Electricity Pumped Storage Systems Using Underground Reservoirs: A Feasibility Study for the Antelope Valley Water Storage System
Evaluating the potential of pumped hydro storage with water banks for improved grid operations.
The research team conducted technical feasibility analysis and preliminary field testing of two pumped storage systems: Peak Hour Pumped Storage (PHPS) and Aquifer Pumped Hydro (APH) storage at Willow Spring Water Bank. Hydropower generation and demand response potential of groundwater banking projects were assessed. The results show low efficiency and revealed water quality issues as a potential barrier for implementation for the APH system. The demand response during a dry hydrologic year has the highest value based on analysis. The project also created tools for other groundwater banks in California to conduct similar analysis. The project was completed as planned in September 2017 and the final report is published.
The project conducts a feasibility study that determines the value of energy storage and associated grid support benefits provided by Peak Hour Pumped Storage and Aquifer Pumped Hydro applications at an existing water bank. The feasibility study also identifies critical parameters for success for both technologies and identifies other water banking sites in the state where these technologies are likely to be successful.
This project assessed two promising energy storage technologies that can be used to firm up variable renewable energy generation and other fluctuations on the electric grid.
