No matter how much generating capacity is installed, there will be times when wind and solar cannot meet all demand, and large-scale storage will be needed. Historical weather records indicate that it will be necessary to store large amounts of energy (some 1000 times that provided by pumped hydro) for many years.

In electrical islands, frequency excursions are sizeable and automatic load shedding is often required in response to disturbances. Moreover, the displacement of conventional generation with wind and solar plants, which usually do not provide inertial response, further weakens these power systems. Fast-acting storage, by injecting power

Fluctuating solar and wind power require lots of energy storage, and lithium-ion batteries seem like the obvious choice—but they are far too expensive to play a major role.

Physical resource assessment showed that wind and solar power potential is rich in the northwestern provinces (>3000 TWh yr −1) but much smaller in the east and south (<800 TWh yr −1), and the potential of solar energy is higher than that of wind in most provinces (Fig. 1 a). However, the best resources are far from demand centers (Fig.
