How can utilities leverage disruptive digital technologies to their advantage and which no-regret actions can they take as part of their transformation journey?
Jack Azagury, Managing Director, North America Utilities, Accenture
3:00 – 4:30pm Setting the Policy – Electrifying Tomorrow Regulators – Responding or Driving Change?
Long a leader in innovative regulatory policies, Illinois has a history of successful collaborative efforts to come to grips with evolving regulatory issues, including restructuring of the electric industry in 1996-97. It also has led on evaluating smart grid deployment in 2009-2010. These new dynamics of electricity supply, demand, and storage hold great promise for consumer and social benefit, all facilitated by the smart grid that is on the way toward full deployment in Illinois. They also present significant challenges to utilities who must integrate distributed energy resources seamlessly while maintaining efficient, safe, reliable and affordable service that meets the needs of all customers. The transformed energy landscape also poses new challenges for customers, who must understand an expanding array of new options to make good choices, for suppliers of services who seek to enter new markets, and for regulators, who must ensure that all customers are treated fairly and that utilities maintain financial viability in the new environment.
Chairman Brien Sheahan, Illinois Commerce Commission
Updating the Utility Framework
What new regulations and policies are needed to allow utilities to fully embrace what technology has to offer and transform the utility relationships and offering with customers? How does a utility prepare internally to address a whole new world of regulatory and policy challenges? With a very proactive local government with its own vision of the future of energy—what challenges and opportunities is that creating for a utility and the consumers its serves? What is at stake for the utility and its customers—if the utility regulatory framework is skewed or incomplete?
Fidel Marquez Jr., Senior Vice President, Legislative & External Affairs, Chief Governmental & Community Relations Officer, ComEd
Transitioning to the Cloud, What Policymakers Need to Know
As the grid adopts new technologies to achieve greater resilience, they will increasingly move to the cloud—and have an ocean of data to effectively mine. What new capabilities are on the horizon—and what policies and regulation must change to allow the grid of tomorrow to flower? What do regulators need to understand about the new information tools that are proliferating? Do utilities need greater regulatory freedom to fully implement the gains of the cloud—to benefit both their own internal operations as well as offer customers a raft of new services? What business models should utilities embrace? And how efficiently are utilities deploying new information technology compared to other sectors of our economy?
Mark Hura, Global Vice President, Oracle Utilities
Driving Energy System Integration
The existing U.S. power system has served us well, but our 21st century economy needs a 21st century grid. The future building of the grid must deliver reliable, affordable and clean electricity to consumers where they want it and how they want it. Because energy systems are comprised of many interacting, interrelated, and interdependent sub-systems that extract, convert, deliver, and use energy at different scales, this strategy is being addressed through a systems approach across the entire energy infrastructure. A focus on how these energy components, sub-systems, and systems interact is key to widespread adoption of clean energy technologies that meet our nation’s energy goals. What do you need to know about new approaches to energy integration now being tested at federal labs? How can you bring your utility and company to the table to help pioneer changes on this front?
Dr. Martha Symco-Davies, Director of Partnerships for Energy Systems Integration, National Renewable Energy Laboratory

What does the industry and public need to know about federal energy policies?
Commissioner Colette D. Honorable, Federal Energy Regulatory Commission
Aiming Past the 2016 Presidential Sweepstakes
Electricity sales in the United States are not collapsing, but since 2000 the rate of growth has lagged well behind that of the population. Linking utilities’ financial health to escalating commodity sales won’t work any longer. This yields two crucial questions: given declining growth in those commodity sales, how do utilities secure the reasonable revenue certainty required to make enduring provision for reliable and affordable services, and how can regulators allocate the costs of those services equitably among all users? How can utilities and energy users partner with environmental groups to achieve lasting and beneficial changes in energy?

Ralph Cavanagh
Ralph Cavanagh, Co-Director, Energy Program, NRDC

U.S. electricity sales are not collapsing, but since 2000 the rate of growth has lagged well behind that of the population. Linking utilities’ financial health to escalating commodity sales won’t work any longer. This yields two crucial questions: given declining growth in those commodity sales, how do utilities secure the reasonable revenue certainty required to make enduring provision for reliable and affordable services, and how can regulators allocate the costs of those services equitably among all users? The simple but wrong answer to both questions would be to stop charging for electricity service based on consumption levels. The “all you can eat” pricing model may work well for some businesses, but none have environmental and equity dimensions comparable to electrical generation. The list of alternatives begins with revenue decoupling, which makes utilities indifferent to retail energy sales volumes without abandoning the tradition of volumetric pricing and its incentives for customers to use energy efficiently. Also promising are variable demand charges and minimum bills (which retain volumetric pricing for most customers but ensure that everyone connected to the grid makes an appropriate contribution).
