BTM – Behind-the-Meter

BTM stands for Behind the Meter and describes energy systems that are installed behind a company’s grid connection point. These include, for example, battery storage systems, photovoltaic systems or energy management systems.

The meaning of Behind the Meter

Because BTM systems are operated behind the electricity meter, they directly influence a site’s electricity consumption. As a result, companies can reduce their grid consumption, optimise load profiles and lower energy costs.

Typical applications

Behind-the-meter systems are frequently used in industry and commerce for:

• Peak shaving to reduce grid fees
• Self-consumption optimisation for photovoltaic systems
• Integration of PV systems with storage
• Optimising charging infrastructure

Distinction from Front of the Meter

The counterpart to Behind the Meter is Front of the Meter (FTM). While BTM systems are installed directly at the consumer’s premises, FTM installations are operated at grid level and often serve electricity market participation or grid stabilisation.

Frequently Asked Questions (FAQs)

What does Behind the Meter (BTM) mean?

Behind the Meter refers to energy systems that are installed behind a company’s grid connection point and directly influence on-site electricity consumption.

Which installations typically belong to BTM systems?

Typical behind-the-meter systems are battery storage systems, photovoltaic systems, energy management systems and charging infrastructure operated within a company site.

How does BTM help to optimise energy costs?

BTM systems can reduce peak loads, increase self-consumption and optimise grid consumption, which can lower grid fees and electricity costs.

How does BTM differ from Front of the Meter?

Behind the Meter describes installations behind a consumer’s grid connection point, whereas Front of the Meter installations are operated directly within the electricity grid.

What role do battery storage systems play in BTM systems?

Battery storage systems are central components of BTM systems, as they can buffer electricity, smooth load profiles and increase the self-consumption of renewable energy.
