My electric bill for November is huge! What’s going on? Why
do you charge so much more in the winter when people need
more electricity? |
|
| |
|
|

As strange as it sounds,
AEL&P charges more in the winter to keep overall rates lower
for everyone. Here’s how it works. We have two rates for
electricity: A summer rate, for energy billed from June 1
through October 30; and a higher winter rate, for energy
billed from November 1 through May 31. Seasonal rates have
been part of AEL&P’s rate structure for over 25 years, and
are approved by
the Alaska Regulatory Commission.
We see our peak energy use
in the winter, and the higher this peak is, the more AEL&P
has to spend (and the more money we have to collect from our
customers) for larger transformers, additional generation
capacity, etc. A higher rate in the winter sends a price
signal for all electric users, particularly those who use a
lot, to conserve what they can. The lower we can keep the
winter peak through the conservation of electric users, the
lower we can ultimately keep our rates. |

I know the rates go up
in November, but this year they went up much more than
usual. Why is that? |
|
| |
|
|
| |
The reason the increase
was particularly high this fall has to do with the "power
cost adjustment" included on each electric bill. Our rates
are set to cover our costs, but there are some things that
change often, so we include them as a power cost adjustment.
For example, energy that is
surplus to the needs of our regular customers can be sold to
Princess Cruise Lines or Greens Creek mine. Almost all the
revenue from these "surplus sales" is refunded back to our
customers in the power cost adjustment. If you look at your
bills from the past summer you will see a rebate of more
than 5% due to these sales.
The power cost adjustment
is also used when we run short of water to generate hydro
power and need to supplement that with diesel generation. In
this case, the power cost adjustment is charged to our
customers for their share of the cost of the diesel fuel we
will need this winter to meet our demand.
The November adjustment
included a 15% surcharge for the cost of the diesel we will
use this winter because our reservoirs are so low.
Unfortunately that adjustment from a rebate to a surcharge
happened in the same month as we changed from summer to
winter rates, causing our customers to see a much larger
than normal total increase.
Fortunately this situation
is temporary. The power cost adjustment is revised every
June and November. |

The reservoirs are low?
How can that be with all the snow and rain we experienced
this past year? |
|
| |
|
|
| |
The water level in
the reservoirs depends on how much water flows in from rain
and snowmelt, and how much water is taken out to generate
power. As you can see from the graph, Juneau’s demand
for electric power has recently exceeded our hydro capacity.
We now need
more electricity than we can generate with hydro even in a
normal water year. |

Well, if we are running
out of water to make our hydroelectric power, why are you
selling energy to the Greens Creek mine? |
|
| |
|
|
| |
We reserve our hydro
resource for the homes and businesses of Juneau. If we have
more hydro than we need in town, we sell it to Greens Creek
and rebate most of the revenue from those sales back to our
customers. This water would just spill over the dam and be
lost if it wasn’t used to generate electricity.
A small amount of power was
sold to Greens Creek this June and July as the record
snowpack melted and large amounts of water flowed into the
reservoirs. In August, when the weather began to dry, we
curtailed surplus energy sales to Greens Creek in order to
save the hydro energy for our other customers. No energy is
being sold to Greens Creek at this time. |

If we are running out
of hydro energy, why don’t you build a new powerplant? |
|
| |
|
|
| |
We are! We began
permitting for the next hydro project, the Lake Dorothy
Project, in 1996, and began construction in 2006. Lake
Dorothy is expected to be on line in late 2009. That will
bring us back to a hydro surplus position and remove the
need for diesel generation for some time. |

Is there anything I can
do to lower my electric bill? |
|
| |
|
|
| |
Conservation always
reduces energy use and results in lower bills. Doing things
as simple as turning off lights or appliances when not in
use helps. Better insulation and weather stripping can
reduce heating costs. Replacing incandescent bulbs with
compact fluorescent ones can also save energy and lower
bills. Using a fuel other than electricity to heat your home
will also minimize our diesel generation. |
