Deployment of RATES

Focus on medium and larger retail customers with flexible technology:

• electric heat pumps, electric water heating, pumps, battery storage, solar, electric vehicles & commercial refrigeration.

• California’s 100 percent clean energy and electrification goals will result in many customers with these technologies.

Load serving entities (incl. CCAs) and distribution operators implement:

• automated interfaces to RATES, and• the Subscription Transactive Tariff on an opt-in basis by the customers with flexible

technologies.

Tailor to each customer’s situation:

• 5-, 15-minute or hourly metering, • with or without HAN interface to the facility meter, and• with or without automated energy management systems and forward transactions.

Benefits of RATES

TeMix Inc. 11

Highly dynamic tariff prices enable more

flexibility for renewables than static

TOU tariffs

Simple, granular tariff; No demand charges, DR events, capacity

payments or DER baselines

No need for DER to bid into wholesale

markets and be dispatched

Forward tenders support optimization of storage, EVs, HVAC, electric water heaters,

and pumps

Subscriptions support low income policies and can retain net

metering solar benefits

Lower IT, settlement and program costs
