  • t The Pecan Street Project Introduction I magine that its 2030. And imagine that our city Austin, Texas is leading the evolution of Americas energy delivery system. Residents and business owners across the city are seizing new opportunities to manage their energy use, enabled by modifications to Austin Energys system that allow for a real-time, two-way flow of energy and data. Customers who install solar or other renewable distributed generation equipment at their homes or businesses sell their excess power seamlessly back to the grid. Users are monitoring and managing their use and consumption online and on their phones as easily as they can pay bills or buy a movie ticket. Austin Energy has transitioned to a new pricing system that not only al- T his report is a narrative of the deliberations, assumptions, conclusions and recommenda- lows customers a real-time gauge of the true cost of energy, but also has helped the utility more aggressively control peak demand on Austins hot- tions of the Pecan Street Project test days.

It has reduced its carbon output and other air pollutants beyond changes in the energy market. targeted goals. Widespread deployment of smart water systems has helped customers significantly reduce water usage. A growing portion of the energy used by Austin Energy customers is generated within the city limits and is emissions free, and the utility now has a firm plan to retire all its fossil fuel generation facilities. The utilitys timing was good it began to wean the region from fossil fuels just before their costs skyrocketed (again). In the process, area jobs were saved by repurposing billions in semiconductor investment

Thousands of new jobs have helped established Austin as the clean energy capital of the U.S. The University of Texas leads the nation in clean energy patents and startup companies. And Austin is providing a sustainable clean economy roadmap to cities and utilities around the world. The phrase The Austin Model once used to describe how Austin built its semiconductor industry in the 1980s is now synonymous with clean energy and smart grid. If Austins semiconductor industry made history in the 1980s, what this city has accom- plished since 2010 has rewritten it altogether. This scenario is not as far-fetched as it sounds. In fact, most energy experts think thats where the world is headed. Getting there might not require a total reinvention of todays energy system, as some have suggested, but rather a thoughtful and purposeful evolution that is driven as much by utilities and the communities they serve as by the changing world and technology. The Pecan Street Project was formed to accelerate that evolution in Austin. t Change is Coming Opportunity and Risk S ince its public launch in December 2008, most conversations about the Pecan Street Project have focused on the opportunities presented by leading the countrys energy evolution: the opportunity to reduce carbon; the opportunity to jumpstart widespread renewable generation; the opportunity to start companies, create spinoffs, create jobs. Indeed, the opportunities are enormous. Most countries and cities realize that change is coming to the energy world, whether the cause is a response to global warming, global economics or simply the evolution of technology. Even before the stimulus program injected billions of dollars into the American clean energy industry, significant private investment had already begun flowing. Globally, the race toward a new energy future is underway. Because of Austins history in the technology industry specifically the significant collab- orative effort from which computing-research giants MCC and SEMATECH emerged in the 1980s, kicking off a generation of semiconductor growth in Austins Silicon Hills the Pe- can Street Project team immediately recognized the feasibility and potential payoff of Austin playing a leadership role. The environmental benefits of leading in clean energy are enormous, said Pecan Street Project founding partner Isaac Barchas of UTs Austin Technology Incubator. But to be hon- est, what got everyone so excited about this project early on was that it could be an even big- ger economic payoff for Austin. At a time when Austins technology industries were clearly suffering, charting a path toward new economic opportunity was our primary driver. But while the opportunities are great, the risk of inaction might be even greater. Change is coming in the electricity world, said Pecan Street Project founding partner Jim Marston of Environmental Defense Fund (EDF). Soon, the cost of installing solar will be less 2
  • Are we prepared for the future? T wo of the most likely features of a new energy distribution system are heightened user-controlled power management and increased distributed generation. How well prepared is our energy system for these new features? Austin is ahead of many cities, but it is not yet where it needs to be to imple- ment many of the more advanced concepts. Todays system enables customers to adjust their consumption by modifying their behavior they can program thermostats, automate lighting or use the delay feature on major appliances. But they remain blind to the energy return on such behavior. When energy usage is reduced, customers dont see the cost benefits until their electricity bill arrives. And many important behavior changes such as running the dishwasher or washing machine during off-peak periods help Austin Energy manage peak demand but do not provide the user any cost benefit because electricity costs the same all day. So, some of the pieces of tomorrows active management energy system are being implemented, but theres really no such thing as market-driven user-managed power. Not yet, anyway. In addition, significant challenges emerge when a large amount of distributed generation, such as rooftop solar, is introduced into the current system. Today, a home or business owner can install solar to supplement his propertys energy purchases and he is reimbursed by Austin Energy for any excess power that is pushed back to the utilitys grid. But the systems current pricing structure and two- way capability is, by Austin Energys own account, temporary and not scalable. As solar generation and smart appliances become more prevalent, the utilitys business model, hardware and data
