In this lecture we pose the problem of sustainable electricity services as a novel systems engineering design problem. We briefly summarize today's operating and planning practices and explain why these need fundamental changing in order to enable qualitatively different electricity services. In particular, we suggest that many new resources have characteristics, which are not generally known to the system operators, and are, therefore, currently not relied on for managing supply and demand in an often-congested electric network. The new resources are also highly variable and, as such, do not lend themselves to static feed-forward scheduling without near-real time automated feedback. Instead, a transformation of this operating and planning mode into an interactive multi-temporal, multi-spatial and multi-contextual system management is needed to accommodate ever-changing system conditions, often driven by many distributed actions. In order to enable a complex system with often-conflicting functionalities, such as reliability, security, short- and long-term efficiency, and sustainability, one must rely on prediction, adaptation and adjustments by all.

Extending the Grid: Transmission Siting Issues and How to Resolve Them

Abstract:
In energy planning circles, in all sectors of the electric industry, in state utility regulatory commissions, and on Capitol Hill, we’ve heard a lot of discussion over the past year about changing the traditional paradigm surrounding the building of electric transmission in order to extend the country’s electric grid. Recently, the talk has moved into the arena of action. In the U.S. House and Senate, there are numerous bills that propose legislative changes to how we plan and site transmission in America—and how we allocate the cost of it. The Waxman-Markey Climate Change bill, which was passed by the U.S. House of Representatives last year, includes such changes. All of the various bills differ one from the other. One similarity among them all is that the federal government’s role (in the person of the Federal Energy Regulatory Commission) would be expanded and the states’ role would be reduced.

Why is there a growing consensus for change? What’s wrong with how we’ve always done things? (How have we always done things?) Is there a problem here? What are the proposed changes? What are we trying to accomplish with change? What is the best proposal being put forward? Who likes the changes? Who stands to benefit from the changes? Will there be any losers? Ms. Kelly intends to answer these questions during her presentation. She will also discuss what is likely to happen to the U.S. electric grid if we do not see any legislative change from Congress.

Economic Analysis of the Solar Industry: Achieving Grid Parity

Annie Hazlehurst, Graduate Student, Stanford GSB

Wednesday, October 28, 2009 | 04:15 PM - 05:15 PM | Building 420, Room 40 | Free and Open to All

The economics of solar systems will drive long term adoption and market viability. Today, the U.S. and many other countries continue to subsidize the cost of solar systems and incentivize adoption through standards such as RPS. If solar is going to contribute meaningfully to our energy future, the economics must favorably compare to alternative sources of energy on a levelized cost basis. When and how will we achieve grid parity? The talk will cover where we are today and where we need to get for solar to be a primary source of global energy generation.

The Stanford panelists will discuss a number of important themes and issues about energy use, impacts, and opportunities as we begin the transition to a low emission energy future. Panelists will consider economic viability, political will, resource constraints, and environmental impacts of various energy technologies at scale. They will discuss tradeoffs and how decision makers may seek co-benefits and avoid unintended consequences when making choices.

A Strategy for Exploiting Unconventional Gas Resources and Mitigating Greenhouse Gas Emissions

Mark Zoback, Stanford University

Wednesday, May 20, 2009 | 04:15 PM - 05:15 PM | Building 420, Room 40 | Free and Open to All

May 20, 2009 - Mark Zoback, professor of Geophysics at Stanford University, discusses recent developments in natural gas extraction that enable cost-effective carbon capture and storage to mitigate greenhouse gas emissions. Zoback presents the expected benefits of replacing coal with electrical power generation in the U.S., which would reduce CO2 emissions and other pollutants while providing sufficient energy to meet demand, using existing technologies, and providing economic incentives for carbon capture and sequestration. He also reviews the current CO2 sequestration projects within the U.S. and the potential for enhancing these projects.

In the past decade, the use of gas shales grew eight-fold, and in the past 3-5 years, $40 billion was invested in its production. However, the decline in gas prices led to a major decrease in their development. Zoback argues that the production of gas shales offers a unique opportunity for the use of coal bed methane. Even though the Energy Information Administration predicts that there will be minimal growth in unconventional gas production over the next 20 years, the gas industry expects much higher growth rates. Zoback believes that natural gas will have to be a part of the transition away from fossil fuel in the U.S. However, gas shale reservoirs still have a number of uncertainties, including the mechanical response of rocks during slick-water fracturing, the evolution of mechanical properties during production, gas adsorption and desorption, and the controls on permeability during fracturing.

Transforming Our Energy Economy: The Role of Renewable Energy

Dr. Dan E. Arvizu, National Renewable Energy Laboratory

Wednesday, April 1, 2009 | 04:15 PM - 05:15 PM | Building 420, Room 40 | Free and Open to All

April 1, 2009 - Dan Arvizu, director of the Department of Energy's National Renewable Energy Laboratory (NREL), discusses the current state of renewable energy technology and implementation in the U.S., as well as potential advancements in the near future. He focuses on the need to increase energy efficiency and to expand the renewable energy marketplace in the United States. A recent increase in the laboratory's budget is promising, but they also need to increase the speed of technology uptake. Arvizu argues that local economics are encouraged by green techology. If the United States begins on the path to sustainable energy use, then these incremental changes will bring about a transition within the energy sector. The key challenges are implementing renewable energy at scale, displacing petroleum fuels, and reducing the energy demands of industry. He focuses on buildings as one of the biggest targets for emissions reduction because they are big emitters and there are low-cost options to reduce their carbon output. Wind and solar are also becoming more viable renewable energy sources, but Arzivu expresses a need to improve current technologies. NREL is positioned to address the large-scale deployment issues that also currently exist. The laboratory planning to implement different combinations of alternative technologies in each country where it works, based on their energy sector's adaptability to the various technologies.
