By Daniel Roth­berg, Las Vegas Sun:  (TNS) — Elon Musk is lob­by­ing Nevada law­mak­ers to sup­port the devel­op­ment of rooftop solar energy, and he’s doing it with a face-​​to-​​face approach.

Musk, the chair­man of SolarCity and CEO of Tesla Motors, wel­comed a group of leg­is­la­tors and a state gov­ern­ment leader to his company’s $5 bil­lion Nevada bat­tery fac­tory this evening to dis­cuss how Tesla’s home stor­age bat­ter­ies can work in lock­step with rooftop solar.

The event, with pre­sen­ta­tions from Tesla and SolarCity, is meant to be forward-​​looking and edu­ca­tional but fol­lows a recent reg­u­la­tory rul­ing to increase solar cus­tomers’ bills. That order was derided by solar advo­cates and prompted SolarCity to cease instal­la­tions here. The meet­ing rep­re­sents the Sil­i­con Val­ley entrepreneur’s most pub­lic acknowl­edg­ment of the deci­sion and the solar industry’s push to roll back the new rate structure.

At 6 p.m., law­mak­ers and Gov. Brian Sandoval’s top eco­nomic devel­op­ment offi­cer started a tour of the Tesla Gigafac­tory, for which Musk’s elec­tric car and bat­tery com­pany received more than $1.3 bil­lion in incen­tives dur­ing a spe­cial leg­isla­tive ses­sion in 2014. The group will then hear pre­sen­ta­tions from Tesla’s top tech­nol­ogy exec­u­tive and SolarCity CEO Lyn­don Rive. Musk, Rive and Nancy Pfund, a clean energy investor in both com­pa­nies, will par­tic­i­pate in a con­ver­sa­tion with the state offi­cials, a SolarCity spokesper­son said.

Actor and activist Leonardo DiCaprio, who was at the Gigafac­tory Wednes­day for a meet­ing, met sev­eral of the atten­dees who par­tic­i­pated in the event.

In Jan­u­ary, Pfund, a man­ag­ing part­ner at DBL Part­ners, wrote a let­ter with Sil­i­con Val­ley investors that crit­i­cized the state’s Pub­lic Util­i­ties Com­mis­sion deci­sion to raise costs for all rooftop solar cus­tomers. The com­mis­sion tripled a fixed fee for the cus­tomers and slashed the value of cred­its they receive for gen­er­at­ing excess elec­tric­ity to the grid.

I stand by my belief that when a state has a chance to lead, as Nevada has and could con­tinue to do, that sends a very pos­i­tive sig­nal to investors,” Pfund said. “When it steps back, that sends a not-​​so-​​positive message.”

Pfund cast the event as an oppor­tu­nity to dis­cuss how Nevada could remain on the cut­ting edge of clean energy devel­op­ment. Nevada, she noted, had been a leader in solar job cre­ation and in bat­tery production.

The one-​​two punch there is quite com­pelling,” she said. “We need to talk about how to regain the lead­er­ship that pol­i­cy­mak­ers in this state have been forg­ing for sev­eral years now.”
