Virtual Power Plants (VPPs) are cloud-based energy management systems that aggregate many small and diverse distributed energy resources (DERs) – such as rooftop solar, batteries, combined heat and power (CHP) units, electric vehicles and flexible loads – and operate them collectively as if they were a single power plant. Through aggregation and coordinated control, these otherwise dispersed assets can provide grid services, participate in energy and ancillary markets and deliver demand-response capabilities that individual resources cannot access on their own.  

By pooling assets and optimizing their dispatch, a VPP can respond to real-time grid conditions, support the integration of variable renewable generation and contribute to system balancing. Aggregated operation enables frequency regulation, peak-period capacity provision and improved supply–demand alignment, while allowing owners of individual DERs to receive compensation for services traditionally delivered by centralized generation. 

Main outcomes of the solution 

• Sustainability: Supports higher renewable penetration by coordinating distributed solar, storage and flexible loads into a responsive aggregated asset that can absorb, store or export energy as system conditions require. 
• Reliability & Flexibility: Improves system stability by enabling aggregated DERs to provide balancing, frequency regulation and peak-shaving services through real-time coordination. 
• Business Value: Enables smaller DER owners to access energy and ancillary-service markets that typically require scale, lowering participation barriers and creating additional revenue streams for asset owners, aggregators and utilities. 

Key deployment and scaling factors 

1. Establish DER registration frameworks that allow residential, commercial and industrial resources to enroll in VPP programs. 
2. Deploy secure communication and control infrastructure linking aggregated DERs to a central dispatch platform. 
3. Enable market-access mechanisms that allow VPPs to participate in energy, ancillary and, where applicable, capacity markets. 
4. Design incentive structures such as rebates, dynamic tariffs or revenue-sharing arrangements to encourage participation. 
5. Ensure regulatory recognition of aggregated resources as eligible providers of grid services. 

Case Study

Next Kraftwerke and Peleman Industries (2023), Germany

Peleman Industries first explored installing a BESS alongside a wind turbine to store surplus generation and increase operational flexibility, but on-site use alone did not generate sufficient revenue to justify the investment. To secure a more reliable income stream, Peleman Industries joined the Next Pool VPP, which aggregates distributed batteries to qualify for the Frequency Containment Reserve (FCR) market. Through digital aggregation, Next Kraftwerke links multiple units into a single flexible resource capable of responding within seconds to frequency deviations. The VPP sends automated control signals that direct charging and discharging in real time, enabling precise grid-stabilisation services. Aggregation also helps small storage units meet strict FCR performance and minimum-capacity requirements. By managing forecasting, real-time monitoring, market bidding and technical compliance, Next Kraftwerke enables battery owners to access ancillary-service revenues while contributing to system stability.
