As Colorado and other states increase the levels of renewable energy on their system, it raises the question of how much renewable energy can be accomodated on the grid given issues of variability and uncertainty. A recent detailed analysis gives an optimistic answer and outlines what needs to be done.
After two and a half years of study, a large team of researchers from the National Renewable Energy Laboratory in Golden along with other utilities and industry experts, released the long-awaited Western Wind and Solar Integration Study which concluded that for a group of Western utilities known as “West Connect” it is possible to accomodate up to 30% wind and 5% solar energy if additional efforts are made to increase the level of cooperation between what are known as balancing areas and to incorporate state of the art forecasts and other tools that will allow the grid to respond as renewable energy increasingly displaces fossil fuel generation.
The Western Wind and Solar Integration Studies can be accessed here. The Executive Summary is attached below.
