Take Control of Your Energy and Save some Money in the Process
Whole home battery backup systems can do more than just keep your lights on during a power outage—they can also help save you money on your energy bills through strategies like time-of-use (TOU) management and peak shaving. Let's dive into how these concepts work and explore other ways these batteries can bring savings.
1. Time-of-Use (TOU) Management
Many utilities, including some in Missouri like Evergy, use time-of-use (TOU) rates, which means the cost of electricity varies depending on the time of day. Rates are typically higher during peak hours (times of high demand, often in the late afternoon or evening) and lower during off-peak hours (typically overnight and midday when demand is lower).
With a whole home battery backup system, you can:
Store energy when rates are cheap: Your battery can be charged during off-peak times when electricity rates are lower.
Use stored energy during peak hours: Instead of drawing power from the grid when rates are highest, you can use the energy stored in your battery, effectively avoiding the most expensive rates and reducing your utility bill.
2. Peak Shaving
Peak shaving is another money-saving technique enabled by whole home batteries. Here’s how it works:
During times of peak electricity demand (like hot summer afternoons), utilities may charge extra for the energy you use. With a battery, you can "shave off" these peaks by drawing power from the battery rather than the grid during those high-cost periods. This not only saves you money but can also reduce the demand charges for homes that have them (though demand charges are more common in commercial billing).
3. Solar Integration for Extra Savings
If you have (or are considering) a solar panel system, combining it with a whole home battery can amplify your savings.
Solar panels generate electricity during the day, and excess power can be stored in the battery rather than being sent back to the grid at lower compensation rates.
This stored solar energy can then be used at night or during peak TOU periods, reducing the amount of energy you need to buy from the utility at higher rates.
4. Backup Power and Avoiding Outages
Whole home battery systems like the Tesla Powerwall also provide backup power in case of grid outages. While this doesn’t directly save money during normal operation, it helps avoid the costs associated with power loss, such as spoiled food, lost work productivity, or maintaining other backup systems like generators.
5. Leveraging Utility Incentives and Demand Response Programs
Some utilities offer incentives or rebates for installing whole home battery systems, or they may provide compensation if you allow them to use your battery as part of a demand response program. During high electricity demand events, the utility can draw on stored energy in participating batteries to stabilize the grid, and in return, homeowners get paid or receive discounts.
6. Self-Consumption Optimization...OK there are Six
Batteries can help you maximize self-consumption of the energy you produce. Rather than selling excess solar power back to the grid at a low feed-in tariff rate, you store it and use it later, effectively getting more value for the energy you produce.
Summary of Savings Strategies: Ways Whole Home Battery Backup can save you money
TOU Management: Charge when rates are low, discharge when rates are high.
Peak Shaving: Use battery power during the most expensive demand periods.
Solar Integration: Store excess solar for use when rates are highest.
Backup Power: Save on the costs of potential outages.
Utility Incentives: Take advantage of rebates, incentives, and demand response.
Self-Consumption: Use stored solar energy later for more financial benefit.
These strategies can be combined for significant long-term savings, especially when energy costs fluctuate or are expected to rise. Whole home battery backup systems, particularly in areas with TOU pricing and solar incentives, can provide both energy security and a smart way to reduce energy costs.
