Cover of Making the Economic Case for Small-Scale Distributed Wind — A Screening for Distributed Generation Wind Opportunities report

Distributed Generation Wind Opportunities
SEAC staff members Alicen Kandt, Elizabeth Brown, and Jeffrey Dominick recently published "Making the Economic Case for Small-Scale Distributed Wind — A Screening for Distributed Generation Wind Opportunities" (PDF 416 KB) for the WindPower 2007 conference. This study was an offshoot of a previous assessment, which examined the potential for large-scale (greater than 50 MW) wind development on occupied federal agency lands. The study did not find significant commercial wind development opportunities, primarily because of poor wind resource on available and appropriately sized land areas, or land use or aesthetic concerns. The study did identify a promising —but less common — distributed generation (DG) development option. This follow-up study documents efforts to identify economic DG wind projects at a select group of occupied federal sites by an NREL/Global Energy Concepts team. The benefits and barriers of DG are discussed, and the screening methodology and results are included. The report concludes with generalizations about the screening method and recommendations for improvement and other potential applications for this methodology.

Cover of Modeling the National Potential for Offshore Wind report

The Potential for Offshore Wind
Analysts Walter Short and Patrick Sullivan recently published "Modeling the National Potential for Offshore Wind" (PDF 3.2 MB) for the WindPower 2007 Conference in Los Angeles. There is a national interest in the potential of offshore wind power due to the growing concern about climate change and the corresponding need for renewable energy. Offshore wind power is attractive due to the large and high-quality resource off the U.S. coasts as well as that offshore wind farms can be sited relatively close to load centers – more than half the population of the United States lives within 50 miles of an ocean or Great Lake – lowering transmission losses and expense. Additionally, wind farms off the coast of Europe have successfully demonstrated the technology. Offshore wind farms, however, have high up-front costs and are not seen as economical in the near term. There is interest, therefore, in examining under what economic, social, and technological conditions offshore wind becomes viable. This paper contributes to this examination, using the Wind Deployment System (WinDS) model.

Cover of Costs and Emissions Associated with Plug-In Hybrid Electric Vehicle Charging in the Xcel Energy Colorado Service Territory report

PHEVs and Utilities in Colorado
Analysts Paul Denholm, Tony Markel, and Keith Parks recently published "Costs and Emissions Associated with Plug-In Hybrid Electric Vehicle Charging in the Xcel Energy Colorado Service Territory," (PDF 551 KB). The combination of high oil costs, concerns about oil security and availability, and air quality issues related to vehicle emissions are driving interest in "plug-in" hybrid electric vehicles (PHEVs). PHEVs are similar to conventional hybrid electric vehicles, but feature a larger battery and plug-in charger that allows electricity from the grid to replace a portion of the petroleum-fueled drive energy. The use of PHEVs would represent a significant potential shift in the use of electricity and the operation of electric power systems. Electrification of the transportation sector could increase generation capacity and transmission and distribution (T&D) requirements, especially if vehicles are charged during periods of high demand. This study is designed to evaluate several of these PHEV-charging impacts on utility system operations within the Xcel Energy Colorado service territory.

Cover of Implications of Carbon Regulation for Green Power Markets

Green Power Markets and Carbon Regulation
NREL analysts, along with Ed Holt and Associates Inc., recently published "Implications of Carbon Regulation for Green Power Markets" (PDF 983 KB). While the implementation of policies to control or reduce carbon emissions is likely to provide market benefit to renewable energy sources by increasing the cost of production from carbon-emitting energy sources, the impact on voluntary renewable energy purchase ("green power") markets is not as clear. Because voluntary purchases are often premised on the ability to make environmental claims, the green power market could be negatively impacted if carbon policies are not properly structured. In this report, the authors review carbon regulation programs under development in the Northeast and California, as well as the experience in the European Union, where carbon is already regulated, and discuss the potential implications of these programs for the types of environmental claims currently made by commercial and institutional green power purchasers. The authors also explore the potential interaction between voluntary renewable energy purchase markets and voluntary carbon markets, such as the Chicago Climate Exchange. The report ends with policy options for regulators and other decision makers to consider in designing carbon policies that will enable carbon markets and voluntary renewable energy markets to work together.

Cover of The Technical Potential of Solar Water Heating to Reduce Fossil Fuel Use and Greenhouse Gas Emissions in the United States

Reducing Fossil Fuel Use and Greenhouse Gas Emissions with Solar Water Heating
NREL also published "The Technical Potential of Solar Water Heating to Reduce Fossil Fuel Use and Greenhouse Gas Emissions in the United States" (PDF 571 KB). Use of solar water heating (SWH) in the United States grew significantly in the late 1970s and early 1980s, as a result of increasing energy prices and generous tax credits. Since 1985, however, expiration of federal tax credits and decreased energy prices have virtually eliminated the U.S. market for SWH. More recently, increases in energy prices, concerns regarding emissions of greenhouse gases, and improvements in SWH systems have created new interest in the potential of this technology. SWH, which uses the sun to heat water directly or via a heat-transfer fluid in a collector, may be particularly important in its ability to reduce natural gas use. This report provides an overview of the technical potential of solar water heating to reduce fossil fuel consumption and associated greenhouse gas emissions in U.S. residential and commercial buildings.

Web Image of Projected Benefits of Federal Energy Efficiency and Renewable Energy Programs – FY 2008 Budget Request

GPRA Benefits Analysis Report
The Office of Planning, Budget, and Analysis (PBA) has released its FY 2008 benefits analysis report, "Projected Benefits of Federal Energy Efficiency and Renewable Energy Programs – FY 2008 Budget Request." This report summarizes the results of the benefits analysis, which was led by NREL, of the U.S. Department of Energy's (DOE) Office of Energy Efficiency and Renewable Energy (EERE) programs, as described in the FY 2008 budget request and developed under the Government Performance and Results Act (GPRA) of 1993. EERE estimates benefits for its overall portfolio and for each of its nine Research, Development, Demonstration, and Deployment (RD3) programs. Benefits for the FY 2008 budget request are estimated for the midterm (2008-2030) and long term (2030-2050). EERE annually assesses the contribution of its work to DOE's goals of providing affordable, clean, and reliable energy. Two energy market models are used in this assessment—one that looks in detail at the midterm (through 2030) and one that looks more generally at trends in the long term (through 2050).

Cover of Updated U.S. Geothermal Supply Characterization

Geothermal Analysis Publications Released
The National Renewable Energy Laboratory (NREL), along with Black Mountain Technology, recently published "Updated U.S. Geothermal Supply Characterization" (PDF 877 KB). This paper, presented at the 32nd Workshop on Geothermal Reservoir Engineering at Stanford University, documents the approach taken to characterize and represent an updated assessment of U.S. geothermal supply for use in forecasting the penetration of geothermal electrical generation in the National Energy Modeling System (NEMS). This work is motivated by several factors: The supply characterization used as the basis of several recent U.S. Department of Energy (DOE) forecasts of geothermal capacity is outdated; additional geothermal resource assessments have been published; and a new costing tool that incorporates current technology, engineering practices, and associated costs has been released.

Cover of Preliminary Technical Risk Analysis for the Geothermal Technologies Program

NREL analysts, along with Princeton Energy Resources International (PERI), also published "Preliminary Technical Risk Analysis for the Geothermal Technologies Program" (PDF 1.4 MB). This report explains the goals, methods, and results of a probabilistic analysis of technical risk for a portfolio of R&D projects in the DOE Geothermal Technologies Program. The main challenge in the analysis lies in translating R&D results to a quantitative reflection of technical risk for a key Program metric: levelized cost of energy (LCOE). This requires both computational development (i.e., creating a spreadsheet-based analysis tool) and a synthesis of judgments by a panel of researchers and experts of the expected results of the Program's R&D.

Analysts Meet With Stakeholders
NREL's Energy Forecasting and Modeling group hosted a one-day meeting on March 21 kicking off a project to expand the Stochastic Energy Deployment System (SEDS) model to incorporate energy end-use sectors, energy supply sources, and additional energy conversion sectors. SEDS, a capacity expansion forecasting model of the U.S. energy market, developed initially for the electricity sector, represents the impacts of major market drivers and explicitly incorporates uncertainty. Once complete, the model will be used to examine the implications of possible energy futures and to assist DOE in assessing the impact of its research and development investments in energy technologies. Analysts from the following organizations attended the meeting and will contribute their expertise to the project: DOE/EERE/PBA, Argonne National Laboratory, Lawrence Berkeley National Laboratory, National Energy Technology Laboratory, Oak Ridge National Laboratory, and Pacific Northwest National Laboratory.

In mid-March, NREL analyst Ron Benioff testified before the Colorado Senate Agriculture, Natural Resources, and Energy Committee on the subject of renewable energy development on state lands.

NREL Publishes Analysis Reports
The National Renewable Energy Laboratory (NREL) recently published "Regions in Energy Market Models" (PDF 1.3 MB). This report explores the different options for spatial resolution of an energy market model — and the advantages and disadvantages of models with fine spatial resolution. It examines different options for capturing spatial variations, considers the tradeoffs between them, and presents a few examples from one particular model that has been run at different levels of spatial resolution.

NREL analysts also published "Understanding and Informing the Policy Environment: State-Level Renewable Fuels Standards" (PDF 612 KB). Renewable fuels standard (RFS) policies are becoming a popular public policy mechanism for developing the market for renewable fuels in the transportation sector. During the past decade, U.S. states and several countries began implementing these more market-based (less command and control) policies to support increased biofuels production and use. This paper presents an overview of current and proposed U.S. state-level policies, as well as selected electric sector policies and international fuel standard policies. Understanding and building on the experiences from these previous policies can improve the policy mechanism and further develop a market for renewable fuels to meet the goals of improved economy, environment, and fuel self-sufficiency.

The Lab also published "Experience Scaling-Up Manufacturing of Emerging Photovoltaic Technologies" (PDF 726 KB). This report examines two important generic photovoltaic technologies at particularly revealing stages of development, i.e., the stages between R&D and stable commercial production and profitable sales. Based on two historical cases, it attempts to shed light on the difference between: 1) costs and schedules validated by actual manufacturing and market experience, and 2) estimated costs and schedules that rely on technology forecasts and engineering estimates. The experience reported here can be instructive to those managing comparable efforts, and to their investors. It can also be instructive to R&D managers responsible for positioning such new technologies for commercial success.

Groups Launch Energy Collaborative Analysis Initiative
A multiorganizational group has initiated a collaborative effort with federal and state officials and research organizations to identify opportunities to enhance collaboration on energy analysis — an effort that would ultimately inform policy making. Through the development of a shared strategy for addressing high-priority energy issues, the Energy Collaborative Analysis Initiative (ECAI) aims to inform decision-makers, improve analysis assumptions and methodologies, and increase interagency collaboration. These analysis collaborations may ultimately expand to include participants in other sectors as well (private sector, nongovernmental organizations, etc.).

For more information on the priority energy topics, background on the collaborators, and outcomes from the inaugural workshop, visit the ECAI website.

Cover of Burbank Transportation Management Organization: Impact Analysis

NREL Publishes Analysis Reports
The National Renewable Energy Laboratory (NREL) recently published the "Photovoltaic Incentive Design Handbook" (PDF 1.0 MB). This handbook is designed for agencies and utilities that offer or intend to offer incentive programs for customer-owned PV systems. Its purpose is to help select, design, and implement incentive programs that best meet programmatic goals. The handbook begins with a discussion of the various available incentive structures and then provides qualitative and quantitative tools necessary to design the most appropriate incentive structure. It concludes with program administration considerations.

NREL also recently published "Burbank Transportation Management Organization: Impact Analysis" (PDF 472 KB). The Burbank Transportation Management Organization (BTMO) — a private, membership-based, nonprofit organization in California, dedicated to traffic reduction and air quality improvement — contracted with NREL to analyze its member programs and their benefits and effects. This report uses trip data collected by the BTMO, and defines and implements a methodology for quantifying non-traffic benefits such as gasoline savings, productivity, and pollution reduction.

Analysts Meet With Stakeholders
As part of an NREL initiative, Doug Arent is meeting this month with a group of world-renowned scientists and energy experts to discuss what type of energy (and perhaps, more broadly, general economic) infrastructure will be sustainable in 100 years. Hosted by the Santa Fe Institute, the meetings aim to answer a few fundamental questions: Given long-lived infrastructure and competing drivers for change in the energy sector, how might our energy (food or other goods) economy evolve during the next 100 years? And what scale(s) will emerge as truly sustainable solutions? This core team will define the vision and possible pathways for continued research — we'll continue to update you through this newsletter.
