GE Renewable Energy has secured a contract from PGE Odnawialna in Poland to replace four 125 MW pumped turbines and generators at Porabka Zar pumped hydro storage plant. GE Hydro Solutions will design, manufacture and supply equipment and provide the excitation and governing systems, as well as replace the 40-year-old turbines with new high-efficiency pumped turbines and motor generators. It will also replace the existing stay rings and stay vanes with new ones specially designed for Porabka Zar.

Renewables growth to bolster need for pumped hydropower storage, developments mainly in Asia

Renewables growth to bolster need for pumped hydropower storage, developments mainly in Asia

December 1, 2022 |

Pumped hydropower storage utilises pumps to drive water to a reservoir at a higher altitude for large-scale long-duration energy storage, and turbines to generate electricity when the stored water is released. Typically, when on-grid electricity demand and prices are low, operators draw electricity from the grid to power pumping systems. Conversely, when demand is high, operators release water to generate electricity either to sell back to the grid or to power their own needs.

Robust Pumped Storage Growth To Reinforce Mainland China’s Renewables Growth

Robust Pumped Storage Growth To Reinforce Mainland China’s Renewables Growth

May 29, 2022 |

We have recently revised up our hydro-electric pumped storage generation and capacity forecasts for Mainland China, following positive developments in the sector. Mainland China is the top-performing market in Asia for pumped storage, with a total of 36.4GW of capacity as of end-2021. Over the coming years, we expect Mainland China’s hydro-electric pumped storage capacity to expand rapidly. In September 2021, the National Energy Administration (NEA) announced that it aims for hydro-electric pumped storage capacity to reach 62.0GW in 2025 and 120.0GW in 2030.

Pumped storage hydropower (PSH) operates by storing electricity in the form of gravitational potential energy through pumping water from a lower to an upper reservoir. First built since the end of the 19th  century,  PSH is a mature and proven technology for long-duration energy storage. It has continuously evolved to suit the needs of changing power systems,  providing a suite of power systems flexibility services such as inertia,  frequency control,  voltage regulation, and black-start capability, which are vital to support the growing shares of variable renewable energy in grid systems.

US Hydropower Market Report, January 2021

February 17, 2021 | ,

Hydropower in the United States is used extensively for power system flexibility and resilience. In many parts of the country, hydropower provides more frequency regulation and reserves than its share of installed capacity. In nearly every balancing area assessed, hydropower was more extensively utilized for hourly ramping flexibility than any other resource.
