Global financial partners back Onyx

Onyx is backed by global financial partners

Onyx was established in 2014 by Blackstone Group, one of the largest global private equity managers investing in the energy sector. The Company immediately became a nationwide platform for distributed solar generation for commercial and industrial customers. Today, Onyx is owned by SDCL Energy Efficiency Income Trust (SEEIT), a global investor in sustainable energy solutions. This ownership structure provides Onyx flexibility and stable access to long-term capital from major institutional investors, enabling us to deliver highly customized clean energy solutions to our clients.
