Item Commercial Building Integrated Photovoltaics: Market and Policy Implications(Center for Energy and Environmental Policy, 1997) Byrne, John; Letendre, Steven; Agbemabiese, Lawrence; Redlin, David; Nigro, RalphItem An International Comparison of the Economics of Building Integrated PV in different Resource, Pricing and Policy Environments: The Cases of the U.S., Japan and South Korea(Center for Energy and Environmental Policy, 2000) Byrne, John; Agbemabiese, Lawrence; Boo, Kyung-Jin; Wang, Young-Doo; Alleng, GerardIn recent years, the Center for Energy and Environmental Policy (CEEP), working with affiliated academic and research institutions in the U.S. and East Asia, has investigated the technical and economic feasibility of using dispatchable photovoltaic (DPV) systems in distributed peak-shaving (PS) applications. In each case, modest amounts of battery storage are used in conjunction with a PV array to achieve firm peak shaving for commercial building operators. Recent investigations have added emergency power as a second function of DPV-PS systems installed on commercial buildings. This paper reports on CEEP’s latest studies carried out in the US, Japan and South Korea which offer a cross-national review of the performance of dual-function DPV systems designed to serve peak shaving and emergency power needs of the commercial buildings sector. The market assessment results for each country are derived from PV Planner, a spreadsheet analytical tool developed at CEEP to run simulations of building integrated PV applications under different resource, pricing and policy environments. The analyses in all three countries rely on electricity load data from actual buildings, resource data for specific national locations, and actual electricity tariffs in use in each country. The paper recommends policies that can enable PV to compete as an energy service application in an international market.Item Photovoltaics as an Energy Services Technology: A Case Study of PV Sited at the Union of Concerned Scientists Headquarters(Proceedings of the American Solar Energy Society 98 Conference, 1998-06) Byrne, John; Agbemabiese, Lawrence; Bouton, Darren; Kliesch, James; Letendre, Steven; Aitken, Donald W.This paper presents a technical and economic analysis of the Union of Concerned Scientists' (UCS) 2.1kW photovoltaic (PV) array located on the roof of their Cambridge headquarters. We analyze the technology from a variety of different perspectives. The system as it currently exists is primarily an energy supply technology. Alternatively, the system could be reconfigured with the addition of a modest amount of storage to serve energy management functions, primarily offering firm, peak-shaving benefits on a daily and yearly basis. This value would be enhanced with better energy management by UCS of their heat pump cycles. We also analyze the economics of the UCS PV array serving an additional emergency power function. The results of our analysis indicate that the economic value of the UCS PV array would be optimized in a configuration that serves all three functions: energy supply, energy management, and emergency power. In fact, we estimate that the payback period for the system configured in this fashion would be approximately five years.
