Power outages are no longer a question of “if” but “when.” They are becoming more frequent, severe and prolonged due to climate change, aging electrical grids, retiring power plants and surging energy demand.
For example, U.S. electricity customers had to deal with up to about 13 hours of electricity interruptions, nearly double the previous decade’s annual average. And over the past two decades, 80% of all major power outages were due to weather, primarily from severe weather and winter storms.
For construction companies, manufacturing facilities and service operations, even a short outage can be costly and dangerous.
In this article, you’ll learn how to handle a worksite power outage, including what equipment can provide temporary power for construction sites. Working with a trusted equipment rental provider, like Herc Rentals, ensures access to the equipment, support and expertise needed to mitigate the next business or worksite power outage.
How Power Outages Can Derail Your Worksite
When the lights suddenly go out, work stops. Crews stand idle, equipment stops running, emergency batteries start beeping. Every minute of downtime costs money. Safety risks also increase as workers are left in the dark, creating hazards across the site.
You need to have a clear plan, assemble an emergency team with designated leaders, and know who to contact and when.
Start planning early. First research your local laws about power outages at work. Resources to help develop a plan are available from organizations like the Federal Emergency Management Agency (FEMA).
Then, contact your trusted equipment rental provider. They can help you assess your site and make sure you’ll have the right backup power equipment for your facility. They may also offer safety training and other resources to make sure your teams know how to safely operate equipment in a variety of conditions.
Following step-by-step procedures allows work to resume safely and efficiently, minimizing downtime and keeping projects on track.
What to Do Immediately When a Power Outage Hits Your Worksite
With a solid plan, you can minimize the disruption of an outage and keep employees and equipment safe. When the power goes out, take these steps right away.
1. Prioritize Safety
Account for everyone on site. Safety leaders should check their assigned areas, perform a headcount and initiate evacuation procedures if necessary. Activate communication trees and mass-notification systems so information flows quickly and accurately.
2. Secure Your Equipment
Protect sensitive machinery from damage. The energy leader should guide controlled shutdowns, verify equipment is powered off safely and confirm surge-vulnerable systems are disconnected or stabilized to reduce risk once power returns.
3. Assess the Situation
Determine the extent of the outage. Is it limited to your facility or project site? Do neighboring businesses still have power? If the issue appears isolated, contact your on-call electrician and utility provider.
4. Report Issues to the Utility Company
Have your designated staff member report the outage — don’t assume someone else already has. Request an estimated restoration time to direct the next steps, including whether to activate backup power. If you encounter downed power lines, call 911 immediately.
5. Call a Reliable Equipment Rental Provider While You Wait
If restoration is expected to take some time or operations cannot stop, contact your equipment rental provider for temporary generators and other essential gear, like lighting or climate control solutions.
Because working with power is inherently dangerous, only trained personnel should install and manage temporary power systems. Your equipment provider should be familiar with OSHA power outage laws and requirements for grounding, GFCI protection, ventilation and proper installation. Partnering with a professional rental service ensures compliance, reduces risk and keeps your project moving.
5 Solutions to Get Your Worksite Up and Running
Preparation is key to reducing downtime during an outage. These five solutions can help you stay ready, keep your team safe and maintain operations when the unexpected happens.
1. Implement a Backup Power Plan
A well-crafted backup power plan lets your team act immediately — without guessing — when the lights go out. At its core, the plan should spell out what facets need power, how it will be supplied and who is responsible for each step.
Make sure your backup power plan includes:
- List of Critical Equipment and Their Power Requirements: Identify your site’s most critical equipment, such as emergency lighting, communications, safety systems and machinery. Then document your construction site’s temporary electrical distribution needs. This means finding out how much load your equipment will need and where power needs to go.
- Backup Power Sources: Determine if portable generators, towable units, battery systems or a combination are needed.
- Startup and Shutdown Protocols: Provide step-by-step instructions and designate the trained personnel who will carry them out.
- Electrical Safety Requirements: Include grounding, GFCI protection, ventilation and all temporary-power standards.
- Fuel Storage: Include what types of fuel generators need, the quantities and safe storage practices.
- Communications Plan: Specify who will be notified when backup power is activated and how updates are shared.
- Maintenance and Testing: Set inspection schedules to ensure the system is always ready.
- Restoration Procedures: Determine how to transition equipment back to utility power and shut down temporary systems once power is restored.
2. Deploy Mobile Generator Rentals
Commercial-sized generators provide immediate, flexible power for trailers, equipment or your entire project site. Mobile generator rentals come in a variety of sizes and types from compact portable generators to heavy-duty industrial models. Towable generators can be easily moved, while skid-mounted models can be placed with a forklift.
Their versatility makes them ideal for construction sites, industrial facilities, medical facilities, data centers and remote locations. They are also perfect for planned utility outages and remote project sites where permanent power is unavailable.

3. Set Up Temporary Light Towers
Adequate lighting is critical for both safety and productivity, especially at night or in poor weather. Light towers illuminate work zones, walkways, parking areas and event sites, allowing teams to move safely and maintain operations.
They also strengthen site security during outages, which is when the risk of theft and vandalism typically increases. Generator-powered, solar or engine-driven lighting options means you’ll have the flexibility to keep the lights on in any emergency.
4. Use Portable Power for Smaller Needs
Small portable generators, battery packs and inverter units are ideal for powering individual tools, small work areas or isolated tasks. Lightweight and mobile, these units keep crews productive while larger systems come online. They are especially useful for fans, small pumps, chargers, lights and handheld tools.
5. Ensure Fuel and Maintenance Support
Don’t forget fuel and maintenance when estimating temporary power for construction site costs. Temporary power is only effective if the equipment has the fuel and service support necessary to keep it running. During widespread outages, fuel availability and the capacity to maintain equipment can become strained as demand spikes.
Calculate how much fuel your generators may need and make sure you have it ready to go.
A reliable provider offers refueling services, on-site maintenance, monitoring and 24/7 support to keep your equipment performing reliably and your worksite operational.
