States are creating renewable portfolio standards (RPSs) that require utilities to run off a certain percentage of renewables. With the new RPSs and current emission standards the dynamic of the grids energy and reliability needs are changing. Because RPSs and emission standards, utilities are procuring the cheapest renewable resources, which tend to be solar and wind. As RPSs increase over time this causes higher procurements of solar and wind. Higher procurement and increasing penetration levels of solar and wind is causing their energy values to decrease as well as some reliability concerns. While geothermal energy value will continue to stay relatively constant and maintain reliability. Looking toward the future, market participants should be looking at how geothermal energy can be utilized to meet RPSs and maintain grid reliability. This poster will be discussing how increasing levels of solar and wind can start causing issues with the functionality of the grid and how geothermal can possibly combat these issues.
