Economic Costs of Managing of an Electricity Grid with Increasing Wind Power Penetration
Beginning of article
We examine the impact of policy choices, including a carbon tax, on the optimal allocation of power across different generation sources and on future investments in generating facilities. The main focus is on the Alberta power grid, as it is heavily dependent on fossil fuels and has only limited ties to other power grids, although the model could be extended to larger (and even multiple) grids. The results indicate that, as wind penetrates the extant generating mix characterizing the grid, cost savings and emission reductions do not decline linearly but at a decreasing rate. However, if flexibility is allowed, then, as the carbon tax increases to C$40/tCO2 or above, existing coal plants …
