EVwire brief: Resound Energy, the Washington installer behind EVODS' recent Supercharger site, has opened the first Tesla Supercharger for Business site that it owns and operates itself, a six-stall V4 station at Redmond Town Center in Redmond, Washington.
Resound handled the whole build itself. The project included a new 800A, 480V electrical distribution system, utility transformer connections and primary conduit, feeder and branch circuits, and the wiring between the Tesla Power Cabinets and the chargers. The civil side covered excavation, backfill, concrete, asphalt restoration and parking stall striping, plus protective bollards to shield the stalls in the busy retail lot.
In a statement to EVwire, Resound founder Neil Sainsbury-Carter explained why the company is now keeping some sites for itself:
"We've been building these types of charging sites for our customers for years, and owning and operating them ourselves gives us firsthand experience that helps us better understand the needs of our customers and continue improving the turnkey services we provide. We also see these sites as a strong long-term investment, with the potential to generate recurring revenue while expanding access to public EV Charging."
Here are more photos of the Redmond site, as shared to EVwire:

Building Supercharger for Business sites is familiar work for Resound. The company also installed EVODS' six-stall V4 site in East Wenatchee, which opened earlier this month with a similar 800A, 480V electrical system and civil package.
Resound, based in Woodinville, Washington, has designed and installed EV charging and LED lighting since 2007, and says it has put in more than 8,000 EV charging ports across Washington, Oregon, Colorado, Minnesota and Northern California.

The station sits at 7597 170th Ave NE and appears on Tesla's Find Us map as the Resound Energy Supercharger. Its six stalls are rated at up to 325 kW and are available 24/7, though Tesla's listing doesn't show pricing yet. Here's the location as shown on the map:

Context:
Resound's new station runs on the Supercharger for Business model Tesla launched in September 2025, which lets third parties own Supercharger sites while Tesla handles the network side. Hosts pay for installation and electricity, set their own charging prices and can brand the stalls, while Tesla supplies the hardware, commissions the site and runs 24/7 remote operations with a 97% uptime guarantee.
Tesla's Supercharger cost calculator puts turnkey installation at $45,000 to $65,000 per post, with a four-stall minimum per site, and revenue-generating sites pay Tesla an all-inclusive $0.10/kWh fee under a 10+ year service agreement.
Resound isn't the only company that started out building Superchargers for others and is now taking on more of the network itself. Roam Energy, a Tesla Certified Installer, handles everything from site acquisition and construction to ongoing network operations and maintenance for its Supercharger for Business sites in Alabama and North Carolina.
