Description
These projects are primarily driven by the need to upgrade the transmission system based on meeting NERC
standards or Ameren Planning Criteria and Guidelines. The NERC TPL standards set forth a set of tests that a
transmission system must meet for a list of plausible scenarios, including contingent scenarios. Ameren Planning
Criteria and Guidelines (C&G) are filed each year at FERC and constitute an additional, or complementary, set of
tests that the transmission system must meet.
These projects are primarily driven by the need to upgrade the transmission system to support expected flows
on the transmission circuits. Load growth, plant additions/retirements, and flow changes due to future system
expansions are primary inputs into the decision to either increase ground clearances using existing wire or in
some cases, increasing ground clearances with wire replacement, in order to achieve higher circuit ratings.
These projects are driven by the need to increase the rights and rights-of-way associated with 40 transmission
corridors. The primary benefit of this set of projects is increased reliability of the system in the area of
vegetation. In many cases, the existing rights-of-way are much narrower than the widths specified in Ameren's
Planning Criteria and Guidelines for reliable circuit operation. The 2003 blackout and the recent 2011 Northeast
US major outage event had vegetation as an incipient cause. After both events, and with the adoption of the
FAC-003 standard, FERC has emphasized the need for increased vegetation management efforts which these
projects support.
These projects are driven by the need to address reliability concerns driven by system topology, configuration,
or condition. Operating issues, including outages, usually identify these kinds of projects. The majority of these
projects involve additions of equipment in substations, e.g. relaying and/or circuit breakers.
