Targeting businesses and property managers, Flo Energy aims to deliver scalable green energy solutions without outages or hidden fees during transitions (source: floenergy.sg).

Projects & Track Record

Flo Energy has established a strong track record in renewable retailing, focusing on customer onboarding and service delivery rather than large-scale project capacities (source: floenergy.sg). The company serves a diverse clientele, including businesses seeking Eco Office and Eco Manufacturing certifications through RECs, and has implemented rooftop solar monitoring solutions during the COVID-19 pandemic (source: floenergy.sg). Key partnerships, such as with Vitol for global scaling and Holistics for data analytics, have been instrumental in maintaining an 80% monthly active user rate among its team (source: floenergy.sg). With a geographic focus on Singapore and an expanding presence in Australia, Flo Energy is committed to providing comprehensive market coverage as a licensed retailer (source: floenergy.sg).

In 2023, Flo Energy expanded its operations to Australia by opening an office in Melbourne and launching Flo Energy Australia under Flo Holding (source: floenergy.sg). The company secured investment from Vitol to accelerate its market entry and growth in the region (source: floenergy.sg). In 2024, Flo was recognized in the SME100 Awards Hall of Fame for its innovative contributions to solar solutions and energy management (source: prnewswire.com). A November 2024 press release highlighted Flo's status as Singapore's fastest-growing independent retailer, reflecting the company's adaptability to SME cost priorities (source: prnewswire.com).
