Mid-August Reservoir Update.

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.

Early August 2019

Generation update for early August: Juneau remains in a drought per the National Weather Service, and our reservoir levels are slightly below where they would normally be this time of year. Right now our dual fuel customers and Princess Cruise Lines are being served with hydro power, and Greens Creek is on partial hydro power.

We continue to monitor our reservoir levels closely, and will adjust service to interruptible loads as necessary. The climate prediction for the remainder of August is for drier than normal weather.


Mid July 2019

As of mid July, Juneau has returned to a Moderate Drought designation. The National Weather Service shows the outlook for August - October as equal chances of above or below normal precipitation. Overall, the Juneau area reservoir levels are slightly below normal for this time of year.

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.


Early July 2019

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.


June 2019

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.
