A. SCE did not deem it necessary to establish different minimum usage eligibility requirements per customer. The 1.5 kWh minimum usage eligibility requirement is an accurate metric for A/C usage and is conservatively set by only requiring customers to meet the threshold once per calendar year in the hour before or after, during SDP event periods. If customers do run the A/C in the hour before or hour after an event, meeting the 1.5 kWh usage threshold should not be an issue.

A. Air Conditioners are not individually metered and therefore, SCE must rely on whole house usage data to evaluate performance towards the minimum usage eligibility requirement. SCE considers this fact to have no negative impact on customers regarding evaluating performance towards the minimum usage eligibility requirement.

A. No, only the A/C compressor will be shut off. The rest of your home will still have electricity and your indoor fan will still operate.

A. An Edison SmartConnect® meter enables SCE to evaluate your performance on the program by accessing at minimum, your hourly usage data during SDP event periods. To continue to participate in the SDP program, customers must meet the new minimum usage requirement established in 2017. The Edison SmartConnect® meter also enables SCE to verify valuable energy reduction during SDP event periods and it can provide SCE with information to help determine whether our load control device or your A/C are not functioning properly.
