Diamond Generating Corporation

CEO Satoru Tamiya leads the firm. SVP of Business Development and Origination Sohinaz Sotoudeh and EVP of Strategy Yuichiro Sakaguchi shape the project pipeline. The firm operates as a corporate subsidiary, so major capital commitments requiring parent-level approval flow through Mitsubishi Corporation's governance.

DGC is a wholly owned operating subsidiary of Mitsubishi Corporation. It does not raise external capital or operate as a fund manager. The firm develops, owns, operates and manages energy projects on its own balance sheet and for Mitsubishi Corporation, acting as both developer and asset manager.

DGC sources projects through its in-house development team, via acquisitions, and through subsidiary platforms. Its distributed generation subsidiary Nexamp originates and develops community and commercial solar projects. The firm also participates in the full lifecycle from greenfield development through to operations, rather than relying solely on third-party acquisition.

DGC is a wholly owned subsidiary of Mitsubishi Corporation, the Japanese global integrated business enterprise. The parent company operates across ten business groups including Natural Gas, Power Solutions, and Mineral Resources, with over 1,700 group companies and approximately 86,000 employees. DGC benefits from Mitsubishi's energy supply chains, customer relationships, and balance sheet support.

DGC operates across North America. It maintains offices in Los Angeles, Boston, and Mexico City, and holds energy assets and provides energy services in the United States, Canada, and Mexico.

Yes. DGC's energy trading and management activities are conducted through Boston Energy Trading and Marketing (BETM), a subsidiary that trades energy commodities and provides asset optimization services across North American markets. This gives DGC an owner-operator-trader structure uncommon among pure-play independent power producers.

DGC's electric generation holdings include wind farms, utility-scale and commercial-industrial solar arrays, battery energy storage facilities, and natural gas-powered combined-cycle and simple-cycle generation. The firm has stated a commitment to reducing its carbon footprint and diversifying its portfolio in clean energy, though it maintains significant gas-fired assets.
