A summary of the report is presented in Fig. 8.2. Figure 8.2. Levelized cost of storage comparison.
Pumped hydro storage systems face a lot of challenges in their utilization though they have seen many successes. The amount of time taken for the PHES to be commissioned as functional is not an easy task at all. PHES project developers face a regulatory timeline for the development of new projects.
Current pumped storage round-trip or cycle energy efficiencies exceed 80%, comparing favorably to other energy storage technologies and thermal technologies3. This effectively shifts, stores, and reuses energy generated until there is the corresponding demand for system reserves and variable energy integration.
In addition to the design basis considerations for instrumentation that is discussed in section 1 of this document, the following additional considerations should be considered regarding the design, testing, operation and maintenance of level instrumentation in a pumped storage plant. Field instrumentation is essential for operational safety.
Accordingly, when the operational basis of a pumped storage facility has changed or a change is being contemplated, the original design basis of the facility should be reviewed and the following items considered in order to assure the owner the safety of the facility has not been compromised to an unsafe level.
On January 13, 2006 the Federal Energy Regulatory Commission (FERC) issued a letter to all licensed pumped storage projects requiring them to be staffed and monitored twenty-four hours per day, seven days per week.
