Daily commentary from AEL&P's Scott Willis regarding energy consumption:

2/2/09am: Diesel use was down over 25,000 gallons on Sunday because we turned off the diesel generators by 5:45 p.m.!

Note: don't be surprised if the total amount of diesel use reported over the next few days is a bit lower than the total shown on this sheet. The numbers I used here were an estimate, and I estimated just a bit high. I think our metered diesel use will be a bit lower.


2/1/09 - 5:15pm: Snettisham line repairs completed this afternoon. Power restored to town with about 14 minutes remaining in the fourth quarter...

2/1/09 - 1:55pm: I just heard from Eric. Repair crews were able to get on the mountain today. They still expect to finish their work today. If that happens, we have to do some switching to get Snettisham energy coming back to town. Once we have that we can begin the process to turn off the diesels.


2/1/09am: Saturday's energy use was lower than Friday, which is expected, but Saturday was even cooler. Energy use down nearly 2%, diesel use of 73,670 gallons, down more than 2,000 from Friday.


1/31/09pm: Repair crews had a good day Saturday. All three phases are spliced and suspended in the air. There is another day of work to finish making the connections at the towers. Weather permitting the job will be completed on Sunday. Once the repair work is complete the line will be switched back in and the diesel generators will be turned off. Maybe we'll get to watch the Superbowl with hydro energy!


1/31/09am: Energy use down another 1.7% Friday, and diesel down another 5,000 gallons. Loads were light enough that we didn't have to run some of our less efficient units.

The word at 8:00 a.m. was that repair crews were just heading out to the site. There needs to be a relatively small amount of avalanche control work to make the area they will be working in safe. The weather today appears to be a bit better than yesterday, so we are hoping for a productive day today. I think it is unlikely they will finish today, but should have less than a days work after today. We are also doing some switching in the system today to make it more convenient to bring Snettisham back on line when it is ready. We're getting close to completion.


1/30/09pm: The linemen made it up to the repair site this morning AND made it off the mountain this afternoon (though the weather wasn't the greatest in between times).  They were able to splice all three phases of the new wire to the existing conductors at tower 3/4. The remaining work is to measure the proper length and cut and splice the three phases at tower 4/1. That can be a time consuming process since it amounts to hoisting the wire into the air, lower it, splice it, and hoist it up again to make sure it is correct. So there may be a day and a half of work remaining.... when weather permits.


1/30/09am: Warmer temperatures, lower loads. Energy use down another 1%, diesel use down over 2,000 gallons since yesterday. Average temperature on Thursday was only 1 degree cooler than the day of the avalanche. Energy use was almost 10% lower than that day. This is a pretty good indication of the community's conservation since that time.

The weather has been up and down at Snettisham, as it has been in town. During an open window this morning the avalanche control crews were able to get all the way up to the top of the mountain. They discovered that with the warmer wet weather last night that natural avalanches had released.
They determined that the work site is safe for the repair crews today. Repair crews landed at the site this morning. They are working on the mountain. It is snowing on and off and the visibility is up and down, so the work is going more slowly than they would like, but they are at work on the site today. And that's good news.

1/29/09: Warmer weather Wednesday brought lower energy and diesel use. We used and estimated 83,656 gallons of fuel on Wednesday. Energy use was down another 2% from the day before.

Natural avalanches were heard in the Snettisham area last night. Avalanche control crews were able to fly up briefly this morning. Avalanches were being released just from the impact of the bomb hitting the snow, without even detonating. The avalanche danger is high, and control crews are unable to get up very high to assure that all potential avalanches are down. Repair crews are not on the mountain today. A lot of thought is being given to trying to find any way to finish the job without putting crews in the avalanche area. We haven't come up with anything else so far.  Very discouraging to be so close and not be able to finish the job.


1/28/09PM: There was a window this morning where the weather allowed the avalanche control crew to start some bombing, but the weather closed back in and they had to quit. The weather never allowed the line crew to get on the mountain, so there was no progress on the repair today.

So we still have and estimated 2 plus days of work remaining. We are hoping for better weather tomorrow, but the forecast is not promising.

1/28/09: High temperature crept above freezing for the first time since last Wednesday. Energy use on Tuesday was down 4%. Diesel use was just under 86,000 gallons, more than 3,000 gallons lower than the day before.

The weather lifted enough at Snettisham yesterday for avalanche control crews to do their control blasting, finishing about 11:30 a.m. Repair crews were then able to get on the mountain and had a short but productive day. The mid-span splices have been made to the wire and the wire is now hoisted up in the air between the two towers. This is good news because that means that the work that needed to be done in the most avalanche prone area is complete. The work that remains will be done at or near the two towers and outside the most serious avalanche zone. There are still two plus days of work remaining. A few days of decent weather is all we need.

A correction. I misunderstood the initial report from the site. The wire is up and temporarily tied off, but the splices have not been made yet. There was more snow at Snettisham last night and warming weather, so there will need to be additional avalanche control work before crews can access the repair site today. They hope they will be able to do the splicing today.


1/27/09: Monday energy and fuel use are normally higher than Sunday, but with the weather warming a bit we actually used less fuel on Monday, 89,000 gallons vs. 94,000 gallons the day before. 

Crews were not able to get on the mountain yesterday to continue repairs to the Snettisham line due to low visibility caused by the snow storm.  With the new snow that has fallen, avalanche danger at Snettisham is Considerable. Crews will not be able to continue their work until the avalanche control people do their bombing on the snow covered slopes. The avalanche control people need a break in the weather to be able to do their work. It looks like there may be a break in the weather today that could allow avalanche control activities. We still have just three more days of work to finish repairs to the line and restore Snettisham energy to town. Let's hope for the best.


1/26/09: Sunday was a bit colder than Saturday. Energy use was up slightly but diesel use was down slightly (because we got a bit more energy out of our hydro plants). With warmer weather in the forecast we should see the diesel numbers come down this week.

High winds at Snettisham continued to impede progress at the repair site on Saturady. Work had progressed to the point that the next phase of the project was to have the helicopter sling new lenghs of wire up to the site and lay it on the gound to be spliced to the existing wire. That was just not possible in the high winds. We caught a break on Sunday though. The winds died down a bit (though not as much as we would have liked) and with hard work and very skillful helicopter piloting crews got all the wire up at the repair site and laid on the ground.

The next step of the project is to splice these sections of new wire to the existing wire, then hoist it in the air and make the final connections at the towers. The snow in the forecast could be a problem if it increases the avalanche danger to the point that crews can't work where they need to, or if it hampers the visibility for crews to be able to fly to the site. There are probably three days of work remaining. Cross your fingers, carry the rabbit's foot, or whatever it is you do for luck.

1/25/09: Still cold and still using lots of fuel. Saturday we used just over 95,000 gallons, but that was still more than 3,000 than the day before.



1/24/09: Weather is colder still. Our energy consumption on Friday was 1,039 MWh, even higher than the day of the avalanche. But there is still conservation going on, it is just masked by the cold weather. To get an idea, look for a day with similar temperatures. Friday the average temperature was 17 degress. Monday, 1/5, also had an average of 17 degrees. On that day we used 1,126 MWh. Friday's use was 8% below that, so that is an estimate of the conservation that is there. Note: To keep an apples to apples comparison, I have estimated the energy that would have been used during the outages Friday morning. Keep warm, but keep conserving.

1/23/09p.m.: We just had a report from the line crew at Snettisham. It was cold and windy again today, but they got another day of work done. They are about ready to start having the helicopter sling sections of wire on the hill to splice onto the existing conductor, but need to the wind to die down before they can do much on that step. Weather permitting they will be working through the weekend on this.

1/23/09: Coldest weather since the start of the avalanche has driven energy use up again, but we are still below pre-avalanche energy use. Fuel use on Thursday was just under 84,000 gallons.

My best guess, trying to compare back to a day with similar temperatures, is that we are still seeing 10% or greater since before the avalanche.Crews were able to get on the repair site Thursday even though it was quite cold and windy all day long. They were able to change a guy wire on 3/4 (still another one yet to change) and drilled some anchors in for wire pulling. They also cleared a path to be able to pull the conductor wire.

They will have to fly several pieces of wire up on the mountain and splice them in before they raise it up on the towers. If things go well they may get the first piece of wire on the mountain today. Barring any unforeseen problems, it looks like we are still on schedule to get Snettisham back on line next week (early next week, I hope).

1/22/09: Coldest day since the avalanche, and the first day of below freezing weather. Still energy use was up only 2% from Tuesday and is down 12.5% since the avalanche began. Diesel use was 75,600 gallons. 

Low clouds prevented repair crews from reaching the mountain yesterday.
They did what organizing they could at Snettisham to make the rest of the work more efficient. The weather broke late in the afternoon and avalanche control crews were able to do some bombing work to make the site safer for crews.

The forecat for the next few days is clear, windy and cold. The clear part sounds good, but too much wind could impede the repair work. Crews are on the mountain this morning, we'll just have to wait and see how local winds are and what effect they will have on the work.

1/21/09: Cooler weather and offices and schools open after the holiday resulted in higher energy use Tuesday than Monday. Tuesday energy use was 879 megawatt-hours. Diesel use was just under 75,000 gallons. Friday was a day with similar temperatures and our energy use is still down 2% from then. 

Crews yesterday competed the modifications to tower 4/1. Today they will work on clearing a path to lay out the new wire, and clearing a landing area for the helicopter near the splice point. Crews at tower 3/4 today will continue the modifications to that tower. The goal is to turn the tower to the correct angle for the new wire. If things go well they may get that far today. The avalanche danger is increasing on site and work may be delayed a couple of hours this morning while the avalanche control people conduct another bombing run.


1/20/09: Loads up a bit from the weekend, as we expected, but still showing conservation. Energy use is still down nearly 19% from the first day of the avalanche. Some of that though is due to the much warmer weather. 

Eric tells me that at Snettisham, yesterday was spent unloading the barge with equipment and material. The good weather enabled them to fly the equipment they needed to the repair site. The carpenters erected the emergency shelters and four more linemen arrived at the site, bringing the repair crew to 8. They didn't get any actual time working on the line, but everything is in place now to hit it hard.

1/19/09: 53 degrees and a little sunshine on a weekend make a huge difference. Energy use below 800 MWhr for the first time and diesel use of 60,526 gallons. Energy use was down 22% compared to the day of the avalanche! That will come back up as the weather cools, but any daily decrease is a good thing.


1/18/09: Unseasonably warm temperatures, and a weekend vs. a weekday produced another big decrease in diesel use. Energy was down Saturday another nearly 5% from the day before, and diesel was under 73,000 gallons that day.  I expect there will be an additional improvement Sunday with sunshine and high temperature.

Scott also provided the below photos and repair status comments from Eric Erickson who is on site at Snettisham:

"With the good weather this weekend, crews made pretty good progress on the repair. They have tied off the conductor at both towers 3/4 and 4/1, and cut it free from the conductor on the ground. This is significant because while it was still connected, if another avalanche came down and caught tower 3/5, it could have pulled so hard on the conductor that it could have damaged or destroyed the adjacent towers (just as it did last spring). Should be no danger of that now.


The barge with equipment and shelters made it to Snettisham on Sunday. Additional linemen are due to arrive at Snettisham on Monday, so if we have good weather we should be extremely productive."

1/17/09: Temperatures very nearly the same as the day before, but energy use on Friday was down another 2.2% from Thursday. This is the first day below 900 megawatt-hours, and the first day below 80,000 gallons of diesel. Energy use is down 12.4% since Monday (1/12).


1/16/09: A little warmer yesterday (1/15), and energy use up slightly...I've added a couple more columns to show the percent change since the day before and the total % change since January 12, the day of the avalanche.


1/15/09: Energy use yesterday was down 3.7% from the day before (949 to 914). Diesel use down 3.9% over the same period.


1/14/09: First full day on diesel. We used just over 80,000 gallons. Average temperature was the same Tuesday as it was Monday, but total energy use was already down 7% (949/1025).
