David Energy is a New York City-based energy provider that helps businesses lower their electric bills through a combination of free plug-in battery systems and smarter energy supply management. The company charges batteries when grid power is cheapest and discharges them during peak or expensive periods, reducing the demand and infrastructure costs that typically make up a large portion of commercial utility bills. Customers pay nothing for the batteries, installation, or maintenance, and receive transparent monthly reporting comparing what they pay David Energy versus what they would have paid their utility. David Energy operates as a licensed electricity supplier in New York, meaning customers receive two bills: one from David Energy for electricity supply and one from their utility for delivery infrastructure. The company also provides complementary services at no additional cost, including bill monitoring to catch errors and scams, smart thermostat management for multi-location businesses, and dedicated energy advisors who proactively guide clients on further savings opportunities. David Energy's model is positioned within the broader green energy transition, addressing the growing strain on grid infrastructure caused by electrification trends and AI data center demand. By optimizing when and how businesses draw power from the grid, the company contributes to more efficient energy consumption and reduced peak-load pressure, which supports a cleaner and more resilient urban energy system. The company has been featured in news coverage highlighting adoption by NYC retailers and food service businesses, and differentiates itself through a partner-oriented, high-engagement customer service approach.
