The Texas Grid.
What homeowners need to know.

What's happening

The Texas electric grid, operated by ERCOT, is the only grid in the continental U.S. that runs largely independent of its neighbors. That isolation lets Texas move fast. But it also means there's no neighbor to lean on when something breaks.

Two forces are colliding right now. Demand is climbing faster than the grid is being upgraded. And weather events that used to be once-in-a-decade are now showing up every few years. The result is a grid that works most of the time, but fails harder than it should when it doesn't.

Why demand is rising

Three trends are stacking on top of each other. Population growth is adding hundreds of thousands of homes a year. Industrial electrification is bringing factories, mining, and oilfield operations onto the grid that used to run on diesel or gas. And AI data centers, the biggest single new load on the grid in decades, are landing in Texas because power is cheap and permits are fast.

The problem isn't supply on a normal day. The problem is the peaks. A summer afternoon in Houston when everyone runs air conditioning at the same time. A January morning when a freeze knocks out gas plants. Those peaks are getting taller, and the gap between average load and peak load is what makes the grid fragile.

"The Texas grid is being asked to do twice as much work in half the margin it used to have."

What changed after Winter Storm Uri

In February 2021, Winter Storm Uri pushed ERCOT minutes away from a months-long blackout. Generators froze. Gas wells froze. Wind turbines froze. The grid lost roughly a third of its capacity at the moment demand peaked. The state passed within four minutes of an uncontrolled grid collapse.

246 Texans died. 4.5 million homes lost power. Damages topped $195 billion. The political and regulatory response was the largest grid reform in Texas history.

1. 2021
   Senate Bills 2 & 3 signed

   Mandatory weatherization of power plants and gas wells. Texas Energy Reliability Council established. Emergency communications standardized.

2. 2022
   Battery storage explodes

   Utility-scale battery deployment in Texas grows 10× in a single year. Storage starts arbitraging the daily peak.

3. 2023
   VPP pilot approved

   Public Utility Commission of Texas authorizes a Virtual Power Plant pilot. Networks of home batteries acting as a single grid resource.

4. 2024
   Permian Basin Reliability Plan

   $8B in transmission upgrades to West Texas, partly to handle oilfield electrification and bring more renewables on.

5. 2025
   VPP rules expanded

   Residential battery systems can now participate in ERCOT ancillary services markets. Homes can get paid for grid support.

Why battery storage matters

Solar makes power when the sun is up. The grid needs power most when the sun is going down. Air conditioning at sunset, winter mornings before dawn. Batteries are the bridge.

A single home battery stores roughly a day's worth of essential load. Thousands of home batteries, coordinated, behave like a small power plant. That's the Virtual Power Plant model. Texas is the first U.S. state to put serious rules and money behind it.

What this means for homeowners

The short version: the grid is shifting from a one-way pipe (utility → home) to a two-way network. Homes with solar and storage become participants in the grid, not just consumers of it. That changes the economics in three ways.

1. Delivery fees stop scaling with you. The portion of your bill that pays for poles, wires, and transmission charges, typically 30 to 50% of a Texas residential bill, shrinks as you self-generate.
2. Outages stop hitting you the same way. A battery sized for essentials keeps lights, fridge, internet, and medical equipment running for the duration of most outages.
3. You can earn from the grid. When ERCOT calls a VPP event, qualifying batteries dispatch stored energy and the homeowner gets paid.

How Gridhack fits into the solution

Gridhack is a utility swap. We install rooftop solar and a home battery at no cost to the homeowner. The homeowner stops buying energy from the utility and starts buying it from the system on their roof at a true flat rate, with no delivery fees layered on.

Every home we put a system on does three things at once: it takes one household off peak utility demand, it adds distributed generation back into the local grid, and it adds battery storage that can be coordinated into a VPP. The aggregate effect is less stress on transmission infrastructure already strained by AI and data-center load, and more resilience for the homeowner when the grid fails.

"Every install is one less home on the peak. Multiply that by ten thousand homes and you've built a power plant nobody had to permit."

See if your home qualifies

Eligibility is mostly a question of territory and roof. We've verified the buyback rates and net-metering rules in Oncor, CenterPoint, CPS, Rocky Mountain Power, and Xcel territory. If you're in one of those, the program applies to you. Roof condition and shade are the other two main factors, and we check both before designing anything.
