[quote]QUOTE: <i>Originally posted by kevarc</i> <br /><br />Chris, at night we do pump water "uphill" back into the lakes at night, again cheaper power. They do this a lot in the west. <br /> <br />Dunkirk - this is the way it is - Power is a lot more expensive during the day, why would you use the expensive power to pump watrer to use at night. That is just plain dumb. You put it into the grid. Then you use cheap off-peak power to pump water uphill. That is they way it is done. Look at the price chart in the link I put in my earlier post. Solar power is not cheap, it is one the the most expensive of the renewable power sources and higher than any of teh normal power sources. <br />[/quote]kevarc, I am a veteran of two such projects (Wallace Dam and Rocky Mountian) from my time with Georgia Power. The use of reverse pump technology has been around for a while. The use of them as has been spoken of earlier in this thread is to use electricity made at night to do the job. The main reason that the utilities do pump storage is to maintain their heat rates in their coal and nuclear units through the night. In the long run this is a great imporvement in costs of maintaining the generating grid. The longer those units remain consistant in temprature the better and less expensive they become to operate. Standard economics of the matter , the lower the cost, the greater the margin together with a stable rate per kilowatt the higher the profit to the stockholders, the greater the dependability to customers and users at a stable price.
