ALSTOM GRIDSMART DISTRIBUTION SOLUTIONS FOR SMART UTILITIES As electric distribution utilities face intense Smart Distribution pressure to find new and innovative ways to reduce their costs, Smart Distribution As the Electric Distribution industry enters the Smart Grid era, it is deploying a variety of new offers promising solutions for enhancing technologies (including distributed energy resources) grid performance and increasing customer and communications infrastructure to enhance satisfaction, while creating a more sus- the performance of the distribution grid, improve tainable environment. customer satisfaction and reduce the carbon foot- print. On the one hand, these new Smart Grid investments look as though they will pay off as cus- tomers begin to enthusiastically adopt photovoltaic solar systems, electric vehicles, demand response, etc. On the other hand, the challenging economic climate finds electric distribution utilities still fight- ing an uphill battle with state regulatory entities in order to justify the expense of their investments. These opposite forces will pose unique opportuni- ties and challenges to electric distribution utilities. Smart Grid solutions call for enhanced operational methodologies as well as better economic models to reliably and profitably manage future distribution grids. To begin engaging in solutions that proactively meet these new challenges, the Electric Distribution industry has introduced the term Smart Distribution.

Not only does this aid in reducing fuel costs and carbon monoxide emissions from crew trucks, Smart Metering also cuts customer outage times by up to 30%, thus improving reliability indices (such as SAIDI, CAIDI) and improving customer satisfaction and furthering relations with industry regulators.
