PG&E’s ReMAT Appendix E Guidelines Facility Description The facility description is intended to be a narrative description (not to exceed 1 page) that includes a summary of the major components and attributes of the Facility. Please make sure to include the following:

Name and address of the Facility Parcel numbers (APNs) that are part of the Site Latitude and Longitude of the centroid of the Site Existing land use Capacity - MWAC and MWDC Transaction: Full Buy/Sell or Excess Sale Brief Renewable Resource/Technology description:

o e.g. Solar Photovoltaic (Single axis tilt, poly-crystalline); Biogas generation (cattle waste digester); Biomass (woodchips); Hydroelectric (run-of-river)

Interconnection Point – Substation name and circuit number. Interconnection voltage Estimated Interconnection Commercial Operation Date Any known discrepancies among Appendix E documents should be explained in

the Facility Description A table of major components with technical descriptions:

Solar PV Equipment Description PV modules Wattage, type, manufacturer Inverters Capacity, manufacturer Step-up transformer Capacity, voltage levels Project Substation Transformer (if applicable)

Capacity, voltage levels

(other)

Biogas – Generation Equipment Description Digester Lagoon Size (gallons or acres) Engine Number, type, manufacturer Generators Type, manufacturer, capacity Transformer Capacity, voltage levels (other) Biomass Equipment Description Boiler Turbine Generator Type, manufacturer, capacity Transformer Capacity, voltage levels (other) Hydro - Generation Equipment Description Turbine/Penstock Type Generator Type, manufacturer, capacity Transformer Capacity, voltage levels (other) Facility or Equipment Layout Drawing (may overlay Site Map) The Facility Drawing must illustrate the general layout of the facility. Please include the following:

Relative positions of the project’s major components. Voltage related to interconnection and the point of the interconnection.

Site Map (may overlay with Facility Drawing) The Site Map must include the following:

A clearly labeled perimeter of the Project Site (i.e. site control boundary). Clearly labeled nearby roads, including the nearest intersection. If the primary site map is too close to display the nearest intersection, please also

provide a supplementary map at a larger scale so that nearby roads and landmarks can be seen.

Single Line Diagram The Single Line Diagram must illustrate internal equipment and connections as well as the components for interconnection of the Facility to PG&E’s electric distribution system. At minimum, please include information for the following components:

Name and address of the facility. These should match what is in the PPR. Electrical system components, cabling and connections for all AC and DC

systems with associated labeling (voltage levels, AC or DC, overhead or underground, etc). For solar PV projects, each typical solar array must be shown or described.

Generators and/or inverters (including capacity and voltage designations) Transformers – for generation system and/or interconnection and station power

(A station service transformer is for the generating facility’s station use and must be on the project’s side of the meter.)

Metering (e.g., CAISO revenue meters and/or Utility meters) Fuses and Breaker Disconnects and/or switches All other switchgear.

Common Issues

• Facility name in PPR does not match what is provided in Appendix E docs • Facility address in PPR does not match what is provided in Appendix E docs • Equipment and related details are inconsistent among the various Appendix E

docs • Mismatch in project size or other major details with Interconnection Study

Key Takeaways

• In the event that the PPA is executed, PG&E will expect the as-built drawings to be exactly as described in the PPR.

• Refer to the Re-MAT instructions when preparing your documents • Label everything and err on the side of inclusiveness • Pay attention to the details. We look at these documents very closely
