So
where does Baldwin City actually get its electricity from?
Baldwin
City has a diverse mix of generation types in our portfolio
including, Coal, Natural Gas, Diesel, Wind, and Hydro.
We
purchase about 74% of our wholesale energy from the Grand River Dam
Authority, 12% from the Marshall Wind Farm, 5% from KCP&L, 5%
from the Western Area Power Administration, 3% from the Spot Market,
and the remaining 1% comes from the Southwest Power Administration
and In-House Generation.
KCP&L
also supplies Baldwin with use of their transmission lines to import
power from the purchase agreements listed above.
I
thought Baldwin City had a Power Plant?
Baldwin
City does own and operate two generating plant’s, however, the cost
of producing power internally is significantly higher than purchasing
energy through our wholesale agreements.
For
example, the average cost year to date of purchasing power through
our wholesale contracts listed above is $.0484 cents per Kilowatt
Hour.
In
Comparison, our In-House generation while running on natural gas
comes in at around $0 .0670 cents per kilowatt hour. When the units
are running during an outage, or an anticipated outage, they use
straight diesel at cost of $0.2049 cents per kilowatt/hour.
So
when do you run the Power Plant?
Baldwin’s
generators are not base load units, they are peaking units designed
to shave peak load during high use times, and can be utilized as
emergency back up during times when we lose power from the KCP&L
tie line. This doesn’t mean they can’t run for extended periods
of time; however the associated cost as shown above prohibits this.
Baldwin’s
generation and how its’ utilized has evolved through several
decades of load following contracts with KCP&L. Today we operate
in the “Day Ahead” or “Day 2” market. Our newest units (7 &
8) located at Power Plant # 2, are registered with the Southwest
Power Pool. SPP now oversees the entire transmission and distribution
grid in our area, and is the dispatching authority over all
registered power plants within their footprint.
Baldwin
units run when directed to do so by SPP, however, we can
self-schedule ourselves anytime for testing or during an emergency
situation.
SPP
has capacity and heat rate data on each of the registered generating
units including large coal or gas plants like KCP&L, right down
to the peaking units like Baldwin’s 7 & 8. They know what each
unit is capable of producing and the associated cost. SPP will
dispatch units based on hourly loads as well as forecasted peaks for
the day ahead.
Does
Baldwin sell the power it generates in the open market?
Baldwin
City does not generate power to sell in the open market and never
has.
Past
contracts with KCP&L allowed us to sell off excess BPU Nearman
energy when it was available, and we have sold excess capacity to the
City of Gardner in past summers, but NONE of the energy generated by
Baldwin units ever leaves the City limits.
Why
don’t we staff the plant 24/7?
The short answer is economics. Baldwin City currently has 2 plant operators that maintain and manage both power plants.
In
the 1980’s, Baldwin had 8 power plant operators and was staffed
24/7. Through the 90’s and early 2000’s, many of the original
plant operators retired and were not replaced, as there was no longer
a need for round the clock plant coverage.
Baldwin’s
electric utility has gone through other significant changes over the
years as well. We now have two primary feeders that can supply
Baldwin’s electric load from two different directions; West
Gardner, and/or South Ottawa. This greatly reduces the risk of losing
grid power for extended periods of time.
Last
weekends’ outages were a prime example as the West Gardner Feeder
was damaged due to several broken utility poles. KCP&L placed
Baldwin City on the South Ottawa feeder until the repairs could be
made.
Takeaways
Baldwin
City is a Municipal Owned Utility. It exists to provide a public
service to the citizens by way of long-term community goals,
local
control, local regulation, and higher standards of reliability.
Municipal
utilities are located within their community and are readily
available to serve customers. Local ownership means that customers'
utility dollars stay in the community, creating jobs and supporting
the local economy.
