What Tepco HomeTech does
TEPCO HomeTech (TEPCOホームテック株式会社) is a Tokyo-based residential energy management company founded on August 9, 2017 as a joint venture between Tokyo Electric Power Energy Partner (51%) and EPCO (49%), operating under the TEPCO group umbrella with ¥475M paid-in capital and ¥950M total contributed capital. The company plans, designs, and constructs energy-conservation solutions for new and existing residential buildings, holding a general contractor license and specialty permits across plumbing, electrical, interior finishing, and building work.
The company's core offering is "Ene Kari" (エネカリ), a zero-upfront-cost subscription service that bundles multiple energy-efficient equipment types — solar photovoltaic systems, residential lithium-ion storage batteries, EcoCute heat pump water heaters, IH induction cooktops, and V2H (Vehicle-to-Home) bidirectional chargers — into 10- or 15-year contracts with monthly flat-rate fees, free repairs, 24/7/365 call center support, natural disaster compensation, and free equipment transfer upon contract completion. Secondary product lines include portable battery systems (e-block 304Wh and stand-alone 3.5kWh), the UX Connector LITE external power connection panel for disaster preparedness, EV/PHEV home charging equipment, and a parallel "Rental Owner Ene Kari" subscription variant for property owners and real estate management firms. Underlying technology spans heat pump water heating, PV generation, lithium-ion storage, V2H bidirectional charging, and induction cooking, all integrated under a single managed energy stack covering generation, storage, and consumption.
The revenue model blends recurring subscription fees (the primary stream) with one-time equipment direct sales and construction/installation services. Distribution is hybrid: an inside-sales call center (0120-948-356) and web inquiries drive direct-to-consumer acquisition; a dedicated B2B enterprise sales team manages relationships with housing developers including Nomura Real Estate, Sumitomo Real Estate, Odakyu Real Estate, Arnesuto One, and Mitsui Fudosan Residential, which embed Ene Kari into their new housing developments; and an authorized dealer network serves areas outside the TEPCO Power Grid territory. Geographic reach is nationwide in Japan, with the company headquartered in Sumida-ku, Tokyo.
