On February 11, 2019, a group of seventeen Democrat United States Senators and Senator Bernie Sanders wrote a letter (the “2019 Letter”) to FERC Chairman Neil Chatterjee urging FERC to adopt a rule requiring Regional Transmission Organizations (“RTOs”) and Independent System Operators (“ISOs”) to open their markets to participation of aggregated distributed energy resources (“DERs”).

This 2019 Letter follows a previous, similar letter sent to then-Chairman Kevin McIntyre on May 23, 2018 by a group of most of the same Senators (the “2018 Letter”).  In April 2018, FERC held a technical conference to discuss the participation of DERs in markets operated by RTOs and ISOs, but as of this writing, has not taken any other action on the matter.

Both the 2018 Letter and the 2019 Letter referenced Order No. 841 from February 15, 2018, in which FERC required that RTOs and ISOs open their markets to participation by energy storage resources (see February 20, 2018 edition of the WER).  The Senators urged Chairman Chatterjee to adopt a similar rulemaking with regard to DERs, stating that such rulemaking would both improve the reliability and resilience of the bulk power systems and could also lower the costs for consumers.
