Our partners at SDG&E have been providing energy at affordable prices which have greatly benefited our residents and their customers. Among rising prices, SDG&E has been consistently looking to lower the cost of your energy bills, leaving you with more money in your wallet. Throughout California, businesses are already paying electricity costs based on when it’s used. Residential households will start making the switch to Time-of-Use pricing plans in March. These plans give you more choice and control for managing your energy use. With these plans, prices are lower all day except between 4 p.m. and 9 p.m. How it works With Time-of-Use, when you use energy is as important as how much you use.
