Transforming Energy Management: The Rise of Virtual Power Plants

August 29, 2023

What is a Virtual Power Plant?

A Virtual Power Plant (VPP) combines a multitude of small-scale energy resources into a larger, coordinated entity. This aggregation allows for efficient management and control of these resources as a single system.


VPPs connect and control the energy created and stored by hundreds or thousands of individual distributed energy resources (DERs) like solar panels, wind turbines, battery storage systems, electric vehicles (EVs) and more. When small-scale energy resources from households and businesses bundle together and function as a single unit, they can optimize the distribution of electricity in real-time to enhance energy efficiency, reliability, and grid stability.


Therefore, unlike traditional power plants that are centralized and often consist of a single large facility that sends energy out to everyone. VPPs are the reverse, where individual households and businesses each give their approval to participate in a network.


“Energy experts say they [VPPs] are key to reducing the power industry’s dependence on climate-damaging fossil fuels as the nation moves toward electrifying transportation, buildings, and industrial sectors,” Reuters

Key characteristics of a Virtual Power Plant include:


Remote Control: VPPs utilize advanced digital technologies, communication networks, and control systems to manage and optimize the performance of distributed resources remotely.


Grid Support: VPPs can provide services to the grid, such as peak shaving (reducing energy consumption during peak demand times), load balancing, frequency regulation, and voltage control. This helps enhance grid stability and reliability.


Dynamic Optimization: Through real-time monitoring and data analysis, VPPs can optimize the use of resources based on energy demand, supply availability, electricity prices, and grid stability conditions.


“If prices start to spike [or energy supplies are constrained] we can look and say ‘hey, we have a resource within this region’ and we can press a button and call on that resource,” said Reg Rudolph, chief energy innovations officer for the Tri-State Generation Association, Utility Dive.


Energy Market Participation: Some VPPs can participate in energy markets, selling excess power generated by distributed resources or providing grid support services for financial incentives.


Renewable Integration: VPPs facilitate the integration of renewable energy sources like solar and wind into the grid by managing their intermittency and variability.


Demand Response: VPPs can also incorporate demand response strategies, where energy consumption is adjusted in response to signals from the grid operator, helping to balance supply and demand. For example, if it’s a cloudy day and there’s not enough sunshine to generate the needed amount of power from solar panels, then grid stress can be relieved by homeowners reducing their HVAC usage.


“Last summer, California’s record-breaking, grid-straining heat wave forced the state government to send text messages asking residents for emergency, voluntary energy conservation. And it worked. Energy demand dropped; blackouts were avoided,” RMI.


VPPs contribute to a more resilient, sustainable, and efficient energy system by optimizing the use of distributed resources and reducing the need for centralized, fossil-fuel-based power plants. As technology advances and the energy landscape evolves, Virtual Power Plants are becoming increasingly important in shaping the future of energy management and grid stability.

What can we do to help now?

“Several utilities are finding ways to encourage VPPs. The Sacramento Municipal Utility District, for example, provides a subsidy for anyone with battery storage who wants to join a virtual power plant,” said Severin Borenstein, faculty director of the Energy Institute at the Haas School of Business at the University of California, Berkeley. Homeowners with DERs can check with their utility company about potential incentives for participation. 


Homeowners can effortlessly utilize Powerley’s mobile and web tools to monitor their energy generation, including solar, and seamlessly reintegrate it into the grid. Collaborating closely with utilities, Powerley pioneers inventive solutions that directly link to smart meters, offering an immediate view of energy consumption and valuable insights. Through our comprehensive suite of energy management tools, we actively foster the emergence of Virtual Power Plants, empowering utilities to enhance current infrastructure. This, in turn, drives the reshaping and redistribution of residential energy load, facilitates the transition to renewable sources, and vigorously advances the journey towards electrification.
