Energy Storage is Described as a Dream in Poland, but is Rapidly Expanding in the United States

This is really a bit counter-intuitive, since electricity is much cheaper in the United States. But storing excess electricity for subsequent use to meet peak demand periods or down-time in the grid is moving ahead in the United States where there is lower marginal economy for storage than in Poland.

"...21 U.S. states now have 20 megawatts of energy storage projects proposed, in construction or deployed. In fact, 10 U.S. states have pipelines greater than 100 megawatts."  GTM Research, March 2017.

You have to also note that 20 MW of storage is comparable to a 40 MW peaker plant, since the 20 MW capacity occurs ion the tip and bottom of demand. Ironically, energy storage seems likely to increase the profitable of remaining fossil fuel plants which depend on high levels of utilization to be profitable at all. Keeping fossil fuel, especially coal capacity as in Poland, on hand just to meet the very top of peak demand is very inefficient.

In yet another area, we are seeing Poland get further and further behind, as politicians and the energy company executives they politically appoint seem totally out of step with the economic and technical trends in their sector.
