Technical FAQs 4

What is “firm power generation”?

The term “firm power generation” is synonymous with “effectively dispatchable solar power.” Indeed, solar power is variable by nature but can be firmed up through various technologies, such as storage, generation blending, or demand response, which can modify the generation and/or load profiles such that they eventually coincide with each other.

What is a 'firm' energy system?

A renewable energy system that consistently meets the electricity demand on a 24/365 basis is said to be firm . From a power system perspective, once the power from renewables is firmed up, it becomes effectively dispatchable.

Can solar energy storage be combined with PV o&pc?

Conclusion By optimally combining energy storage with the PV O&PC strategy, it is possible to close the difference between solar power generation and load demand curves at the lowest cost—this is the essence of firm power generation.

What is pumped hydro storage (PHS)?

Whereas hydrogen can act as a long-duration storage solution, another important alternative is pumped hydro storage (PHS). As compared to hydrogen, which cannot serve as a short-duration solution for the rapid switching between hydrogen and electricity is inefficient, PHS is different, in that, it can be dispatched on an hourly time scale.
