California ISO Enters New Era of
Jan 24, 2007 Business Wire
The California Independent System
Operator Corporation (California ISO) has entered
a new era of transmission planning with a comprehensive
plan that examines what California's power grid
will need one to three years from now to ease bottlenecks
and enhance reliability and what will be needed
in five to 15 years to keep up with the expected
growth in energy supply and demand.
The Transmission Plan is a living
document that will grow and evolve over time. It
is a collaborative effort that includes the work
products of the California ISO, its Participating
Transmission Owners (PTO), the California Public
Utilities Commission (CPUC), the California Energy
Commission (CEC) and many other stakeholders.
California ISO President and CEO Yakout
Mansour said the Transmission Plan is akin to a
general plan used to guide growth in a booming city
or county. "In the past, we have allowed growth
to occur on a project by project basis without really
having a plan of what we want the larger community
to look like. This plan is the blueprint that tells
us where we need new infrastructure and how we're
going to meet California's growing electricity needs
in a coordinated and comprehensive fashion."
The Transmission Plan, available on
the California ISO website, highlights 160 different
transmission projects--53 scheduled to go on line
in 2007--that are or may be needed to enhance reliability,
access new generation, deliver renewable resources
and reduce bottlenecks on the grid. Some of the
major projects approved or being studied include:
Tehachapi, Sunrise Power Link, LEAPS, Trans Bay
Cable, Midway-Gregg, and the West Coast Cable Project.
The Transmission Plan began with the
CEC, CPUC and the California ISO discussing how
the three agencies could leverage their core strengths
and ensure resource planning, procurement and transmission
planning are coordinated, streamlined and aligned
with state and federal policies. The end result
of that effort is the Integrated Planning Process.
The California ISO Transmission Plan is one piece
of that larger endeavor.
The Integrated Planning Process was
developed to ensure that key information on transmission
costs and feasibility are provided to the CEC, CPUC,
resource developers and Load Serving Entities in
a timely fashion. Likewise, information on resource
plans and procurement needed for transmission development
is provided to California ISO and the PTOs. The
process is intended to fully coordinate the individual
proceedings and processes of the CEC, CPUC, and
California ISO, allowing all stakeholders, including
Publicly Owned Utilities (POU) to participate.
The California ISO is a not-for-profit
public benefit corporation charged with managing
the flow of electricity along California's open-market
wholesale power grid. The mission of the California
ISO is to safeguard the reliable delivery of electricity,
and ensure equal access to 25,000 circuit miles
of "electron highway." As the impartial operator
of the wholesale power grid in the state, the California
ISO conducts a small portion of the bulk power markets.
These markets are used to allocate space on the
transmission lines, maintain operating reserves
and match supply with demand in real time.
