SponsorsIndustry members are invited to join one or more Ecosystem Groups and participate in ad hoc projects to develop public comments or help work through policy challenges.
Through Strategic Partner Networks, Ecosystem Groups bring together leaders quarterly to explore open innovation, emerging technologies, and forces disrupting the clean energy landscape. These groups serve as dedicated platforms for forming strategic clean energy relationships. Within these SPNs, members collaborate to identify new market opportunities, develop key partnerships and stay ahead in a rapidly evolving industry.
Market Development
Networks accessible to industry members help established corporations form partnerships with early-stage companies and clean energy ventures to find opportunities to innovate, collaborate and expand their businesses.
Influencing Policy
Convening ecosystem groups regularly helps industry leaders and innovators better understand market needs and collectively advocate for reforms in Massachusetts that make climate tech more competitive.
Fostering Collaboration
Energy players that operate without engaging with peer networks risk undermining one another’s progress when there is ample opportunity to collaborate. Ecosystem groups create the space to spark these important conversations.
