For pumped hydro to be viable it needs cheap, reliable power supply in off peak times (every day of the year).

Pumped hydro is enormously expensive and much more expensive if used for storing energy from intermittent renewable energy supplies as distinct from reliable baseload supplies when power is cheap (midnight to 6 am) for release during the day, regularly almost every day of the year.

An electricity grid powered b y mostly nuclear power (like France) with some pumped hydro and some gas for peaking, abates more CO2 than a mostly renewable energy powered grid, and does so ant about 1/3 the abatement cost.

Contrast this with the area of reservoirs required if pumped hydro energy storage was used: Assuming two reservoirs with vertical separation of 100 m and 10 m active storage depth in each, we'd need with 300 square kilometres of reservoirs to power NYC for 3 days.

Wind with pumped hydro energy storage is about 30 times more costly than nuclear to provide reliable dispatchable power.

Batteries continue to get better all the time, and even simpler solutions such as hydro power from an enclosed system where the wind (when it's blowing) is used to pump water into storage reservoirs at the top of a hill or mountain or storage tank, and then when there's demand for power but no wind, the water is drained down to a bottom storage space and hydro power is generated from the falling water.

New storage projects are in the news all over, including a 10 - MW battery coupled to a Southern California Edison gas turbine; a multi-kilowatt flywheel that will store four hours of power for Hawaiian Electric; and a proposed 393 - MW pumped hydro project in southern Oregon's Klamath basin that faces opposition from local tribes.

Combining pumped hydro and wind power could make Kangaroo Island a very serious source of electricity, including base - load electricity.

In areas where abundant hydro capacity and water to power it are not available, the only way to solve this problem is to build very extensive pumped storage facilities to generate «artificial» hydro power.

The Prosper - Haniel hard coal mine in the German state of North Rhine - Westphalia will be converted into a pumped hydro storage site for excess renewable power when it closes next year, announced Governor Hannelore Kraft in March.

This means more use of batteries, pumped hydro - power, solar - thermal with storage, possibly things like using excess electricity to convert water into hydrogen and oxygen and storing that until it is needed.

In the case of El Hierro, unlike most of the existing pumped storage systems worldwide, the reservoir has been created artificially just for storage purposes, instead of using an existing hydro power plant with a typical dam on a river used to create the reservoir.

If much more wind power is developed, we will have to look at sustainable methods of generating electricity, including pumped hydro - power.

Of course developing pumped hydro has its own cost, but power that can be generated on demand and at short notice receives high prices in a supply and demand based power system, so it could prove to be economically justified.

To make the power system work I'd have pumped hydro storage, compressed air energy storage and battery storage to spread the energy across the demand periods.

A more environmentally friendly way of generating power at peak load is pumped hydro.

Pictured at the right is one of a very few hydro - power stations combined with pumped - hydro energy storage currently in Australia (it is in NSW, not South Australia).

Conventional pumped hydro systems use vertically separated reservoirs to utilize the power of water and gravity; during times of low demand (off peak), water is pumped using excess energy from the lower to the upper reservoir.

If the price of wind power falls far enough and my estimates of new pumped hydro costs are correct, then by the end of the decade, for CF = 32 % wind sites near suitable land to be sacrificed for pumped hydro, such wind + storage solutions will become price competative with nuclear.

Or, we could use that hydro - generated electricity to power a pump and pump that water up into a water tower, turning the electrical energy back into potential energy.
