There is broad support for majority of proposal, but a few concerns remain. • Topic 6: Southern California Edison would prefer fixed fee versus actual costs approach because of ease of administration • Topic 10: Large Solar Association would like self-prioritization mechanism for interconnection agreement negotiations Page 5
