Blackstone Infrastructure has agreed to take TXNM Energy private for $61.25 a share in cash, valuing the New Mexico- and Texas-based utility at roughly $11.5 billion including debt. The price represents about a 15% premium to TXNM’s closing price on the 16th of May, and ending the company’s decades long run on the New York Stock Exchange.
- Surging demand: TXNM’s two regulated utilities, Public Service Company of New Mexico (PNM) and Texas-New Mexico Power, supply electricity to about 800,000 homes and businesses.
- Stable returns: As regulated monopolies, the utilities earn roughly 10% allowed returns on new capital. Blackstone is funding the deal entirely with equity, banking on decades of predictable cash flow rather than leverage-driven gains.
- Clean-energy build-out: PNM must hit New Mexico’s 2045 carbon-free target, while TNMP is expanding wires and substations in fast-growing Texas. TXNM expects to spend about $1.3 billion this year alone; Blackstone’s “patient capital” is meant to accelerate that timetable.
The transaction needs approval from regulators in New Mexico, Texas and Washington and, if all goes well, it is slated to close in the second half of 2026. Blackstone has promised to keep TXNM’s headquarters, workforce and union contracts intact and says it will not add extra debt, avoiding the fate of Avangrid’s failed 2021 bid for the same New Mexico utility.
Blackstone takes TXNM private for $11.5B (15% premium)
Surging demand
TXNM’s regulated utilities (PNM and TNMP) supply roughly 800,000 homes and businesses with energy. With record-breaking US power demand looming, that customer base is a gold mine of predictable kilowatt-hour sales.
Stable returns
As regulated monopolies, PNM and TNMP lock in roughly 10% allowed returns on new capital. Blackstone’s all-equity financing play is less about financial engineering, more about decades of slow-and-steady cash yield.
Clean-energy build-out
PNM must hit New Mexico’s 2045 carbon-free mandate while TNMP races to wire Texas’s boomtowns. Blackstone’s “patient capital” should speed up those grid-modernisation projects.
The deal needs sign-offs from New Mexico’s PRC, the Texas PUC, and the US FERC. Blackstone vows to keep HQ, workforce, and union contracts intact… an olive branch to regulators still scarred by Avangrid’s failed 2021 bid for PNM.
Expected closing: H2 2026, pending approvals.
The reality is that US electricity demand is climbing to record highs, in large part because of new energy-intensive technologies and broader electrification.
In fact, 2025 is on track to see all-time peak power consumption. It’s no coincidence this is happening amid explosive growth of AI and cryptocurrency-driven data centers (as well as rising usage in homes and businesses). Companies racing to deploy AI require massive server farms which use a huge amount of energy. A Department of Energy-backed study estimates that power demand from data centers will nearly triple in the next three years, possibly accounting for 12% of all US electricity consumption. That’s an incredibly big jump attributable to AI and cloud computing needs. Crypto mining, while a smaller slice, is also significant, with recent analyses suggesting that mining already accounts for roughly 0.6%–2.3% of US electricity usage.
This surge in demand is straining existing infrastructure and necessitating major grid upgrades. Much of the US transmission and distribution grid is aging and not designed to handle such high loads or the intermittent flows from renewable energy. Industry experts warn that up to $2 trillion of investment may be needed by 2030 just to modernize and maintain grid reliability.
Utilities must expand capacity, harden their networks, and integrate technologies (like battery storage and smart grids) to support both booming data center clusters and emerging needs such as electric vehicle charging.
By targeting TXNM, Blackstone is positioning itself at the nexus of these demand drivers, aiming to provide the capital for capacity expansion and grid resiliency projects required to keep pace.
