Deploying Geothermal Networks at City and Country Scale: A Utility Perspective on Scaling
Nikki Bruno speaks to MIT's IAP course on Geothermal Energy Networks, offered jointly with HEET, about what it takes to scale ground source heat pump networks from single pilot projects to city and national infrastructure. She draws on the Framingham geothermal pilot, the first utility-run neighborhood scale geothermal network in the United States, to walk through the practical obstacles utilities face: permitting, workforce training, financing models, and convincing regulators and ratepayers that networked geothermal can substitute for gas distribution. The talk stays grounded in utility operations rather than policy abstraction, covering how a local gas utility retools itself to install and manage thermal loops instead of pipelines. It closes by weighing what replicating Framingham's approach across a city or country would actually require in capital, labor, and regulatory change.
