This paper recognises that electricity generation accounts for a large greenhouse gas (GHG) emissions share, as a result, it is noted that this is one sector that needs to be decarbonised. From a US perspective, the author examines a number of issues related to greater uptake of renewable energy for grid-connected electricity generation. An in-depth analysis of regulatory practices adopted by different states and regions to address these issues is provided. The paper evaluates policy options for 'greening the grid’ and provides a number of specific recommendations. The author advocates for an integrated regulatory approach to encourage significant investment in energy efficiency, renewable generation, and new transmission. A portfolio of tools—regulatory as well as market based—to achieve the radical reductions in GHG emissions necessary to stabilise the climate, is also suggested. The author argues that issues like transmission access and Power Purchase Agreements are just as important to renewable technology investors as the price they would get for their power. Indeed, price incentives alone are not sufficient for steady development and deployment of new technologies. Suggesting a multi-attributes evaluation, the paper concludes that successful renewable technology deployment policy must pay attention to much more than price alone; contract structure, interconnection issues, and a variety of other considerations are also important.
