Virtual Power Plants (VPPs): How Smart Devices Can Help the Grid

What happened

• A Virtual Power Plant (VPP) is a collection of household devices (like smart thermostats, home batteries, and EV chargers) that a utility company can control.
• Utilities command these devices to use less electricity during peak hours, helping manage demand.
• Participants in VPP programs receive rewards, such as discounts on energy bills or signing bonuses.
• VPPs have a profound impact when scaled up, potentially equivalent to firing up a power plant at the scale of hundreds of thousands or millions of homes.
• As of 2023, there were over 500 VPP programs in the US, and an estimated 4 million households with smart thermostats were enrolled.

Why it matters for me

VPPs allow consumers to potentially save money by adjusting energy usage based on grid demand. While some programs focus on smaller rewards (like $50-$150 bonuses for thermostats), home battery and EV programs can lead to hundreds or thousands of dollars in annual savings. If implemented well, VPPs can help utilities avoid expensive grid upgrades.

What to remember

• Check if your utility company offers a program and ensure your devices are supported. Look for terms like ‘demand response’ or ‘smart thermostat rewards’.
• Understand the flexibility you have; some households may not have enough flexibility due to work schedules or caregiving responsibilities.
• Review the opt-out rules, as participants usually have the right to override temporary changes made by the utility.
• Be aware that data collection occurs; while data is limited and functional, it can reveal patterns about home routines.
