Four years. Four-hundred-and-ten-thousand megawatts. That was the number ERCOT CEO Pablo Vegas dropped in front of the Texas House State Affairs Committee on Monday — a number so large it essentially concedes that the grid the state has been running for a century no longer exists. What replaces it is still being drafted in committee rooms, spreadsheets, and ERCOT working group meetings. We got a preview this week.
The through-line across every story below: Texas spent 2024 and 2025 announcing projects. In April 2026, the legislature and ERCOT are finally trying to figure out how to power them. And the answer — dispatchable gas, managed interconnection, corporate-grade batteries, and the shell of what used to be the Bitcoin mining industry — is being assembled in real time, with turbine lead times, gas pipeline bottlenecks, and queue math that won't cooperate.
"410,000 Megawatts in Four Years": ERCOT Brings the Number to the Capitol
Pablo Vegas testified to the House State Affairs Committee on April 13 with a figure that should have cleared the room. Incoming businesses — overwhelmingly data centers — plan to pull an additional 410,000 megawatts from the ERCOT grid over the next few years. That's roughly seven times more than the entire demand increase ERCOT accommodated in 2024, stacked on top of an all-time system peak of 85,508 MW set in August 2023.
The committee's projection of ERCOT load by 2032 is now 367,790 MW — 4.3x current peak demand. Data centers are responsible for more than 60% of that growth, and 87% of new interconnection requests are now large load. One announced Abilene campus alone will draw 1.2 GW across eight buildings.
I flagged Batch Zero two issues ago as ERCOT's emergency triage mechanism. This week it stopped being a theory. Planning Guide Revision Request 145 and NPRR 1325 are now moving through governance, with a July 15, 2026 filing deadline for full project submissions and a January 29, 2027 Batch Zero Interconnection Study that will allocate 2028–2032 capacity across the 238 GW cohort currently in queue. The study is the decision point. Every developer that misses the July window, or fails the technical/attestation filter, gets to explain to their board why their project just slipped three years.
Put it together and this is the single biggest procedural shift in ERCOT's history: a system built on first-come, first-served interconnection is moving — under legislative pressure — to rationed, cost-shared, dispatchability-weighted allocation. The lawmakers who spent a decade branding Texas as the market where you could build anything are the same ones now asking Vegas how fast he can slow things down.
The Great Miner Sell-Off: Core Scientific, CleanSpark, and Bitfarms Dump BTC to Fund the AI Pivot
Riot signing AMD a few weeks ago was the proof of concept. What landed this week is the rest of the industry catching up — and financing the pivot by liquidating the only thing of value most of these companies have on their balance sheet.
Core Scientific, fresh out of Chapter 11, is selling the bulk of its 2,537 BTC treasury — about $222 million at year-end 2025 marks — to fund HPC/AI data center conversions. Roughly 1,900 BTC were already off the books in January for $175 million. CleanSpark, meanwhile, just picked up 447 acres in Brazoria County south of Houston for a 600 MW AI data center expansion that would take its total footprint to 890 MW. Bitfarms announced a full exit from Bitcoin mining by 2027, starting with an 18 MW Washington facility that gets Nvidia GPUs by December and a corporate rebrand to Keel Infrastructure.
The math on why is brutal for BTC bulls and great for ERCOT. Riot's Corsicana AMD lease is projected to generate 2.5x the profit per megawatt of mining, with $1.6 to $2.1 billion in NOI at full 1 GW build-out. Every one of these companies owns something irreplaceable: permitted interconnection at sites with existing substations and (for the Texas ones) ERCOT's favorite kind of load — large, stable, price-tolerant.
The grid reliability story is almost better than the business story. Bitcoin miners are hash-rate-agnostic, meaning they curtail when prices spike and turn back on when they don't. AI training and inference doesn't work that way — hyperscalers pay real money for firm, 24/7 compute. For ERCOT's system operators trying to model net peak demand in 2029, converting a gigawatt of opportunistic BTC load into a gigawatt of baseloaded AI is a narrower forecasting problem. For the miners, it's the only trade available.
Permian Gas Crashes to Negative $5.66 While Nobody Can Build a Turbine
Here's the paradox the legislature is not going to fix in one session. Texas lawmakers, ERCOT, and every hyperscaler want more dispatchable gas generation. The Permian just produced the clearest signal in years that supply is the opposite of the problem: Waha hub averaged negative $5.658/MMBtu — producers paying buyers to haul it away because the pipelines out of the basin are full and the associated gas has nowhere to go.
You would think $5.66-of-free-money gas would be rocket fuel for new combined-cycle plants. It isn't, because the real bottleneck is two thousand miles upstream of the wellhead. Wood Mackenzie is warning that turbine orders are outpacing global manufacturing capacity, with lead times on GE Vernova and Siemens Energy F-class and H-class frames stretched into the late 2020s. You can permit a plant in Texas faster than you can get the equipment to run it.
This is the quiet constraint on everything in the first story. ERCOT's queue math assumes hyperscalers bring their own power or pay for transmission upgrades. Most of the credible behind-the-meter plans are gas. Gas plants need turbines. Turbines don't exist yet. Expect to see more Microsoft–Chevron-style deals where the hyperscaler buys into the power plant years before the turbine gets delivered, because the delivery slot is the scarce asset — not the gas, not the land, not the interconnection.
GridStor Doubles Down: 220 MW in Galveston Live, 150 MW in Hidalgo Tolling a Fortune 500
Battery storage keeps showing up in this newsletter for a reason. ERCOT's BESS fleet crossed 15 GW at the end of Q1 2026 with another 1.1 GW across 20 projects reaching commercial operation in the quarter. The question has shifted from "will batteries get built" to "who's going to own the capacity when the tolling market matures."
GridStor, the Goldman Sachs–backed pure-play operator, is one answer. Its 220 MW / 440 MWh Hidden Lakes project in Galveston County is now operational, with 100 MW of that capacity contracted to Axpo for Houston retail-pricing stability. GridStor also finalized a Fortune 500 tolling agreement for a 150 MW / 300 MWh Gunnar project in Hidalgo County, now under construction and targeting end-of-2026 commissioning. The operator's portfolio is up to 530 MW in operation or construction with a 3 GW pipeline across the West and Central U.S.
Two points worth internalizing. First, merchant BESS is no longer the only model. Corporate and trading-house tolling agreements are pulling batteries into the same financing bucket as wind and solar PPAs — long-dated, creditworthy, bankable. Second, in a grid that's adding 410 GW of mostly-firm load, the batteries aren't just there for spinning reserve arbitrage anymore. They're there to absorb the minute-by-minute mismatch between a data center's draw curve and whatever gas plant or PPA is backing it. That's a utility function, priced like utility infrastructure.
What to Watch This Coming Week
The ERCOT Board of Directors meets April 23–24. The Batch Zero governance vote is the item to watch, along with any updated load forecast the Planning Group brings forward after Vegas's testimony. Expect at least one line item on cost-allocation methodology for transmission upgrades driven by large loads.
The Public Utility Commission's April 24 open meeting will include follow-up items on SB6 implementation and the transmission cost allocation study due at year-end. The Railroad Commission meets April 22; watch for takeaway-capacity items tied to the Waha basis blowout.
Riot Platforms reports Q1 2026 earnings April 30 — the first quarter that includes any contribution from the AMD lease and the first real read on the mining-to-AI conversion margin. Meta, Amazon, and Google all report the prior week. Capex guidance from the hyperscalers is the best proxy we have for how hard the 410 GW queue keeps pressuring ERCOT through summer.
Finally, watch GE Vernova's Q1 call for turbine backlog commentary. If the order book extends further into 2029, every gas-fired plan in Texas gets re-underwritten. Including the ones the legislature just told ERCOT to prioritize.
