repetitive candidates for futher inquery as street lights:
outliers for further inquery:
141 had 350, 7 times avg. 144 flat 0 energy 151-154 had issues, 2 0 energy usage, 2 had 350+ 202 had 250, 5 times avg. 223 at 0 energy use
Average energy use seems to fall in the shape of a double bell curve with two maximum usage groups centered around 70 and 35

^ We were trying to import Python script in order to find the means of a couple of data points, but it did not work. ^
Total amount of time that data was offline: 2,730 data points,Total time of recorded date: 32,616 data points, Percent of total time that data was offline: 8.37%,The system is at least 91.63% reliable as far as we know
finding total appliances/lighting: 5 applications at one time
4 applications at one time
5 appliances at one time
4 appliances at one time
They use three 1 watt appliances; most probably a mixture of 1 watt clock, led lightbulbs and phone charger. aside from that they use a single 3 watt appliance. This could likely be two things; either a clock or a double A battery charger which is exactly 3 watts to run.
maximum of 6 appliances, three to four 1 watt appliances, a 2 watt appliance and rarely a 6 watt appliance
This is one of the most energy using families-at times consuming 30 watts+, this is one of the families that could have a television. From the energy usage data it seems that less than 20% of households own a tv.
We have been looking at the data in lots of different ways, cumulative kwh yearly usage as well as looking at daily houshold power usage and comparing high and low usage household appliances. We found that the average monthly usage without the upper and lower outliers comes to around 3.0 kwh. We also found the minumim offline time of the overall grid and found that the grid is online at least 91.63% of the time. This is counting all missing data points as offline so the real online time of the grid is definitely above 91%, although is still does not compare to the US reliance of above 99% for our grid systems. The reliance could be closer to 99% but the data was not recorded. When looking at individual households we found that most houses use two to four 1 watt led light bulbs along with phone chargers, clocks, and radios. A smaller portion of the households, around 15% use higher amounts of power at once which leads us to believe that they own televisions which run on 25-30 watts. Most households power spikes occur in the evenings, with noticable light bulbs being turned on for 4-6 hour periods.
#5.5 earthquake very close to Lake Sentani, 18th of september 2016
This 5.5 magnitude earthquake took place on the eighteenth of September, 18, 2016 07:17 UTC very near the city of Jayapura.
There was also this 5.9 magnitude earthquake september 17th 2016 also near Jayapura
small minute long outages, possibly eq relateed but very very minimal
The largest major outage runs from september 12th until september 14th, but one third of house holds seem to keep power, which makes us think it may be a collection malfunction.
File "<ipython-input-34-fe39fd2f8005>", line 1
Major earthquake we had to find actual timestamp as different weather data was in greenich mean time vs. our local time. none the less the grid was resiliant during the 18th and 19th during the powerful earthquake.

SyntaxError: invalid syntax
We found that there was 0 sunlight for octobor 18th 2016 which corrosponds to the outages on the 19
large outage chuncks two thirds into octobor; looking for weather related causes
Avergae of 45 eq's per yr in Lake Sentani area over 4.5 magnitude'
True average of mean for overall daily avg power usage per household below
0.166157 kwh avg per day per household. = 166 watts a day. (not including smallest outliers under 1kwh)
