It is no secret that renewable energy project development cycles present many unique challenges — as well as promising opportunities — for developers, investors and power users alike. Geothermal energy project development in particular can be a challenging endeavor, based on the extended timelines involved in successfully proving a resource, mitigating drilling risk and managing the subsurface reservoir on an ongoing basis. These are unique “geo sector-specific” issues that must be managed, in addition to the typical power plant development and construction issues inherent in any energy project endeavor. Due to these challenges, the corresponding financing of geothermal projects must be carefully tailored to match these specific features.
