Last month, GTM covered the resignation of NRG Energy CEO David Crane from a post he’d held since 2003. Also resigning from NRG recently was Robyn Beavers, the "founder and leader of the newly formed Station A Group, a microgrid skunk works within the power company."

GTM has now learned that Tom Doyle, the CEO of NRG Renew, has left the firm. NRG has confirmed.

Recently, GTM reported that Steve McBee, CEO at NRG Home for a little more than a year, will be leaving NRG as well.

In 2014, Wilson told GTM, "NRG has decided to be a leader in residential solar." John Ragan, EVP and president of the Gulf Coast region, has also left the firm, according to reports.
