- Summer Energy Holdings, Inc. Summer Energy Holdings, Inc. (SUME) operates as a retail electricity provider, procuring wholesale power and reselling it to commercial and residential customers through competitive fixed-rate plans, including 100% renewable options; it offers customizable billing, customer service, collections, and remittance services in restructured energy markets. The company serves designated target markets across multiple states, including Texas, Ohio, Illinois, Pennsylvania, Massachusetts, and New Hampshire, with primary focus now on business customers following the divestiture of residential services. Founded in 2005 and headquartered in Houston, Texas, it conducts operations via wholly owned subsidiaries such as Summer Energy, LLC, Summer Energy Midwest, LLC, and Summer Energy Northeast, LLC. In recent developments, Summer Energy, LLC sold its non-prepaid residential customer book in Texas to US Retailers LLC in February 2024 for approximately $8.1 million and divested the majority of its non-prepaid commercial customers in Texas to Atlantic Energy Group LLC in July 2025 for about $6.5 million, streamlining its portfolio to emphasize commercial offerings. These transactions reflect a strategic shift toward optimized operations and business-focused energy solutions amid competitive retail markets.
