2020 battery storage annual update
Since July 2018, battery storage customers have saved more than $53,858 on their electricity bills.
SMUD customers have installed over 273 battery systems since July 2018 with more than 154 systems currently in the interconnection process. This accounts for over 3 MWh of batteries enrolled in SMUD's Commitment to Operate program, saving battery storage customers approximately $200 each on their electricity bills. The batteries work alongside SMUD's residential Time-of-Day rates to absorb excess solar generation and utilize off-peak energy to reduce the on-peak energy burden on the electrical system.
This shift in energy does more than save customers money. By shifting energy from mid-day solar generation and off-peak time periods to the on-peak time period, customers are also making considerable contributions to reducing GHG emissions.
The estimated annual savings for Residential Commitment to Operate (CTO) and Smart Energy Optimizer (SEO) customers* is:
|Annual emissions at default emissions rate (MT CO2e):||299.26|
|Less annual emissions from battery charging (MT CO2e):||71.32|
|Annual emissions avoided using default (MT CO2e):||227.94|
Annual emissions avoidance of 227.94 is the equivalent of taking 50 internal combustion vehicles off the road.**
*Based on 259 current program customers
**The EPA estimates one car to emit 4.6 MT CO2 per year.
SMUD’s Commitment to Operate Program launched in July 2018 and today, 85% of SMUD customers with battery storage are enrolled in the program. The Commitment to Operate Program requires participants to use 51% of their battery capacity to meet electrical needs during peak hours, 5-8 PM. That means customers can reserve 49% of their battery capacity for back-up power in case of an outage.
Ensure you meet program requirements
If you have a Tesla App, follow these steps to make sure 51% of your battery capacity is meeting your electrical needs during peak hours, 5-8 PM in summer months.
1. Open the Tesla App and select "Powerwall"
2. Select "Customize"
3. Select "Advanced"
4. Under 'Choose your setting' select "Balanced"
5. Update 'Reserve for Power Outages' to 49%
6. Select "Edit Price Schedule"
7. Select "Week"
8. Change 'Peak Hours' to 5-8 PM in summer months (June-September)

Did you know we launched a new battery storage program last year? SMUD’s Smart Energy Optimizer Program takes the hassle out of operating your battery. LG Chem batteries paired with a SolarEdge inverter are eligible for this program.
We'll optimize your battery to our Time-of-Day rates so you maximize savings on your electric bill. Occasionally, SMUD will also use day-ahead price signals to optimize devices to consume more renewable energy or lower cost energy. This type of optimization allows you to take advantage of lower rates without giving up comfort. The best part is, you still have 49% of your battery capacity available for back-up power needs.
