Understanding the energy transition: How virtual power plants and direct marketing work together
Energy industry in transition: Why virtual power plants are driving the energy transition
Virtual power plants and the direct marketing of electricity are two central elements of the modern energy industry that are closely intertwined but pursue different functions and objectives. While virtual power plants represent a technological platform for efficiently coordinating the generation and use of renewable energies, direct marketing focuses on profitably placing the generated energy on the energy markets. This text examines both concepts in detail, describes their role in the energy industry, and demonstrates their significance for the energy transition.
Virtual power plants – The digital transformation of energy supply
A virtual power plant (VPP) is a network of decentralized energy generation facilities, storage systems, and consumers that are digitally interconnected and coordinated via a central control system. These facilities include, among others, wind and solar power plants, biomass power plants, battery storage systems, and flexible industrial or residential consumers. The goal of a virtual power plant is to increase the efficiency and flexibility of energy generation and consumption by treating and controlling the various facilities as a single unit.
Through digitalization and automation, a virtual power plant enables precise forecasting and planning of energy generation and consumption. This allows for the minimization of over- and underproduction and the stabilization of the energy supply. Virtual power plants play a key role not only in the balancing energy market – where they compensate for fluctuations in the electricity grid – but also in the spot market, where electricity is traded on a short-term basis.

Direct marketing – From the EEG to market integration
Direct marketing refers to the sale of electricity from renewable energy sources directly on the electricity exchange or to large consumers, instead of via fixed feed-in tariffs as granted under the Renewable Energy Sources Act (EEG). It was introduced as a tool to promote the market integration of renewable energies and to allow operators of such plants to participate more fully in market price developments.
Since the reform of the German Renewable Energy Sources Act (EEG) in 2016, direct marketing has been mandatory for all new installations with a capacity exceeding 100 kW. This has led to an increasing number of operators switching from fixed feed-in tariffs to flexible, market-oriented revenue streams. Direct marketing offers operators the opportunity to profit from high market prices, but also carries risks associated with price fluctuations. This dynamic environment necessitates a thorough understanding of market mechanisms and access to specialized trading platforms.
Synergies between virtual power plants and direct marketing
Virtual power plants and direct marketing complement each other perfectly, as they perform different but mutually supportive functions. A virtual power plant serves as a platform where various small energy producers and consumers can be bundled and coordinated. This creates a larger player in the market that can operate competitively without each individual operator needing in-depth market knowledge.
By using a virtual power plant, smaller operators gain access to direct marketing, which would otherwise be difficult for them to access due to technical and organizational requirements. Furthermore, pooling resources in a virtual power plant offers the advantage of balancing fluctuations in the production of individual plants, thus improving market position and revenue stability.
Advantages and challenges of virtual power plants
Advantages
- Increased efficiency: Intelligent control minimizes energy losses and optimizes the utilization of the systems.
- Market access for small operators: Operators of small plants benefit from joint marketing without having to actively participate in the energy market themselves.
- Flexibility: Virtual power plants can react quickly to fluctuations in energy demand and production.
- Supporting the energy transition: By integrating renewable energies, virtual power plants make an important contribution to the decarbonization of the energy sector.
challenges
- Technological requirements: Operating a virtual power plant requires a complex IT infrastructure and reliable data connections.
- Regulatory requirements: Compliance with legal provisions and market regulations presents a hurdle, especially for smaller operators.
- Economic risks: Fluctuating market prices and dependence on support mechanisms such as the EEG (Renewable Energy Sources Act) can impair profitability.
Comparison to other models
feed-in tariff
This traditional model offers operators a fixed payment for the electricity fed into the grid, ensuring planning security. However, operators cannot benefit from market price increases under this model.
Direct marketing
Compared to feed-in tariffs, direct marketing offers the opportunity to benefit from flexible market prices. However, it requires active market participation and cooperation with direct marketers.
Virtual power plants
They combine the advantages of both models: the stability and planning security of pooling, as well as the opportunity to benefit from market-oriented prices. This represents an ideal solution, particularly for small plant operators, to remain competitive.
Key building blocks for a sustainable energy future
Virtual power plants and direct marketing are key building blocks for a sustainable energy future. They enable the efficient use of renewable energies and promote their integration into the energy market. With increasing digitalization and rising demands on grid stability, virtual power plants will continue to grow in importance.
Both concepts are essential for the energy transition. While direct marketing strengthens the economic viability of renewable energies, virtual power plants contribute to ensuring security of supply in a decentralized energy system. Together, they create the foundation for a sustainable and resilient energy system of the future.
