Pumped storage power plants (PSPP) have to be available on demand, to quickly balance load fluctuations, i.e. inject fast power to the grid in peak load times, or extract power from the grid in times of overcapacity when high amounts of solar or wind power feed the grid. From fast response to small network fluctuations up to securing a stable power to avoid larger blackouts, pumped storage power plants have to dynamically react within a short time.


Fixed speed PSPP cannot provide power variation in pump mode when it comes to absorbing the excess of wind or solar energy produced

Conventional PSPP cannot provide grid frequency control in pump mode

A conventional PSPP needs approx. 5 minute start up time in pump mode.

The GE Advantage

Each large hydro power plant project is unique. Whatever matters most, with our full range of water to wire solutions, we help you to optimize grid performance, reduce system and operating cost, enhance energy output and lower overall project risk by benefiting from our enterprise synergies and proven track record in hydro power. For example, GE`s variable speed drive solutions for Pumped Storage Power Plants (PSPP) enable up to 10% more power production in turbine mode and up to 15% reduction in electricity consumption in pump mode.


Adjustable pumping power
GE`s variable speed drive solutions provide up to 30% power variation in pump mode with voltage source inverters (VSI) doubly fed, and 100% capacity with VSI fully fed for dynamic frequency control.

Faster start up time
The PSPP can start within <10s with GE`s fully fed converter solution.

GE's Offering for Hydro Power Applications

GE Energy Connections offers all power conversion and grid integration equipment for large hydro power plants i.e. pumped storage, run-off-river and tidal applications, from their design and optimization to manufacturing, installation and commissioning, as well as life time services. GE can design and supply the necessary generators, drives, and power conversion systems essential for meeting grid code compliance and the high reliability required by on- and off-shore applications.
