Última The Economics of Wind Power with Energy Storage AgEcon Benitez, Pablo C.; Dragulescu, Lilianna; van Kooten, G. Cornelis. We develop a nonlinear mathematical optimization program for investigating the economic and environmental implications of wind penetration in electrical grids and evaluating how hydropower storage could be used to offset wind power intermittence. When wind power is added to an electrical grid consisting of thermal and hydropower plants, it increases system variability and results in a need for additional peak-load, gas-fired generators. Our empirical application using load data for Alberta’s electrical grid shows that 32% wind penetration (normalized to peak demand) results in a net cost increase of $C5.20/ MWh, while 64% wind penetration could result in an increase of $12.50/MWh. Costs of reducing CO2 emissions are estimated to be $41-$56 per t CO2 . When...

British Columbia’s electricity grid is comprised primarily of hydroelectric generating assets. The ability to store water in reservoirs is a significant advantage for the province allowing it to import from Alberta when prices are favourable. Alberta, has a heavily fossil-fuel based electricity portfolio, but has seen substantial growth in its wind energy capacity. However this variable energy technology impacts the province’s grid operations. Wind energy is both variable and uncertainty. However, wind energy in Alberta can be stored via BC’s reservoir systems. In this paper, we examine the extent that drought impacts the both overall operating costs as well as the cost of reducing CO2 emissions. We model the Alberta and BC interconnected grids varying...

Ano: 2010 URL: http://purl.umn.edu/59701 Wind Power: The Economic Impact of Intermittency AgEcon van Kooten, G. Cornelis. Wind is the fastest growing renewable energy source for generating electricity, but economic research lags behind. In this study, therefore, we examine the economics of integrating large-scale wind energy into an existing electrical grid. Using a simple grid management model to investigate the impact of various levels of wind penetration on grid management costs, we show that costs of reducing CO2 emissions by relying more on wind power depend on the generation mix of the existing electricity grid and the degree of wind penetration, with costs ranging from $21 to well over $1000 per tonne of CO2 reduced. Costs are lowest if wind displaces large amounts of fossil fuel production and there is some hydroelectric power to act as a buffer. Hydro capacity has...
