Terms in plain English
Joules is a 90-day accelerator for advanced grid startups, and its site states that all services are offered to startups at no charge. It does not advertise a cash investment, and it does not publish any equity terms. The offer is advising on financial and business models plus connections to utilities and large energy customers for pilots and revenue opportunities, backed by a 500+ advisor network. Applying means completing a one-page application, emailing it in, and taking an intro call with the team.
Who this is actually for
Pilot-ready gridtech and utility cleantech startups that want a route into utility partners such as Duke Energy and the Charlotte energy ecosystem. Best fit if you have a product ready to deploy or demonstrate with large energy customers rather than an idea-stage concept.
