Caracas energy storage power plant operation

How will a large-scale hydro power plant work?

Surplus wind electricity is stored in the upper reservoirs and helps to smooth the wind generation output. The projected large-scale hydro 250 MW PHS, with a total of 8–10 hours’ storage, would combine a total capacity of 320 MW solar PV and 150 MW wind (Iannunzio, 2018).

What is the maximum capacity of a storage plant?

Assuming an average plant size of 40 MW, the maximum total capacity of this type of storage can be expected to be between 5 and 10 GW. Note that Quidnet estimates total resource potential for this technology in the United States at over 500 GW.

Can pumped storage be used in a hydropower plant?

Because of the small footprint and minimal civil works required for the construction of wells to house generating units, this technology may also be applicable for the development of pumped storage capabilities at existing hydropower plants, as well as for applications at non-power dams.

What is a scalable power plant design?

The design is scalable for larger plant sizes (i.e., >300 MW). Capacity can be chosen to match the demand for both electricity and heat. Typical electrical capacity range is 300–1,000 MW, while the thermal capacity depends on the regional/urban demand needs.

How long does it take to build a power plant?

Construction time: Because of the reduced scale of the project, use of prefabricated storage tanks, standardized pump-turbines and generators, and reduced civil works, technology developers estimate a construction time of 12 to 18 months.
