Behind-the-Meter Distributed Energy Resources (DERs) are energy generation, storage, or management systems that are located on the consumer side of the electric meter, typically at or near the point of energy consumption. They are also known as customer-sited or on-site generation resources. These resources can generate, store, and manage electricity, heat, or other forms of energy, and are typically installed on residential, commercial, or industrial properties.
Examples of Behind-the-Meter Distributed Energy Resources include:
- Solar Photovoltaic (PV) Systems: These systems use solar panels to convert sunlight into electricity, which can be used on-site to power the property or stored in batteries for later use.
- Energy Storage Systems: These systems store excess electricity generated by other sources, such as solar PV systems or during off-peak times, and release it during peak demand periods to reduce electricity costs or provide backup power during grid outages.
- Combined Heat and Power (CHP) Systems: Also known as cogeneration systems, CHP systems generate both electricity and useful heat for on-site use, such as in industrial processes or for heating and cooling buildings.
- Microturbines and Fuel Cells: These are compact power generation systems that can provide electricity and heat on-site, using natural gas, biogas, or hydrogen as fuel.
- Energy Management Systems: These systems use advanced technologies, such as demand response, load control, and energy monitoring and management, to optimize energy use and reduce consumption during peak demand periods, thereby lowering energy costs and improving energy efficiency.
Behind-the-Meter DERs can provide a range of benefits, including increased energy efficiency, reduced energy costs, improved resiliency and reliability of energy supply, reduced greenhouse gas emissions, and increased local energy generation and self-consumption. They are often used by consumers, businesses, and industries to manage their energy needs, reduce their reliance on the grid, and contribute to sustainability and environmental goals. However, the installation, operation, and integration of Behind-the-Meter DERs may be subject to local regulations, utility policies, and technical considerations, and it’s important to consult with qualified professionals and adhere to applicable guidelines and standards.
