What Walker-Miller Energy Services does

Walker-Miller Energy Services is a Detroit-headquartered, founder-led Certified B Corporation that delivers energy efficiency and clean energy programs on behalf of investor-owned utilities, municipalities, and government agencies. Founded in 2000 by Carla Walker-Miller, the firm generated $68.7M of revenue in 2024 with 107 Michigan-based employees and operates from six offices across Michigan, Illinois, and Pennsylvania. Its services span energy waste reduction program implementation, electric vehicle charging infrastructure deployment, medium- and high-voltage equipment sourcing and procurement, workforce development and BPI-certified training, and inclusive community outreach targeting historically marginalized populations.

The underlying technology stack is operations and program-delivery software rather than a singular platform: a proprietary Equity Assessment Tool for mobility research, a mobile-friendly Energy Saving Kits portal, the Walker-Miller Clean Energy Academy for BPI certification, and a Diverse Contractor Incubator program. The firm also serves as prime distributor for AM Conservation Group's residential, multifamily, and commercial energy- and water-saving products. Certifications include ISO 27001, SOC 2 Type II, BPI Goldstar Contractor, ANSI-accredited BPI training partner status, and DOE Home Energy Score Partner.

Walker-Miller's revenue model is enterprise-managed services and professional services billed primarily through multi-year utility and government contracts. Major customers include ComEd, DTE Energy, Consumers Energy, and CLEAResult (strategic partnership), with additional distribution through community organizations, housing authorities, and AM Conservation Group resellers. The firm is founder-owned, has no disclosed institutional investors or parent company, and positions itself through an equity lens as one of the largest African American and woman-owned energy efficiency firms in the United States, with growing recognition as a thought leader in clean energy equity via the RECESS conference (now an independent 501(c)(3)).
