David Energy

David Energy is an electricity supply company serving businesses in New York City. Its core offering, the "Beat the Utility Plan," pairs retail electricity supply with plug-in batteries that David Energy installs, owns, maintains and manages remotely over a WiFi connection at no cost to the customer. The batteries charge when power is inexpensive and discharge when it is expensive, reducing peak demand and the delivery-related portion of a customer's bill; the company states that roughly half of a commercial bill is driven by when electricity is used and by transmission and distribution charges rather than by consumption itself.

Customers sign a contract with no early termination fee and no capital expenditure, receive an on-site assessment and a custom battery configuration, and then switch their electricity supply to David Energy. They receive two bills — one from David Energy for supply and one from the utility for delivery — and monthly reporting comparing what they paid to what the utility would have charged. Additional services bundled at no extra cost include bill monitoring for billing errors and supplier scams, smart thermostat management with multi-location visibility, and dedicated advisors. The company has also published a Community Solar Plan allowing subscribers to buy power from local solar farms with no installation, and a Bill Health Check report product.

The hardware deployed uses lithium iron phosphate (LFP) chemistry, contains no rare earth metals, and carries Underwriters Laboratories UL 9540 and UL 1741 certifications. Each unit is described as roughly the size of a large toaster oven and weighing about 50 pounds, and installations are performed by licensed, bonded and insured electricians. At contract end, batteries are removed free of charge.

Business model

David Energy sells retail electricity supply to commercial customers while deploying company-owned plug-in batteries at customer sites at no upfront or ongoing cost to the customer, then monetizes the resulting load flexibility.

The company states it earns a small supplier margin on electricity supply, plus revenue from optimizing customer energy use via its batteries and software, including reducing peak demand and participating in grid programs.

Traction

The company cites named business customers and executive testimonials, and press coverage describing NYC retailers including Beard Papa's and Emack & Bolio's, and a Brooklyn bagel shop, using its plug-in batteries to reduce power costs.
