Here's the numbers from the NPCC [Northeast Power Coordinating
see Summer 2008 for a pie chart;
"Relative Capacity by fuel mix"
Pumped storage 3%
Dual fuel 18%
A third Hydro and 1/2 as much Nuclear. Wonder which fuels are
included under 'dual fuel'?
I can help with that one. Blenheim-Gilboa gave us a lot of work
moving telephone lines back in the 70's.
It is in Schoharie county- roughly halfway between NY City and
Essentially 2 lakes. Pump up at night using wasted hydro from
Niagara falls. Let it flow through turbines during the day to
supply power to most of the east half of NY.
Here's their site-
Probably oversimplified, but I've always looked at them as a 'battery'
for the big falls. I don't know how many others might be around.
Pretty good analogy. Actual count I don't know, but over the country
there are quite a number -- Smith Mountain in SW VA and TVA has a couple
w/ some plans for additional a few years ago; don't know what happened
to that since I left TN.
Problem is like rest of hydro, the number of suitable sites is pretty
well used up and there's the environmental impact of flooding other
areas that's a big problem most places these days that didn't use to be
so much an issue.
