- Sunrun traded at $14.88 premarket after jumping 12.57% to finish at $14.42 on Wednesday. Nasdaq starts regular hours at 9:30 a.m. ET.
- Tesla Inc (NASDAQ:TSLA) and Renew Home have a deal that includes over 16 GW of flexible capacity, but that figure mixes together battery rated capacity and one-hour HVAC load-shift.
- Trading volume on Wednesday reached 53.48 million shares, which is 592% above the 65-day average. As of May 29, short interest in Sunrun stood at 26% of its float.
- Wells Fargo said Sunrun’s connected battery fleet makes up around 0.5 GW of the total pool. GLJ Research put the actual rated power from home batteries at only 4 GW.
Sunrun Inc (NASDAQ:RUN) picked up around $384 million in equity value Wednesday after shares rose $1.61, with 238.55 million shares out. That’s close to $24 million for each gigawatt named in the Tesla-Renew Home deal, before the firms set an offtake price or Sunrun’s revenue cut.
Nasdaq regular trading was not open at the time. Pre-market runs from 4:00 a.m. to 9:30 a.m. ET, with normal hours from 9:30 a.m. to 4:00 p.m. June 25 is scheduled as a regular session in 2026, falling between the June 19 Juneteenth and July 3 Independence Day market closures.
The stock jumped 12.57% Wednesday to close at $14.42, after reaching $16.79 earlier. By 5:44 a.m. EDT Thursday, it was at $14.88 premarket, up 3.19% from the last close.
Sunrun, Renew Home and Tesla said June 24 they will deliver over 16 GW of flexible energy to hyperscalers and utilities. The companies said the agreement uses hundreds of thousands of Sunrun and Tesla home battery systems and more than 8 million smart thermostats and devices managed by Renew Home.
The details are in the footnote. Sunrun clarified it counts battery storage megawatts using installed battery rated capacity. For HVAC, it’s measured by one-hour peak load-shift from thermostats and HVAC systems. So the 16 GW number isn’t a pure generation fleet, it combines battery output with demand cuts.
Sunrun CEO Mary Powell said, “The grid of the 1800s cannot power the innovation of 2026.” Renew Home CEO Ben Brown said “hyperscalers are motivated to drive down costs.” Sunrun Inc.
Wells Fargo’s Praneeth Satish said the deal looks “positive,” but he doesn’t see a big jump in Sunrun’s virtual power plant revenue soon. According to Satish, Sunrun’s networked batteries make up only 0.5 GW, or around 3.1% of the 16 GW announced. TipRanks
GLJ Research’s Gordon Johnson didn’t hold back. He called the 16 GW figure “engineered for a press release, not a power-purchase agreement” and put the real number closer to “only ~4 GW is actual home-battery rated power.” Johnson maintained his Sell rating on the stock. TipRanks
Clear Street’s Tim Moore said the framework is “the most important milestone” so far for Sunrun’s move into distributed power capacity, and stuck with a Buy rating and $24 target. RBC Capital said virtual power plants may boost grid service and help customer costs as more are brought online. TipRanks
Subscriber growth at Sunrun slowed as the core installation business pulled back. First-quarter subscriber adds were down 25% year over year, while solar capacity fell 19% and storage capacity slipped 15%. But storage attachment increased to 73%. Sunrun reported about 4.3 gigawatt hours of networked storage on its books at the end of March.
That’s what pushed the stock beyond a typical partnership move. Locking in repeatable capacity payments gives Sunrun a fresh lever to make money from batteries as rooftop solar weakens. Even if the short-term revenue is limited, Wednesday’s rally comes with 26% short interest, a 16 GW headline, and a 0.5 GW Sunrun battery number to reconcile ahead of the open.
