About the role
DESRI seeks talented, intellectually curious, and highly motivated students to join our Summer 2027 internship program. The internship is a 10-week program that runs from June through August, depending on academic calendars.
The Commercial Internship serves DESRI's Finance & Acquisitions and Strategy teams and offers interns the opportunity to contribute to the investment, financing, strategic analysis, and growth of DESRI's renewable energy platform. Interns will work alongside experienced professionals on high-impact projects involving solar, battery storage, and wind assets across the United States.
Throughout the summer, interns will work closely with mentors and project managers who will support their professional development. Interns will have opportunities to collaborate across DESRI, participate in learning and intern events, visit an operating renewable energy asset, and present their work to colleagues at the end of the summer.
