Business overview

GREMZ, Inc. is focused on eliminating information asymmetry in the energy sector. It provides consulting-based sales that reduce energy costs for businesses and households, along with energy-related products and services. Its operations comprise 2 segments: Energy Solutions and Retail Electricity. The Energy Solutions segment sells and provides consulting on commercial solar power generation systems, storage batteries and various energy-saving facilities. It also operates grid-scale battery storage facilities, develops renewable energy projects and retails electricity. Grid-scale battery storage operations generate most of their revenue by supplying balancing capacity to the balancing market, while renewable energy power plants also generate revenue from electricity sales. The Retail Electricity segment supplies power to low-voltage residential and corporate customers through a combination of bilateral electricity trading, including via JEPIX, and market-price-linked contracts. The 2 reporting segments are Energy Solutions and Retail Electricity. The company consolidated and standardized the structure of the former 3 segments, Energy Cost Solutions, Smart House Project and Retail Electricity, used through the previous consolidated fiscal year. The company operates under a holding-company structure and consists of 4 consolidated subsidiaries.
