What is included in the CPS Energy distributed generation (DG) manual?

Please note that the CPS Energy Distributed Generation (DG) Manual is currently undergoing revisions to include Battery Energy Storage Systems (BESS), Microgrid, other DG Resources (DGRs), and ERCOT DGR interconnection requirements.

What is a distributed generation (DG) facility owner?

The Distributed Generation (DG) Facility Owner (Owner) shall design, operate, and maintain the DG as required for interconnection of the Owner's DG system with CPS Energy's system. This Appendix describes typical requirements for installing/interconnecting DG Facilities to the CPS Energy system.

When will CPS Energy reconnect its power system to the DG owner?

CPS Energy will consider reconnecting its power system to the DG Owner when CPS Energy has evidence that the electric energy of the DG Owner meets the Standards and Requirements of Section 2.2 - Prevention of Interference and Table 1 - Interference Limits for DG Systems Applied by Difference Entities.

Do distributed generation systems cost more per unit of capacity?

1 Distributed generation systems often cost more per unit of capacity than utility-scale systems. A separate analysis involves assumptions for electric power generation plant costs for various technologies, including utility-scale photovoltaics and both onshore and offshore wind turbines used in the Electricity Market Module.

What is distributed generation (DG)?

Distributed Generation (DG) - An electrical generating facility located within the CPS Energy service territory of less than 10 MWac and connected at a voltage of 35kV and below, which may be connected in parallel operation to the CPS Energy system.

How does CPS Energy approve a DG facility?

Once CPS Energy determines that the DG facility is suitable to operate in parallel with the CPS Energy Distribution System, both the DG Owner and the CPS Energy representative will sign and date the “Approval for Operation” document (Certificate of Completion).
