Storm recovery data acquisition
Results
After two days were spent simulating a Storm Recovery patrol, walking and a driving collection metric are
displayed below. Each collection covers the entire distance between two switches.

The next table is from the walking collection and is an example of what would be imported into the existing
SRR Lotus Notes application. This data would be available for import within 30 minutes of the field
computer returning to the office. The software would be configured to import this data automatically once
the field unit is connected to the network.

The pilot of the speech-to-data method demonstrated the feasibility speech enabled data collection for
Storm Recovery.
Summary
Storm Recovery can be transformed to a much more efficient process as shown by the results verified in the
pilot:
| Paper Storm Recovery |
VoCarta Storm Recovery |
| 1. SRR forms are difficult to learn |
Prompts & teaches the form as you go. |
| 2. SRR forms are difficult to use |
No writing required. Just see it and say it. |
| 3. Difficult to locate the correct section. |
GPS highlights the section next to you. |
| 4. Not familiar with area, no signs, lost. |
Never lost, always see where you are on map. |
| 5. Rain and wind interfere with collection. |
No wet papers to deal with. |
| 6. The second man in the truck can't keep up. |
You can call data out 3-5x faster to VoCarta. |
| 7. Dozens of people entering data all night. |
This step and its inaccuracies are eliminated. |
| 8. No discreet locations of specific damages. |
Damaged equipment shown on map and tallied. |
These efficiencies have the following economic value for FPL:
-
Accurate SRR information in 36 hours instead of 5 days allows SRR to be utilized as a crew
forecasting tool which can save FPL $50,000,000 in crew and equipment over-reaction costs.
- With the GPS locations of specific damages SRR data can be used by GIS to generate best routing for
repair crews to expedite truck loading, arrival at feeders and order of repairs along the feeder. Better
preparation and routing improves productivity by 15-30% in most cases.
- A 15% productivity improvement shaves 5 days off 33 days of repair. A 10% damage area hurricane
disrupts FPL's $18,000,000 daily cash flow by $1,800,000 per day. Five days represent $9,000,000 in
cash flow.
Conclusion
FPL has the opportunity to utilize new technology to change the rules and the paradigm it was previously
constrained by. The new capabilities made possible by this technology allow FPL to make leaps forward in
its four areas of focus:
- Cost
VoCarta reduces daily costs by improving field inspection crew productivity today while improving
FPL's asset maps to dramatically reduce future maintenance response times.
Economical streetlight location and verification reduce collection costs by $450,000 while accelerated
collection of unbilled revenue produces an extra $7,500,000 in the next two years
Storm recovery costs may be reduced by $50,000,000 based on greater speed and more
accurate/mapped data from SRR providing better damage estimates earlier with better response routing
of repair crews.
Better deployment and routing of repair crews after a category 4 hurricane could reduce repair time by
a week, reducing repair costs while reestablishing cash flow sooner. A one week improvement could
save FPL $10,000,000 in repair and $9,000,000 in cash flow.
- Quality
Better location and accounting of assets in the field allow FPL to better respond to its own growth
needs as well as its emergency outage needs.
- Customer Orientation
Better response times and maintenance improve customer satisfaction with FPL's ability to deliver
services that satisfy their electricity-related needs.
- Speed & Flexibility
With accurate GPS location of vault access, pads, poles, transformers and lights FPL crews can locate
and deploy maintenance crews faster. With accurate maps of damaged assets included with SRR
information provided days earlier FPL has the flexibility to tailor its response rather than gross overestimation
which is the only alternative without good timely field data to ground-truth estimates.
