しろくま電力株式会社 Tech Stack

Renewable energy developer building solar, wind, and EV charging infrastructure across Japan

Utilities 港区, 東京都 201–500 employees Founded 2016 Privately Held

Shirokumapower (formerly afterFIT) develops and operates renewable energy generation assets—solar farms, wind projects, and EV charging networks—across Japan. The company's 2024 rebrand from afterFIT to refocus on structural electricity cost reduction signals a shift from post-FIT subsidy survival toward competitive, unsubsidized renewable deployment. The tech stack spans CAD, Python, PostgreSQL, and AWS—tools suited for site planning, forecasting, and remote monitoring—with active adoption of Google Apps Script suggesting internal automation of operational workflows. Current hiring remains engineering-focused (8 roles) with early-stage product and sales coverage, reflecting a scaling challenge in managing distributed assets across generation, trading, and grid integration.
