Questions answered by the public record
Does SDG&E own Ramona Solar Energy?
Yes. Ramona, also known as the Creelman Project, is SDG&E utility-owned solar generation developed under the CPUC Solar Energy Project program. Its engineering and permitting role is attributed to Independent Energy Solutions; the compliance report does not identify the defaulting EPC contractor by name.

Why are several capacity ratings shown for Ramona?
The page’s 4.3 MW is EIA nameplate capacity. SDG&E’s compliance report separately reports 4.32 MW CEC-ac and 4.95 MWdc. These are different AC/DC and rating conventions. The latest August 2026 EIA workbook lists 4.9 MW DC net capacity; these values should retain their source and measurement labels.

When did Ramona begin commercial operation?
SDG&E deemed commercial operation effective April 1, 2017, after the facility began delivering full output in March. Remote monitoring began April 21. EIA lists April 2017 as the operating month. Contractual substantial completion and remote monitoring are separate milestones.
