I'm confident that battery cost reductions will be substantial when Tesla's Gigafactory is at full production (they've already signed yet another utility scale battery storage deal in the last 10 days), cost reductions that will further increase uptake in energy storage contracts.

Cumulative global installed solar photovoltaic capacity will surpass 310 GW this year, compared with just 40 GW at the end of 2010. Polysilicon module prices continue to plummet; even if storage costs have not caught up, we can continue to drive out fossil fuel generation with more solar and wind, not to mention shifting loads to renewable generation hours whenever possible.
