Economic comparison between pumped storage plants and battery storage plants

Making an economic comparison between pumped storage plants and battery storage plants is a complex task that depends on various factors such as regulation, location, energy market conditions, and the specific requirements of the project. 

However, here are some general considerations:

  1. Capital Costs: The capital costs of pumped storage plants tend to be higher than those of battery storage plants. According to some estimates, the capital cost of a pumped storage plant can range from $1,500 to $3,500 per kilowatt-hour (kWh) of storage capacity, while the capital cost of a lithium-ion battery storage plant can range from $400 to $1,200 per kWh of storage capacity. However, it's important to note that the cost can vary widely depending on the specific requirements of the project.
  2. Operating Costs: Pumped storage plants have relatively low operating costs because they do not require a fuel source, while battery storage plants require ongoing maintenance and replacement of the batteries over their lifetime. However, battery storage plants have a higher efficiency and do not require as much water as pumped storage plants, which can reduce their operating costs.
  3. Lifetime: Pumped storage plants generally have a longer lifetime than battery storage plants. A pumped storage plant can last up to 50 years or more, while the lifetime of a battery storage plant is typically around 10-20 years.
  4. Response Time: Battery storage plants have a much faster response time than pumped storage plants, which makes them better suited for applications where rapid response times are required, such as grid stabilization or frequency regulation.
  5. Environmental Impact: Pumped storage plants require large reservoirs and can have environmental impacts such as habitat destruction and alteration of water flow, while battery storage disposal of batteries is a problem we’re yet to face, but as large-scale battery storage proliferates, increasing numbers of batteries will enter the global waste stream. Without careful management of disposal, what cannot be recycled may end up in a landfill and may be corrosive, flammable, or could leach toxins into soil and water.

There are other factors that can be considered too (i.e safety of both the pumped-hydro and battery energy storage systems)
