DTE SPARK (Suppliers, Partnerships, Access, Relationships, and Knowledge) Supplier Advancement Team

Joi Harris, President and CEO, DTE Energy

"At DTE, we are committed to building a high-quality, local, cost-effective, and inclusive supply chain that drives innovation and delivers the best value for our customers” – Joi Harris, president and CEO, DTE

Our Mission

We act on this commitment by pursuing partnerships with businesses that provide the strongest combination of service, quality, and price. We seek out the highest-value suppliers — including small and local businesses owned by women, veterans, members of the LGBTQ+ community, and disabled-owned business enterprises.

Through outreach, mentoring, and training, we cultivate meaningful relationships with these companies and encourage them to explore opportunities to partner with us and with our other suppliers. This creates a future-ready, resilient supply chain that gives every supplier a fair chance to grow.

Our focus on doing business in our home state opens the door to potential opportunity so that all qualified businesses have a fair chance to compete for our contracts, strengthening local economies across Michigan.

Our dedication to ensuring competitive access for inclusive, local and small businesses is anchored by our responsibility to provide safe, reliable, and affordable services. Therefore, our procurement decisions are ultimately based on merit. We evaluate all vendors through a competitive process focused on such factors as safety records, technical expertise, operational reliability, and cost-efficiency. 

By broadening our search for talent while maintaining high standards for cost-effectiveness and excellence, we ensure the greatest benefit for our customers and the communities we serve.
