CA AB1879

Requires the Public Utilities Commission to reconsider Decision 86-06-035, which established a 3-year retroactive billing limit for commercial customers of gas and electrical corporations for meter and billing errors.

Mandates the Commission open a proceeding by January 1, 2011 if it has not already reconsidered the decision to examine whether the 3-year limit is appropriate specifically for small commercial customers.

Notes that Decision 86-06-035 applies the same 3-year retroactive billing limit to both small commercial and large commercial customers, without distinction between the two.

Establishes that residential customers currently have a 3-month retroactive billing limit under the existing decision.
