The ABCs of VPPs: An Introduction to Virtual Power Plants
Adam Warren | Clean Energy States Alliance
This paper aims to help state officials and other stakeholders understand what virtual power plants (VPPs) are and how they can be optimally designed.
For state energy agencies, a central challenge is to help create the technical, regulatory, and programmatic conditions that allow VPPs to develop, access markets, and realize their potential as dependable grid resources.
The report answers the following questions:
- What is a virtual power plant?
- Why do VPPs matter now?
- Who participates in a VPP?
- What happens when a VPP is dispatched?
- What are the main technology layers in a VPP?
- What information is shared in a VPP?
- How do devices enrolled in VPPs communicate?
- What are standards, and why do they matter?
- What makes a VPP look less risky to utilities?
- What makes a VPP look less risky to participants and other ratepayers?
- What should state energy agencies ask when reviewing or developing a VPP program?
- What technical and institutional barriers still slow VPP deployment?
- What new developments should states monitor?
The main takeaways for state energy agencies are straightforward: VPP scale depends less on technology breakthroughs than on trusted communication among devices, customers, aggregators, utilities, markets, and regulators. Standards can reduce integration costs and make programs more repeatable. Embedding equity components in VPP program rollout and design can help ensure public support and widespread adoption. VPPs also need customer protections, cybersecurity plans, performance measurement, data governance, and compensation rules that are clear enough for customers, utilities, aggregators and market operators to rely on.
This report was produced by CESA as part of the VPP Acceleration Initiative. The Initiative helps states, local governments, communities, and financial institutions deploy and scale VPPs—advancing affordability, strengthening resilience and grid reliability, and supporting decarbonization. This initiative is led by CESA, Clean Energy Group (CEG), and World Resources Institute (WRI).
