Cost of Power Adjustment charge to decrease in 4th quarter to $0.018916
Interruptible sales in the 3rd quarter contributed to the decrease.
Reservoir levels are below normal - Greens Creek, Princess Cruise Ships and Dual Fuel customers are disconnected.
Striking the right balance between conserving water for future use and selling surplus energy, which provides a cost reduction to customers, is something we continuously reevaluate and adjust. Forecasting precipitation isn’t an exact science. We consider forecasts from multiple sources, including NWS/NOAA in helping to determine the best course of action.
Reservoir levels need to improve significantly before the interruptible loads can be reconnected.
By the numbers: Normal precipitation at Snettisham for July, August and September is 46.94 inches. To date this year, Snettisham received only 17.47 inches for that same period.

Even with the rain we received over the prior weekend, our reservoirs are still lower than normal for this time of year. Precipitation is still below normal for the water year and a few inches below last year. Snettisham precipitation for the month of August was 5.68 inches below normal.
All Interruptible customers are disconnected until our reservoirs return to normal levels.
With little precipitation this month, the reservoirs have not filled as quickly as normal. Water year to date is now both below normal and below last year. Greens Creek, Princess Cruise Ships and Dual Fuel customers will be disconnected and will generate with their own power or heat with an alternate fuel source.
Striking the right balance between conserving water for future use and selling surplus energy, which provides a cost reduction to customers, is something we are continuously reevaluating and adjusting.
As we know, forecasting precipitation isn’t an exact science. We consider forecasts from multiple sources, including NWS and NOAA in helping to determine the best course of action.
We will continue to monitor reservoir conditions and adjust accordingly. Normal precipitation this fall is needed to reconnect interruptible loads.
By the numbers: Normal August precipitation at Snettisham is 14 inches. September is 25 inches. August precipitation to date at Snettisham is measuring less than one inch.

As of the end of June, the Juneau area has been downgraded from a Moderate Drought back to Abnormally Dry.
The Juneau area reservoir levels are currently near normal for this time of year and are expected to continue to be unless late summer/fall precipitation is below normal as it was in water year 2018.
Currently, all customers are on hydro. Dual Fuel and Princess Cruises are being served with 100% hydro. Greens Creek is taking partial hydro from us and running their own generation in parallel.
Although drought conditions continued throughout the spring in Southeast, lake levels improved slightly which allowed us to begin serving interruptible loads. As a result, the 3rd quarter Cost of Power Adjustment decreased slightly to 2.28 cents per kWh, effective July 1. Also, lower summertime rates are in effect from June to October. For residential customers, this means a 2.06 cent decrease per kWh on their bills in addition to the slight reduction in the COPA rate.
It’s important to note that the recent rainfall in Juneau does not always mean equal precipitation at Snettisham, where two-thirds of our energy comes from. For example, precipitation at Snettisham is 87% of normal, compared to Juneau precipitation which is 98% of normal for water year to date.
We have created the Generation Report below to keep customers informed on our current generation status. The graphic below shows where we are as of June 2019. As always, we are available to answer any
questions or concerns. We can be reached at 780.2222 or by visiting the Contact Us page.
