Surprise Valley Electrification Corporation (Surprise) would demonstrate the potential geothermal resource near Paisley, Oregon. In Phase I (exploration and geothermal modeling), the existing geothermal irrigation wells were found unsafe and nonconducive for the project. Therefore, Tasks 1.3 and 1.4 were modified, so another National Environmental Policy Act review was needed. Once the modeling is complete, the data would be used to locate drilling, flow testing, power plant site selection, power plant installation, transmission upgrades, connecting to the grid. A land use and development agreement was reached between the surface owner (owning the water/mineral/geothermal rights) and Surprise on June 24, 2009. The project would be divided into three phases with multiple tasks.
