5 FAQs about [Backfilling plan for the foundation of the seaside energy storage power station]

Do you have the Right Foundation for your energy storage project?

When it comes to energy storage projects, having the right foundation involves careful planning upfront. But each site is different, requiring careful consideration for details like the types of equipment being supported, site location and geologic factors.

What is pumped storage power station (PSPS)?

The pumped storage power station (PSPS) is a special power source that has flexible operation modes and multiple functions. With the rapid economic development in China, the energy demand and the peak-valley load difference of the power grid are continuing to increase.

What is a PSPS hydropower station?

1. Introduction The PSPS is a special hydropower station, which can use the electricity to pump water up to the upper reservoir when the energy demand is low, and release the water back down to the lower reservoir to generate electricity when the energy demand is high.

Why do we need a PSPS reservoir?

The PSPS reservoir construction needs flooding some land, resulting in the land expropriation and resettlement. In order to maintain the social stability and safeguard the legitimate rights and interests of the immigrants, the national policy gives priority to them.

How do pier foundations work?

Pier foundations are typically designed as end bearing, side friction or a combination of both. The cost of pier installation can vary from site to site depending on size, length and site soil conditions. A thorough geotechnical investigation can determine whether the site soil conditions could require special installation considerations.
