Load management is the smart way to get whole-home generator coverage without paying for an oversized generator. Instead of buying a generator large enough to run every appliance in your home simultaneously, a load management system automatically cycles large loads on and off to keep the total demand within your generator's capacity. The result: every circuit in your home has access to power, but not all at the same instant. Unity Power & Light installs load management systems for new and existing generators throughout Aiken, SC.

Load management can save you $3,000 to $5,000 on generator equipment costs by allowing a smaller generator to cover your entire home. For many homeowners, the brief, automatic cycling of non-critical loads is invisible in daily use, making load management one of the best values in backup power.

How Load Management Works

Continuous Monitoring

The load management system monitors the generator's output in real time, tracking exactly how many amps are being drawn. When the total load approaches the generator's rated capacity, the system prepares to shed lower-priority circuits to prevent overload.

Priority-Based Control

Circuits are assigned priority levels during installation. Essential circuits like refrigeration, lighting, and medical equipment are always on. Large loads like the AC compressor, water heater, and dryer are managed. When capacity is tight, lower-priority loads are temporarily disconnected. When capacity frees up, they reconnect automatically.

Automatic Operation

The entire process is automatic. You do not need to decide what to turn off or manually manage your power usage. The system makes intelligent decisions in real time based on actual load measurements, not guesswork.

Overload Prevention

Without load management, running too many large loads simultaneously can trip the generator's overload protection and shut it down entirely. Load management prevents this by proactively shedding loads before the generator reaches its limit, keeping the power on for everything that matters most.

Which Circuits to Prioritize

We work with you to establish the right priority levels for your household. Here is a typical prioritization for Aiken homes:

Always On: Refrigerator, freezer, essential lighting, security system, medical equipment, well pump, sump pump, internet/WiFi, HVAC blower fan

Managed (High Priority): HVAC compressor (air conditioner or heat pump). Managed because its startup surge is the largest single load, but it runs most of the time

Managed (Medium Priority): Electric water heater, kitchen range/oven. These can be shed for short periods without noticeable impact

Managed (Low Priority): Electric clothes dryer, pool pump, EV charger, spare room circuits. These are the first to be shed and last to be restored

Priorities are fully customizable and can be adjusted after installation based on your real-world experience during outages.

The Value Proposition

Here is a real-world example of how load management saves money:

Without load management: A 2,500 sq ft Aiken home with 3-ton AC, electric water heater, and electric range needs a 22kW generator for whole-home coverage. Installed cost: approximately $10,000 to $13,000

With load management: The same home can use a 14-16kW generator with load management modules. The generator powers every circuit but manages the AC compressor, water heater, and range so they do not all run simultaneously. Installed cost: approximately $7,000 to $9,000

Savings: $3,000 to $4,000 in equipment cost, plus lower fuel consumption during operation and reduced maintenance costs over the generator's lifetime

The trade-off is minimal. During an outage, you might notice your water heater takes slightly longer to recover because it was temporarily shed while the AC compressor was starting. Most homeowners never notice the load management cycling at all.

Pricing

Load management modules (per circuit): $150 - $300 installed per managed circuit

Typical 4-circuit load management system: $600 - $1,200 installed

Load management with new generator installation: Often bundled at reduced cost as part of a complete system

Load management added to existing generator: $800 - $1,500 depending on the number of circuits and generator compatibility
