Charrette: a meeting in which diverse stakeholders in a project attempt to resolve conflicts and map solutions.

‍

Since 2021, HEET has been bringing diverse stakeholders together in ‘charrettes’ to consider the different aspects of networked geothermal, surface potential problems, and solve them together. Initially a response to the challenge of leading change virtually during the pandemic, this format has evolved to be of great use whether online or in person.

As of fall 2023, we’ve held 12 charrettes attended by over 250 people from across the country, including utility executives, regulators, labor representatives, community advocates, environmental activists, legislators, geothermal designers and installers, and heat pump installers and manufacturers. These working sessions are helping HEET advance the transition from gas to geo at the speed and scale needed to address the climate crisis, while also ensuring equity and affordability.

To suggest a topic for a future charrette or to join our charrette mailing list, please contact us at info@heet.org.

After each charrette, we create a report to share with Eversource Gas, state regulators, charrette participants and others. Take a look here, or find them in the HEET Library.
