What They Do
SB Energy is a U.S.-based renewable energy developer that serves as the primary platform for SoftBank Group Corp. to deploy solar power, energy storage, and related climate infrastructure across North America (source: sbenergy.com). The company focuses on utility-scale solar photovoltaic (PV) projects, battery energy storage systems (BESS), and grid-integrated solutions, which are essential for delivering flexible renewable energy generation (source: sbenergy.com). SB Energy's offerings include greenfield development, project acquisition, and the operation of solar farms and storage facilities, with a notable framework agreement with ESS Inc. to deploy 2 gigawatt-hours (GWh) of long-duration iron flow batteries by 2026 (source: sbenergy.com). The company targets the U.S. utility sector, data centers, and high-demand clean energy customers, having raised over $10 billion in total project financing since its inception, including more than $4 billion in tax equity and debt (source: sbenergy.com). SB Energy's competitive edge lies in its rapid execution, having brought nearly 2 gigawatts (GW) of solar online within two years of its founding, leveraging SoftBank's AI and technology ecosystem alongside Ares' infrastructure expertise (source: sbenergy.com).
Projects & Track Record
SB Energy has achieved operational status for nearly 2 GW of solar capacity within just two years of its founding in 2019, although specific project names and individual capacities are not detailed in available records (source: sbenergy.com). The company is currently engaged in major projects, including the deployment of 2 GWh of ESS long-duration storage across multiple sites through 2026, with the first delivery slated for California (source: sbenergy.com). SB Energy's client base includes partnerships with ESS Inc. for storage technology and leading financial institutions that have provided over $4 billion in financing for its projects (source: sbenergy.com). The company also has a significant presence in Japan, where its operations powered approximately 128,180 households through 34 solar plants, totaling over 408.5 MW as of October 2017 (source: solarplaza.com). SB Energy's U.S. operations are primarily based in California, with plans for further expansion across North America, distinguishing itself from SoftBank's divested international arms (source: climatebase.org).
Recent Developments
In the past two years, SB Energy secured a landmark strategic equity investment of up to $600 million led by Ares Management, aimed at accelerating its U.S. renewables platform and scaling digital infrastructure (source: sbenergy.com). The company also finalized its agreement with ESS Inc. for the deployment of 2 GWh of long-duration storage by 2026, marking a significant milestone in hybrid energy solutions (source: sbenergy.com). While no major acquisitions or new funding rounds beyond the Ares deal have been reported for the U.S. entity, SoftBank's broader divestitures included selling control of its Japanese SB Energy to Toyota Tsusho in February 2023 (source: wikipedia.org). Additionally, the company pursued a sale of its 80% stake in the India unit, which has a 7.7 GW portfolio, although this deal was later called off (source: pe-insights.com). SB Energy has also received recognition as a Great Place to Work, highlighting its positive workplace culture (source: greatplacetowork.com).
Working There
SB Energy offers a variety of roles across several departments, including development and origination, grid integration, operational excellence, finance, capital markets, and legal/compliance (source: sbenergy.com). The company is primarily hiring for positions at its San Francisco Bay Area headquarters and project sites, particularly for its California storage deployments, aligning with its U.S.-centric growth strategy (source: sbenergy.com). SB Energy's culture emphasizes an ownership mindset, team learning, and growth, welcoming diverse perspectives and ideas while pursuing its mission with enthusiasm (source: sbenergy.com). The company has been certified as a Great Place to Work since its founding in 2019, indicating a commitment to positive employee experiences (source: greatplacetowork.com). Specific benefits packages have not been publicly documented in available sources.
