VPP Explained: What Is a Virtual Power Plant?

Industry insights · Apr 13, 2023


Virtual Power Plants (VPPs) are cloud-based system that integrates multiple power sources together to provide a more reliable overall power supply. VPPs are comprised of Distributed Energy Resources (DERs) power generation, trading and/or selling power in the electricity market, and demand side options for load reduction. Common DERs found in VPPs include photovoltaic solar, stationary energy storage, electric vehicle chargers, and demand-responsive devices such as water heaters, thermostats, and large home appliances

The concept of VPPs emerged in the early 2000s and has since become a promising solution to the aging electrical infrastructure across North America. By pooling multiple DERs, VPPs can provide a reliable and stable electricity supply while offering benefits such as improved grid stability, reduced energy costs, and lowered carbon emissions. However, renewable energy resources are, by nature, intermittent hence why the importance of energy storage plays a critical role in the success of VPPs.

Advantages of VPPs

VPPs provide value to all shareholders of the electric grid. Utilities, ratepayers, and everyone in between can benefit from the values derived from VPP applications.

One of the primary advantages of VPPs is their ability to balance the variability of renewable energy sources. Solar and wind energy can be unpredictable, with output varying depending on weather conditions and time of day. By combining multiple energy sources into a single system, VPPs can balance the fluctuations and provide a more consistent energy supply.

VPPs also offer a range of benefits for energy consumers. Consumers who participate in VPPs can also benefit from reduced energy costs, as the VPP as the VPP shares energy locally, reducing the need to purchase energy from the utilities and minimizing the impact of outages from the increasingly fragile, long-distance utility grid.

Furthermore, VPPs can improve grid stability and reduce the likelihood of blackouts. By integrating multiple energy sources into the grid, VPPs can respond to changes in energy demand and supply in real time, helping to balance the grid and prevent overloading. This is particularly important in regions with high penetration of renewable energy sources, where traditional grid infrastructure may struggle to cope with fluctuations in energy supply.

According to Rocky Mountain Institute, a non-profit organization, estimates that by 2050, VPPs could displace 44–59 million metric tons of CO2 being produced each year. VPPs bring renewable energy resources to the existing electric grid and immediately lessen our dependency on fossil fuel energy resources.

Additionally, VPPs will integrate electric vehicle batteries by allowing them to discharge their stored energy onto the grid, where and when needed.

VPP Disadvantages

Despite the numerous advantages of VPPs, there are also challenges to their widespread adoption.

One major challenge is the lack of standardization in VPP technology and regulations. As VPPs are still a relatively new concept, there is currently no widely accepted standard for VPPs, and regulations can vary widely between different regions and countries. This lack of standardization can make it difficult for energy producers and consumers to participate in VPPs and can limit the potential benefits of the technology.

Another challenge is the need for advanced software and hardware systems to manage the complex interactions between different energy sources in a VPP. This requires significant investment in technology and infrastructure, which can be a barrier to entry for smaller energy producers.

Furthermore, there are concerns about data privacy and cybersecurity in VPPs. As VPPs rely on a centralized control system to manage energy distribution, there is potential for cyber-attacks that could compromise the security of the energy system. Additionally, as VPPs require collecting and sharing large amounts of data, there are concerns about data privacy and the potential misuse of consumer data.


Despite these challenges, the potential benefits of VPPs make them a promising solution for integrating renewable energy sources into the grid. As technology and regulations continue to evolve, it is likely that VPPs will be a necessary supplement for the grid system, comprising an indispensable part of the renewable energy map.
