4. System Average Interruption Frequency Index (SAIFI) in CY 2012–CY 2016

The System Average Interruption Frequency Index (SAIFI) is the average frequency of sustained interruptions per customer served in a predefined area (lower number means better SAIFI performance).

Pepco’s SAIFI decreased each year from 2012 through 2015. In 2016, Pepco’s performance in the District was slightly higher than the previous year (0.69 compared to 0.82) and was better than the DCPSC standard since 2013.

In 2016, Pepco's SAIFI of 0.82 was lower than DCPSC Reliability Performance Standard (EQSS SAIFI) of 1.02 and lower than FC. No. 1119 Merger Commitment SAIFI of 0.91.

5. System Average Interruption Duration Index (SAIDI) in CY 2012–CY 2016

The System Average Interruption Duration Index (SAIDI) is the average length of time that the customers served in a predefined area are interrupted. In other words, SAIDI measures the average duration of system outages (lower number means better SAIDI performance).

Since 2012, SAIDI has been better oreq than the DCPSC standard.

In 2016 there was an increase in SAIFI from 1.87 (2015) to 1.92 (2016). However, the 2016 performance is still better than the DCPSC Standard of 2.00 and the Merger Committment SAIFI standard of 1.97

6. Customer Average Interruption Duration Index (CAIDI) in CY 2012–CY 2016

The Customer Average Interruption Duration Index (CAIDI) is the average time required to restore service to the customers experiencing a sustained interruption. In other words, it measures the average duration of outages per customer (lower number means better CAIDI performance).

In 2013, Pepco’s CAIDI decreased from 3.12 to 2.35, matching the industry average. In 2014, Pepco’s CAIDI decreased to 2.34, slightly below the industry average for the previous year. In 2015 there was an increase in CAIDI to 2.73. In 2016 there was a decrease in CAIDI to 2.35.

7. Average Residential Electric Bills in D.C., MD, & VA* in CY 2012–CY 2015

In D.C., Pepco’s average residential electric bill includes generation, transmission and distribution and all additional charges, including federal and D.C. taxes and surcharges. In 2016, the average monthly consumption for residential customers (both winter and summer seasons) was 604 kWh.

In CY 2016, average residential electric bills continued to be lower in D.C. than in Pepco’s MD service territory. The average bills in D.C. were slightly higher than in Northern VA, where electric service is provided by Dominion Power.  

The distribution charge (including fees, taxes and surcharges) represents about 34% of the electricity bill. The other 66% of the average residential bill is made up of the cost for electricity itself (which is sold by licensed retailers whose rates are not regulated by the Commission or by Pepco in its role as the default provider of Standard Offer Service, or SOS) plus transmission.

*Average monthly usage varied between 504 kWh in winter and 742 kWh in summer. Virginia statistics refer to Dominion Power in Northern Virginia.

8. Enrollment in Pepco's Low Income Residential Aid Discount (RAD) Program* in CY 2012–CY 2016

The number of participants enrolled in Pepco’s Low Income Residential Aid Discount (RAD) program dropped by 4.3% between CY 2013 and CY 2014. In CY 2015, enrollment increased by 3.3% from 2014 levels. In CY 2016, the trend of the increase in enrollment continued at 1.4% from 2015 levels.

The DCPSC, in Order No. 17545, dated July 14, 2014, opened Formal Case No. 1120 to investigate the structure and application of low-income assistance for electricity customers and to design a discount program for low-income electricity customers that will work within the District’s current restructured market.

The Commission convened a Technical Conference on July 23, 2014 and five additional meetings ending on March 19, 2015. On December 15, 2015, the Commission, in Order No. 18059, adopted a new methodology for computing the Residential Aid Credit (RAC) for eligible low-income electricity customers. The methodology for computing that Residential Aid Discount was changed to reflect a Residential Aid Credit equal to the full distribution charge each month, thereby allowing portability of the discount.

9. Total Number of Manhole Events (Explosions, Fires and Smoking Manholes) in CY 2012–CY 2016

Reportable manhole events for CY 2016 decreased by 16 events when compared to CY 2015. Reportable events may be considered a subset of underground (UG) equipment failures, and are comprised of equipment failures for which there is a significant visual result (smoke, flames, cover displaced). Among UG equipment failures, the most frequent involve cable.  

Of these 67 manhole events, 50 were classified as Smoking Manholes, seven were classified as Manhole Explosions, and 10 were classified as Manhole Fires.

10. Explosions as a Percentage of Total Manhole Events in CY 2012–CY 2016

From CY 2012 through CY 2016, most of the reportable events were manhole smoking events. Explosions as a share of manhole incidents decreased from 34% in 2012 to 17% in CY 2014 to 12% in CY 2015 and continued to decline to 10% in CY 2016.

11. Number of Explosions for Slotted vs. Solid Manhole Covers in CY 2012–CY 2016

Slotted manhole covers are designed to minimize the frequency and impact of manhole events by allowing gas and smoke to vent from manholes in the event of an underground failure. Slotted manhole covers allow energy to disperse more easily when an event occurs, thereby preventing buildup of gases to potentially explosive proportions. The trade-off when installing slotted covers is that they allow more water and street run-off contaminants to enter the manhole than solid covers.

In CY 2016 there were seven explosions in solid manholes and none in slotted manholes.

12. Pepco's Public Space Occupancy Surcharge (Rider PSOS) in CY 2012–CY 2016

Pepco’s Rights-of-Way (ROW) Fee is called a Public Space Occupancy Surcharge Rider (Rider PSOS) and it appears as a separate surcharge on Pepco’s customers' bills. Pepco files proposed PSOS updates once a year in docket ET00-2. The surcharge update consists of two parts reflecting: 1) the payments to be made by Pepco to the District of Columbia for the current year, and 2) the over or under recovery from the prior year. The DCPSC audits the PSOS to verify the costs the Company pays the District to lease space in underground conduits.

The PSOS rate per kilowatt-hour began to increase in CY 2013 and CY2014 due to prior years' under recovery. The CY 2016 Rate increased from $0.00204 in CY 2015 to $0.00209 in CY 2016.

13. Number of Renewable Portfolio Standard (RPS) Applications Received by the DCPSC in CY 2012–CY 2015

The impact of the Distributed Generation Emergency Amendment Act of 2011, which generally disallowed out-of-state solar energy systems explains the decrease in the number Renewable Portfolio Standard (RPS) Applications in 2012.

However, that trend has now reversed. In CY 2012, the Commission received only 257 solar facility RPS applications, but in each subsequent year the number of applications increased. In CY 2015 there was a 52% increase in the applications compared to CY 2014. In CY 2016 there was a 14% increase over CY 2015 to the high of 818.
