Aligned Ambitions and Values

Constellation’s suppliers are committed to the environment, safety, and transparency. The right business partners help create results that are off the charts. 

Constellation believes in seamless, transparent supply chain solutions. We welcome new suppliers that can help us meet our daily demands, future requirements, and support our emergency response efforts with innovative solutions. 

Constellation believes in a green, sustainable supply chain.

We were the first U.S.-based energy company to join the Carbon Disclosure Project’s Supply Chain Leadership Collaboration, our work includes the development of voluntary, consensus-based standards for evaluating the environmental attributes of key materials and services provided to the industry .

The Constellation culture demands safety-first suppliers.

Constellation is committed to assuring safety at all times, and our policies foster a culture of safety. To protect the safety and health of our employees, contractors, customers and communities, we’ve implemented a number of initiatives to promote safe behaviors both on and off the job. Among them: we conduct rigorous safety training for employees, starting with their first day of orientation.

Constellation expects our suppliers to have the same commitment to these standards.

Suppliers can also contribute to our culture of innovation.

The energy industry is being transformed by new energy sources coming onto the grid from consumers who produce their own energy with rooftop solar panels and fuel cells. Add to that the potential of Web-based analysis and functions, the “Internet of Things,” mobile, cloud, social, even drones, and anything is possible.

Constellation fosters a culture of innovation inside the company with initiatives like TechEXchange and Innovation Expos, and by encouraging and recognizing individual innovation efforts. We also look to form mutually beneficial partnerships outside Constellation with, for example, Constellation Technology Ventures.
