Code § 53.52(a)(1) INTRODUCTION Duquesne Light Company (“Duquesne Light” or the “Company”) is responsible for providing adequate, efficient, safe and reliable electric service to its customers and must have the ability to raise capital to meet such requirements. The Company is allowed to charge just and reasonable rates as established by the Pennsylvania Public Utility Commission (“Commission”) that provide the Company with a fair opportunity to recover its operating costs and earn a fair return on its investment. This is accomplished through a rate case process. In this filing, Duquesne Light is requesting that the Commission approve an overall annual increase in distribution revenue of approximately $76.3 million. If granted by the Commission as filed, this request would produce a system average increase in distribution rates of approximately 17.6% and an increase in total rates (distribution, transmission and generation charges) of approximately 10.6% for a typical residential default service customer. The percentage increase in rates differs for each individual rate class. DUQUESNE LIGHT COMPANY’S COSTS Duquesne Light has controlled its operation and maintenance expenses by implementing process improvements and deploying cost saving measures. Nevertheless, the cost of providing electric distribution service has increased since the last distribution rate increase in April 2011. Significant cost increases have occurred in many areas, including increased investment in facilities to maintain high levels of service and reliability, increased investment in information technology, increased operation and maintenance expenses to maintain safe and reliable service, including increased vegetation management expenses, and increased costs for Company’s cyber security initiatives to maintain the integrity of the Company’s and customers’ information. In addition, the Company’s net plant will have increased by approximately $266 million as of the end of the future test year in the 2010 base rate case through April 30, 2015. DUQUESNE LIGHT’S FINANCIAL CONDITION Absent increases in rates, Duquesne Light’s financial condition would continue to decline in the fully projected future test year due to continued capital expenditures and increased operating expenses. On a pro forma basis for the fully projected future test year, Duquesne Light anticipates an overall return on rate base of only 5.67% absent rate relief. These financial results do not provide a return that will permit the Company to attract Schedule A Page 2 of 2 new capital on reasonable terms. Revenues at present rates do not provide the Company the opportunity to earn a fair return and simply do not provide sufficient funds for Duquesne Light to adequately operate its business, abide by federal and state requirements, and provide reliable electric service to its customers. RELIABLE ELECTRIC SERVICE Duquesne Light has consistently provided its customers with service at reliability levels as measured by SAIDI and SAIFI that are at or near the top of the levels provided by all of the major Pennsylvania electric distribution companies. Duquesne Light has increased efficiency and reliability through the use of technology, such as automated meter reading systems and automated control systems that continuously monitor remote switches that can be operated to re-route power during storms and other outages to quickly restore service to large blocks of customers. The Company also has adopted or is adopting additional measures to maintain and improve its reliability, including enhancements to its vegetation management program, establishing a service restoration team to identify ways to improve service restoration times, and developing programs for improving low performing electric circuits. CUSTOMER SERVICE Duquesne Light has consistently provided high levels of customer service. The Company is currently subject to customer service metrics as a result of the transfer of certain interests in DQE Holdings LLC to Epsom Investment Pte Ltd. The Company has exceeded these customer service metrics.
