Core offering

IBeeT provides solar PV and battery energy storage solutions across three segments: residential solar-plus-storage subscription/leasing services (Smart Star 3 with gridshare AI), industrial/commercial on-site solar and storage with self-investment, 15-year lease, or PPA options, and grid-scale battery storage system sales, leasing, and direct facility operations. The company operates its own grid-scale battery storage plants and earns revenue from capacity, supply-demand adjustment, and wholesale power markets.

Product overview

IBeeT operates as a distributed energy solutions provider offering a portfolio of residential and industrial/commercial battery storage and solar products and services. The core portfolio consists of: (1) the Bee Flat residential solar-plus-storage subscription service featuring the Smart Star 3 battery with gridshare AI software; (2) the Bluestorage EnerS50 industrial battery system paired with a local EMS monitoring module; and (3) three interconnected grid-scale battery services — sales/lease of grid storage systems and direct operation of grid-scale storage facilities (1MWh+ container-type). Services are delivered through self-investment, leasing, and PPA models, backed by parent companies ITOCHU and Tokyo Century Corporation.
