Front-of-the-Meter vs. Behind-the-Meter
Key Differences
Front-of-the-Meter and Behind-the-Meter energy solutions are not the same. The biggest difference is where each connects to the power grid. Front-of-the-Meter systems are on the utility side of the meter. These systems help the whole grid and many people at once. Behind-the-Meter systems are on the customer’s side of the meter. These systems help just one home or business. They let users control their own energy.
The table below shows how they are different in technical and operational ways:
Feature | Front-of-the-Meter (FTM) | Behind-the-Meter (BTM) |
|---|---|---|
Location | Utility side of the meter | Customer side of the meter |
Management | Managed by the utility | Managed by the customer |
Purpose | Supports the grid | Serves the customer’s needs |
Size | Large, centralized | Small, often residential |
Integration | Part of the utility network | Works on the customer’s property |
Benefits | Keeps grid reliable | Lowers bills, gives backup power |
Front-of-the-Meter systems send power right to the grid. Behind-the-Meter systems make or store energy for use at the building.
Location and Scale
Where the system is and how big it is makes a difference. Front-of-the-Meter projects are usually not at the customer’s site. Utilities build them on big land or large rooftops. These projects can be huge, even hundreds of megawatts or gigawatts. They serve whole cities or regions.
Behind-the-Meter systems are much smaller. People put them on homes, schools, or businesses. These systems are usually just a few kilowatts or megawatts. They only help the building where they are set up.
Here is a quick comparison:
Feature | Behind-the-Meter (BTM) | Front-of-the-Meter (FTM) |
|---|---|---|
Location | On-site | Off-site, utility-side |
Scale | kW–MW (small to medium) | MW–GW (large to very large) |
Front-of-the-Meter projects often cost less for each unit of energy because they are bigger. They can also help the grid during busy times.
Revenue and Ownership
Front-of-the-Meter and Behind-the-Meter systems make money in different ways and have different owners. Utilities or big companies usually own Front-of-the-Meter systems. They sell electricity to the grid or other utilities. They often use long-term deals called power purchase agreements.
Behind-the-Meter systems are usually owned by the people or businesses who use them. Sometimes, another company owns the system and sells power to the people in the building. These systems help owners save money on energy bills. Sometimes, they can sell extra power back to the grid.
The table below shows the main differences:
Model Type | Ownership | Revenue Model |
|---|---|---|
Front-of-the-Meter | Utilities or large companies | Sell electricity to grid under PPAs or contracts |
Behind-the-Meter | Individuals, businesses, or third parties | Save on bills, sell power to tenants or the grid |
Front-of-the-Meter and Behind-the-Meter solutions give different benefits to owners. Utilities use Front-of-the-Meter projects to help the grid and make money from selling power. Homeowners and businesses use Behind-the-Meter systems to lower their costs and have more control over their energy.
Use Cases
FTM Examples
Front-of-the-Meter energy solutions are used in big projects. These projects give power to lots of people. Utilities and energy companies build these systems. They help the grid and serve whole towns.
In Iowa, seven schools, hospitals, and businesses use wind turbines. The turbines are between 225 kW and 660 kW. Together, they make over 3 MW of power.
Nineteen other customers use smaller turbines under 100 kW. These small turbines add up to 665 kW.
There are plans for at least 2 MW more in big wind turbines. Some projects are delayed because of legal problems.
Big commercial customers, factories, data centers, and hospitals use FTM systems. These groups need steady and strong power for their work. They pick FTM solutions because these systems give lots of energy. FTM systems also help keep the grid working well.
BTM Examples
Behind-the-Meter energy solutions help single buildings or places. Homeowners, small businesses, and groups use these systems. They use them to control their own energy.
A warehouse uses a battery to store cheap power at night. The warehouse uses this power to charge electric vehicles during the day. This helps lower demand charges.
An airport uses a battery for backup power when the lights go out. The battery also helps with daily spikes in energy use. This keeps things running smoothly.
Stores put batteries in many locations. These batteries help lower energy costs. They also help the company reach its sustainability goals.
