Meter-mounted devices: A meter-mounted device (MMD) is a customer-owned extension of the meter socket installed between the meter socket and the company’s meter that allows for the connection of emergency generation, solar generation, whole-house surge suppression, etc. The MMD form included in the Customer Generation application needs to be uploaded to be considered.

Please note: PacifiCorp does not plan to approve or adopt the new ConnectDER meter‑mounted devices that contain a “5” in the third character position of the part number (e.g., C‑B‑5‑22‑80). These devices do not meet our current technical requirements. Specifically, PacifiCorp does not permit the use of 5‑jaw meter mounts, and introducing equipment designed to operate with both 4‑jaw and 5‑jaw configurations could create confusion within our service territory.

We are actively engaged in communication with ConnectDER regarding this matter.

Specifications: Effective October 1, 2025, all new inverter-based Customer Generation applications will be required to use the provided settings. There have been slight changes made to the original settings dated June 1, 2024.

Specifications: Effective June 1, 2024, all new inverter-based customer generation applications are required to use UL 1741 SB certified inverters along with provided settings. These inverters meet the IEEE 1547-2018 standard for the interconnection of distributed energy resources.

Washington Schedule 135 Net Metering Service: Pacific Power customers in Washington have connected a threshold of 37.2 megawatts of generation capacity through Schedule 135. As a result, Pacific Power anticipates that a new customer generation program tariff will be available to customers in the near future. In the meantime, Pacific Power is still accepting customer applications for Schedule 135.

On September 5, 2025, PacifiCorp filed for approval of Schedule 138, net billing service, which the company proposed as a successor program to Schedule 135, net metering service.

Pacific Power has proposed that current net metering customers and customers who submit a completed interconnection application to the Company on or before the close of business on December 1, 2025 (or a later effective date based on Commission approval) may choose to remain on the net metering program.
