The traditional electricity grid is undergoing a fundamental shift as distributed energy resources (DERs) like solar panels, batteries, and smart appliances proliferate. Virtual Power Plants (VPPs) are at the forefront of this transformation. A VPP is a cloud-based network that intelligently links DERs, allowing them to collectively function as a distributed power plant This can provide crucial grid services like frequency regulation and voltage support [1].
How Do VPPs Impact Customers?
VPPs open up new possibilities for customers both on an individual basis and collectively.
- Potential Cost Savings: VPPs allow customers to earn payments for making their energy resources accessible during peak times. This reduces reliance on costly fossil-fuel ‘peaker plants’, potentially lowering overall electricity bills [2].
- Resilience and Reliability: VPPs can dispatch backup power from DERs during outages, improving grid resilience for customers [2].
- Sustainability: VPPs promote the integration of renewables, reducing emissions and accelerating the clean energy transition [3].
- Choice and Flexibility: VPP programs offer more options for consumers to actively manage their energy production and consumption [3].
AEMO’s report on a Consumer Insights study from 2021 paints a picture of cautious optimism among consumers regarding VPPs. Participants generally enjoyed the potential economic benefits and the contribution to environmental sustainability. They appreciated the greater visibility into their energy usage and some level of control in their energy management. However, concerns did exist regarding the complexity of VPP programs.
Key takeaways from the study highlight the importance of clear communication and transparency from VPP providers. Consumers indicated their desire for easy-to-understand explanations about VPP technology, its operation, and the specific benefits for individual households. Building trust was seen as crucial, especially in ensuring consumers understand their continued ability to manage their energy assets and the absence of any negative implications for reliability. Educational initiatives and simplified contractual agreements will likely play significant roles as the VPP market matures and expands.
Customer Control and Energy Usage
Customers participating in VPPs typically retain ownership of their DERs. In a VPP, software optimizes usage for grid benefit. The specific amount of energy drawn from an asset like a home battery depends on contractual agreements, market conditions, and the homeowner’s preferences. Many VPPs allow customers to set limits or opt out of events if needed, offering a balance between flexibility and potential benefits [1].
The Evolving Future of VPPs
The growth of VPPs hinges on regulatory support, technological advancements, and consumer awareness. As these areas progress, VPPs promise greater consumer choice, cleaner energy, and a more resilient grid.
