Transmission and Distribution
CBED Transmission Study, What did we learn?
How to using Transmission Maps & Tables
TRANSMISSION &
DISTRIBUTION LINES
ELECTRICAL TRANSMISSION
AND DISTRIBUTION SYSTEM
TRANSMISSION LINE
CHARACTERISTICS




Connects generation to load to bring power to
load centers. (See FERC Seven Factor test).
Transfer power across state lines and across
control regions.
115 kV and above Federally
regulated.
Lower voltage can serve
electric customers and/or
wholesale power market.
500 kV distribution line
DISTRIBUTION LINE
CHARACTERISTICS




Voltages are < 100kV, typically at or below
34.5 kV.
Primarily bring electricity
to customers.
Traditionally, power flows
into the line but not out.
State regulated system.
12.5 kV distribution line
ELECTRICAL SUBSTATIONS
Transmission Planning Zones
DISTRIBUTED GENERATION




Generation sited at or near load, “behind the meter.”
Typically connected to the distribution system.
Differing ownership
structures possible.
State definition
is 10 MW and
under.
DISTRIBUTED RESOURCES

Includes distributed generation and “demand
side” strategies such as conservation,
efficiency, and load management.
DISPERSED GENERATION




“Stand alone” generators not at existing retail
customer sites.
100 % of output injected into the grid.
No size limits, current DOC study looking at
10-40 MW sizes.
Can be connected to either distribution or
transmission lines.

additional power lines
WHAT THE C-BED STUDY
LOOKED AT



Analyzed thermal line loading and voltage
levels for 800 MW and 1400 MW of
Dispersed Generation at 21 locations.
Generation used to reduce Minnesota natural
gas power plant output.
Analyzed transmission system constraints
and established costs for fixing thermal and
voltage problems.
STUDY RESULTS

$49 M in transmission fixes.
$ 97 Million in transmission fixes.
No major new power lines were
needed.

Performed by: Wind Utility
Consulting for the Colorado
Governor’s Office of Energy
Management and Conservation and
the Department of Energy’s Wind
Powering America program
Year: 2005
Location: Highline Electric
Association distribution grid NE
Colorado
Results showed that 63 GE 1.5 MW
wind turbines or 94.5 MW of wind
could be incorporated into the
distribution system
Shows Red Willow Substation
with 4 turbines at a maximum
distance of 5.5 miles from the
substation.
