How Virtual Power Plants (VPPs) Work and How You Can Decide If You Should Join

What happened

• A Virtual Power Plant (VPP) is a collection of household devices like smart thermostats, EV chargers, home batteries, and solar panels that a utility can control.
• Utilities use VPPs to command these devices to reduce electricity usage during peak hours, for example, by adjusting thermostats or delaying EV charging.
• In exchange for participation, utilities offer participants discounts on energy bills and sometimes signing bonuses.
• When scaled up, the collective impact of VPPs can be profound, equivalent to firing up a power plant when managing hundreds of thousands or millions of homes.
• As of 2023, there were over 500 VPP programs operating in the US alone, and 4 million households with smart thermostats were enrolled in a VPP program last year.

Why it matters for me

VPPs offer potential savings, especially from home batteries and EVs, but participation requires assessing your flexibility and understanding data privacy. While some programs can help utilities avoid expensive grid upgrades, you must ensure the system is implemented well to avoid unexpected bill increases.

What to remember

• Check if your utility company has a VPP program or look for related terms like ‘demand response’ or ‘peak rewards’ on their website.
• Eligibility rules vary widely based on device brands, location, and rate plans; check the fine print carefully before enrolling.
• Consider your personal flexibility: some households may not have the time or flexibility to engage fully in these programs.
• Review data usage: Be aware that these programs collect data about energy use, which could reveal private routines inside your home.
