Time-of-Use Rates Will Turn the Tables for Energy Storage

Published at Renewable Energy World --- It is not always good to be first. Last June, San Diego Gas & Electric (SDG&E) was the first utility in California to hit its net-metering cap and move to Net Energy Metering 2.0 (NEM 2.0). Now, SDG&E will again be the first utility to start the shift to time-of-use (TOU) period, effective on Dec. 1, 2017.
Under California Public Utilities Commission (CPUC) approval on August 24, SDG&E will shift its summer peak time to 4 p.m. to 9 p.m. from the current 11 a.m. to 6 p.m.
The new TOU periods are supposed to help align rates more closely with the cost of service as well as help mitigate the infamous Duck Curve. According to the CPUC, the implementation of TOU rates should provide customers with the incentives to shift some of their peak usage to off-peak times of day when it will be cheaper to do so. This should result in a more efficient grid and lower bills in the long run.
Will solar customers be able to lower bills too?
Moving from “Buy Low, Sell High” to “Buy High, Sell Low”
As part of the transition to NEM 2.0, solar customers are moved from a tiered-rate structure to a TOU rate structure. At that time, some regarded TOU rates as opportunities since customers get compensated higher credits during solar peak production....Read More here
