SAHM WHITE on Behalf of CLEAN COALITION

SAHM WHITE on behalf of CLEAN COALITION

“Following up on a proposal raised by utilities in the Sept 30 meeting regarding proposed elimination of the example DER hosting capacities on the ICA maps, the Clean Coalition notes that Attachment A of the August 23rd Ruling specifically calls for the ICA to quantify the hosting capacity of representative portfolios of DER, and to display this information on the online map. (see below)

The current ICA map does include this information, which we believe is useful in providing a consistent indicative capacity for the example DER profiles developed by PG&E. We believe this information is required and is not a computational burden.

We do not support the proposal to eliminate the availability of this information through the map interface.

We do strongly support further discussion on how these profiles should or should not be used when integrating ICA results into the interconnection review and study processes, but that is a separate issue.

ASSIGNED COMMISSIONER’S RULING GRANTING THE JOINT MOTION 8/23/2016

Attachment A

1.3.4. Calculate ICA results and display on online map (p. A9)

..."The ICA maps shall be available online and shall provide a user with access to the results of the ICA by clicking on a feeder displayed on the map."...

1.4.3. Different Types of DER (p. A10...) a. The methodology shall evaluate the capacity of the system to host DERs using a set of ‘typical’ DER operational profiles. PG&E has developed a set of profiles that provide a starting point. These profiles are: o Uniform Generation o PV o PV with Tracker o EV – Residential (EV Rate) o EV – Workplace o Uniform load o PV with Storage o Storage – Peak Shaving o EV – Residential (TOU rate) b. ICA shall quantify hosting capacity for portfolios of resource types using PG&E’s approach with representative portfolios of i. solar, ii. solar and stationary storage, iii. solar, stationary storage, and load control and iv. solar, stationary storage, load control, and EVs.
