As energy prices rise and become less reliable, any business that depends heavily on energy will invest in security of supply, kinda like a large scale UPS system. In the UK about 2/3 of the cost of our energy comes from grid maintenance rather than the generation cost. We have started to see intensive energy users install CHP or wind turbines on their sites to help meet their energy needs, this is a very good way of reducing loads on the grid and also reducing operating costs, as the energy should cost less and reliability isnt so much of an issue as the grid is hopefully there if things go wrong.

Energy storage is the easiest way to reduce fossil fuel dependency, electric transport and grid scale storage are desperatly needed :)
