APS's New Substation Plans

Hi everyone, welcome back to WilliamsLuxuryHomes.com. Over the past few weeks we’ve been talking about major moves shaping Arizona’s Silicon Desert. We’ve touched on TSMC’s massive water plant, the ripple effect on neighborhoods across The Valley, and the billion-dollar projects that are reshaping real estate. Now, a new announcement is here. APS has secured land for a critical substation at Halo Vista, the planned city-within-a-city just north of TSMC. This isn’t just an energy story, it’s the kind of news that fuels growth, development, and the housing market across North Phoenix.

Quick Points

• APS acquires 55 acres for new substation at Halo Vista
• Substation will support TSMC’s expanding $165B site
• Power boost will serve long-term growth for North Phoenix
• Halo Vista master plan spans 2,300 acres with $7B investment
• NorthPark community south of TSMC could add 19,000 homes

APS Steps In Early

APS paid $25 million for nearly 55 acres within the Halo Vista development to build the substation. It’s designed to handle 230-kilovolt underground transmission lines, initially aimed at supplying TSMC’s expanding fab campus. But make no mistake, this is about more than one project. APS is locking in capacity to handle an onslaught of demand over the next 5 to 20 years.

• Supports advanced manufacturing growth in The Valley
• Reinforces long-term energy security
• Aligns with Arizona’s economic development vision

By securing power early, APS is helping future-proof the north Phoenix corridor where factories, offices, and homes are being planned at lightning speed.

The Rise Of Halo Vista & NorthPark

Halo Vista itself is no small plan. Backed by Mack Real Estate Group and McCourt Partners, it covers 2,300 acres with a $7 billion investment. Nearly 30 million square feet of office, retail, and industrial space are expected, along with up to 8,960 residences. Just south of TSMC, NorthPark could add as many as 19,000 homes, creating one of the largest residential waves in Arizona’s history.

• Halo Vista includes office, industrial, and retail centers
• Residential options tied directly to tech job inflows
• NorthPark preparing for massive housing demand

Together, these master-planned communities position North Phoenix as a powerhouse hub for tech, housing, and investment opportunities.

TSMC, Water, & Sustainability

Earlier, we highlighted TSMC’s new industrial water reclamation facility that will recycle up to 90% of the water used in chipmaking. This project signals sustainability is being built alongside growth. With APS now planning its substation and water being secured, infrastructure is falling into place. These moves reassure buyers and investors that the Arizona real estate market isn’t just growing, it’s preparing for the future.

• Water recycling tied to long-term stability
• Utilities scaling alongside semiconductor expansion
• Confidence rising in property values across The Valley

Why It Matters For Real Estate

From Peoria to Scottsdale, from resale homes to new builds, demand is tied directly to announcements like these. When energy, water, and jobs align, buyers take notice. APS’s commitment to supplying Halo Vista and TSMC ensures growth won’t be slowed by infrastructure gaps. That’s a big deal for homeowners, investors, and anyone betting on Arizona’s Silicon Desert.

The future is clear. With Halo Vista, NorthPark, TSMC, and now APS in the mix, North Phoenix is fast becoming a magnet for tech, jobs, and housing. We’ll continue tracking the momentum right here at Williams Luxury Homes. If you’re considering making a move, this is the time to start positioning yourself for what’s ahead.
