Texas has become the dominant US market for both data center development and Bitcoin mining operations for a simple reason: ERCOT's deregulated electricity market offers competitive supply rates unavailable in most of the country, combined with abundant cheap wholesale power from wind and solar overproduction. But accessing those advantages requires navigating Texas commercial electricity procurement correctly — and most new operations in this sector don't.
A Texas data center or mining operation that enrolls on a basic retail fixed-rate contract is accessing perhaps 20% of what the Texas market offers for large power consumers. The most favorable economics for high-load Texas operations come from Primary Service rate classifications, demand response program participation, and large-account procurement structures that most small brokers and direct REP relationships don't offer. This guide covers each of these specifically.
The meter classification your operation falls under determines your TDU delivery charges and which supply contract structures are available. For data centers and mining operations, this classification can represent a significant cost difference.
Secondary Service under 10 kW: Small operations only. Not applicable to data centers or meaningful mining operations.
Secondary Service over 10 kW: Small to medium commercial accounts. For data center or mining operations in this classification, standard commercial supply contracts apply. Delivery charges in Oncor territory: approximately 3.5–4.5¢/kWh all-in.
Large Secondary Service: Medium-to-large commercial accounts. For Oncor territory, this classification covers accounts with demand between approximately 50 kW and 1,000 kW. Delivery charges are structured differently than smaller accounts, typically with a larger demand component and lower energy component.
Primary Service: Accounts above approximately 1,000 kW that own their own high-voltage transformers. Primary Service accounts have the lowest per-kWh delivery charges in Texas — but require significant infrastructure investment in customer-owned transformation equipment. For large data centers and industrial mining operations, Primary Service classification dramatically improves total electricity economics and is worth evaluating at any load above 500 kW.
Identifying the correct classification for your operation and understanding whether reclassification makes economic sense requires working with your TDU directly or with a broker familiar with large commercial account structures in Texas. The classification affects not just your current bill but every future procurement and the economics of any expansion.
Supply rate benchmarks for Texas data center and Bitcoin mining operations from competitive auctions as of April 2026:
Small data center or colocation (50,000–200,000 kWh/month, 75–300 kW demand): 7.4–8.8¢/kWh supply for 24-month fixed contracts in Oncor territory. These accounts benefit from high load factor (servers run continuously at high utilization) which produces favorable bids. Accounts that enrolled directly with a provider at buildout without competitive procurement are frequently paying 9.5–11¢/kWh.
Medium data center or mining facility (200,000–1,000,000 kWh/month, 300 kW–1,500 kW demand): 7.0–8.2¢/kWh supply rate from competitive auctions. At this scale, the account is attractive to most Texas REPs and the auction produces competitive bidding. All-in rates with delivery (Large Secondary Service classification): approximately 11.5–14.0¢/kWh.
Large data center or mining campus (1,000,000+ kWh/month, 1,500+ kW demand): 6.5–7.8¢/kWh supply rate from competitive auctions. At this scale, Primary Service classification significantly reduces delivery charges. The most competitive forward contracts include indexed components and demand response provisions that reduce total delivered cost below what fixed-rate supply alone produces. Operations at this scale should work with a broker experienced in large commercial Texas procurement.
ERCOT operates several demand response programs that pay large commercial customers to reduce load during grid stress events. For data centers and mining operations with flexible load management capabilities, these programs represent direct revenue above and beyond the savings from competitive electricity procurement.
Emergency Response Service (ERS): ERCOT pays registered ERS participants to be available to curtail load within 10 minutes during grid emergencies. Payment is for availability, not just curtailment events. Data centers with redundant power infrastructure and mining operations that can shed load quickly are natural candidates.
Controllable Load Resource (CLR): Operations enrolled as CLRs can participate in ERCOT's ancillary services market, receiving payment for providing spinning reserve or non-spinning reserve capacity — essentially being paid to be available to reduce load.
Retail demand response through REP contracts: Some Texas commercial supply contracts include demand response provisions that credit accounts for reducing consumption during defined peak periods. These credits reduce effective all-in rates below the contracted supply rate for operations that participate consistently.
The economics of demand response participation depend on the operation's ability to respond quickly and consistently. Bitcoin mining operations are generally more responsive than data centers because mining rigs can be switched off without affecting stored data. For a mining operation consuming 5 MW, demand response revenue can represent significant additional income that makes Texas's already-competitive electricity rates even more favorable. Our guide on Texas commercial demand charges and demand response covers the mechanics of ERCOT program participation.
Texas is experiencing unprecedented data center development, concentrated in the DFW metroplex — particularly Plano, Allen, and the broader Collin County market directly north of Dallas. ERCOT's 2026 planning documents project 9%+ demand growth in the North load zone specifically, driven by this buildout. This has direct implications for forward contract pricing.
Contracts with summer 2026 and 2027 exposure are incorporating risk premiums for the North zone that reflect expected demand growth exceeding current generation capacity additions. For data center operators procuring electricity in Oncor territory now, 24-month contracts executed in spring 2026 represent the most favorable forward window before summer 2026 demand risk is fully embedded in market pricing. See our ERCOT summer 2026 commercial electricity outlook for the current forward pricing analysis.
The other implication of data center load growth: grid interconnection timelines for new large-load accounts are lengthening. For greenfield data center projects requiring new high-voltage service from Oncor or CenterPoint, starting the interconnection process early and working with the TDU on load profile projections is increasingly important as queue congestion grows.
Bitcoin mining operations have load characteristics that differ from data centers in ways that affect optimal contract structure. Mining load is dispatchable — miners can be turned off with no loss of stored data or ongoing processes. This flexibility is valuable in Texas's ERCOT market and should be leveraged in procurement.
The optimal contract structure for most Texas mining operations combines a fixed base supply rate for the operation's minimum continuous load, with an indexed or spot-priced layer for additional capacity that takes advantage of ERCOT's frequent negative and near-zero price periods (common during windy nights and sunny midday periods). This structure requires an operator with the energy management capability to monitor real-time ERCOT prices and adjust load accordingly.
For operations without dedicated energy management, a fixed-rate contract for the full load — procured through a competitive auction — is appropriate. The simplicity and cost certainty outweigh the potential marginal gains from index exposure for operations below approximately 5 MW.
Yes. Texas wind RECs and solar RECs are among the most cost-competitive renewable energy certificates in the US, given Texas's abundant generation capacity. Green supply contracts backed by Texas wind RECs typically run 0.3–0.8¢/kWh above equivalent conventional contracts for the same account. For data centers with sustainability commitments or customers requiring green energy certification, this premium is often manageable relative to the overall electricity cost structure.
Favorably. A 24/7 continuous high-load operation has an extremely high load factor, which is favorable for procurement. Providers can price steady, predictable loads more aggressively than variable ones. Mining operations often receive the most competitive auction bids relative to their account size because their load profile is simple and low-risk for providers to hedge.
Oncor territory in the DFW metroplex — particularly Collin County (Plano, Allen, McKinney) and Tarrant County (Fort Worth, Arlington) — has seen the largest concentration of new data center development. Oncor's transmission infrastructure, combined with ERCOT North load zone competitive supply rates, makes DFW the most active large-load development market in Texas. Houston (CenterPoint territory) is also growing but at a slower pace due to higher delivery charges.
For large new facilities (above 1 MW): 6–12 months before expected commissioning, to allow time for TDU interconnection, meter installation, ESI ID issuance, and REP enrollment. For smaller buildouts: 60–90 days. Always enroll a competitive supply contract before the first meter read — not after — to avoid default POLR service rates on initial billing.
