The authors also acknowledge the contribution of Rob Davis and Greg Mordini of Forest Energy Corporation for their assessment of biomass-fi red steam production. This study was a collaboration between the Laboratory and the County, and the authors would like to acknowledge the contributions of several staff members at the Department of Public Utilities: Thomas Biggs, Robert Monday, Julie Williams-Hill, Gerald Martinez, and Lourna Ramirez. The following members of the Laboratory staff provided electrical load estimates for potential future Laboratory projects. Their input was essential in developing the load growth forecasts: Don Bryant, Mel Burnett , Duane Nizio, David Powell, Rick Rivera, Joseph Sanchez, Grant Stewart, and Bruce Takala. The authors would especially like to thank Michelle Marean, Gerry Runte, and Mona Valencia of the Infrastructure Planning Offi ce for their invaluable contribution in providing the data analyses, photovoltaic system models, assessments of renewable technologies, and endless narrative edits to create a crisp readable document. A debt of gratitude is also owed to the following individuals who worked arduously to compile, produce, and review this study: Annabelle Almager, Michael Bodelson, Jeanne Bowles, Larry Chigbrow, and Joan Stockum. Lastly, this study could not have been completed without the support of the following Laboratory managers: Tom McKinney, Jerry Ethridge, Ken Schlindwein, Don O’Sullivan, Cindy Hayes, and Andy Erickson.

These benefi ts are the direct under increasing pressure to add renewables result of a unique power pooling arrangement to its supply portfolio. In 2007, the Los created between the two parties in 1985 – Alamos County Utility Board mandated that the Los Alamos Power Pool. The contract the Los Alamos County Department of Public that governs the Power Pool’s cost sharing, Utilities seek opportunities to “go green.” In management, and operations, the Los Alamos early 2008 the DOE issued an Order1 (DOE County/Department of Energy, Electric Energy O 430.2B) requiring all of its sites to install and Power Coordination Agreement (ECA), on-site renewable generation. At present, the enabled Los Alamos County to purchase only renewable energy source planned for the fossil-fueled and hydroelectric generation Power Pool is the County’s installation of a capacity in the mid-1980s through the sale third unit at Abiquiu Dam in FY09. This study of tax-exempt municipal revenue bonds, explores the practicality of renewable energy which retire in 2015. For the last twenty-three for the Power Pool, beyond the addition of years, the County’s ownership of a portfolio the Abiquiu hydroelectric project, in order to of generation assets has sheltered the County meet both the DOE and County requirements; and the Laboratory from much of the inherent ensure that the costs of production for market risks associated with the wholesale renewables remain competitive with the power market. current costs of production in the Power The power pooling agreement was amended Pool (the majority of which are fossil fueled); in 2006 with the option for additional and stabilize the future cost of energy for extensions in rolling fi ve-year terms.
