Becaon Power is not a company that produces power. Several commenters at one site seem to be unclear on that concept:
Beacon Power bankrupt; had U.S. backing like SolyndraScroll down to to the comments:

Wow! Flywheel energy storage technology? I thought these ‘Perpetual Motion Machine’ devices were ancient history scams.
These individuals are really, really confused.
Beacon Power does not produce kilowatts. I'm sure they never claimed they would. The flywheels, which are not perpetual motion devices, regulate the power that has been produced elsewhere, and the way that power is produced is immaterial.
In the United States, current flows into your house at a particular frequency. Look at anything you have that plugs into the wall. Somewhere on the back, it will say that the device runs on 60 Hz AC, or 50 to 60 Hz AC. In other countries, the energy comes in at 50 Hz. Some devices are less demanding regarding frequency than others, but I don't want to get into that conversation right now.
What Beacon Power is trying to do is to make the frequency of the energy delivered to your house or business exceedingly precise. In other words, the frequency without the flywheels might be 60 Hz plus or minus 0.5 Hz. I don't know; I'm just picking that number out of a hat. With the flywheels, Beacon Power wants to make the precision more like 60 Hz plus or minus 0.05 Hz or plus or minus 0.01 Hz. Again, I'm picking numbers out of a hat. The point is, Beacon Power's product was precision.
The variation now comes from instanteous changes in the load on power plant turbines. The turbines speed up or slow down as the load drops or increases. The power plant can be a gas turbine plant, a coal-fired plant with steam turbines, an oil-burning plant with steam turbines, a nuclear facility with steam turbines, or maybe a hydro facility, though I'm sure not sure about that last one. Solar facilities probably already have some sophisticated frequency regulation, and there's no need to worry about variations in turbine speed. I suppose that wind facilities also have some nice frequency regulation.
When there is a need to correct for frequency variations coming from the power plant, that's where Beacon Power comes in. Beacon Power's flywheels compensate for the change in power plant load, regardless of how that power is produced. I'll bet that Beacon Power is probably more than willing to work with any power producer out there.
Neither is the technology some sort of perpetual motion fantasy, nor is Beacon Power a power producer. Energy stored in flywheels the size of small automobiles rotating at 16,000 rpm is released to the grid when needed. When the instanteous powerline frequency goes up, the flywheels absorb the excess. The trick is how to keep those automobile-size flywheels turning at 16,000 rpm without flying apart, with disastrous results.
Because I don't work in the power generation industry, I might have some details of that explanation wrong, and I invite corrections.
