What is the pumped storage hydropower guidance note?

This guidance note delivers recommendations to reduce risks and enhance certainty in project development and delivery. It also equips key decision-makers with the tools to guide the development of pumped storage hydropower projects and unlock crucial finance mechanisms.

What should be included in a pumped storage project?

2. C. Each Pumped Storage project should have a design change/ configuration control program. This program should ensure the design basis of the plant is controlled and maintained through procedures and processes that assure unauthorized changes are not made to equipment important to safety.

When should a pumped storage project be staffed?

The January 13, 2006 FERC letter or more current FERC guidance should be considered by the licensee when determining the staffing of a pumped storage project. Un-staffed operation should only be considered when robust fail safe systems, procedures and processes are in place to support unattended operation.

What is the hydrologic design basis for a pumped storage facility?

The hydrologic design basis for a pumped storage facility, as for a conventional hydro project, is mainly concerned with determining the appropriate Inflow Design Flood (IDF) and Probable Maximum Flood (PMF) for the project. Guidance on selecting the IDF and PMF can be found in Chapters 2 and 8 of the FERC’s Engineering Guidelines. 1. A. 1.

What considerations should be considered in a pumped storage plant?

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.

What are the different types of pumped storage projects?

r from a lower to an upper reservoir (Figure 1). There are two principal categories of pumped storage projects:Pure or closed-loop: these projects produce power only from water that has been previously pumped to an upper reservoir and here is no significant natural inflow of water.Combined, mixed or open-loop: combined projects harness both p
