Its a bit more than just arbitrage.
There are a number of uses.
1) Due to the switch to wind and solar we sometimes generate too much energy during the day. Batteries can be used to store this and release it when required (evening).
2) When there is a sudden issue with the grid (like the Friday evening a few weeks ago when a gas power plant and wind plant went offline and took down a lot of the South East electricity) batteries can be used to stabilise the grid nearly instantly when an issue occurs allowing time for other power plants to come online.
3) Batteries can be used to smooth the grid at the edges (away from the power stations) where power use changes cause the most "stress" to the grid frequency.
4) Arbitrage - buy the power low (daytime and early hours), sell it high (in the evenings)
Tesla, as well as making home scale batteries, now also make a self contained containerised battery pack allowing industrial scale storage to be constructed quickly and easily by combining a number of these containers. BUT there are competing technologies. Already in the Orkneys they use excess wind energy to produce Hydrogen which is stored and used when required. Also gas liquification using excess energy can happen and then this liquified gas is allowed to warm and the expansion drives turbines to generate electricity -- this has the side benefit of allowing the CO2 to be removed when liquid and separately stored.......
Batteries will be huge for EV's with the real growth in the West happening from mid 2020 - grid scale batteries are already a big hit and offer an investment opportunity (see the GORE and GRID investment trusts as examples)
HZM is a great opportunity - GLALTH
