Renewable Energy Demand Grows; Hydro Power Faces Challenges, Opportunities

In the Northwest, a substantial percentage of our power comes from hydroelectric projects. California’s new legislation requires utilities to provide electricity from 50% renewables by 2030, and Oregon’s new legislation requires the same by 2040. The hydro power industry is viewing these renewable standards as creating continuing demand for hydro power, but several trends are creating serious hurdles for the hydro power industry.

More large projects are going through FERC re-licensing than those large projects that would seek first-time licenses. The result is that older projects are becoming subject to new instream flow and fish passage requirements. The older projects going through re-licensing are usually required to make facility upgrades, and regulate the projects to send more water downstream.

Additionally, climate change means that water patterns are also changing. Scientists predict that more precipitation will fall during the winter, with less flows from snow pack runoff and precipitation in the spring and summer. Predicted changes will create a large burden on facilities that provide flood control, possibly exceeding the amounts of water the facilities were designed to withstand. Further, flows released to meet instream flow requirements in the spring could mean that water is not available for power production and water users later in the season when there is a larger demand.

Moreover, new in-stream storage projects often meet substantial opposition from environmental groups.  Therefore, some innovative hydroelectric developers are constructing out-of-stream projects. For example, the Snohomish Public Utility District in Washington is reviewing an opportunity to construct the Sunset Fish Passage and Energy Project, http://www.snopud.com/?p=1956. An underwater intake structure would divert water from the South Fork Skykomish River, and would flow one-half mile through an underground tunnel to the PUD powerhouse, thereafter emptying back into the river. The PUD would also update the Washington State Department of Fish & Wildlife’s trap-and-haul facility as part of the project. In this way, the PUD proposes an innovative way to create hydro power while satisfying those who are typically opposed to new projects.

Schroeder Law Offices is assisting a client to develop a closed-loop hydro power project using existing agricultural groundwater use rights. It is the first of its kind in Oregon, and will not have undesired effects on surface water streams or fish passage. These types of innovative hydro power designs will need to be used more and more if hydro power is to keep a foothold in renewable energy portfolios in the West.
