COLUMBUS, Ohio, May 8, 2014 /PRNewswire/ -- American Electric Power (NYSE: AEP) has released its 2014 Corporate Accountability Report, an overview of its strategy and business performance. The web-based report, available at www.AEPSustainability.com, is complemented by an interactive app that will be available on iTunes in the near future. This is AEP's eighth year of reporting on its sustainability performance and its fifth integrated report combining sustainability and financial information. The company's reporting is guided by the Global Reporting Initiative, the International Integrated Reporting Council and the Sustainability Accounting Standards Board. "Our 2014 Corporate Accountability Report recognizes the relationship between our financial performance, employee health and engagement, and our environmental responsibilities," said Nicholas K. Akins, AEP's chairman, president and chief executive officer. "Updating stakeholders on our efforts demonstrates our dedication to being transparent and recognizing the social impact of our activities." AEP's 2014 Corporate Accountability Report is focused on several key areas: business performance, technology and innovation, customers and communities, and AEP's workforce. Among its highlights, the report discusses AEP's 2013 financial performance. AEP earned $3.23 per share in 2013, above the mid-point of the company's earnings guidance range. AEP's total shareholder return for the year was 14.2 percent, compared with an average of 7.8 percent for the S&P 500 Electric Utilities Index. The report includes notable workforce-related successes. In 2013, employees implemented sustainable process improvements and began a journey to reshape AEP's culture to be as collaborative and customer-focused as possible. Employees also completed a second year in a row with no fatalities. The report also discusses AEP's 2013 environmental performance, which was the best in company history. AEP has invested about $10 billion in environmental controls and new generation over the past decade. Between 2005 and 2013, AEP reduced its carbon dioxide emissions by 21 percent. The company also reduced sulfur dioxide and nitrogen oxide emissions by more than 80 percent each since 1990, and reduced mercury emissions by nearly 60 percent since 2001. The report highlights AEP's increasingly diverse generation fleet as the company retires nearly 6,600 megawatts of coal-fueled generating capacity between now and 2016 due to environmental regulations and market conditions. AEP's generating capacity is expected to shift from 61 percent coal and 23 percent natural gas in 2014 to 49 percent coal and 28 percent natural gas in 2026. The company's use of renewables and energy efficiency resources will continue to increase during that period.
