75 MW IPP Project – Russia
For a Russian project developer and ABB, PERI managed the preparation of a technical and economic feasibility study for a utility-scale wind power plant located in the vicinity of St. Petersburg, Russia. The $1.3 million study was supported by the United States Trade and Development Agency, General Electric, and other commercial participants. The study included: wind measurements and resource analysis, plant layout and preliminary design, power system integration analysis, market research, and an environmental assessment. As part of this study, PERI analyzed the financial feasibility of the project, and identified candidates including major companies in the St. Petersburg area for power off-take under long-term Power Purchase Agreements. PERI also identified available grants, tax credits, and environmental subsidies and developed other forms of incentives that could lower the cost of generating wind power and narrow the tariff gap between the wind and conventional power generation technologies in Russia. In addition, various sources of debt and equity financing were identified. PERI's business and financial cash-flow analysis models were used to produce project proformas that are being used to obtain needed financing. PERI and the team of American and Russian firms have developed a detailed business plan that is now being implemented. Click here to view the Feasibility Study report.
Vashon-Maury Island Energy Sustainability Study
For the Institute for Environmental Research and Education, a nonprofit organization with Offices in Washington State, PERI conducted a renewable resource and technology assessment to examine the island’s renewable resources, applicable technologies and costs for electric power generation, and for liquid fuel and hydrogen production. Biomass, wind, solar, tidal, and geothermal resources were assessed, and generation/production costs were projected. Production and use of hydrogen for stationary and mobile power generation was also examined.
Integration of Hydropower with High Penetration of Wind and Biomass
This study examined the high penetration of usable wind and biomass power plants in the Vermont, Green Mountain Power and New England Power Pool service areas. Power system integration analysis addressed technical and economic issues and realistic limits for installing up to 900 hundred megawatts of distributed wind power plants and up to several hundred megawatts of new biomass plants operating in conjunction with existing hydropower plants in the Green Mountain Power, New England Power Pool, and Hydro-Quebec service area. Specific objectives of the study were to evaluate the effects of high penetration levels of renewable energy on the grid of Vermont (and adjoining areas) by 2010, operating in the restructured distributed utility environment, to determine: (1) transmission and distribution grid systems changes needed, (2) grid operation and control issues, (3) ways to minimize increases in the cost of energy to the consumer, (4) potential reductions in regional CO2 emissions, and (5) the incremental cost of renewable energy capacity additions. The study showed the technical and economic benefits of using seasonal variations of wind and hydro resources for mutual support.
Economic Study of BioEnergy Production from Digesters at Dairies in California
From summer 2007 into 2008, under subcontract to SAIC, for the California Energy Commission, PERI analyzed actual and projected energy production at dairy farms in California. Specifically, PERI reviewed nine small dairy digester systems that received grants under the California Dairy Power Production Program (DPPP). After reviewing actual power cases, PERI projected project layout and calculated levelized costs of energy for plants producing no subsidy power and pipeline-quality gas, enhanced environmental quality power, and enhanced environmental quality pipeline-quality gas, as well as investigated various special tax and financial sensitivities.
Economics of Wind Power Projects for Electric Cooperatives
For the National Rural Electric Cooperative Association (NRECA), current, PERI provided unbiased information on the real cost of this generation source. In addition, since wind energy can provide added value to consumers in the form of environmental benefits (“green” attributes), PERI developed information for electric cooperatives to help them understand if and how so-called “green power” programs can work for them, and what the experience of other utilities, public and private, has been to date. Finally, because there are significant differences and restrictions in the use, availability, and applicability of incentives among various types of utilities and independent power producers, PERI identified and quantified the opportunities available specifically for electric cooperatives to utilize such incentives. Specifically, PERI interpreted the limitations and value of the incentives as they apply to electric cooperatives. In addition, PERI explored the use of project cashflows to demonstrate the financial impact of various incentives.
Distributed Wind Assessment
PERI prepared a report for the U.S. Department of Energy-sponsored National Wind Coordinating Council to address issues associated with the adoption of distributed wind power. Key task activities performed included collection and analysis of data on domestic and European wind energy experience; analysis of distributed wind project costs and interconnection requirements; analysis of potential "distributed utility" benefits; evaluation of the European distributed wind market; critical review of infrastructure and industry needs in U.S.; detailed analysis of economic impacts of distributed wind in the U.S.; and preparation of a final report.
Renewable Energy Technology Characterization
PERI was commissioned by the Electric Power Research Institute (EPRI) with funding from the U.S. Department of Energy, to analyze and assess the likely cost factors and performance improvements projected through 2030 for wind, biomass, photovoltaic, solar thermal and geothermal energy technologies. The study involved PERI economic and financing models adapted to allow technology comparisons. PERI focused on wind technology used for large, domestic windfarm applications (horizontal axis wind turbines within a central station environment). In addition to characterizing the advances made in the design, siting, installation, operation, and maintenance of turbines (e.g., on a single-unit level; on an entire wind farm), PERI also addressed transmission requirements coupled with environmental impacts and resultant mitigation schemes.
Hydropower Technology Assessment and Development
PERI is working under contract to the National Renewable Energy Laboratory (NREL) to provide technical assistance to the DOE hydropower program planning and execution staff. PERI personnel are working with the technology development teams at Oak Ridge National Laboratory and the Idaho National Energy Laboratory to assess advanced technologies that provide superior environmental performance, with high energy conversion efficiency. PERI has assessed the U.S. hydropower resource potential and developed future estimates of hydropower-generated electricity from undeveloped, redeveloped, and upgraded hydropower facilities.
Wind Systems Technology Analysis
PERI provided and analyzed data for the National Renewable Energy Laboratory (NREL) on wind technology cost, reliability, and performance. The project was organized into three tasks: 1) provide option Planning and Analysis Support to assist NREL program managers in responding to DOE program planning requirements. Activities included research on program rationale and justification, recommended program milestones and associated narratives, and analyses of the integration of wind into utility planning scenarios. 2) Perform a systems study which characterizes energy capture, reliability and system cost, focusing on specific domestic and foreign turbine designs. 3) Develop utility financial analysis tools to help NREL develop an understanding of stakeholder requirements for renewables.
Renewable Industry Status Overview
For the Electric Power Research Institute, PERI prepared a comprehensive summary of the status of the renewable energy industry. The technologies covered in the report were: wind, photovoltaics, biomass power, geothermal, and solar thermal. PERI compiled a list of industry members for each technology and developed a format and data structure for industry profiles. PERI also compiled individual industry profile information, prepared report outline and individual technology overview chapters, and produced a final report for publication.

Renewable Energy Systems and Energy Efficiency Benefits Model
PERI developed a benefits analysis framework, for the United States Department of Agriculture (USDA), to quantify the expected contributions of the Renewable Energy Systems and Energy Efficiency Improvements Program, which was authorized by Section 9006 of the 2002 Farm Bill. In order to meet their benefits reporting requirements, PERI developed the Renewable Energy Systems and Energy Efficiency Improvements Benefits Model (BENMOD) for the benefits metrics calculations. PERI also helped determine which metrics to include in the benefits reporting, formed a consensus on the assumptions and conversion factors used to calculate these benefits, and prepared the report to document the methodology used to arrive at the expected benefits of the program. Three classifications of benefits are calculated under this framework: economic, environmental, and energy security metrics.
Supplying Advanced Materials and Components for Wind Power Systems
PERI prepared a study on manufacturing and materials to address the need for high volume, low cost components for wind turbines for DOE's Office of Industrial Technologies. This was presented by Daniel Ancona as the key note address at a technology forum for technologists and executives from aluminum, steel, chemicals, fiberglass, plastics, and metal forming and casting industries with wind turbine manufactures, to identify useful new materials and manufacturing processes for markets through 2010.
Renewable Resources Technology Assessment
For the Empire State Electric Energy Research Corporation (ESEERCO), PERI examined ten resource categories, including 15 technology/resource applications, to determine resources with the highest potential for market deployment by utilities. Technologies identified for further analysis included wind plants, remote off-grid and distributed photovoltaics, waste wood, tire-derived fuel, landfill gas, MSW burning, and hydro. PERI developed a database of cost and performance characteristics specific to New York State for these resources, as well as an assessment of financial and other barriers to market deployment and developed recommendations for appropriate ESEERCO RD&D activities to address these barriers.
Analytic Services for the U.S. DOE, Office of Power Technologies (OPT)
PERI is assisting the National Renewable Energy Laboratory (NREL) in its analytical support to the U.S. DOE’s Renewable Energy R&D Program as the primary lead contractor for performance measurements, analysis, and technology characterization and assessment. The focus of PERI’s work is on evaluation of program benefits, development of technology data, and modeling of market penetration through the Renewable Energy Technologies Emerging Market (RETEM) model. Technology data have also been used in working with EIA and NEMS modeling for the Annual Energy Outlook. PERI utilizes a benefits analysis and tracking and spreadsheet that it created to catalogue all input data and calculate benefits metrics for the OPT GPRA submission.
Power Technologies Data Book
For the U.S. Department of Energy Office of Power Technologies (Through Subcontract to NREL), PERI led the effort to develop comprehensive technology profiles of renewable supply-side electric technologies, including wind, biopower, photovoltaics, advanced hydro power, concentrating solar power, geothermal, hydrogen, and solar buildings. The profiles included technology descriptions, current and projected trends for cost, performance, and market status.
