Utilities expand virtual power plant programs paying households for smart devices
Virtual power plants let utilities remotely adjust smart thermostats, EV chargers, batteries and solar panels in homes to reduce strain during peak demand, in exchange for bill discounts or signup bonuses. More than 500 such programs already run across the US, with about 4 million smart-thermostat households enrolled as of last year, and interest is growing as companies like Google invest in the technology to support data centers.
