Retail electric rate schedule
Attached are graphs prepared,by Steve Hollabaugh that show our wholesale power
costs from now to the end of 2010.
Forward Mid-C Wholesale Power Prices 2001 through 2010: This graph shows the
market price of wholesale power in blue, and the price of our wholesale power in green.
Through 2003 our price is significantly lower than the market. After 2003 our price is at
or slightly above the market
TDPUD Power Supply Costs $/MWhr: This graph shows how our wholesale price has
increased from 2000 through 2009. In 2000 we were paying $35.35 per MWhr
(megawatt hour), which is the same as 3.535 cents per KWhr(kilowatt hour). In 2001 the
wholesale price went to 4.602 cents per kilowatt hour. In 2002 it will go to 7.054 cents
per kilowatt hour. Finally, in 2003 it will go to 8.25 cents per kilowatt hour.
So, in 2002 we will be paying an additional 2.452 cents for wholesale power. Our retail
rates will need to go up a like amount by January 2002.
The next year our wholesale power costs will go another 1.196 cents per kikowatt hour,
and our retail rates will again need to go up by that amount.
TDPUD Power Supply Costs $: This graph simply takes the prior graph, which is stated
in unit costs per megawatt hour, and converts the unit costs to gross dollars per year.
You get the idea that our power supply budget goes from $6.2 million in 2001 to $15.8
million dollars in 2009. The price we would pay for failing to keep our retail rates current
could be staggering.
Truckee Donner Forcasted Load and Resources, April 2002 - March 2003: This
graph shows our commitment to puchase power from Idaho in red, and our load in black.
The red area above the black represents our surplus power, which we will sell at market
prices. When the black spikes above the red we will be in the market buying power to
meet our loads.
Truckee Donner Forcasted Load and Resources, April 2008 - March 2009: This
graph is similar to the prior graph, except it convers the year 2008. It shows that we grow
into the Idaho contract, and in 2008 and 2009 we do not have much excess power to
sell. We will need to secure additional wholesale power toward the end of the Idaho
contract.

Review of retail rates: Our current residential retail electric rate is 6.811 cents per
kilowatt hour. By January 2002 it will need to be increased to 9.263 cents, and by
January 2003 it will need to be increased to 10,459 cents. By comparison, the current
PG&E residential rate is 13 cents per kilowatt hour and will be going up significantly.
However, the SPPCo rate is currently about 7.3 cents per kilowatt hour. They will need
to increase their rates significantly soon, but I do not know when.
It is easy for us to remain competitive with PG&E. We will remain competitive with
SPPCo in the long run, but in the short run we may not be.
I invite the Board to consider how to deal with electric rate increases.
1) We can phase them in steps.
2) We can redesign our rate structure to utilize assending block prices
3) We can increase the flat rate monthly customer charge
