Electric Utilities fuel use and responsiveness to fuel prices
Energy Economics, 2014Co-Authors: Daniel C Matisoff, Douglas S NoonanAbstract:This research tests the impact of changes in fuel price to explain fuel use by Electric Utilities. We employ a three-stage least squares model that explains changes in fuel use as a function of changes in three fuel prices. This model is repeated across sub-samples of data aggregated at the plant level and operating holding company level. We expect that plants and holding companies reduce fuel use when fuel prices rise. Several fuel substitution effects within and across plants and holding companies are demonstrated, as well as several frictions. At the plant level, higher prices of natural gas lead to less natural gas consumption, less coal consumption, and more fuel oil consumption. At the operating holding company level, results demonstrate the inelasticity of coal use and the increases of natural gas in response to higher coal prices. Subsamples demonstrate heterogeneity of results across different plants. Results emphasize that technological, market, and regulatory frictions may hinder the performance of energy policies.

Fuzzy Decision Support System for Electric Utilities Fault Comprehensive Evaluation in Electric Control System
2006 IEEE Conference on Robotics Automation and Mechatronics, 2006Co-Authors: Yuan Haiwen, Yuan Haibin, Li XingshanAbstract:Aim at existing fault evaluation practice for Electric Utilities diagnosis and maintenance prediction, a novel fuzzy decision support system (FDSS) architecture based on simulation platform is presented. The specialty is that the information of all the fault factors that influence component failure are simulated through the platform according to specific requirement. FDSS architecture and theoretical analysis model using fuzzy decision engine method is presented, all factors used for decision making are taken into consideration and determined by the severity of failure through corresponding consequence analysis using fuzzy algorithm. A simplified application evaluation process is introduced to show the feasibility and potential benefits. The proposed FDSS can deal with test or field evaluation process and can achieve comprehensive evaluation result, and the result can be used for Electric Utilities diagnosis and maintenance guidance as well as provide reference for further operation in Electric control system design suggestion

Fuel cells, energy system evolution and Electric Utilities
International Journal of Hydrogen Energy, 1994Co-Authors: Hans Holger RognerAbstract:Spurred by recent technology advances, Utilities have begun to include fuel cells into their menu of future Electricity generating options. Latest studies suggest competitiveness with diesel-Electric generators in those parts of utility service areas that are not connected to the integrated Electricity system. These early market niches are key for the commercialization of fuel cell technology and must not be ignored. From the perspective of the overall energy system evolution, however, Electric Utilities are not the real long-term target market for fuel cells. The most promising market will be the transportation sector while Electric Utilities are likely to become both Electricity and hydrogen producers. © 1994.

Electric VEHICLES AS A NEW POWER SOURCE FOR Electric Utilities
Transportation Research Part D-transport and Environment, 1997Co-Authors: Willett Kempton, Steven E. LetendreAbstract:Abstract Electric-drive vehicles, whether fueled by batteries or by liquid or gaseous fuels generating Electricity on-board, will have value to Electric Utilities as power resources. The power capacity of the current internal combustion passenger vehicle fleet is enormous and under-utilized. In the United States, for example, the vehicle fleet has over 10 times the mechanical power of all current U.S. Electrical generating plants and is idle over 95% of the day. Electric Utilities could use battery vehicles as storage, or fuel cell and hybrid vehicles as generation. This paper analyzes vehicle battery storage in greatest detail, comparing three Electric vehicle configurations over a range of driving requirements and Electric utility demand conditions. Even when making unfavorable assumptions about the cost and lifetime of batteries, over a wide range of conditions the value to the utility of tapping vehicle Electrical storage exceeds the cost of the two-way hook-up and reduced vehicle battery life. For example, even a currently-available Electric vehicle, in a utility with medium value of peak power, could provide power at a net present cost to the vehicle owner of $955 and net present value to the utility of $2370. As an incentive to the vehicle owner, the utility might offer a vehicle purchase subsidy, lower Electric rates, or purchase and maintenance of successive vehicle batteries. For a utility tapping vehicle power, the increased storage would provide system benefits such as reliability and lower costs, and would later facilitate large-scale integration of intermittent-renewable energy resources.
