In 1992, the federal government allowed regional operators, like the California Independent System Operator, to take over operating transmission lines that were run by investor-owned utilities. Before this quasi-governmental agency was developed, Southern California Edison, San Diego Gas & Electric, and Pacific Gas & Electric (as well as federal and other state utility operators) had to phone each other to transfer electricity on transmission lines that were physically connected, but operated separately. \tAfter a decade, and the 2000-01 energy crisis, the grid operator found its groove. \tIts mantra has been \u201cmore is better.\u201d That is, as Sen. Rod Wright (D-Inglewood) has been quoted\u2014we paraphrase\u2014\u201cThe ISO\u2019s never seen a project it doesn\u2019t want developed.\u201d Lines are rarely decommissioned, apart from when they are replaced as a part of an upgrade project. According to CAISO, the process to decommission a line involves the owner utility notifying the grid operator and requesting to have a line removed from its operational control. The grid operator decides whether the line is useful. \u201cIf we agree the line is no longer needed, we are required to post a notice on the website and allow external stakeholders time to comment and dispute our findings. If after reviewing all comments (if any) we will make a final decision to either remove the line from ISO control or keep it,\u201d according to the CAISO. The funding mechanism for retiring transmission lines is separate and apart from the nuclear power plant decommissioning trust fund. The cost of transmission retirement is collected through the transmission investment recovery rates authorized by the Federal Energy Regulatory Commission. Specifically, that is done via the accelerated depreciation rate that accounts for removal costs, according to the Division of Ratepayer Advocates. FERC has oversight of transmission line cost recovery and the cost for transmission service is reflected in the Transmission Access Charge in ratepayers\u2019 electric bills. That cost is $8\/MWh now, and is expected to be $13\/MWh as the transmission system is \u201cbuilt out,\u201d according to Steve Berberich, grid operator chief executive officer.
