Alabama Power Company, headquartered in Birmingham, Alabama, is a company in the southern United States that provides electricity service to 1.4 million customers in the southern two-thirds of Alabama. It also operates appliance stores. It is one of four U.S. utilities operated by the Southern Company, one of the nation’s largest generators of electricity.Alabama Power is an investor-owned, tax-paying utility, and the second largest subsidiary of Southern Company. More than 78,000 miles of power lines carry electricity to customers throughout 44,500 square miles .Alabama Power’s hydroelectric generating plants encompass several lakes on the Tallapoosa, Coosa, and Black Warrior rivers, as well as coal, oil, natural gas, nuclear and cogeneration plants in various parts of the state. In addition to generating electricity, the waters surrounding the plants offer recreational opportunities for Alabama residents and visitors. Wikipedia.

Strategic Planning for Energy and the Environment | Year: 2011
Given the strong concern for the environment, a national desire to be energy independent, and a need to reduce corporate expenses, the stage is set for corporate energy management initiatives to be more successful than ever. Implementing a corporate energy plan can be challenging, and a number of important factors will primarily determine the effectiveness of these initiatives. This article presents recommendations for developing a successful energy management program from the perspective of an electric utility representative.

Restoring service to customers has always been a top priority at the Alabama Power Company during my 45 years there. Although the task is the same, the methods and technologies that can be brought to bear on it have changed and improved dramatically. Technology has helped the company improve its response to system disturbances. Automation technology deployed in the distribution control room, in distribution substations, and at discrete sites along the distribution feeder provides system intelligence regarding the state and condition of the electric distribution system. Automation technology also facilitates the presentation of supervisory control and data acquisition (SCADA) telemetry to the distribution operator. Meanwhile, advances in desktop computing workstations permit the geographical display of distribution circuits in a wide-area view, which improves the visibility of the distribution system for the operator. The big-picture or wide-area view that was once displayed on the paper map board is now presented in the control room on its desktop workstations. Today, application integration is providing the next round of technology improvement in the distribution control room. Advanced applications within an integrated platform are providing techniques to improve the efficiency and reliability of the distribution system. Together, these advanced applications improve service restoration. This article describes the past, present, and future of service restoration technology at Alabama Power. © 2003-2012 IEEE.

Medium-voltage (MV) sensors for the Smart Grid are an evolving tool for the electric utility distribution engineer. Historically, to remotely monitor the power system flow on a distribution system, the most common option available was traditional current transformers (CTs) and potential transformers (PTs) combined with transducers. The most common means of communication was a leased telephone circuit. Around 1990, as the visions of fully automated distribution systems began to surface, a need was recognized for a device that could detect the magnitudes of the distribution system's primary voltages and line currents - devices that would be less expensive and less cumbersome to install and operate than the traditional CT and PT. Thus was born the MV sensor. As with many other emerging technologies, the evolution of these MV sensors - from the concept of a cycloalaphatic or epoxy post-type insulator with embedded discrete components to the more recent concept of a polymer with optics - has been filled with trials and tribulations. This paper covers some of the basic design concepts, technical capabilities, applications, reports of independent lab tests, and "lessons learned" with these sensor types, which are destined to become part of the initial building blocks for the Smart Grid. © 2011 IEEE.

Large disturbing loads such as electric arc furnaces (EAF) create fluctuations in source voltage at the point of common coupling (PCC). These voltage fluctuations then propagate throughout the power system with varying degrees of attenuation. The amount of attenuation is, in general, a function of system impedance and load composition, and can be characterized by what is known as a flicker transfer coefficient. The frequency response of synchronous generators near 60 Hz has a significant effect on flicker propagation, particularly in networked HV or EHV systems. To date, information available in the literature has not adequately described this phenomenon from a theoretical perspective or shown how to take this affect into consideration when computing flicker transfer coefficients. The following paper addresses these issues by: 1) providing a formal description of a synchronous generator model that can be used to determine flicker transfer coefficients when traditional modeling methods may not be appropriate and 2) providing a novel way of calculating flicker transfer coefficients using the described machine model. Synchronized flicker measurements, made at an EAF installation and nearby generating facility in the Southern Company service area, were used to validate the results of the proposed method. © 2009 IEEE.

Conventional power plant performance metrics are designed for dispatchable generation. These can be difficult to apply to variable generators such as wind and solar power. This article describes additional metrics that can be applied to photovoltaic (PV ) power plants and illustrates these metrics using measured data collected from a 1-MW PV plant in Tennessee over a one-year period. The article persuades that new metrics will be needed to measure and effectively employ PV for duty in a traditional generation fleet. © 2003-2012 IEEE.
