Re: Pepco Update Regarding Corrective Actions and Reliability Improvements
Good
Afternoon,
We
want to share that we have rescheduled the 30 minute outages required for the
transformer inspections. The work is now scheduled to occur overnight Thursday
and Friday night of this week. Below is information that we shared regarding
the inspections.
In
order to inspect the transformers which serve the majority of the Bloomingdale
community, we will need to de-energize customers for approximately 30 minutes.
The transformer inspections will also begin on the evening of Thursday,
November 21st and will continue on the evening of Friday, November 22nd. These
scheduled outages will last for approximately 30 minutes and will occur between
the hours of midnight until 6 a.m. The customers impacted by the transformer inspection
will also receive a door hanger notifying them of the 30 minute outage.
It
is important to note that the 30 minute outages will not occur at the same time
for all customers on these feeders. The 30 minute outage will occur only on the
particular transformer being inspected. Once the inspection is complete,
service will be restored on that transformer and we will begin this same
inspection process on the next transformer. Unfortunately, we cannot pinpoint
each customers specific outage time during the midnight to 6 a.m time frame as
we will be inspecting several dozen transformers as a part of the inspection
process. However, we will approximate
that the outages for the commercial customers, particularly the restaurants and
bars located within the community, to occur between 4 a.m. and 6 a.m.
Again,
the customers impacted by the transformer inspection will receive a door hanger
notifying them of the 30 minute outage that will occur between the hours of
midnight and 6 a.m. on the evenings of November 21st and 22nd.
If
you have any questions or concerns, please let us know and we will be glad to
follow up.

Good
Evening,
I
hope everyone had a great weekend!
We
wanted to provide a quick update regarding two of the projects scheduled to
start this week.
1.
Transformer Replacement - 1st and Adams St., NW
We
have decided to reschedule the transformer replacement at 1st and Adams St. NW.
With temperatures dropping into the 20's tomorrow night, we opted to postpone
the 8 hour outage until warmer weather next week. This project was originally
scheduled to occur tomorrow evening from 11 p.m. until 7 a.m. The outage is now
scheduled to begin on Tuesday evening, November 19th at 11 p.m. and will
conclude Wednesday morning, November 20th at 7 a.m. Customers impacted by this
work were notified of the schedule change today by a door hanger notification.

Re: Pepco Update Regarding Corrective Actions and Reliability Improvements
Good
Evening,
We
wanted to provide a quick update on our activities. As we previously
communicated, we continue to utilize advanced technologies to identify
additional areas where equipment upgrades may be necessary. The transformer
replacement at 1st and Adams St., NW has been scheduled for the evening of
November 11th. We will need to de-energize customers to complete the
transformer replacement. We anticipate the outage last from 11 p.m. on Tuesday
until 7 a.m. Wednesday. Customers impacted by this work will be notified
directly with a door hanger and will also receive an automated call.
We
have also expanded our project to include an inspection of the fuses on the
identified transformers. Beginning on the evening of Monday, November 11th and
continuing over the course of three nights, crews will begin the transformer
inspections. To accomplish this analysis, crews will need to de-energize
customers for approximately 30 minutes. We previously communicated that these
outages would last approximately 15 minutes. We still anticipate the outages to
last 15 minutes; however, in the event that the inspection takes longer than
expected, have extended the outage duration to provide for the additional
inspection time.
The
transformer inspections will occur at locations throughout Bloomingdale.
However, each customer should only be impacted by the outage one time.
Customers impacted by the inspections will be notified by door hanger of the
date of their 30 minute outage. Please note that crews began distributing the
door hangers concerning this work on November 5. Unfortunately, a mistake was
made and the door hangers indicated that the outage would last from 10 p.m.
until 6 a.m. These door hangers have been removed and will be replaced with
with the correct information: a 30 minute outage between 10 p.m. and 6 a.m. If
you have any questions about this, please let me know and I will be glad to
follow up.
Finally,
we also wanted to share that we have completed the cable replacements at 4th
and R St. ,NW and have completed the transformer replacement at Flagler and V
St., NW. We have also started the conduit repairs on Feeder 147; the conduit
work on Feeder 14200; started the cable injections on Feeder 14004 and 14001;
and started the infrastructure relocation project related to DC Water's
Northeast Boundary Tunneling project.
If
you have any questions, please let us know.

Pepco Update Regarding Corrective Actions and Reliability Improvements
Good
Afternoon,
We
wanted to provide further details regarding the cause of the outages that
occurred on Tuesday October 15th, and the related corrective actions.
Additionally, we also wanted to provide information regarding the reliability
enhancement projects in Bloomingdale.
Recent
Outages and Corrective Action
The
outages on October 15th occurred on two separate feeders, Feeder 147 and Feeder
14004. For informational purposes, a feeder is a set of cables that supply
power to customers in a specific geographic area.
The
cause of the outage for Feeder 147 was a blown joint, which is where two
sections of cable are connected (spliced) together. Pepco plans to replace
Feeder 147 with cables that have additional capacity. As such, we will convert
the exiting cables from 4 kV to 13 kV. In order to install these new cables,
Pepco must first repair 4 conduit pipes at 4th and Elm St., NW; on 2nd between
Elm and V St., NW; and on V St. between 4th and 5th St., NW. Pepco plans to
start these repairs today, with conduit repairs taking approximately 3 weeks to
complete.
Once
the conduit work is complete, we will install the new 13 kV cable. This portion
of work should take approximately 2 weeks and will start immediately after the
conduit work is conducted. The new cable installations will occur in the
following locations:
V
St. from 2nd St. to Flagler St., NW
Bryant
St. from Georgia Ave. to 2nd St., NW
4th
St. from Bryant St. to McMillan Dr., NW
4th
St. from V St. to U St., NW
Elm
St. from 4th St. to 2nd St., NW
2nd
St. from U St. to V St., NW
Oak
Dale Pl. from 5th St. to 4th St., NW
The
second outage that occurred on Tuesday was on Feeder 14004. This outage was
caused by a failed transformer, which was immediately replaced. In order to
strengthen the reliability of this feeder, crews will also conduct cable
injections, which will enhance insulation of the cable. We also plan to conduct
thermal testing on this feeder in order to identify locations of potential
equipment issues. If this testing reveals "hot spots," crews will
take corrective action by either replacing the cables or the transformers. We
plan to start the thermal testing and cable injections next week.
Additional
Projects
In
addition, we continue to utilize advanced technologies to identify additional
areas where equipment upgrades may be necessary. To date, this analysis has
identified the need to complete the following projects:
Replace
secondary cables at 1st St. and Seaton St., NW (Feeder 14004) Completed on
10/21/13
Replace
secondary cables at 4th St. and R St, NW (Feeder 15204)
Upgrade
a transformer at 1st St. and Rhode Island Ave., NW (Feeder 15462)
Upgrade
two transformers at 1st St. and Adams St., NW (Feeder 14200)
Install
one new transformer at Flagler Pl. and V St., NW (Feeder 15462)
Cable
Injections and thermal testing (Feeder 14001)
Our
analysis revealed an immediate need to replace some of the cables at 4th and R
St., NW. Therefore, crews made these repairs on, October 23rd. Crews will
complete additional cable replacements in this area on November 1st. To
complete these replacements, a scheduled outage will be required on November
1st, from 10 a.m. until 3 p.m. Impacted customers will be notified by door
hangers. Cables will be replaced on the following blocks:
400
block of R St., NW
300
block of R St., NW
200
block of R St., NW
1600
block 4th St., NW
1700
block 3rd St., NW
The
other transformer and cable replacements listed above have not been scheduled;
however, crews are targeting this work for the weeks of November 11th and
November 18th. Customers will be notified of this work by door hangers and by
automated phone calls.
Also,
please note that we have scheduled a project to replace additional cables on Feeder
14200, commencing on October 28th. This information was communicated to the
Councilmember, impacted Advisory Neighborhood Commissions and customers last
week. As a reminder, this project will increase the capacity of cables, add a
new transformer and increase the capacity of another transformer. It will take
place in the alley between N. Capitol St., 1st St., W. St, and Adams St., NW.
Finally,
as part of ongoing additional analysis, crews will also inspect the fuses on
each transformer of Feeders 14001 and 14004. To accomplish this analysis, crews
will need to de-energize customers for approximately 15 minutes. This work has
not been scheduled; however, crews are targeting this work for the weeks of
November 11th and November 18th. Customers will be notified by door hangers and
by automated phone calls. The outages will be scheduled overnight to minimize
impact to customers.
Northeast
Boundary Tunneling Project
In
support of DC Water's Northeast Boundary Tunneling project, we advanced a
project to accommodate the electric service for the tunnel machinery. This work
involved installing a new transformer at the Florida Avenue Substation and a
new 69 kilovolt (kV) transmission line.
In addition, in May crews began constructing 6 new 13 kV feeders between
the Florida Avenue Substation and Children's Hospital. Crews are currently
completing the final portion of the conduit work on Michigan Ave. and will
install the cable once the conduit work is complete. You can expect to see our
activity to increase along 1st St., NW within the next two weeks. Crews will
first have to relocate existing infrastructure, then install a temporary
overhead supply line for the tunneling machinery. The infrastructure relocation
will start within 2 weeks. Crews will be working in the following locations:
Infrastructure
Relocation
First
St. and Thomas St., NW: Excavate approximately 187 feet mostly in the sidewalk
First
St. and V St., NW: Excavation centered at the intersection for infrastructure
relocations
2225
Flagler Pl., NW: Minor excavation for equipment relocation
Temporary
Overhead Service
First
St. from Michigan Ave. to Channing St., NW: Extend temporary over head high
voltage service to supply tunneling machinery
First
St. and Michigan Ave., NW: Conduit work to transition from underground to
overhead
Thank
you for the opportunity to provide additional details concerning the outages
last week and our reliability improvements for the Bloomingdale Community. We
have attached the Fact Sheet that was generated at the beginning of September.
It contains information about recently completed reliability improvements. This
document will continue to be updated as projects progress.
We
would be glad to present this information to a future ANC or Civic Association
meeting.
