The “Hydropower Plants as Black Start Resources” report identifies the advantages of using hydroelectric power for black start and compares hydropower with other types of power plants for providing this valuable service to ensure the resiliency of the power grid.
The report provides an overview of the critical role of black start capability to ensure timely restoration of grid operation after a major power grid outage. It discusses the sequence of operations to black start (power up) a power plant and to restore the grid after a major blackout. In this context, the report discusses how the types, sizes, characteristics, and locations of black start–capable units affect the speed of recovery. In turn, the characteristics of various power generation technologies are compared with the attributes needed to quickly and efficiently power up a black start plant and re-energize the power system for normal operation.
