A new analysis from university-based and national laboratory researchers applied a new modeling approach for long-term electricity generation infrastructure planning that considers future climate and water resource conditions.

Compared to traditional projections, which do not consider climate-water impacts on electricity generation, results of this new approach show the national power grid may need an additional 5.3 per cent to 12 per cent of power-generating capacity to meet demand and reliability requirements.

The changes would lower water use and carbon emissions, potentially helping mitigate future climate changes.

The new study, which will be featured as the cover article in the December 3 online and December 13 print issue of Environmental Science & Technology, is available online today.
