ERCOT's New Large-Load Interconnection Process: What Bitcoin Miners Need to Know

Tomorrow (July 10), ERCOT's old interconnection process shuts down. The new Batch Zero framework changes how every large load in Texas connects to the grid.

TLDR

• ERCOT is tracking more than 438,000 MW of new connection requests from large electricity users. Nearly 90% are from data centers. For context, ERCOT's all-time peak demand record is 85,508 MW.
• The new Batch Zero framework studies all projects 75 MW or larger together rather than one at a time. July 10 is the deadline to submit required technical studies and documentation. ERCOT will notify applicants of their classification by August 7.
• The framework introduces two new pathways — PCLR and WLPUN — that let large loads connect faster by agreeing to curtailment or bringing their own generation. Bitcoin miners already operate as curtailable loads in ERCOT.

Tomorrow is the last day of the old system. July 10, 2026 is the deadline for projects wanting to be part of Batch Zero to submit required technical studies and documentation to ERCOT.

Why the old process broke

Texas is experiencing an unprecedented surge in demand for electricity. Data centers, cryptocurrency operations, and large industrial plants are requesting to connect to the ERCOT grid at a rate never seen before.

As large users rushed to connect, ERCOT discovered that studying connection requests one at a time was no longer viable. Each new large project affected and could potentially invalidate studies for projects already farther along in the process, triggering costly restudies and delaying completion timelines.

The backlog now totals more than 438,000 MW of proposed demand, with nearly 90% from data centers. ERCOT's all-time peak demand record is 85,508 MW. The queue is more than five times the grid's record load.

How Batch Zero Works

Under the new framework, ERCOT studies all eligible projects 75 MW or larger together. ERCOT assesses how all the projects interact with each other and with the existing grid, producing a single, coordinated picture of what transmission upgrades are needed.

Key dates per ERCOT:

• July 10, 2026 — Deadline for projects to submit required technical studies and documentation
• August 7, 2026 — ERCOT notifies applicants of project classification (Base Load, Studied Load, or Excluded)
• Spring 2027 — ERCOT provides each large user with the amount of electricity that can reliably be allocated for their project
• Q2 2027 — Deadline for proof of developer commitment (financial security and site control)
• Fall 2027 — A final transmission plan allocating the load and prescribing updates is published

Applications for Batch 1 will be accepted beginning in summer 2027.

Each project entering Batch Zero is classified into one of three categories. Base Load projects completed prior studies meeting defined criteria — their allocated capacity from prior work is effectively preserved. Studied Load projects have some study work completed but their allocation hasn't been predetermined — they may receive full requested capacity, a partial allocation, or may need to wait for a subsequent batch. Excluded projects do not qualify and must wait for a future batch study.

Two new pathways that reward flexibility

Batch Zero introduces two optional pathways for large customers who want to connect in ways designed to reduce pressure on the transmission grid.

Provisional Controllable Load Resource (PCLR): Large customers agree to let ERCOT reduce their power consumption during periods of localized stress on the grid. The customer embeds controllable load into ERCOT's dispatching system and ERCOT can curtail their power use when transmission constraints arise. In exchange, the customer can access a portion of the grid ahead of a full transmission buildout. ERCOT describes it as a "reliability partnership" — the customer consumes more power when the local grid is moving freely, and ERCOT gains a tool to automatically reduce that draw during congestion.

Withdrawal-Limited Private Use Network (WLPUN): Large customers who plan to build their own on-site generation — natural gas turbines, solar panels, or other sources — reduce the amount they draw from the grid. The framework recognizes that contribution and allows on-site generation to offset the transmission capacity required, making it easier to connect at higher load levels.

Where miners fit

Nearly 90% of the 438,000 MW queue comes from data centers. But that label covers a widening range of operations, including Bitcoin miners who are increasingly co-locating AI workloads on the same power infrastructure.

Miners bring something most facilities in that queue cannot offer: the ability to curtail power consumption to near-zero within minutes, without equipment damage or lost product. That distinction maps directly onto the PCLR pathway. Accepting dispatch and curtailment obligations in exchange for grid access is not a concession for miners — it is how they already operate. Bitcoin miners are classified as Controllable Load Resources in ERCOT, making them eligible for ancillary services and the real-time energy market.

Miners who are already connected and operating are positioned for Base Load status under the new framework, meaning their capacity is preserved without further evaluation. For miners planning new sites or expansions, Batch Zero's flexibility pathways create a structured route to interconnection that rewards the load profile mining already offers.
