Energy: usage data.
Summary
Existing law requires each utility, on and after January 1, 2017, to, upon the request and authorization of the owner, owner's agent, or operator of a covered building, as defined, deliver or otherwise provide aggregated energy usage data for a covered building to the owner, owner's agent, or building operator, or to the owner's account in the ENERGY STAR Portfolio Manager, as specified. This bill would authorize a utility to satisfy that requirement by delivering or otherwise providing aggregated energy usage data to the owner's account in any alternative system or tool approved by the State Energy Resources Conservation and Development Commission.

MINOR
No substantive policy changes were made between these two versions of SB 500. The diff reflects only a change in presentation format: the formal chaptered document layout (with headers like 'STATE OF CALIFORNIA' and 'AUTHENTICATED ELECTRONIC LEGAL MATERIAL') was replaced by a web page rendering that includes navigation menus, bill tracking tools, and reformatted text. The actual legislative language of Section 25402.10 is identical in both versions.
TECHNICAL
The bill text was reformatted from a formal chaptered document layout into a web page display with navigation elements (home, FAQ, feedback, sitemap, login), bill search interface, version history list, and tracking features. No changes to the statutory language itself.
