Peak-valley tariffs and solar prosumers: Why renewable energy

This is because the peak-valley mechanism is still insufficient to identify all potential spikes in power supply, so the storage and reserve capacity resources cannot reach the efficient allocation. As a result, to encourage storage and reserve capacity, peak-valley mechanism that more accurately coordinate supply and demand is needed.
