skip that step, and the whole system fails. Simple as that.

Smart Load Management Strategies

Expansion isn’t the only solution. Intelligent distribution centers are also getting way smarter about how they handle capacity.

What does that look like in practice?

• Load balancing across multiple circuits to prevent overloads

• Peak shaving to reduce demand charges from the utility

• Real-time monitoring to spot problems before they cause downtime

• Smart controls that shift non-critical loads to off-peak hours

Load management systems work by software continuously measuring how much load each portion of the facility is pulling. Once one area nears capacity the system will automatically balance itself.

Cool, right?

Installations like this can cost fulfillment centers thousands less per month on demand charges. They also safeguard equipment from spikes and prolong expensive electrical equipment.

Renewable Energy & Backup Systems

Fulfillment centers are getting eco-friendly too. Makes perfect sense when you consider the square footage of roof real estate these buildings have.

Some are adding:

• Solar panels across giant rooftops

• On-site battery storage systems

• Wind power in certain regions

• Combined heat and power (CHP) setups

Solar energy is particularly common. One fulfillment center can have enough panels to cover a large percentage of its energy usage during the day.

But renewables alone aren’t enough. Every facility still needs solid backup power. That means:

• Diesel or natural gas generators

• UPS (uninterruptible power supply) systems

• Automatic transfer switches

These systems automatically activate when the grid fails, typically within seconds. Seconds matter to fulfillment centers that have strict shipping windows.

Notice how backup systems only function to the extent that their switchgear allows. Switchgear that is undersized or outmoded can strangle the best backup plan. So carefully consider any existing electrical infrastructure before investing. Upgrading your core equipment almost always precedes renewable additions.

The Bigger Picture

There’s one more piece to this puzzle…

Even utilities companies are behind the curve. Adding additional power to your fulfillment center likely means working with your local utility to upgrade the grid, transformers and yes … the substation serving the facility.

It can take months. Even years. So operators who plan ahead are the ones who dodge painful delays later.

Smart planning includes:

• Load forecasting for the next 5-10 years

• Working with utilities early

• Choosing scalable electrical infrastructure

• Building in redundancy from day one

Winning fulfillment centers view power as an investment, rather than a cost center.

The Bottom Line

Fulfillment centers are under pressure like never before. Increased orders. Increased robots. Increased automation. And yep — a lot more electricity.

The facilities that can handle these demands are the ones future-proofing their electrical infrastructure today rather than tomorrow. This includes hardening utility substation switchgear, installing intelligent load shedding and incorporating inherent redundancies.

To quickly recap:

• Energy demand at fulfillment centers is growing fast

• Modern switchgear is smaller, safer, and more reliable

• Automation adds huge electrical loads that need real planning

• Smart load management saves money and prevents downtime

• Renewables and backups round out the whole strategy

Who’s gonna get left behind? Centers that don’t pay attention to this. Right now? They’re investing, tomorrow they’re shipping. Everybody else is playing catch-up.

The choice really is that simple.
