DER aggregations, or Distributed Energy Resources aggregations, refer to the collective management and coordination of multiple small-scale, decentralized energy resources to provide grid services and meet specific energy needs. 

How did this all get started? Well, it started with FERC Order 2222, which was issued by the Federal Energy Regulatory Commission (FERC) in 2020. FERC Order 2222 aims to remove barriers and promote the participation of Distributed Energy Resources (DERs) in the wholesale electricity markets.

Under FERC Order 2222, DER aggregators are granted the opportunity to participate in wholesale markets, allowing them to aggregate and bid the combined capacity of multiple DERs into the market. This opens up new avenues for DERs, such as rooftop solar systems, energy storage systems, and demand response resources, to provide grid services, increase grid flexibility, and contribute to grid reliability.

Here's what you need to know about DER aggregations.

Definition of Distributed Energy Resources (DERs)

DERs encompass a wide range of small-scale, decentralized energy resources that are typically located close to the point of consumption. Examples include rooftop solar panels, energy storage systems, small wind turbines, electric vehicles (EVs), and demand response systems. DERs are often characterized by their ability to generate, store, or manage electricity at a local level.

Aggregation Concept

DER aggregation involves combining multiple individual DERs into a single entity or portfolio. This aggregation can be done through virtual power plants (VPPs), energy management systems, or advanced software platforms. By aggregating DERs, their combined capabilities and capacities can be harnessed and coordinated for more efficient and optimized energy management.

Benefits of DER Aggregations

Grid Support

DER aggregations can provide grid support services, such as frequency regulation, voltage control, and grid stability. By collectively responding to grid signals or operator commands, DER aggregations can enhance the reliability and flexibility of the electrical grid.

Demand Response

Aggregating DERs allows for demand response capabilities, enabling the reduction or shift of electricity consumption during peak demand periods. This helps alleviate stress on the grid and can provide economic benefits for customers through incentive programs.

Integration of Renewables

DER aggregations facilitate the integration of intermittent renewable energy sources into the grid. By pooling together various DERs, it becomes possible to smooth out variability and optimize renewable energy generation, increasing overall grid penetration of clean energy.

Energy Trading

Aggregated DERs can participate in energy markets and provide services such as energy arbitrage (buying and selling electricity at advantageous prices), ancillary services, or participation in wholesale energy markets. This enables DER owners to access additional revenue streams and enhance the overall value of their assets.

Technological Enablers

DER aggregations rely on advanced technologies and communication systems that facilitate real-time monitoring, control, and optimization of the aggregated resources. These technologies enable efficient coordination, data management, and decision-making to maximize the value and performance of DER aggregations.

Regulatory Frameworks

The regulatory landscape surrounding DER aggregations is evolving. Some regions have specific rules and frameworks to facilitate and govern the participation of aggregated DERs in energy markets. These regulations may address issues like compensation mechanisms, technical requirements, market access, and operational rules for aggregators.

The Power of DER Aggregations for a Decentralized and Sustainable Future

DER aggregations are gaining importance as a means to unlock the full potential of distributed energy resources and transform the electricity system into a more decentralized, efficient, and sustainable model. By effectively managing and coordinating DERs, aggregations can contribute to grid reliability, renewable energy integration, and more dynamic energy markets.
