Another week brings more moves and shifts at the upper levels of the renewable energy industry.

Before founding the just-unstealthed Voltus last year, CEO Gregg Dixon was a senior VP and a founding executive at EnerNOC. Voltus is a challenger to EnerNOC, as is long-standing competitor CPower. In March, EnerNOC CEO Tim Healy said the firm was exploring "potential alternatives to our current structure. This may include the sale or separation of one or more of our business units, a sale of the company, or other alternatives." (Jeff St. John reports on Voltus here.)

Last week we reported that Jon Wellinghoff, the chief policy officer at SolarCity, had left the company now that it has merged with Tesla. The ex-FERC commissioner just told GTM:

"My move in opening my own firm, Policy/DER Consulting, will allow me to better focus on my passions: energy policy and its intersection with distributed energy resources. I see a rapid movement now happening from the old way of siloing technologies like rooftop solar, efficiency, storage, and control technologies to an integration and optimization of systems behind the meter. In order to effectively enable this transition, significant policy initiatives will be necessary. Those initiatives include the creation of efficient transactional financial market platforms based on backend algorithms like blockchain. Having my own firm allows me to fully explore and engage these new paradigms."

William Stanton, most recently with Belectric, is now VP of engineering for Blue Oak Energy, a solar engineering firm. Blue Oak has a portfolio of 1.5 gigawatts of operational solar generation across the Americas. Stanton also served as director of global project permitting at First Solar. Blue Oak Energy is a wholly owned affiliate of Coronal Energy and Panasonic.

JLM Energy, a renewable energy technology firm, added Erin Clark as COO. Clark most recently served as president of nationwide roofing and solar contracting firm PetersenDean.

Peter Olmsted is now Assistant Secretary of Energy at the New York State Office of the Governor. He was previously with the New York State Department of Public Service and Vote Solar.

Tom Weirich, previously with ACORE, is now director of marketing and business development at investment bank CohnReznick Capital.   

Matthew Culligan, with SunPower since 2007, has joined solar tracker standout NEXTracker as director of sales operations.

Christopher Sommerfeld was promoted to director of field efficiency and quality at Sunrun.   

Dawn Roiz recently left the now-bankrupt California solar installer HelioPower to join Associated Construction & Engineering as controller. PV magazine reports that HelioPower filed for Chapter 11 bankruptcy protection on Wednesday and estimates it owes its employees approximately $124,000 in wages.
