Focus of the month: Utility scale, grid-connected PV-plus-Storage (12)

In the USA, PV-plus-storage development is being pushed at the federal, state, and local levels (13)

Subsidies for PV plus storage are available at the federal and state levels (13)

In certain states, coupling PV and storage is becoming an obligation (16)

Some utilities have already understood the value of coupling PV and storage (17)

PV plus storage deployment outside the US (22)

Some regulatory bodies require developers to couple storage to their PV farms (22)

Merchant based PV plus storage projects outside the US (25)

Business opportunities: Factors influencing the cost of solar plus storage (26)

The landscape of PV-plus-storage projects has considerably evolved over the last few years (26)

Cost of PV plus storage can vary extensively from one location to another (28)
