Knowledge Gaps Analysis
In March 2019, NREL issued a request for information to identify knowledge gaps on implementing IEEE Std 1547-2018. Responses to the request for information are being used to help identify key priority areas, which will inform the development of new educational material. We encourage you to support this effort by providing your input to the latest Knowledge Gaps Analysis. If you notice any gaps we haven't identified, please provide your own feedback by taking our survey (available in English and Spanish).
