How to write a feasibility analysis for pumped storage

Can pumped storage schemes improve economic viability?

To sum up, the results suggest that the economic viability of the pumped storage schemes can be further improved when there is a need for higher energy storage capacity, more days of autonomy, when a low discount rate is applicable, and as PV panel prices decrease. 5. Conclusions and suggestions

What is a feasibility study?

A feasibility study is the initial phase of a project that assesses its potential for success. In the context of hydropower development, it involves creating maps at scales of 1:1,000 to 1:5,000 to evaluate maximum output and plant discharge.

What is the scale used for a feasibility study?

A feasibility study is conducted using maps at a scale of 1:1,000 to 1:5,000. Maximum output is the power output which the power plant can generate.

How do you calculate pumped storage efficiency?

The overall efficiency of the pumped storage scheme combined with a mall battery bank is given by: (11) η ps = α · η p · η t + ( 1 - α) · η p · η t · η BI The calculated overall system efficiency is 21%, which is approximately 1/3 that of the battery storage scenario.

Is pumped storage a cost competitive option?

The economic benefit of pumped storage is more significant in the case of storage by pump alone if using a hydraulic controller (Option 4), with the lowest LCC among all options. The sensitivity analysis showed that pumped storage would be even more cost competitive if the parameters of energy storage capacity and days of autonomy were increased.

What is the gross efficiency of a pumped storage power plant?

The gross efficiency of a pumped storage power plant is generally about 70%.
