Time-of-Use & Bill Management

Store energy when it’s cheap, use it when it’s expensive — and reduce peak charges without changing how you live.

In many states, utilities charge different rates depending on when you use electricity. These time-of-use (TOU) pricing plans can lead to high bills — especially during peak hours in the late afternoon and evening. With a Fortress Power battery system, you can store energy when it’s cheap and use it when rates spike, saving money without sacrificing comfort.

Cómo funciona

Fortress Power batteries charge during off-peak hours — typically when solar production is high or utility rates are low. When peak pricing kicks in, your system automatically discharges stored energy to power your home, reducing or even eliminating expensive grid usage during those high-cost windows.

It’s a smart, automatic way to control your costs and get the most from your solar setup.

Where Time-of-Use (TOU) Pricing Applies

Time-of-use pricing is increasingly common in states like California, Arizona, Massachusetts, and New York, where utilities are shifting toward demand-based billing. If your utility charges TOU rate, you may be paying 2-3 times more for the electricity that you consume during the peak hours.

Even if you don’t have TOU yet, many utilities are expected to adopt it as the grid evolves.

Battery storage gives you a long-term hedge against rising and variable electricity rates.

Benefits of Fortress Power for TOU Savings

Automatically shift usage from high-rate to low-rate periods

Pair with solar for full self-generation during peak hours

Lower your monthly bill without changing your energy habits

Add resilience with backup power during outages

Compatible with utility incentive and VPP programs in select areas

Extend the value of your solar system by using stored energy after sunset

When paired with smart system design and utility program participation, Fortress Power batteries give you the flexibility to not just survive TOU billing — but turn it into a financial advantage.

How Fortress Power Compares to Other Backup Solutions

Not all backup power is created equal. While traditional generators and older battery technologies offer some protection during outages, they come with limitations — from noise and maintenance to short lifespans and safety concerns. Fortress Power’s lithium iron phosphate (LFP) systems deliver clean, reliable, and long-lasting energy you can count on — with fewer compromises and more control.
