The overall goal of the Renewable Integration Impact Assessment (RIIA) is to better understand the impacts of renewable energy growth in MISO over the long term. This assessment will provide technically rigorous, concrete examples of integration issues and examine potential solutions to mitigate them. It will give MISO and its stakeholders specific areas around which to focus effort and help inform the sequencing of actions required to manage certain renewable penetration levels. The assessment will not find all limitations and will not detail all possible solutions, nor attempt to identify best solutions. However, the assessment will include greater details over a wider rand than traditional renewable integration studies. The assessment will illustrate specific areas of system weakness, show when those weaknesses could become problematic and identify potential means to address them. Lastly, the assessment will seek to facilitate a broader conversation about renewable integration impacts on the reliability of the electric system.
