As with any other interconnection project, the generating account meter must be capable of measuring the excess generation exported to the grid in 15-minute intervals. Once your interconnection request is submitted, SCE will determine if the correct metering is in place for the Solar Billing Plan. If needed, we will set up proper metering. 

Exported energy is allocated to multiple accounts ("Benefiting Accounts") that are located next to a property with a generating system.

• Energy exports are converted to monetary credits based on the Avoided Cost Calculator (ACC).
• Credits are used to offset energy charges, which are based on the benefitting customers' energy usage and rate plan pricing.  

The Solar Billing Plan Aggregation program has been available effective, February 15, 2024.  

If you have multiple electric accounts on the same property as the renewable generator or the properties are contiguous or adjacent, you can install a generator up to the aggregated load of all accounts, so long as all the properties are solely owned, leased, or rented by you. You must also be the customer of record on all SCE accounts. 

If you have an existing GMA and the combined system size is less than 15.6 kW, you can still use your existing GMA. However, if the new combined system is greater than 15.6 kW, the GMA cannot be used, and the new array must be connected to the service panel through a load-side connection. 

Yes, the GMA is SCE-owned and becomes part of the metering services. However, the neutral pigtail is the white wire included in the GMA. SCE makes the connections to the GMA, including the Neutral to the customer’s panel. If needed, the Contractor may assist with the Neutral. 

DA and CCA customers are eligible to participate in the Solar Billing Plan if the Energy Service Provider (ESP) or CCA agrees to support the provisions of the Solar Billing Plan. The ESP or CCA must provide their agreement to support these provisions before your associated accounts can/will be placed on the Solar Billing Plan. SCE will be responsible for delivery credits (if applicable), and your ESP or CCA will be responsible for any corresponding generation credits. DA and CCA customers are not eligible for Net Surplus Compensation from SCE. 

If your ESP or CCA declines to support the Solar Billing Plan, you have a few options:  

• You may choose to remain with your service provider, continue service without the benefits of the Solar Billing Plan, however you will still receive the usage reduction benefit from the system.  
• You may choose to switch to a different ESP that offers the Solar Billing Plan.
• You may choose to return to bundled service.

Where CCAs and ESPs have their own renewable programs, they still must go through our interconnection process and receive Permission to Operate their generating facility from SCE.  

If a customer terminates service or experiences a change from SCE Bundled Service to CCA or DA Service (or from CCA or DA Service to SCE Bundled Service), the 12-month Relevant Period will end on the date when the change of service is effective.  

Note: SCE cannot speak for the ESP or CCA and cannot discuss the ESP’s or CCA’s reason(s) for declining to support the Solar Billing Plan or Solar Billing Plan Aggregation. If you have any further questions, please contact your ESP or CCA. 

For billing inquiries please contact SCE Customer Service at 1-866-701-7868 for residential customers or 1-866-701-7869 for business customers. 

There are several ways you can minimize the electricity you receive from SCE to supplement your solar generating system. The best thing you can do is be mindful of the time of day and weather – your system won’t be generating when it’s dark out, and it will produce less when there’s cloud cover. Even small changes can make a difference to your bill. We’ve listed a few recommendations below to help you make the most of your solar-produced power:

• Consider investing in a battery storage system to keep more of your self-generated energy for use at night.
• Shift major appliance and equipment use (like a pool pump or washer-dryer) to off-peak daytime hours (8 a.m. - 4 p.m.) when your solar generating system is active.
• Try not to use too many appliances simultaneously during the day, so your system can keep up.
• Periodically have your solar panels professionally cleaned.

Remember that if you make changes or investments like buying electric vehicles or installing a pool, your energy consumption will increase. If your system was not sized with these investments in mind, you’ll either need to upgrade your solar generating system or use more energy from SCE.

You can view your usage history by logging in to My Account. You’ll be able to see both the energy you’ve consumed from the grid, as well as the excess energy you’ve generated. Reviewing your usage history can help identify when to shift your energy use, which can have an impact on your bill. 

You may elect to change the start date of your 12-month Relevant Period once only for the lifetime of the account, by completing and returning a One-Time Relevant Period Change Request Form (14-936).

You will be responsible for selecting the date of the requested change. We must receive this form at least 60 days before the requested start date of the new 12-month Relevant Period. When the start date is changed, your existing 12-month Relevant Period will end, generating your settlement bill, and your new 12-month Relevant Period will begin. Under no circumstances will a 12-month Relevant Period extend beyond 12 months. 

Over the course of your 12-month Relevant Period, Energy Export Credits (EEC) will be applied to the amount of electricity a customer exports to the grid and will reflect the electricity’s value to the electric grid during each hour of the day. Energy Export Credits will be calculated by taking the kilowatt hours generated by the customer’s generating system that is exported hourly to the grid multiplied by the Energy Export Credit prices. These EEC prices will vary hourly throughout the day and can be found here for both Pacific Time and Universal Time. Customers who enroll in the Solar Billing Plan before January 1, 2028, will have fixed EEC prices for the first nine years of operation. The nine years is referred to as the lock-in period.

Each year, the EEC Prices are calculated using the CPUC Avoided Cost Calculator (ACC) approved as of January 1 of the calculation year (the “vintage year”). For each “vintage year”, the simple average EEC Price is calculated for each month of a 9-year lock in period, and it is differentiated by hour (24 hours) and by weekdays and weekend/holidays. In addition, each hourly EEC Price is broken down in two components: (1) the Generation EEC Price (energy, cap and trade and generation capacity) component, and (2) the Delivery Service EEC Price (transmission, distribution, greenhouse adder and methane leakage) component.

At the end of your 12-month Relevant Period, if you have supplied more electricity than you have used, you may be compensated with an on-bill credit or a check for the NSC paid at the market rate.  

Once the NSC is calculated and issued to the account holder, the balance will be zeroed out and the new 12-month billing period will begin on the next regularly scheduled meter read date.
